Explain octane number and cetane number

WebThe octane number is the percentage by volume of iso-octane in the iso-octane–heptane mixture that matches the fuel being tested in a standard test engine. The octane number of a fuel is measured in a test engine against a mixture of iso-octane and heptane. If a gasoline sample has the same antiknock quality as that of a mixture containing 90 ... WebBack compression means the compression capability of the engine. An diesel engine can compress at the ratio of 14:1 to as high as 25:1. Thus the higher compression leads to better efficiency of the engine. Thick black smoke is emitted when the engine’s compression is reduced which leads to the deformed ead-gasket lead into crankcase.
