A Precombustion Chamber is a component found in some diesel engines' cylinder heads, Its purpose is to enhance the combustion process by promoting better fuel atomization and increasing the mixture's air-fuel mixing efficiency.Attributes: • Preventing overheating and potential damage to the chamber.• Reduced noise.Applications: A Precombustion Chamber is commonly found in indirect injection diesel engines. In these engines, fuel is injected into the precombustion chamber, which is connected to the main combustion chamber.
