What is the difference between knocking and detonation?
Knocking is a rattling noise caused by abnormal combustion in the engine, typically due to improper fuel octane or ignition timing. Detonation is a more severe form of knocking where the air-fuel mixture explodes rather than burns, leading to increased pressure and temperature that can damage the engine. Both can be harmful to the engine and should be addressed promptly.
Is detonation caused by low octane fuel?
Yes, detonation can be caused by low octane fuel. Octane rating measures a fuel's resistance to knocking or detonation, which occurs when fuel-air mixtures ignite prematurely in the engine. Using fuel with a lower octane rating than what the engine is designed for can lead to increased engine temperatures and pressures, resulting in knocking and potential engine damage. To prevent detonation, it's important to use fuel that meets the manufacturer's recommended octane rating.
What is the difference between combustion and detonation as in a internal combustion?
When the engine detonates its referring to the engine giving spark to the compressed air/fuel in the cylinder, when theres combustion its simply the explosion that happens after ignition.
What is the detonation and knocking in cars?
When an engine runs as it should the fuel/air mix in the combustion chamber ignites at the spark plug and the flame front spreads from there. In an engine that's knocking there are hotspots in the combustion chamber causing the fuel/air mixture to ignite prematurely a bit all over the place.
Why knocking produce in engine?
Knocking in an engine, often referred to as "detonation," occurs when fuel-air mixture ignites prematurely in the combustion chamber, causing a rapid pressure spike. This can be due to various factors, such as low-quality fuel, incorrect ignition timing, or excessive engine temperatures. The resulting noise can indicate potential damage to engine components if not addressed, as it leads to increased wear and tear. Proper tuning and using the right fuel can help mitigate knocking.
What causes engine knocking when going up a hill?
Engine knocking when going up a hill is often caused by a combination of factors, primarily related to improper fuel combustion. This can occur due to low octane fuel, which leads to pre-ignition or detonation, where the air-fuel mixture ignites prematurely. Additionally, factors like insufficient engine cooling, improper ignition timing, or excessive load on the engine can exacerbate the issue. Maintaining proper fuel quality and ensuring the engine is well-tuned can help mitigate knocking.
What is the difference between preignition and detonation and how do they cause engine damage?
They are the same thing. They cause damage by applying the force of combustion to the piston before it has reached the top of its stroke, which basically pushes it "backwards"

A have a Toyota Tercel and it running but it got a knock on the engine now what could be the problem?
A knocking sound in your Toyota Tercel's engine could indicate several issues, such as low oil levels, worn bearings, or detonation (knocking) due to poor fuel quality. It may also be a sign of engine wear or damage, such as a failing piston or connecting rod. It's important to check the oil level and quality first, and if the knocking persists, have a mechanic diagnose the problem to prevent further damage.
Why is diesel is not used in petrol engines?
Because diesel is ignited of heat and high high compresion not a spark on lower compresion petrol engine. If you use diesel in a petrol you will end up with your engine knocking and pre-detonation followed by your engine blowing up pretty bad.
