Currently , diesel engines with injection pump are still widely used for various services , so it is necessary to develop dual fuel retrofitting technology on the basis of natural gas as a clean -alter-native fuel.Electronic control unit is the core of dual -fuel diesel engine system .To meet the general requirements of retrofitting dual fuel diesel engine with injection pump , the electronic control unit is developed .After the main control chip is determined , the whole hardware circuits are designed into modules for main control system , processing analog signal , driving actuator and so on .Meanwhile , the control theory and method of natural gas injection timing are put forward base on the pressure variation signal of diesel injection .Finally , experiments on engine bench show that the electronic control unit developed in high feasibility and reliability is capable of handling sensor data and qualified for control -ling natural gas injector and stepper motor .
