我市广大农机人员,不断对柴油机进行节能技术改造和推广节能新技术,收到了很好的节能效果。现将几种节油技术介绍如下:一、油环槽倒角钻孔.在 S195型柴油机上,将二道活塞油环下沿都倒角20度,深为原油环槽的1/2。在二道油环槽倒角的斜边上钻φ3.5孔20个,排列为原孔相错;在第一道油环倒角的斜边上钻φ3.5孔10个.这样增加了回油能力,基本上克服了机油窜烧,降低油耗达40%左右.二、扩孔排气。在 S195型柴油机上,用钻头将阀座出气孔每隔一孔扩大一孔,原来孔径4毫米,扩大到6.5～8毫米;阀片若有装反的,重新正过来;已经丢失的,要再
The majority of agricultural workers in our city, continue to carry out energy-saving diesel engine technical transformation and promotion of new technologies, received a very good energy-saving effect. Now several fuel-saving technologies are introduced as follows: First, oil ring groove chamfering drilling In the S195 diesel engine, the two piston rings are chamfered along the bottom 20 degrees deep for the crude oil ring groove 1/2. In the second oil ring groove chamfering hypotenuse drilling φ3.5 hole 20, arranged for the original hole phase error; in the first oil ring chamfering hypotenuse drilling φ3.5 holes 10. This increase Back to the oil capacity, basically to overcome the oil channeling, reducing fuel consumption up to 40%. In the S195 diesel engine, the seat hole with a drill to expand a hole every other hole, the original hole diameter of 4 mm, expanded to 6.5 to 8 mm; if fitted with anti-valve, to come back over; have been lost to again
