Diesel Knock

It is very important that we should know at least some of the ideas about normal conditions, abnormal conditions and the knocking in diesel engines. If you don’t know about that, the article will give a clear idea about the normal, abnormal conditions and the knocking. If the delay period is long, a large amount of fuel will be injected and accumulated in the combustion chamber. The auto ignition of this large amount of fuel may cause high rate of pressure rise. This high pressure rise causes the heavy vibration of the engine and creates lot of noise. This phenomenon of combustion causing heavy pressure rise during uncontrolled combustion is known as “Diesel Knock”. Diesel knock generally starts at the very beginning of the combustion process due to sudden auto ignition of large amount of fuel.
