Knocking to the internal combustion engine ( or striking to the piston) is one not ideal burning way. It will make the internal-combustion engine work violent, the power drop, the economy of the fuel become bad. 内燃机爆震(或敲缸)是一种不理想的燃烧方式,它会使内燃机工作粗爆,功率下降,燃油经济性变差。
The ignition-start and knocking characteristics of the combustion system were studied on a single cylinder test engine. 在单缸试验机上研究了这一燃烧系统的着火起动特性和敲缸现象。
By adopting late injection, combustion process can be well controlled, knocking combustion can be avoided under high methanol concentration and large load, and so engine load range can be further extended. 采用晚喷方式,燃烧过程能得到较好的控制,高甲醇浓度大负荷下不容易出现爆震燃烧,能进一步扩展发动机负荷工况范围。
