A METHOD OF CHARGE STRATIFICATION FOR FOUR-STROKE-CYCLE SPARK-IGNITION ENGINES 580127
With the advent of automotive engines having very high horsepower capacities, the problem of part-load economy has become serious. One method of improving the efficiency of the spark-ignition engine at light load is the use of mixture-ratio control to effect load variations. Charge stratification makes this method of load-control possible. In this paper the principles involved in stratification are discussed, and a new method for producing stratification is described. The results of engine tests using this method are presented to show the method is workable, and that the predicted advantages actually are obtained.
“…there is little doubt that, sooner or later, the system of working with a stratified charge will become commercial, … it is possible and the high efficiency theoretically obtainable from it can be approached.” (1)*
