Consider Your Cooling System..

Is detonation bad for an engine?

But prolonged heavy detonation is bad news because it hammers the pistons and rings. If the problem is not corrected, severe detonation may damage your engine. It can crack pistons and rings, cause the head gasket to fail, damage spark plugs and valves, and even flatten rod bearings.

How do you check for detonation in an engine?

Moderate to severe detonation could be noticed as engine roughness, vibration or loss of power and eventually engine damage. A pilot should always be looking for unexpectedly high Cylinder Head Temperatures (CHTs) or Exhaust Gas Temperatures (EGTs) which may be a sign that detonation is occurring.

What does detonation feel like?

When detonation happens, some of the air/fuel ignites before the normal burn can get to it. This causes a brief, but intense, spike in cylinder pressure. Detonation is also called an “Engine Knock”, “Knocking”, or “Pinging” because of the sound it makes.

What is difference between knocking and detonation?

Knocking is the making sharp sounds due to uneven combustion of fuel in the cylinder of a vehicle engine. Detonation is the process of pre-ignition or auto-ignition of a fuel in an engine’s combustion chamber.

What is detonation and what causes it?

Answer: Detonation, or engine knock, occurs simply when fuel pre-ignites before the piston reaches scheduled spark ignition. … Detonation is generally caused by excessive heat, excessive cylinder pressure, improper ignition timing, inadequate fuel octane or a combination of these.
