The combustion and emission characteristics of a four cylinder engine fueled with LNG are analyzed. The influence of engine performance changes with
engine structure parameters and operating parameters is studied. Results show that ignition
timing increases properly can improve LNG engine in-cylinder combustion process, improve engine
power performance and economy performance, but NOx emission increases. The best dynamic
performance of LNG engine is near the theory of air-fuel ratio. Appropriate compression ratio can
improve the engine power performance and economic performance. The influence of compression ratio
does not have certain rule to NOx.
