Combustion in Direct Injection Diesel in Comparison with Controlled Combustion Stratified Charge Engines

Controlled combustion in direct injection stratified charge engines can be achieved by the use of impinging jets for injection as well as for ignition, in association with a close-loop, electronic control system. Upon the description of the method of approach required for the design of a control strategy, illustrated by application to a conventional diesel engine, salient features of novel concepts for direct injection stratified charge engines are presented.
