Summary:

A Direct Injection Stratified Charge Rotary Engine (DISC-RE) with a pilot flame ignition system which has high ignition energy, large flame contact area and long duration of ignition source, has been examined comparing with a spark ignition system, using a model combustion chamber simulating a DISC-RE. As a result, it was found that the combustion using the pilot flame ignition system was activated and that a better ignitability was attained under lean mixture conditions than using a spark ignition system. To analyze these experimental results, numerical calculations of the mixture formation and combustion process were carried out. Numerical analyses proved that the pilot flame ignition system was superior to the spark ignition system as the pilot flame ignition made large-area ignition source and large inflammable mixture region. Finally, a single rotor with 650 cc displacement DISC-RE was built as a prototype. Basic running tests of this engine under light load conditions were performed. Test results showed that capabilities of practical use with a higher thermal efficiency than conventional rotary engines
