GENERAL INFORMATION

At engine start the crankshaft does not rotate:

– accumulator plugs are unreliably connected or oxidized;
– the accumulator is discharged or faulty;
– violation of integrity of electroconducting in a starter chain;
– the traction relay of a starter is faulty;
– the starter is faulty;
– teeths of a gear wheel of a drive of a starter or teeths of a gear wreath – a flywheel are worn-out;
– the tire of grounding of the engine on the car case is disconnected.

The crankshaft rotates, but the engine is not started:

– there is no fuel in a tank;
– the accumulator (the crankshaft rotates very slowly) is discharged;
– are unreliably fixed or oxidized the accumulator plug;
– elements of system of ignition (petrol engines) are damaged;
– the wrong gap in spark plugs (petrol engines);
– the system of prestarting heating (diesel engines) is faulty;
– damage of system of injection of fuel (petrol engines);

– a low compression in cylinders.

Unstable start of the hot engine:

– the filtering element of the air filter is polluted;
– damage of system of injection of fuel (petrol engines);
– a low compression in cylinders.

At inclusion of a starter there are extraneous noise:

– teeths on a gear wheel of a starter or a gear wreath of a flywheel are worn-out or broken;
– bolts of fastening of a starter are absent or are unreliably tightened;
– wear or damage of details of a starter.

Engine stop after start:

– unreliable connection of elements of system of ignition (petrol engines);
– подсос air in system of injection or an inlet collector (petrol engines);
– damage of system of injection of fuel (petrol engines).

Unstable power setting idling:

– the filtering element of the air filter is polluted;
– подсос air in injection system, an inlet collector or hoses (petrol engines);
– the interelectrode gap is incorrectly adjusted or spark plugs (petrol engines) are worn-out;
– a non-uniform or low compression in cylinders;
– cam-shaft cams are worn-out;
– the gear belt of a drive of the mechanism of a gazoraspredeleniye is incorrectly established;
– damage of system of injection of fuel (petrol engines);
– nozzles (diesel engines) are faulty.

Ignition admissions idling:

– the interelectrode gap is incorrectly adjusted or spark plugs (petrol engines) are worn-out;
– defective high-voltage wires (petrol engines);
– подсос air in injection system, an inlet collector or hoses (petrol engines);
– damage of system of injection of fuel (petrol engines);
– nozzles (diesel engines) are faulty;
– a non-uniform or low compression in cylinders;
– hoses of ventilation of a case of the engine were disconnected or are not tight.

Ignition admissions in all range of turns of the engine:

– the fuel filter is polluted;
– it is faulty or low pressure of supply of fuel the fuel pump;
– the drainage opening of a fuel tank or топливопроводы is hammered;
– подсос air in injection system, an inlet collector or hoses (petrol engines);
– the interelectrode gap is incorrectly adjusted or spark plugs (petrol engines) are worn-out;
– the ignition coil (petrol engines) is faulty;
– the nozzle (diesel engines) is faulty;
– the cover of the breaker of the distributor (petrol engines) is faulty;
– a non-uniform or low compression in cylinders;
– damage of system of injection of fuel (petrol engines).

Engine vibration at acceleration:

– the interelectrode gap is incorrectly adjusted or spark plugs (petrol engines) are worn-out;
– подсос air in injection system, an inlet collector or hoses (petrol engines);
– damage of system of injection of fuel (petrol engines);
– the nozzle (diesel engines) is faulty.

Unstable operation of the engine:

– подсос air in injection system, an inlet collector or hoses (petrol engines);
– the fuel filter is hammered;
– malfunction or low pressure of supply of fuel fuel pump (petrol engines);
– the drainage opening of a fuel tank or топливопроводы is hammered;
– damage of system of injection of fuel (petrol engines);
– nozzles (diesel engines) are faulty.

Low return of engine capacity:


– the gear belt of a drive is incorrectly established;
– the fuel filter is hammered;
– it is faulty or low pressure of supply of fuel the fuel pump;
– a non-uniform or low compression in cylinders;
– the interelectrode gap is incorrectly adjusted or spark plugs (petrol engines) are worn-out;
– подсос air in injection system, an inlet collector or hoses (petrol engines);
– the system of injection of fuel (petrol engines) is faulty;
– nozzles (diesel engines) are faulty;
– the moment of injection of fuel of the fuel pump (diesel engines) is incorrectly established;
– jamming of brakes;
– coupling pro-slipping.

Return flashes in the engine:

– the gear belt of a drive of the mechanism of a gazoraspredeleniye is incorrectly established;
– подсос air in injection system, an inlet collector or hoses (petrol engines);
– damage of system of injection of fuel (petrol engines).

Low pressure of oil in the engine:

– low level of oil or its wrong grade;
– the sensor of pressure of oil is faulty;
– bearings of the engine or the oil pump are worn-out;
– engine overheat;
– the safety valve of pressure of oil is faulty;
– the mesh filter of a maslopriyemnik is polluted.

The engine works after ignition switching off:

– an excessive deposit in combustion chambers;
– engine overheat;
– damage of system of injection of fuel (petrol engines);
– the electromagnetic valve of a stop of the engine (diesel engines) is faulty.

Noise in the engine

Detonation in the engine at acceleration:
