天然气/柴油双燃料发动机电控喷气技术研究

Electronically Controlled Gas Injection of Natural Gas/Diesel Dual Fuel Engine

本文研制开发了天然气/柴油双燃料发动机的压缩天然气(CNG)电控喷气系统。试验表明,电控喷气可以明显改善双燃料发动机的燃料经济性和排放性能,提高发动机的热效率。合理选择喷射压力和喷射相位可有效地提高燃烧速度和燃烧稳定性。

In this paper, an electronically controlled natural gas injection system was successfully designed for a dual fuel engine. Experiments of the dual fuel engine with the injection system proved that the electronically controlled natural gas injection could improve the performance of dual fuel engines, especially in increasing combustion speed, fuel economy, the combustion stability and lowering emissions.
