介绍了电控LPG-柴油双燃料内燃机供给系统的设计,柴油分别采用机械泵和电磁铁执行器供给,LPG采用电控顺序喷射方式供给。同时对控制系统进行了硬件和软件设计,对软件的功能进行详细的说明,最后对双燃料内燃机进行标定试验,论证了柴油的电控喷射对降低烟度排放的影响。
The design of electronic LPG diesel dual fuel internal combustion engine supply system is introduced. Diesel fuel is supplied by mechanical pump and electromagnet actuator, respectively. LPG is supplied by electronic controlled sequential injection. At the same time, the hardware and software design of the control system is carried out. The function of the software is described in detail. Finally, the calibration test of the dual-fuel internal combustion engine is carried out to demonstrate the effect of diesel fuel electronically controlled injection on reducing smoke emission.
