| Abstract:Based on GT-POWER software, a certain type of 8.3L electronic control common rail diesel engine was studied focusing on the relationship between valve timing optimization design and engine fuel economy. According to analysis results, a new kind of camshaft was developed and trial-produced.The engine performance test with this new camshaft was done to validate the simulation results. The research showed that new camshaft with valve timing optimization design successfully improved engine fuel economy by 1.25% over full operating range. |
