单缸柴油机废气涡轮增压试验研究

Research and Experimental Studies on The Exhaust Gas Turbocharging of The Single Cylinder Diesel Engine

废气涡轮增压作为提高发动机功率的主要技术广泛应用于车辆、工程机械等多缸汽、柴油机上,在提高发动机升功率、节能减排等方面效果显著。受限于生产成本、单缸柴油机结构等因素,国内外关于单缸柴油机涡轮增压的研究较少。为研究在单缸柴油机上运用涡轮增压提高发动机功率的技术可行性,进行了单缸柴油机涡轮增压试验。试验结果表明,单缸柴油机涡轮增压可大幅提高发动机的功率,发动机最低燃油消耗率略优于增压前的油耗,通过对发动机的进排气系统与燃油系统的优化,可望进一步提高柴油机的性能。

The exhaust gas turbocharging, as the primary technology used to increase engine power,is widely used in vehicles,engineering machinery,such as multi-cylinder gasoline and diesel engine.It has remarkable effect in increasing engine power,energy conservation and emissions reduction.The single-cylinder diesel engine turbocharging test results show that the single cylinder turbocharged diesel engine can substantially increase the power of engine and the engine minimum fuel consumption rate is a little better than before. It is expected to further improve the performance of the diesel engine through optimizing the inlet and exhaust system of engine and fuel system.
