美国研制出1.2 L铝制CIDI发动机。这种电喷、铝质、用双头螺栓装配的发动机(Diata),是一种多种燃料的清洁柴油机。 这种发动机采用了双头螺栓装配的新工艺,从而减少了零部件,降低了金属疲劳,而其独特的铸造气缸套增强了铝气缸壁。 该发动机采用复式凸轮,16气门4缸发动机的功率约54 kW。当与公用底盘上的直喷燃油系统连接时,Diata的热效率超过 40％,而其各项性能指标相当于当今的中型轿车发动机的水平。公用底盘燃料喷射系统可按不同的工作条件实行标准化。 由于其燃油喷射喷嘴位于气缸中心,所以能提高效率并减少污染排放。 [潘丽丽 供稿]
The United States developed a 1.2 L aluminum CIDI engine. This EFI, aluminum, stud-mounted engine (Diata) is a multi-fuel, clean diesel engine. This engine incorporates a new process for stud bolt assembly, reducing parts and metal fatigue, while its unique cast cylinder liner enhances the aluminum cylinder wall. The engine uses double cams, 16-valve four-cylinder engine power of about 54 kW. When connected to a direct injection fuel system on a common chassis, Diata’s thermal efficiency exceeds 40% and its performance is comparable to today’s midsize sedan engine. Common chassis fuel injection system can be standardized according to different working conditions. Because of its fuel injection nozzle is located in the center of the cylinder, it can improve efficiency and reduce pollution emissions. [Polaroid feed]
