在云贵高原上使用车用发动机,由于地理条件、海拔高度不同,往往达不到设计者的要求。也就是功率不能充分发挥出来。广大的驾驶员和修理人员在使用和维修中总结出一些行之有效的方法,这些方法,不但能使高原上所使用的发动机的功率损失得到一定的弥补,而且在理论上有一定的参考价值。现将两点改进介绍如下: In the Yunnan-Guizhou Plateau using car engines, due to geographical conditions, altitude is different, often fail to meet the requirements of designers. That is, the power can not be fully exerted. The majority of pilots and repairers in the use and maintenance of summed up some effective methods, these methods not only make the plateau on the use of the engine power loss to be a certain make up, but also in theory have some reference value . Now two improvements introduced as follows:
