发动机气门间隙实用快速调整法的理论基础是(1)、需要调整的气门必须是关闭状态,也就是说凸轮的基圆与气门的挺杆或与摇臂或与气门脚相接触,这样的气门才能调整。(2)根据曲轴曲拐结构,只要是偶数气缸的,总有对应的气缸活塞同时到达上止点。当某一气缸处于压缩上止点时,则另一对应气缸处于排气终了上止点,(也就是进、排气门叠开时),这样处于气缸压缩的气门都可调整,在已知的发火次序中气缸压缩与排气终了(也就是进、排气门叠开时)气缸之间的气缸的排气门是可调的。在排气终了气缸以后的气缸进气门是可调的。
Engine valve clearance practical rapid adjustment method is based on the theory (1), the need to adjust the valve must be closed, that is to say the base circle of the cam and the valve tappet or with the rocker or contact with the valve foot, such valve Can be adjusted. (2) According to crankshaft crank structure, as long as it is even numbered cylinder, there are always corresponding cylinder pistons reaching top dead center at the same time. When a cylinder is in compression top dead center, then the other corresponding cylinder at the exhaust end of the top dead center (that is, into, exhaust valve stack open), so that the cylinder compression valve can be adjusted, known In the firing sequence, the cylinder’s exhaust valve is adjustable between the cylinder compression and the end of the exhaust (ie, when the intake and exhaust valves are open). The cylinder intake valve after the exhaust end cylinder is adjustable.
