| Abstract: | In this paper, a spark ignition natural gas engine simulation based on 6134 Diesel Engine is carried out by using the software AVL-BOOST. The simulation describes the thermodynamic process of the engine and it proves to be reliable by the bench test. According to this, the paper analyzes the influence of the valve system on natural gas engine performance. The valve timing and cam profile have been optimized by the model. The optimal design is proved to meet the requirements of the bench test. The design finally improves the engine volumetric efficiency and reduces the engine exhaust temperature. |
