12. The basic malfunctions

12.1. The engine
THE GENERAL DATA

At engine start коленвал does not rotate:

– 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 starter inclusion 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;
– Deterioration or damage of details of a starter.

Stop of the engine 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 backlash 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 timing is incorrectly established;
– Damage of system of injection of fuel (petrol engines);
– Atomizers (diesel engines) are faulty.

Ignition admissions idling:

– The interelectrode backlash 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);
– Atomizers (diesel engines) are faulty;
– A non-uniform or low compression in cylinders;
– Were disconnected or негерметичны ventilation hoses картера the engine.

Ignition admissions in all range of turns of the engine:

– The fuel filter is polluted;
– It is faulty or low pressure of giving of fuel the fuel pump;
– The drainage aperture of a fuel tank or топливопроводы is hammered;
подсос air in injection system, an inlet collector or hoses (petrol engines);
– The interelectrode backlash is incorrectly adjusted or spark plugs (petrol engines) are worn out;
– The ignition coil (petrol engines) is faulty;
– The atomizer (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 backlash 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 atomizer (diesel engines) is faulty.

Unstable work 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 giving of fuel the fuel pump (petrol engines);
– The drainage aperture of a fuel tank or топливопроводы is hammered;
– Damage of system of injection of fuel (petrol engines);
– Atomizers (diesel engines) are faulty.

Low return of capacity of the engine:


– The gear belt of a drive is incorrectly established;
– The fuel filter is hammered;
– It is faulty or low pressure of giving of fuel the fuel pump;
– A non-uniform or low compression in cylinders;
– The interelectrode backlash 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;
– Atomizers (diesel engines) are faulty;
– The moment of injection of fuel of the fuel pump (diesel engines) is incorrectly established;
– Jamming of brakes;
– Coupling proslipping.

Return flashes in the engine:

– The gear belt of a drive of the mechanism timing 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 gauge of pressure of oil is faulty;
– Bearings of the engine or the oil pump are worn out;
– An engine overheat;
– The safety valve of pressure of oil is faulty;
– The mesh filter маслоприемника is polluted.

The engine works after ignition deenergizing:

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