A better design for the exhaust pipes adds to the efficiency, along with modified timing and pistons.
而优化设计的排气管和改进的计时器和活塞也有助于提高效率。
The timing of the rotary valve, which is a key operating parameter for cryocoolers, determines the relationship between the intake and exhaust process.
而平面旋转阀的时序又是低温制冷机的一个重要参数，它决定了制冷机系统进气、排气过程之间的相互关系。
Schemes of variable compression ratio (VCR), variable exhaust gas recirculation (EGR), variable exhaust valve timing, and EGR with stratification by tumble charge flow are recommended.
推荐可变压缩比（VCR）方案、可变废气再循环率（EGR）方案、可变排气门关闭时刻方案，以及废气再循环滚流分层充气方案等。
But because of reduced injection timing and increased exhaust back pressure, the BSFC of the engine will be increased of 8%.
但由于提前角减小，排气背压增大，发动机燃油消耗率上升8%左右。
The application results show that laser welding can meet higher strength stress demands for those fatigue load parts, such as intake and exhaust valves, timing gear, suspension equipment.
应用结果表明：对于进排气门、正时齿轮和悬架装置等承担疲劳载荷的零部件，激光焊接可满足其较高的强度要求；
The oil is fed to the CAM shaft, the intake-side CVVT device, the exhaust-side CVVT device and a timing chain tensioner at one time.
油被同时供至凸轮轴、进气侧CVVT装置、排气侧CVVT装置和正时链条张紧装置。
Experimental results show that the position of the converter nearer to the exhaust port, the retard ignition timing and the higher idle speed can promote the catalytic converter light-off.
试验结果表明，催化转化器的位置距排气口近可提高排气温度，大大提高催化转化器的转化效率；推迟点火提前角和提高怠速转速均有利于使催化转化器进入快速起燃状态。
