Embodiment Construction
[0028] The present invention realizes based on the ECU of electric control engine, and ECU (Electronic Control Unit, electronic control unit) is also called "driving computer", "vehicle computer" etc. Computing, processing, judging, and then outputting instructions to provide an electrical pulse signal of a certain width to the injector to control the fuel injection volume. At present, cars equipped with electronically controlled engines are equipped with CAN meters, which can display the instantaneous fuel consumption rate and total fuel consumption of the engine in the current state, but the driver cannot know the state of the engine's fuel economy in the current state.
[0029] The core of the present invention is to provide a method for displaying the fuel economy state of an automobile engine. In order to control the movement of the whole vehicle reasonably, make the vehicle engine work in the economical fuel consumption zone, give full play to the efficiency of the engin...
