Diesel knock is generated due to fully advanced timing and retard conditions. If the timing is retard the fuel will not be burned purely and rapid pressure will be developed and pinking noise will be generated. In a advance condition the fuel is injected in to the combusion chamber before reaching the piston tdc the burning will start suddenly otherhand the piston is being compresses the charge. The combusion should be done at maximum pressure and temperature but in this case the fuel does not burnt at that stage (actually piston wants the load at that time)the pressure is not developing instanteniously rapid pressure developed thats why the diesel knock generates. Another reason for diesel knock if diesel does not have the good cetane number knocking will be generated

Who made first diesel engine?
Rudolf Diesel
How can calculate power of diesel Engine?
You will need to have some information ready. It is good to know the horsepower and the torque of your diesel engine.
Is a turbine a form of diesel engine?
No
What is intake stroke in a diesel engine?
In a gasoline engine, it is a fuel-air mixture that is drawn in during the intake stroke, unless the engine is fuel injected. In a fuel injected or a diesel engine, it is air, because the fuel (gasoline or diesel) is injected at the "last moment" before ignition.
What replaced the steam engine?
diesel and gasoline engines
What will happen when petrol is poured into a diesel engine?
The engine will knock.
Four stroke diesel engine work principle?
how diesel engine works. on which principle diesel engine works. who search the diesel engine. capacity of diesel engine. how we calculate the efficiency of diesel engine. firing order of diesel engine. any videos
Is diesel knock damaging?
The diesel knock is damaging because it will have a tremendous force on the main bearings and will cause excessive wear of the piston rings.
When did Rudoulph Diesel invent the diesel engine?
the diesel engine was invented in 1892 by Rudolf Diesel. the diesel engine was invented in 1892 by Rudolf Diesel.
What octane is diesel?
Diesel has an octane number of about 15-25. The reason for this seemingly terrible number compared to the ones we're used to from gasoline is the fact that diesel is combusted in a totally different type of engine. Diesel has low volatility, low knock resistance, yet high energy per volume. Because of its low knock resistance, diesel should not be used in a gasoline engine as it will destroy it very quickly and efficiently. Generally speaking, diesel fuel ignition quality is not measured in octanes, as these are a unit for gasoline. A similar reference value, but for diesel, is the cetane rating. The higher the cetane number, the easier the fuel ignites when injected into an engine. The cetane number is determined by an engine test using two reference fuel blends of known cetane numbers. The reference fuels are prepared by blending normal cetane (n-hexadecane), having a value of 100, with heptamethyl nonane, having a value of 15. The higher the cetane rating, the higher the fuel's propensity to knock! Choosing a very high cetane number will not make the car run better, but using a fuel with too low cetane number may prevent the engine from starting or running.
Why does Engine knock sensor come in after 2 hours of operation?
The reason is it might be failing due to the heat.
What is the best oil for diesel engine 2006 megane?
Any diesel engine should use any 15-40 weighted oil. Reason being is that because it is the heaviest and thickest engine oil and takes longer to break down due to incresed oil pressure experienced by a diesel engine.
Does the engine on a 2003 impala knock in the top of the motor if the knock sensor is bad?
The knock sensor just advances and retards the engine timing only. If there is a noise in the engine then you have engine are valve train problems. The knock sensor will not make the engine knock.
Different green diesel and diesel engine?
green engine is 6stroke engine and diesel engine is 4 stroke
How does a modern engine management with a knock control system react to engine knock?
This is controlled by a knock sensor.
Will there be any problem if gasoline was put in diesel run car engine?
Yes, if a sufficient quantity of gasoline went through it. Knock in the engine from detonation is going to be the main problem, which could ultimately render the engine useless.
Why does your engine knock?
