Abstract

Stratified mixture was formed in the constant volume bomb by the injection of gaseous fuel. The structure of the transient fuel jet was visualized by the laser tomography and the combustion characteristics of the stratified mixture was investigated. Combustion pressure and the amount of unburned fuel were affected strongly by the ignition timing. The unburned fuel was caused mainly by the bulk quenching in the over lean region. Secondary flame came out in the burned region after the initial flame had propagated through the fuel jet in the condition that the mixture was ignited during the fuel injection. The shape of this flame was quite different from that in the condition that the ignition timing was after the termination of the injection. Fuel rin the burned region and injected fuel after ignition burned gradually mixing with surrounding air.
