Highlights of Jetfire® Ignition Process

During Intake, purge air through the purge assembly efficiently replaces prechamber residuals from previous cycle with fresh air.

During mid-Compression, fuel is injected into the prechamber and fresh air-fuel mixture prepared for spark.

Combustion starts inside the pre-chamber prior to peak compression leading to the chemically active turbulent jets entering the main combustion chamber. 

Combustion starts inside the main chamber, leading to the flow being pushed into the pre-chamber.   

Expansion and Exhaust proceed & process starts again with the beginning of Intake.
