OMT公司最近研制成功一种用于直喷式高速和中速柴油机的可变流量喷油嘴并且获得了专利。这种新型喷油器的特点是只有高压油管与喷油泵相连接，没有回油管。伸进燃烧室部分的喷油器体由一套筒组成，喷油循环期间柱塞在其中做往复运动。杜塞顶端周围沿螺旋线和径向制有油道孔。喷 OMT recently developed and patented a variable flow injector for direct injection high-speed and medium-speed diesel engines. The new injector features a high pressure hose connected to the fuel pump without a return pipe. The fuel injector body which extends into the combustion chamber section consists of a sleeve in which the plunger reciprocates during the injection cycle. Dusay around the top of the helical and radial system made of oil hole. spray
