Gasoline Volvo Dice Vida engine knock reasons

Gasoline engine knock phenomenon, but the  Volvo Dice Vida  causes of what is it? Analysis knocking phenomenon, to understand its causes, and according to the crux of the problem to be resolved.

The combustible mixture of gasoline engine start is ignited by the high pressure. Then, the combustion flame spark plug center spread, a mixed gas of the combustion chamber is ignited, such combustion process as a normal combustion. If the flame does not arrive before the rest of the mixed gas is not ignited on the self-ignition, and this combustion called knocking.

The knock is not allowed to occur in the normal operation of the engine, it will lead to increased wear and tear of the parts of the engine block and shorten the life of even rapidly destroyed, but also the engine power down, increases fuel consumption.

Produce detonation phenomena:

, Knock cylinder sudden shock waves, shock   Volvo dice vida 2011A to all sides, engine piston, cylinder walls, connecting rod, crankshaft, strong vibration, irregular metal percussion;

2, cooling system temperature is too high;

3, incomplete fuel   Autel MaxiDAS DS708  combustion, there is black smoke in the exhaust gas;

4, decreased engine power, fuel consumption increases.

Solution:

1, reducing the ignition advance angle;

2, using the provisions consistent grade (octane) gasoline;

3, removal of the combustion chamber coke;
