Abstract

The HCCI engine was evaluated using different optical techniques, including Raman, PLIF, and spectrally resolved chemiluminescence to investigate the combustion process involved in an HCCI engine. The experiments were conducted in a six-cylinder, truck-sized engine, with one modified cylinder for optical access. The engine was run at 1000 rpm under ultra-lean conditions. Unlike the diesel engine, the HCCI engine generated low NO_x emissions while keeping a low soot formation level. The HCCI engine has a higher efficiency at part load and less cycle-to-cycle variations than the spark-ignition engine. Essential differences were found among the different fuels used in the HCCI engine. Also, the flame development under HCCI conditions differed considerably from the Otto and Diesel combustion. The patterns in the OH- and fuel-distributions indicated that the charge starts to burn simultaneously at arbitrary points across the combustion chamber. Original is an abstract.
