Abstract：The simulation model of a 16V190 gas engine is built based on simulation software AVL BOOST. Under a full-load condition at rated speed, simulation analysis and calculation are done respectively for different valve timing angles, comparing these parameters of manifold temperature,gas consumption rate, peak fire pressure, power and others. This researchprovided the basis for determining a reasonable distribution of valve timing and improving engine performance.
