Abstract:

The effects of the fuel supply per cycle and the exhaust gas recirculation(EGR) rate on the power output, the fuel economy and the exhaust emission behavior of the homogeneous charge compression ignition(HCCI) ethanol engine were investigated experimentally on a singlecylinder test engine modified from a conventional production ergine. The results show that the indicated thermal efficiency of the HCCI ethanol engine can reach as high as 60%, the peak indicated mean effective pressure Pmi is 0.6 MPa. The proper combination of the equivalent airfuel ratio a and the EGR rate can effectively control the autoignition timing of the HCCI combustion and thus the NOx emission level. However, the introduction of the EGR results in the increased HC and CO emission levels of the engine.

Key words: power machinery and engineering, ethanol engine, homogeneous charge compression ignition(HCCI) combustion, exhaust gas recirculation(EGR), exhaust emission
