在正常工况下,以图15所表示的喷油量供给发动机所发出的扭矩、输出功率、比油耗和烟色特性等示于图18。图中的实线表示以柴油机作燃料,虚线表示烧汽油的结果。输出功率和扭矩曲线在1500转/分到2500转/分转速范围内是令人满意的,扭矩增加约为18％,相当于最大扭矩1340牛顿·米。如已经解释的那样,为了保证用户提出的烟色限制低于3个波许值,在发动机转速低于1500转/分时,应减小喷油量。 Under normal conditions, the torque, the output power, the specific fuel consumption, the smoke color characteristics, and the like, which are supplied to the engine with the fuel injection amount shown in FIG. 15, are shown in FIG. 18. The solid line in the figure shows the diesel engine as a fuel, and the broken line shows the result of burning gasoline. The output power and torque curves are satisfactory at 1500 rpm to 2500 rpm with a torque increase of about 18%, corresponding to a maximum torque of 1340 Nm. As already explained, in order to ensure that the user’s limit of smoke color is less than 3 baud values, the fuel injection amount should be reduced when the engine speed is lower than 1500 rpm.
