具有升程异步开启及相位可变功能的连续可变气门升程机构的设计
|
摘要
基于某型汽油机开发一种机械式具有升程异步开启及相位可变功能的连续可变气门升程机构,在控制转角0~201°范围内,可实现进气门升程可在0.3~8.6 mm的范围内连续可调,气门开启持续期在100~210°之间变化,气门升程由大升程至小升程调节时,可实现升程工作相位相应提前0~54°。通过设计气门升程调整机构,对差异不符合要求的气门升程进行调整,保证了生产时所有气门升程的一致性控制在±3%以内。
A mechanical continuously variable valve lift( CVVL) mechanism with lift desynchronized opening and variable phasing function was developed based on a certain gasoline engine. While the angle is controlled within 0 ~ 201°,continuously varying of intake valve lift can be realized within 0. 3 ~ 8. 6 mm,valve opening duration will vary in the range of 100 ~ 210°. When valve lift changes from long-move to short-move,the timing of the corresponding lift can be advanced accordingly by 0 ~ 54°. The variable valve lift design can adjust unacceptable valve lifting,ensure the lifting consistency of all valves during manufacturing,which is controlled within ± 3%. The CVVL mechanism design achieves its request.
