Abstract:

A method for improving the part load economy of spark ignited gasoline engines was investigated. In this method a liquid spray is injected into a high velocity air swirl so as to have a part of the spray localize near a spark plug located in the center of the air swirl. In this way a smallAMOUNT OF FUEL CAN BE STRATIFIED NEAR THE SPARK PLUG TO FORM AN IGNITABLE MIXTURE. It was thus possible to ignite over-all lean fuel-air ratios. Research covers the investigations made with a swirl chamber designed to simulate as closely as possible, with auxiliary equipment, conditions in a gasoline engine prior to ignition. High speed photography of the spray dispersion and combustion in the swirl chamber, along with visible indication of combustion, were used to obtain most of the data. Author
