The cranked shaft does not rotate or rotates very slowly at start of the engine a starter:
– the accumulator is discharged; – unreliable connection of plugs of the accumulator; – damage of a starter.
The cranked shaft of the engine rotates, the engine is not started:
– there is no fuel; – chains of system of ignition are damaged; – hoses of fuel system are damaged; – hoses of system of ventilation of a case are not tight; – an air suction in an inlet collector.
The engine stops or works unstably at idling turns:
– hoses of system of ventilation of a case are not tight; – an air suction in an inlet collector; – poor fuel mix; – valvate gaps are incorrectly adjusted.
Unstable operation of the engine and weak dispersal:
– fuel mix is incorrectly adjusted; – the air filter is polluted; valvate gaps are incorrectly adjusted.
The raised oil consumption:
– piston rings or sleeves of cylinders are worn-out; – maslootrazhatelny caps are worn-out.
At operation of the engine there is an extraneous mechanical noise:
– valvate gaps are incorrectly adjusted; – o strong wear of the engine.
Foreign knocks at acceleration:
– low octane number of the used fuel; – engine overheat; – carbonaceous deposits in combustion chambers; – plentiful release of vapors of oil which gets to system of ventilation of a case of the engine. |
