Passage 1（原题库第1篇）Valve drive mechanismThe valve drive mechanism commands the inlet and exhaust valves at the required timing.第3题The valve drive mechanism consists of an inlet and exhaust cam follower (8) each suspended in a plunger of the tappet assembly (7), two tubular push rods (4) with ball joints, two nodular cast iron rocker arms (2) suspended in a rocker arm bearing bracket, two yokes (5) and a yoke guide pins. See Fig. 4-1.The tappet rollers follow the cam profiles and transfer the movements through push rods to the rocker arms.第4题The rocker arms operate the inlet and exhaust valves through yokes (5).Lubrication for the rocker arms comes from the engine's secondary oil supply manifold throughdrillings in the cylinder head and rocker arm bracket.第2题The tappet assembly receives lubricating oil via channels in the engine block from the main supply manifold. For the roller and shaft, the oil is supplied through the guiding plunger.第4题To compensate for heat expansion a clearance must exist between the rocker arm and yoke.第1题All adjustments have to be done on a cold engine only.1. According to the Passage, the best time to adjust the valve clearance is _____.A. before the engine is startedB. when the engine is runningC. after the engine has just been stoppedD. when something has gone wrong with the engine注：根据文章来看，调节阀间隙的最好时间是在发动机启动之前。
