摘要： PROBLEM TO BE SOLVED: To provide a pilot-ignition type gas engine provided with a scavenging device for an auxiliary combustion chamber by which scavenging of the auxiliary combustion chamber can be surely achieved by preventing generation of malfunction and thermal-fatigue failure, due to heat of the auxiliary combustion chamber, while attaining simplification of the structure, reduction in the number of component-count, and cost-reduction. SOLUTION: In the pilot-ignition type gas engine, a scavenging path is provided for supplying to the auxiliary combustion chamber a part of charging air in the charging path which is branched from the charging path to communicate with the auxiliary combustion chamber, and a check valve is provided in the scavenging path in order to allow the charging-air flow directing from the charging path to the auxiliary combustion chamber, and shut off the gas directing from the auxiliary combustion chamber to the charging path. Thus, scavenging of the auxiliary combustion chamber is carried out by a part of the charging air that is passed through the scavenging path. COPYRIGHT: (C)2006,JPO&NCIPI
