摘　　要：根据CNG/柴油双燃料发动机对天然气的要求,即喷气驱动能定时准确地喷出天然气。以Peak&Hold电流波形为基础,基于英飞凌公司TC1728开发板中的GPTA模块以及DAVE、IDE、UDE3款编程软件,在某型号柴油机改装成的双燃料发动机上进行带电流反馈的天然气电控系统的开发,并在发动机台架上进行天然气喷气驱动的试验验证。试验结果表明该天然气喷气驱动程序控制波形比较稳定,喷气轨电磁阀能迅速地开启和关闭,电磁阀从完全关闭到完全开启,时间为600μs,Peak阶段电流能达到3A,Hold阶段电流维持在1A,满足了CNG/柴油双燃料发动机对于喷气驱动的要求。CNG/diesel dual fuel engine requires accurate jet ejection timing of jet driven for natural gas.Based on Peak Hold current waveform, via GPTA modules on Infineon＇s TC1728 development boards and DAVE, IDE and UDE programming software, a current feedback NG electric control system was developed on a dual-fuel engine converted from a diesel engine. Experimental verification of natural gas powered jet engine was carried out on bench. The test results show that the gas jet driver control waveform is relatively stable, jet-rail solenoid valve can be quickly opened and closed, the time of solenoid valve from fully closed to fully open is 600 μs, Peak phase current can reach 3A, Hold phase current is maintained at 1A, thus meet the requirements of CNG / diesel dual fuel engine for the jet-driven.
