基于GT-Power的柴油机改CNG发动机对比研究
Comparative Study of Diesel Change CNG Engine Based on GT-Power
摘要
Abstract
In order to improve urban air quality,Guangzhou is preparing to converted into compressed natural gas fuel buses. This paper established CNG single fuel a diesel engine model with GT-Power. Simulate its performance. The simulation uses a four-stroke single-cylinder diesel engine 407cc. compared to the original diesel engine by external characteristics,The results showed that the brake power,brake torque,brake specific fuel consumption,volumetric efficiency has decreased significantly,through the study pointed out that the conversion of natural gas engine power reasons for the decline. And to restore natural gas engine power draw method pointed out the direction for further research,and also provides a theoretical support for the implementation of CNG fuel engine .关键词
