Internal combustion engine controller

Abstract

Abstract PURPOSE:To make a proper value securable at all driving areas by adjusting a nozzle area and fuel injection timing according to a loaded condition in an engine. CONSTITUTION:Fuel charge and engine speed detected by detectors 8, 9 are inputted into a computer 100, and a current brake mean effective pressure at running time is calculated at an engine loaded condition computing element 103. Then, a nozzle area and a desired value of injection timing to a combination of this brake mean effective pressure and the engine speed are stored in a memory 106. Next, setters 104, 105 draw respective desired values from the memory 106 and set each of them. Subsequently, the desired value compensated at compensators 107, 108 is outputted to a nozzle area adjuster 4 and a fuel injection timing adjuster 5, altering the nozzle area of a supercharger 2 and the injection timing of a fuel injection pump 3. In addition, these compensators 107, 108 calculates a deviation between the desired value and a current value outputted out of detectors 6, 7, and according to it, each output signal for the adjusters 4, 5 is adjusted.
