Scavenged Pre-chamber Volume Effect on Gas Engine Performance and Emissions
Original language description
This work presents development and experimental investigation of advanced ignition system with scavenged pre-chamber for extremely lean mixture combustion in a natural gas fueled engine. The lean burn concept is used to reach low production of nitric oxides emissions (NOx). The influence of the scavenged pre-chamber volume on the combustion and engine performance is presented in this paper. Two pre-chambers with different volume (2,3 % and 4,9% of compression volume) were tested at steady state conditions on a gas-fueled engine with 102 mm bore and 120 mm stroke. The main effort was to solve the challenge with unburned hydrocarbons at extremely lean operation by increasing the pre-chamber volume and thus increase the ignition energy and improve the overall engine performance.
