对柴油机二级喷射柱塞副的结构进一步改进 ,以改善柱塞的速度特性 ,减小柱塞的漏油面积。在标定油量不变的情况下增大起动油量 ,以改善二级喷射柴油机的起动性能。还设想出二级喷射柱塞副应具备的结构 ,以适应不同机型、不同工况下柴油机二级喷射的油量分配及时间间隔 ,以便更好地发挥二级喷射柴油机的优越性
The structure of the secondary injection plunger of diesel engine is further improved to improve the speed characteristics of the plunger and reduce the oil leakage area of the plunger. In the case of the same nominal fuel increase the amount of starting oil to improve the starting performance of two injection diesel engine. Also contemplated secondary injection plunger should have the structure to meet the different models, under different operating conditions of the two-stage injection of diesel fuel distribution and time interval in order to better play the advantages of two-stage injection diesel engine
