摘要
对天然气和柴油双燃料发动机的复合燃烧规律进行了研究 ,主要阐述负荷、转速、替代率、柴油供油特性、引燃油量、进气混合气浓度和供油提前角等因素对双燃料的耗热率、燃烧循环变动和爆震燃烧的影响。特别指出天然气、柴油双燃料燃烧经济性和稳定性的主要特点。
In this paper, through a series of experimental investigations the combustion characteristics of a dual fuel (natural gas/diesel) engine were performed. Based on the investigations, the influences of the load, speed, substitution ratio (natural gas for diesel), quantity of pilot diesel fuel, density of mixing gas (natural gas and air) and injection advance of pilot diesel fuel on the brake specific heat consumption, cyclic variation, combustion deterioration and knock were also studied. Especially, the features of the fuel economy and the combustion stability of a dual fuel engine were given and the existent problems as well as their approaches were discussed.
