Torque and power of CNGDI engine with two different piston crown shapes

This paper presents the experimental test results of single cylinder high compression engine fuelled with compressed natural gas. The engine uses central direct injection with high pressure injector system which is known as Compressed Natural Gas Direct Injection (CNGDI)engine. This initial experime...
