Influence of Cam Profile on CNG Engine Performance and Emissions
In this paper, through numerical calculation and experiment, the cam phase was redesigned and the influence of cam phase on engine performance and emissions has been studied. At first, several cam phases were designed basing on original CNG(Compressed Natural Gas) engine using numerical software and two optimizations about valve phase were selected. Then the test bench of engine was made with different cam including optimized cams and the original one. By comparing the test experiment, it is found that the optimization No.3 whose valve overlap is 11° CA is the best one which considers both the power and the consumption of CNG besides reducing the exhaust gas.
