3. Install the 5M2667 Gasket, with “2C” on it, on the precombustion chamber. 4. Install the precombustion chamber 2018-01-05 · A small prechamber near the combustion chamber is filled with a small amount of an auxiliary fuel-air mixture immediately before ignition, then, considering the high chemical activity of the products of incomplete combustion from a rich prechamber, occurs an fast, stable and complete combustion in main chamber. The term indirect injection refers to a fuel injection system where fuel is not directly injected into the combustion chamber. An indirect injection diesel engine delivers fuel into a chamber off the combustion chamber, called a pre-combustion chamber, where combustion begins and then spreads into the main combustion chamber. A new pre-chamber ignition system The MAHLE Jet Ignition® system is a new combustion technology which replaces the standard spark plug in SI engines with a jet ignition pre-chamber assembly, without requiring a separate ignitior within the main combustion chamber.

The Pre-Combustion Chambers in diesel engines suffer extreme changes in their structures, and with time they tend to crack, they sink below the engine's head's surface, and they also get loose. Due to constant air-fuel combustion's they wear, and sometimes they crack, and if they are not change they can damage the engine's block surface. concept for a pre-chamber ignition system operating with fuel rich pre-chamber combustion strategy as a very e ective alternative ignition system for heavy duty natural gas engines. The studies also contribute to the fundamental knowledge and understanding of the mechanism of pre-chamber ignition.
