INC 33265 Precombustion Chamber
INC 33265 Precombustion Chamber

An item specifically designed to be used as an auxiliary chamber in which combustible gases are ignited and combustion started ahead of the main combustion chamber of a diesel engine. It may have provisions for a glow plug or a wick to ignite the fuel mixture during cold weather starting.

Additional Information for Precombustion Chamber Additional Information for Precombustion Chamber

A precombustion chamber, also known as a prechamber or a swirl chamber, is a component found in some diesel engines. It is part of the combustion system and is designed to improve the combustion process in the engine.

In a diesel engine, fuel is injected into the precombustion chamber, which is a small chamber located within the main combustion chamber. The precombustion chamber is connected to the main combustion chamber through small passages or orifices.

When fuel is injected into the precombustion chamber, it mixes with a small amount of air that is already present in the chamber. This mixture is then ignited by the heat and pressure generated by the main combustion process. The ignited mixture then rapidly expands and flows into the main combustion chamber, where it further ignites the air-fuel mixture in the cylinder.

The precombustion chamber serves several purposes in a diesel engine. Firstly, it helps to promote better fuel atomization and mixing, which leads to more efficient combustion. This can result in improved fuel economy and reduced emissions.

Secondly, the precombustion chamber helps to reduce the noise and vibration associated with diesel engines. By providing a controlled and separate combustion process, it helps to dampen the pressure waves and reduce the overall noise level.

Lastly, the precombustion chamber can also improve the engine's cold-start performance. By providing a smaller volume for combustion, it allows for faster and more efficient ignition, even in cold conditions.

Overall, the precombustion chamber is an important component in diesel engines, particularly in older designs. However, with advancements in fuel injection technology, newer diesel engines may use other methods, such as direct injection, to achieve similar combustion efficiency and emissions control.
