Research and Development of a Direct Injection Stratified Charge Rotary Engine with a Pilot Flame Ignition System 2001-01-1844

A Direct Injection Stratified Charge Rotary Engine ( DISC-RE ) with a pilot flame ignition system has been studied to find the possibility of simultaneous reductions of fuel consumption rate and HC exhaust gas emissions. Firstly, combustion characteristics in a model combustion chamber, which simulates the DISC-RE were examined from the viewpoints of calculation and experiment. The high speed photography and the indicated pressure analysis were experimentally performed while numerical calculations of the mixture formation and combustion processes were also carried out. As a result, it has been found that the combustion using the pilot flame ignition system is much activated and a better ignitability is attained under lean mixtures than using a spark ignition system. Secondly, a single rotor with 650 cc displacement DISC-RE was built as a prototype. Combustion characteristics and its performance were tested using a combustion analyzer. Light oil and kerosene were used for performance tests. As a result, the DISC-RE showed capabilities of practical use. Also, this engine could be stably operated using multi-fuel such as gasoline, light oil, or kerosene.
