HEM4000 ENGINE CONTROLLER is used for controlling engine to realize engine auto start/stop, data measuring, alarm protection and “three remotes” (remote control, remote measuring and remote communication) functions. It provides speed regulation function, not only with relay speed-adjusting output but also with GOV interface, which can control all kinds of non-EFI engines’ speed.
HEM4000 ENGINE CONTROLLER adopts large liquid crystal display (LCD) and selectable Chinese and English interface with easy and reliable operation. Users can read engine working parameters from the LCD directly. 
HEM4000 ENGINE CONTROLLER uses 32 bits ARM micro-processor technology with the functions of precise parameters measuring, fixed value adjustment, time setting and threshold adjusting etc. The majority of parameters can be set on the front panel and all the parameters can be set and monitored via USB port or RS485 port by using PC. With compact structure, simple connections and high reliability, it can be widely used in a number of engine control systems, which include water pump system, beacon system, air compressor, engineering machinery system and so on
