摘要
由发动机原理可知,在一定范围内增大压缩比,可以提高发动机有效热效率,合理设计配气相位角,可提高充气效率,进而达到提升发动机性能的目的。基于这一思想,本文对增大压缩比和改变配气相位角这两种方案在发动机性能优化过程中的应用进行探讨。
According to the principle of engine, the effective thermal efficiency and the volumetric efficiency can be improved through increasing compression ratio and changing valve timing angle respectively within limits so as to improve the performance optimization of engine. Based on the above, the application of increasing compression ratio and changing valve timing angle to improve the performance optimization of engine are studied in the thesis.
