Combustion Characteristics in a Constant Volume Combustion Chamber with Sub-Chamber (II) Effect of Combustion Promotion with Configuration Change of the Critical Passagehole

부실식 정적연소실내 연소특성에 관한 연구 (II) 임계연락공의 형상변화에 따른 연소촉진효과

To construct the design back data for a lean-burn gas engine, we investigated the combustion characteristics in the main chamber using a constant volume combustion chamber with subchamber. The combustion characteristics with configuration change of the critical passageholes have been studied by taking pressure data, schlieren photograph, ion current and light emission signal of flame. Heat release rate with various critical passageholes also have been analysed by using the combustion model of a prechamber diesel engine. It was found that combustion characteristics in the main combustion chamber were greatly influenced by the geometric configurations of critical passagehole.
