A new method of fuel design to control HCCI combustion was given.n-heptane/iso-octane was controlled real-time on a single-cylinder HCCI combustion engine.The test result shows that the equivalence ratio of n-heptane in mixture decides the HCCI ignition and controls the combustion phase of HCCI.The addition of iso-octane extends the knocking limit in equivalence ratio somewhat,however the knock occurrence mainly depends on the total concentration of mixture.Although the operation range in equivalence ratio ...
