Influences of the pre-chamber orifices on the combustion behavior in a constant volume chamber simulating pre-chamber type medium-speed gas engines

Combustion Engines, 2022
The study aims to clarify the influence of pre-chamber (PC) configurations on the combustion process in the main chamber (MC) of medium-speed spark-ignition gas engines equipped with an active PC. A constant volume combustion chamber was prepared to simulate the chamber configurations of the gas engines.

Extensive validation of a combustion and pollutant emission model of a pre-chamber engine including different pre-chamber geometries

Fuel
In this work, a 0D/1D model of a single-cylinder pre-chamber spark ignition (PCSI) engine is extensively validated with experimental data in terms of performance, combustion, and emissions by varying the pre-chamber geometry and operating conditions. In the first stage, an experimental study is carried out on the PCSI engine at 1600 rpm and wide-open ...
