GENERAL INFORMATION

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.
