What is Detonation in IC engine

Question

Accepted Answer

Detonation is an abnormal combustion process in an internal combustion engine where the air-fuel mixture explodes instead of burning smoothly.

Detonation occurs when the air-fuel mixture in the combustion chamber ignites spontaneously due to high pressure and temperature.
It results in a rapid and uncontrolled release of energy, causing a sharp increase in pressure and temperature.
Detonation can lead to engine knocking, increased wear and tear, and reduced engine efficiency.
It can be caused by factors like improper fuel-air mixture, high compression ratio, carbon deposits, or excessive engine temperature.
Detonation can be prevented or minimized by using higher octane fuels, optimizing engine design, and maintaining proper engine conditions.

Accepted Answer

What is meant by detonation in IC engine? Detonation is defined as a sudden explosive combustion process occurs due to the burning of end-gas (An unburnt that produces high-pressure waves and sound inside the cylinder.
