What is Pre Combustion Chamber on Diesel Engines?

A pre-combustion chamber is a small chamber located within the main combustion chamber of a diesel engine. It is designed to improve the combustion process by enhancing fuel efficiency, reducing emissions, and improving engine performance. The pre-combustion chamber is typically a small cavity or chamber that is connected to the main combustion chamber through small orifices or passages. It is usually located near the fuel injector nozzle. The purpose of this chamber is to facilitate the ignition of the air-fuel mixture and promote efficient combustion. The pre-combustion chamber serves several important purposes in diesel engines, such as reducing the ignition delay, achieving better fuel atomization, promoting turbulence generation, and influencing the combustion characteristics of the diesel engine.
