Abstract

Abstract: Natural gas is the main substitute fuel of vehicle engine, not only at present, but also in the future. While air-fuel ratio is the important adjustable parameter influencing the performance of CNG (Compressed Natural Gas) vehicle engine. In this paper, the air-fuel ratio of CNG vehicle engine is optimized by using the method of computer simulation & analysis, and engine performance is improved

Key words: natural gas engine, air-fuel ratio, simulation, optimization

摘要： 天然气是现在以及未来汽车发动机的主要替代燃料。而空燃比是影响天然气汽车发动机性能的重要调整参数。本文用计算机仿真分析手段对天然气汽车发动机的空燃比进行了优化，改善了发动机的性能。
