The Factors That effect the Spark Knock

The Factors That effect the Spark Knock Points : the factors that effect the spark knock, the factors that effect the detonation, problems in internal combustion engines, ic, engine, auto diesel Detonation (also called “spark knock”) is an erratic form of combustion that can cause head gasket failure as well as other engine damage. Detonation occurs when excessive heat and pressure in the combustion chamber cause the air/fuel mixture to auto-ignite. This produces multiple flame fronts within the combustion chamber instead of a single flame travel. When these multiple flames collide, they do so with explosive force that produces a sudden rise in cylinder pressure accompanied by a sharp metallic pinging or knocking noise. The hammer like shock waves created by detonation subject the head gasket, piston, rings, spark plug and rod bearings to severe overloading.
