What is the detonation and knocking?
Detonation is the spontaneous combustion of the end-gas (remaining fuel/air mixture) in the chamber. It always occurs after normal combustion is initiated by the spark plug. Pre-ignition is defined as the ignition of the mixture prior to the spark plug firing
What is the purpose of a knock sensor on 2002 Mercury Villager?
It detects detonation in the combustion chamber(s), then adjusts the engine timing to compensate.
Detonation of petrol engines?
Detonation is a misused word. Pre-ignition is the common problem which cause mis-timing of the combustion cycle. Pre-ignition occurs from a combination of high heat ignition source, temperature and lean ratio mixes. Detonation has two main features, a) poor combustion design that causes a clash of two flame fronts within the combustion chamber that causes two shock waves to hit each other and creates a destructive force. b) a correct combustion chamber that allows the ultra lean fuel mix to explode omni-direction and consumes all the fuel mixture and then extinguishes itself and thus renders no harm to the engine with the expanding gas as the work loan and the contracting gas as a cooling gas at the end of the cycle. A petrol engine with the correct combustion chamber can run on compression ratios of 20:1 and lean petrol mixes as a detonation engine. The real future of the petrol engine is yet to be produced with extraordinary milage and low pollutants. SCB
What does the intake valve do?
Intake valve allows the atomized fuel mixture to enter the combustion chamber to be ignited by spark plug creating detonation
What is another word for combustion?
Burning, detonation for supersonic combustion and deflagration for subsonic combustion.
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.
What causes 305 motor to smoke?
The Piston rings are probably worn causing oil to get into the combustion chamber which causes smoke when burned
How many general types of combustion chambers are used in diesel engines?
Diesel Engine combustion chamber types : Swirl port combustion chamber type and Preignition port combustion chamber type.
Why there is detonation at start of combustion in SI engines?
china hope my answer is good
What is combustion chamber?
something
What is the difference between detonation and knocking in ic engine?
Detonation involves a supersonic exothermic. Knocking in a engine is spark-ignition internal combustion.
What is the reason for having a combustion chamber on a rocket?
A combustion chamber is where combustion occurs in a controlled fashion. Because the basic idea of a rocket is burning fuels and directing them in the opposite direction to that of travel, a controlled burning - as happens in the combustion chamber - is exactly what a rocket needs to work.
