The knocking in diesel engines may be prevented by

The knocking in diesel engines may be prevented by Correct Answer All of these

The knocking in diesel engines may be prevented by- Arrange the fuel injector in such a way that it should start injecting only a small quantity of fuel in starting of the engine.-If we increase the injection pressure, which encourages the atomization of fuel and prevent knock.-by raising the temperature of the coolant that of the intake air as well as the cylinder head and combustion chamber.- Also by increasing the inlet pressure of air (Supercharging), we can prevent diesel knock.
