single cylinder naturally aspirated engine (CNG) on engine performance based on high-speed high load comparison with baseline conditions early ignition late ignition and rich and lean PV graph and p theta comparison how to do with results (already obtained) comparing emissions, MFB ( 10 % 50% 90%).......Analysis if it's more or less the values how to analyze the basic comparisons for eg baseline vs high speed vs high load if the values are more why is it?

rich and lean comparisons what happens AT TDC early and late ignition ...what happens to the parameter change
