介绍一种用于双顶置凸轮轴式发动机的采用两级谐波传动的新型进气凸轮轴调相机构。
A new camshaft-phasing mechanism with twin harmonic drives is described and illustrated, which can be adopted to DOHC (double overhead camshaft) engines.
链条驱动机构包括一条双排辊链,通过它来驱动进气和排气凸轮轴。
The chain drive consists of a duplex roller chain which drives both intake and exhaust camshafts.
进气行程:凸轮轴打开进气阀,活塞在汽缸中向下运动,产生一段真空。
Intake stroke: the camshaft opens the intake valve and the piston moves down the cylinder. This creates vacuum and sucks in air and fuel into the combustion chamber above the piston.
另外,GM表示新引擎将是“同级之中其中一款最宁静及最精细引擎”,因为新引擎采用一个静音进气歧管盖及倒齿式凸轮轴链条。
Gm also says the mill will be "one of the quietest and most refined engines in the segment" because of an acoustic intake manifold cover and inverted-tooth camshaft chains.
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。
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.
