本文对柴油机喷油过程中的出油阀校正问题进行了多方案的试验研究,探讨了出油阀校正的机理和出油阀校正对喷油过程的影响。指出了采用出油阀校正的限制因素是柴油机的低速烟度和机械加工工艺水平,采用合适的出油阀结构型式可放宽对机械加工精度的要求,使成批生产成为可能。 This paper conducts a multi-plan experimental study on the calibration of the delivery valve in the process of diesel engine injection, discusses the mechanism of the delivery valve calibration and the influence of the delivery valve calibration on the injection process. It is pointed out that the limiting factor of the valve calibration is the low speed smoke degree of the diesel engine and the machining process level. The appropriate valve structure can relax the machining precision requirements and make the batch production possible.
