配气机构是发动机的动脉,如果尺寸结构和加工精度不够或保养不当,会使发动机功率不能正常发挥,油耗上升,并会产生高温、爆震、活塞烧顶、拉缸等等故障。我们在三级保养中,抽检了解放CA10C型汽车的梯形加速度凸轮轴,其中一根超差严重,检测结果如表1;现在按正确的配气相位(图1),以第六缸为例予以分析。 Valve body is the engine of the engine, if the size structure and processing accuracy is not enough or improper maintenance, the engine power will not be able to properly play, fuel consumption rise, and will produce high temperature, detonation, piston burning Top, cylinder and so on failure. In the third-level maintenance, we sampled the trapezoidal acceleration camshaft of the CA10C-type car, one of which had serious over-tolerance and the test results are shown in Table 1. Now, according to the correct valve phase (Figure 1) and the sixth cylinder Be analyzed.
