What is detonation in si engine? Detonation is spontaneous combustion inside the cylinder AFTER the spark plug fires. … This causes a steady increase in cylinder pressure and forces the piston down on the Power Stroke. When detonation happens, some of the air/fuel ignites before the normal burn can get to it.
What is meant by detonation in SI engine? Knocking (also knock, detonation, spark knock, pinging or pinking) in spark ignition internal combustion engines occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but one or more pockets of air/fuel mixture explode …
What is detonation and knocking in SI engine? “Knocking” and “detonation” are the interchangeable terms refers to the phenomenon of uncontrolled combustion in the IC engine. “Knock” is the sharp metal pinging sound produced in the engine due to uneven combustion. … In general, detonation is the cause and knocking is the after effect.
What is detonation What are the effects of detonation? What are the Harmful Effects Of Detonation In Engine ? 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 autoignite.
