Fiat Albea. Starting the engine from external current sources

If you cannot start the engine due to partial or complete discharge battery, then you can use the battery of another car to start it. To connect the donor battery, use special connecting cables with alligator clips.

When starting the engine from an additional battery, carefully follow the operating sequence outlined in this subsection.

Otherwise, a fire or explosion may occur, resulting in damage to both vehicles. Therefore, in order to avoid harm to yourself, the car and the battery when starting the engine from an external source, do it as follows. If you are in any doubt, it is highly recommended that you have these operations performed by an experienced technician or towing service. Before connecting the external battery, make sure the ignition is turned off. Also turn off all electrical consumers (headlights, audio system, windshield wipers, etc.). When connecting and disconnecting wires, do not allow them to touch each other, as well as contact of the wires with the fans, drive belts or other rotating parts.

Use only a 12-volt external power supply. If you apply 24-volt power (two 12-volt batteries in series, or a 24-volt motor generator set) to a 12-volt starter, ignition system, or other electrical components, it may cause permanent damage.

Keep open flames or sparks away from the battery. It releases hydrogen gas, which can explode in their presence.

Do not disconnect the external battery cables until the engine is running at normal idle speed. If you leave the audio system on while starting the engine with the auxiliary battery, it may be seriously damaged. Always turn off the audio system before starting the engine from another vehicle's battery.

1. Place the car with a discharged battery next to the donor car within reach of the connecting cables.

Warning

Cars should never touch each other. Otherwise, an unwanted short to ground may occur, resulting in you being unable to start the vehicle's engine with a dead battery and causing damage to the electrical systems of both vehicles.

2. Apply the parking brake to both vehicles.

3. Check the electrolyte level in a discharged battery

If the electrolyte level is very low or the electrolyte appears frozen, do not try to start the engine using an additional battery! In this case, the discharged battery may explode.

4. Remove the cover from the positive terminal of the battery.

5. Attach the connecting cable clamp with red handles to the “plus” terminal of the battery.

6. Connect the second cable clamp with red handles to the “plus” terminal of the “donor” battery.

7. Attach the clamp of the second cable to the negative terminal of the donor battery

8. and the second cable clamp with black handles - to the “ground” of the car with a discharged battery in a place located at the maximum possible distance from the battery.

NOTE
The requirement to connect the wire at a maximum distance from the battery is explained by the possibility of sparking at the moment of connection.

9. Make sure that you connect the cables in the correct order and that they do not come into contact with moving parts of the engine.
10. When using a battery installed on a donor car, start the engine of this car and let it run for several minutes at a speed of 2000 rpm

11. Start the car engine with a discharged battery and let it run until it reaches a stable idle speed.

12. Disconnect the cables in the exact reverse order in which they were connected.

Features of the electrical equipment and engine management system of the Fiat Albea (Added)

The electrical equipment of the Fiat Albea car is made according to a single-wire circuit, the function of the second wire is performed by the car body.

Rated voltage on-board network is 12.6 V, for protection electrical circuits fuses are used.

The electrical equipment includes a battery, a generator, a starter, engine control systems, lighting and light signaling, as well as instrumentation and additional electrical equipment. Let us consider some of the listed systems (nodes) in more detail. In Fig. Figure 1 shows a fragment of a car’s electrical equipment diagram with generator, starter and ignition switch components.

Rice. 1. Fragment of a car electrical circuit with generator, starter and ignition switch components

In table 1 shows the color coding of the installation wires of the electrical equipment of the Fiat Albea car.

Table 1. Color coding installation wires for electrical equipment of a Fiat Albea car

Generator The car has a three-phase generator AC with a built-in rectifier unit based on silicon diodes and an integrated voltage regulator. It is designed to power vehicle consumers with direct electric current and charge the battery.

Structurally, the generator consists of a stator and a rotor. The stator is made in the form of a ring of individual tightly pressed steel plates. On the inside of the structure there is a stator winding consisting of three coils located at an angle of 120° relative to each other. The coils of this winding are divided into three groups, in each group they are connected to each other in series, and the groups are connected to each other by a “star” (some terminals of the three groups are connected to each other, and others are connected to the input of the rectifier).

The output voltage of the generator depends on the rotor speed, the magnetic flux generated by the field winding, as well as on the strength of the field current. The integrated voltage regulator ensures stabilization of the output voltage when the rotor speed and load change. Voltage stabilization occurs by changing the current in the excitation winding by switching the power supply circuit of the excitation winding with a voltage regulator. In table 2 shows examples of the most likely generator malfunctions and the reasons for their occurrence.

Table 2. Generator malfunctions and causes of their occurrence

Starter

The starter is an electric motor DC with electromagnetic traction relay and overrunning clutch. The starter is powered directly from the battery in engine starting mode. When voltage is applied contact group ignition switch to pin “50” traction relay starter, it uses a lever with a fork to move the overrunning clutch along the starter axis and, thereby, mechanically connects the gear on the starter shaft with the ring gear of the flywheel. At the same time, the contacts of the traction relay close, and voltage is supplied to the armature and stator windings of the starter. In table 3 shows typical malfunctions of the above components and the reasons for their occurrence.

Table 3. Typical faults engine starting systems and the causes of their occurrence

Fuse blocks The fuses are located in the relay and fuse boxes located in engine compartment and inside the car (Fig. 2, 3).

Rice. 2. Location of the fuse box in the engine compartment

Rice. 3. Location of the fuse box in the car interior

The fuse housings are marked with rated current. When replacing a fuse with another, use a fuse of the same rating. On the inside of the fuse box covers there are graphic symbols indicating which fuse belongs to a particular circuit. The circuits protected by fuses and their nominal values ​​are given in Table. 4. Connection of various vehicle electrical systems, such as lighting, ignition, light signaling, instrumentation, etc. carried out using wiring harnesses with connectors. Lighting The vehicle lighting system includes the following elements: - headlights, side lights with direction indicators, headlight adjustment unit (these elements are structurally combined into front headlights); — Front anti-fog headlights; — rear block lights, which include fog lights, brake and reverse lights, turn indicator lights; — interior lighting. The lighting systems are controlled using multifunction switches located on the steering column. Possible faults lighting systems are often associated with failure of lamps and fuses. When replacing faulty lamps, it is necessary to install lamps of the same power (specified in the vehicle's operating manual). In the event of malfunctions related to the vehicle lighting, a warning lamp lights up in the instrument cluster. In modern modifications of the car, simultaneously with the warning lamp, a message appears on the multifunction display informing about a malfunction of one of the lighting devices. The instrument cluster and warning lamps also include a multifunction display that displays the following information: - a message about upcoming maintenance(MOT) of the car (remaining mileage until the next MOT, calculated day and month of inclusion warning lamp); — trip computer information ( total mileage, average speed, gasoline consumption, etc.);

— settings menu; — message about malfunctions; — date, current time, outside temperature, mileage (total, daily); — information during diagnostics. Fault messages displayed on the multifunction display are accompanied by an audible sound and an indicator light in the instrument cluster. Multiport fuel injection system Let's look at the design, operating principle and diagnostics of the distributed fuel injection system in Fiat Albea cars. These cars use a distributed injection system that meets Euro-3 toxicity standards.

Rice. 4. Simplified electrical diagram distributed fuel injection systems of the Fiat Albea car under Euro-3 toxicity standards model range 2008

In Fig. Figure 4 shows a simplified electrical diagram of the distributed fuel injection system of the Fiat Albea car under Euro-3 toxicity standards of the 2008 model series, with electronically controlled throttle valve. The distributed injection system is controlled by electronic unit control unit (ECU). It controls the fuel supply, ignition timing, idle speed, operation of the engine cooling system, the air conditioning compressor clutch and generates the necessary signals for the trip computer. In addition, the ECU ensures the required air-fuel mixture ratio in the engine combustion chamber. The ECU also exchanges information with the standard alarm system (immobilizer) to prohibit unauthorized engine starting. The car's distributed fuel injection system uses sensors that record general characteristics of one or another node, with further sending of a signal to the ECU. Different types of sensors are used: potentiometric (resistive), electromagnetic, piezoelectric and others. To reduce toxicity exhaust gases In the engine management system of a car, a catalytic converter (catalyst) is installed in the exhaust pipe; it is designed to reduce the content of harmful chemicals in exhaust gases: carbon monoxide, hydrocarbons and nitrogen oxides.

Rice. 5. Catalyst design and sensor installation locations

In Fig. Figure 5 shows the catalyst structure and sensor installation locations. Structurally, it consists of thin metal case, as a rule, made of stainless steel and a ceramic porous grid (honeycomb), the walls of which are coated with platinum group metals (platinum, palladium, rhodium).

An oxygen sensor (lambda probe) is installed directly in the exhaust pipe in front of the catalytic converter, and a diagnostic sensor is installed after the converter. Using these sensors, the ECU monitors the efficiency of the converter and regulates the parameters of the air-fuel mixture. The operation of the distributed fuel injection system of a Fiat Albia car is in many ways similar to the operation of the distributed fuel injection system of cars of the VAZ-11183 Lada Kalina and VAZ-2170 Lada Priora family. The on-board diagnostic system constantly monitors the condition and operation of the catalytic converter while the engine is running; in the event of failures or malfunctions, the computer turns on the malfunction indicator lamp located on the instrument panel. Malfunctions of the catalytic converter can be caused by several reasons: - misfire in one or more cylinders due to the fault of the mechanical part of the engine, malfunction of the injectors, ignition system; - use of low-quality fuel. At normal operation The entire engine control system has a service life of about 100,000 km.

Diagnostics of the distributed injection system, troubleshooting Diagnostics of the distributed fuel injection system of Fiat Albea cars is performed in the following sequence: - error codes are read from the ECU memory; — erase error codes from the ECU memory; - check engine operation; - troubleshoot problems. To carry out diagnostics, you can use a specialized portable diagnostic tester or personal computer, equipped with specialized software. The tester or computer is connected to the diagnostic connector located in the relay and fuse box in the vehicle interior. In Fig. Figure 6 shows a general view of a diagnostic device implemented on a laptop.

Checking the components of the distributed injection system Checking and identifying malfunctions of the components of the distributed injection system begins with monitoring the voltage at the battery terminals at running engine, it should be within 13.8...14.2 V. During testing and troubleshooting, turn off all additional equipment(lighting, the radiator fan of the cooling system should not be running, if the car is equipped with air conditioning, it should also be turned off, the car's built-in music equipment, etc. should be turned off). After this, the fault error codes are read, searched and eliminated. Below are examples of failures and error codes of some components of the vehicle's distributed injection system.

Air pressure/temperature sensor (error codes P0105-P0108, P0110-P0113) This combined unit consists of a pressure sensor and a temperature sensor. It is installed directly in the air flow in front of the throttle pipe. The pressure sensor is a barometric type, it measures the difference between atmospheric pressure and the pressure in the intake manifold. The sensor has a linear characteristic of the dependence of the output voltage (0.4....4.5 V) on the measured pressure (0.025....0.100 mPa). Based on sensor readings, the ECU estimates the load on the engine and adjusts the ignition timing. The air temperature in the intake pipe is recorded by a temperature sensor. This sensor is a resistive type, its resistance changes depending on the air temperature - at low temperatures the sensor has a high resistance. The air temperature sensor readings are used by the ECU to set the ignition timing. Structurally, the temperature sensor is built into the pressure sensor housing. If the barometric part of the sensor malfunctions, the ECU sets the standard pressure value.

Coolant temperature sensor (error codes P0115-P0118) This sensor is installed in the cooling system pipe; the sensor housing is located directly in the engine coolant flow. The sensor is a thermistor. The ECU calculates the temperature based on the voltage drop across the sensor, high level voltage corresponds to a cold engine, and low voltage corresponds to a warm engine. The sensor is checked using an ohmmeter, while the connector from the sensor is disconnected. The sensor resistance should be within 0.5...1.5 kOhm. Throttle position sensor (error codes P0120-P0123) This sensor is a potentiometric type, it is installed on the throttle pipe body and is mechanically connected to the throttle valve axis of the pipe. The sensor resistance changes depending on the throttle valve opening angle. The manifestation of a sensor malfunction can be different: unstable engine operation at idle, failure to increase engine speed when pressing the accelerator pedal, etc. If the throttle position sensor fails, the ECU registers an error code and automatically sets the nominal engine speed in order to to ensure the vehicle moves to the nearest service station. Oxygen sensor (error codes P0130-P0135) and diagnostic oxygen sensor (error codes P0136-P0141) The oxygen sensor contains a sensitive element capable of generating a voltage in the range of 55...980 mV depending on the oxygen content in the exhaust gases and the temperature of the sensitive element. To quickly warm up the sensitive element of the sensor after starting the engine and reaching the set temperature, the sensor includes a heating element, which is controlled by the ECU. Nominal operating temperature oxygen sensor is ZOSGS. The catalyst housing is covered with a protective screen made of aluminum alloys, this design solution was made to retain heat transfer and fire safety. During operation of the oxygen sensor, its output voltage varies from low (85...250 mV) to high (680...950 mV). Low level voltage corresponds to a lean mixture (the presence of oxygen in the exhaust gases), and a high level corresponds to a rich mixture (low oxygen content). The output voltage of the diagnostic oxygen sensor on a working converter should be within 600...800 mV. The first signs of a faulty oxygen sensor may be an increase in fuel consumption and deterioration in vehicle dynamics, possibly unstable work engine at idle speed. Crankshaft position sensor (error codes P0335 - P0344) The crankshaft position sensor is an electromagnetic type, it is installed on the camshaft drive cover at a distance of 1±0.5mm from the top of the crankshaft pulley teeth.

The crankshaft pulley has 58 teeth arranged around its circumference. When the crankshaft rotates, the teeth of the disk change the magnetic field of the sensor, creating pulses that are not supplied by the computer. Sensor failures are often associated with an increase in the gap between the sensor and the tops of the pulley teeth or with a failure of the sensor itself. Fuel supply system malfunctions The fuel supply system includes an electric fuel pump, a fuel rail assembly with four injectors, a fuel pressure regulator, and a fuel filter. The operation of the electric fuel pump and injectors is controlled by the ECU. The turbine-type electric fuel pump contains a fuel level sensor. Fuel supply system error code P0185-P0193. The injector ramp is a hollow bar with injectors and a pressure regulator installed on it. The injectors are installed with one side in the ramp and the other in the holes of the intake pipe; the tightness of the connections is ensured by O-rings. The nozzle design is solenoid valve, controlled by a signal from the ECU. Through this valve, fuel is injected under pressure into the intake pipe. Error code for injectors P0200-P0214.

When diagnosing the fuel supply system, be sure to check the integrity of fuses No. 4 and 6 located in the relay and fuse box of the engine compartment.

Of course, every car driver has his own goals, plans, tastes in choice and purchases. future car, and nowadays you can often see such a subcompact sedan as the Fiat Albea on domestic roads. Everyone probably knows why and for what they buy this car. But what weaknesses, sores and shortcomings the Fiat Albea has are described below.

• Clutch release bearing;
• Rear engine mounts;
• Rear springs;
• Steering rods;
• Wheel bearings.

Now more details...

Clutch release bearing.

On average, the bearing life is 50 thousand km. A sign of a dying bearing is increased noise when you press the clutch pedal. Therefore, when purchasing, it is imperative to pay attention to the performance of the clutch as a whole, both when starting off and when shifting into a higher gear while driving.

Rear engine mounts.

It is not easy to check the condition of the engine mounts yourself. When purchasing, you must first make a test run and make sure there is no vibration. As a rule, vibration can be felt not only in the car itself, but also in the steering wheel. Replacement in the future will not cost much.

Rear springs.

Rear springs are one of the sores of the Fiat Albea. With regular loads on the rear springs, they sag quite quickly. Therefore, when purchasing, you need to pay attention to this and generally check the integrity of the springs.

Steering rods.

As for the steering, it’s not paradoxical weak point is neither steering rack or tie rod ends (although often tie rod ends), and the tie rods themselves. Main external signs wear of steering rods is caused by large free play of the steering wheel and knocking noises when the steering wheel is rotated to the sides. Although replacing steering rods is not a very expensive operation, it is worth knowing about it and, even more so, it will not be difficult to check.

Wheel bearings.

Wheel bearings, as on all cars, can be classified as consumables, but it is on Albea that wheel bearings most often require replacement. Characteristic symptoms of a malfunction wheel bearing, as on other cars, there is a characteristic hum when driving.

The main disadvantages of the Fiat Albea

1. "Crickets" in the cabin;
2. Very poor sound insulation;
3. Cheap and low-quality upholstery;
4. Low engine power;
5. Problem finding spare parts;
6. Satisfactory review;
7. Original spare parts are expensive.

Conclusion.

In conclusion, we can say that Fiat Albea does not have any distinctive features in relation to its competitors of other brands and models. It is important to remember that if you decide to purchase of this car it is necessary to take into account all factors and risks, and before purchasing, carefully inspect and check the performance of all systems and components of this car, in addition to those indicated above.

Hello!!! While operating the car, problems arose, namely, 3 studs on the exhaust manifold broke, I went to a car service center, where they told me that I needed to remove the cylinder head to replace the studs and what spare parts I needed to buy. I bought the spare parts and handed them over to the service employees (there was no delivery acceptance certificate), the employees accepted the spare parts without warning me about the possible poor quality of these parts (the spare parts were non-original). A week later, all the repair work was done, a work order was drawn up with the work performed and a cash receipt; the spare parts I purchased were not mentioned in the work order. I picked up the car, paid in full for the work done, drove about 1000 km in 4 days, I found traces of oil in the engine cooling system, immediately called the car service center and explained the problem, the service staff told me to deliver the car to them to find out the causes of the problem. The service employees re-removed the cylinder head and determined that the fault was a non-original gasket, they said that you need to buy original spare parts namely, the cylinder head gasket and cylinder head mounting bolts, and that I will again have to pay for the removal and installation of the cylinder head and, accordingly, spare parts at my own expense. I demanded that they draw up an inspection report vehicle on their letterhead, an act was drawn up, it stated that the service employees found faults, and the reason was a poor-quality cylinder head gasket, established according to such an order (I have it in my hands), the act was signed by members of the commission (service employees) and car service seal. That is, the car service itself carried out an examination, so to speak, and established that the cause of the malfunction was a poor-quality cylinder head gasket, which they installed according to such and such an order along with it, but nowhere in any documents is it mentioned that I bought the gasket and handed it over to them. In general, I re-bought the original gasket myself, handed it over to the service with the drawing up of a transfer acceptance certificate, which states that the Customer handed over the cylinder head gasket to the Contractor (car service) to eliminate the malfunction during the work performed on such and such an order, the service master signed this certificate and delivered seal. The car service purchased the cylinder head mounting bolts itself. Now the car has been in the service queue for repairs for 10 days, and the service has everything necessary for repairs, they say that while they were waiting for the gasket from me, they accepted many cars for repairs. I don’t dare file a claim for poor-quality work now, because I’m afraid that the service might do something bad to the car. I called auto experts about conducting an independent examination. They say that an examination is impossible, since the cylinder head has already been removed. But the car service center removed the cylinder head again without my consent and without placing a work order. I independently filed a complaint with the car service so that they would fix the faults free of charge, after which they refused to finish the car at all. They offer to reimburse me for the cost of removing and installing the cylinder head (excluding spare parts, materials, moral damages) and make me a car with their own efforts. But I’m afraid to take the car to another service, because after the work done, other faults, and more significant ones, could appear. My question to you is what to do in such a situation? I don’t really want to go to court, because I’m afraid that the court will not be on my side, and I’ll lose a lot of time.
