近来在汽车运输方面有这种意见,认为节约燃料只是由使用的方法来达到目的的。如正确地调整点火提前角(柴油机的供油提前角),正确调整燃料装置,驾驶汽车的合理方法等等,而几乎不注意节约燃料的潜力,如汽车,特别是发动机合理的修理。这里应该理解为狭义的修理,即应该从取得零件正确的几何尺寸的观点来理解,因为这些尺寸严重影响着发动机的经济性。到目前为止,在大部分汽车修理厂中,曲轴各拐之间角度位置的修复工作并没有在工艺上规定下来,甚至曲轴的最大扭曲度超过允许的扭曲度达11倍(见《AT》,1977,
There has been such a suggestion recently in the field of motor transport that saving fuel is achieved only by the methods used. Such as correctly adjusting the ignition advance angle (diesel fuel supply advance), proper adjustment of the fueling device, the proper method of driving a car, etc. with little regard for the potential for fuel savings, such as the rational repair of vehicles, especially the engines. It should be understood here as a narrow repair, which should be understood from the point of view of obtaining the correct geometry of the part, as these dimensions seriously affect the economy of the engine. To date, the repair of the angular position between the crankshafts has not been technically defined in most auto repair shops, and even the crankshaft has a maximum twist of more than 11 times the allowable twist (see “AT”, 1977,
