10.喷油泵起动油量越多越好起动吗? 答:柴油机起动时转速低,喷油器喷雾质量较差,加之柴油机机温及压缩终了时,气缸内压力较低,而产生的可燃混合气过稀,不利于点火燃烧。针对这种情况,可适当地增加喷油泵的起动供油量,以增加可燃混合气的浓度,称为起动加浓。一般应比额定供油量高30%以上。但是,喷油泵起动油量过多,反而造成柴油机起动时混合气过浓,更不易起动,就是强行起动,燃烧后的瞬间,柴油机
A: The diesel engine starting speed is low, the injector spray quality is poor, combined with the diesel engine temperature and compression end, the cylinder pressure is low, and the resulting combustible mixture Excessive gas is not conducive to ignition and combustion. In view of this situation, may be appropriate to increase the fuel injection pump starting fuel supply to increase the concentration of combustible gas mixture, called start enrichment. Generally should be higher than the rated fuel supply more than 30%. However, the fuel pump starting oil too much, but caused when the diesel engine starting mixture is too thick, more difficult to start, is forced to start, the moment after combustion, the diesel engine
