▲  低燃油消耗量

电喷CNG发动机的ECU通过读取发动机的各种传感器信号来计算,并进行各种修正(燃气温度、压力、进气歧管压力、冷却液温度、瞬态响应和闭环控制修正等),进行精确的多点顺序喷射。保证各种发动机各种工况获得低燃油消耗量和低排放。

▲  可靠性好

电喷CNG发动机的ECU有带自学习功能,随着发动机长时间运转,发动机和系统会出现磨损,系统基本上无需调整(除了简单的减压器设置外)或特殊的维护,控制系统具备自适应控制策略(学习控制),保证性能。

▲  运转稳定

电喷CNG发动机采用多点顺序喷射,精确控制燃气喷射量,发动机运转稳定。电喷CNG发动机具有故障诊断接口,故障判断简单。发动机转速限制功能和电磁阀备自动断气(3秒)功能。当发动机转速超过系统设置最高转速,系统将自动断气,来限制发动机转速无限制上升,以保护发动机。

Low fuel consumption

       the ecu of efi cng engine gets the datas, then calculates and revises all the parameters, including gasfired temperature and pressure, suction pressure, coolant temperature, momentary response and closed loop control amendment. Precise multi-point sequential injection ensures all engines get low fuel consumpation and low emission in all conditions.

Good reliability

      the ecu of efi cng engine has self learning function. Along with the engine running, the system will be worn. No much adjustment or special maintenance is required, except simple pressure release device. The control system has

Self adapting ability to ensure the performance.

Stable operation

    efi cng engine adopts multi-point sequential injection, controls fuel injection volume precisely. The engine runs stable.malfunction judgement easy.

    efi cng engine has malfunction judgement connection. It is easy to find out the malfunction.

limitation on rotating speed of the engine and automatic cut-off function(3s) of solenoid valvewhen the rotating speed of the engine surpasses the highest set point, the system will cut off the gas automatically to prevent the speed from going up endless. Thus protects the engine.
