火花点火機関燃焼室内混合気濃度分布の二次元計測 : 燃料噴射および吸気条件の影響

概要

An experimental study was made of the two-dimensional measurements of the mixture concentration distributions in the combustion chamber of a propane-fueled SI (spark ingnition) engine with laser-sheet-induced Rayleigh scattering. A commercial engine was modified to introduce YAG laser sheet light into the combustion chamber. The scattered light from the measuring plane was allowed to transmit the optical glass window installed on the extended piston and captured with a charge-coupled-device camera fitted with a gated double-microchannel-plate image intensifier by lens coupling, and the resulting images were digitized in a computer. The effects of several engine-operating parameters, including the fuel injection conditions and the intake air flow, were investigated.
