compression knock 双语例句
This paper describes the improvement of the combustion chamber of CA6102vehicle engine. Tests on a single-cylinder test engine show that, when MON70 gasoline is burnt, the new combustion chamber gives a higher combustion rate and better anti-knock ability. Thusa higher compression ratio and leaner mixture can be used, resulting in better fuel economy andhigher power output. Since no change in the manufacturing equipment is needed, the improvedcombustion chamber can be easily utilized.
在单缸试验机上对CA6102型汽油机燃烧室的改进试验结果表明：该燃烧室在燃用MON70汽油时具有较强的抗爆能力和较高的燃烧速率，利于采用较高压缩比和燃用稀薄混合气，改善了发动机的燃油经济性和动力性，且生产时无须更改原有加工设备，便于推广应用。
In the process of metal forming, the material of blank will be extruded into the die cavity to obtain various geometries. Due to the effects of friction and elastic deformation, it`s necessary to knock out formed work-piece by high ejector force. For conventional stamping die, the way to push out the formed material is to utilize the recovery force of the ejector pin which is an elastic compression component. However, this way is not suitable for micro forming die, because the die hole is usually less than 1mm and the mechanism is difficult for machining and assembly within limited space.
金属成形制程中，胚料常常须挤压进入模穴，而形成各种形状尺寸；然而成形后受摩擦力及弹性变形的回复力影响，必需藉强力逼出成品，现行成形模具退料方式都是采用顶出梢利用弹性压缩元件的回复力，将成形后的成品推出模穴；但是在精微成形制程中，模穴大多在1.0mm以下的孔穴，其需要的顶出梢及弹簧都是很小不容易加工制作及组装，且模具空间不足。
To increase the compression ratio of gasoline engine is always limitted by the anti-knock characteristics of the fuel.
汽油机压缩比的提高受燃料抗爆性的限制。在汽油中添加适量醇燃料能提高燃料的抗爆性，因此可提高汽油机的压缩比，获得更好的动力经济性能。
Knock of acceleration process in 92 single-cylinder gaseline engine with compact high compression ratio combustion chamber and air/fuel ratio for dynamic transitions in 492Q gaseline engine with microcompuer controlled system were precisely controlled by respective designed controllers.
分别对92单缸机高压缩比紧凑型燃烧系统加速过程中的爆震和492Q汽油机动态空燃比进行了控制，设计了爆震控制器与油膜补偿控制器，取得了良好的控制效果。
