Further improved engine intake stratifier for continuously variable stratified mixtures

摘要

Means for creating continuously variable stratified air fuel mixtures at the intake of an internal combustion engine are described wherein the air fuel ratio and/or the kinds of fuel molecules vary through the mixture. Compression ignition delay gradients can be created by use of these continuously variable stratified mixtures and in consequence a gradual occurrence of compression ignition can be achieved with great reduction of engine noise and improvements in engine utilization efficiency.
