摘要： An internal combustion engine controller (2) that drives an electromagnetic load (5; 103) is provided for improving a fault diagnosis precision of the electromagnetic load (5; 103) and stabilizing a high-speed control without influence of noises (113) even if the drive cycle of the electromagnetic load (5; 103) is short. The internal combustion engine controller (2) has high reliability in a fault diagnosis for a circuit to regenerate counter electromotive energy. The internal combustion engine controller (2) comprises a current source (17, 19, 21) or a voltage source for controlling a potential of the diagnosis position in order to ensure a high-precision fault diagnosis even if the drive cycle of the electromagnetic load (5; 103), such as the fuel injector, in the internal combustion engine is shortened. Diagnosis timing is optimally set or the number of determinations for averaging is increased in order to ensure the high-precision fault diagnosis without being influenced by unexpected disturbance such as noises (113). In the fault diagnosis of the regeneration circuits into the booster circuit (3), an input/output voltage or the regeneration current of a driving switching element of the electromagnetic load (5; 103) is detected.

摘要： An internal combustion engine controller comprises a booster coil 110 connected to a battery 1 and a booster capacitor 130. A switch element 120 is connected to the booster coil 110 to control the passage of current through the booster coil 110 and an interruption of the current. The booster capacitor 130 accumulates electrical energy generated with an inductance of the booster coil 110 at the time of the interruption of the passage of the current. A booster control circuit 150 carries out control in a constant boost switching cycle 500 so as to pass the current through the booster coil 110 and the switch element 120 until the current reaches a preset switching stop threshold value 410 and then interrupt the current to charge the energy generated with the inductance of the booster coil 110 into the booster capacitor 130. The booster control circuit 150 is configured to ensure a minimum time period for the booster capacitor-charging of the energy within the boost switching cycle 500.

摘要： Disclosed herein is a fuel injection control apparatus for an internal combustion engine, capable of opening and closing accurately a valve of the fuel injector 5 even when the quantity of injection required is small and a pulse duration of a driving pulse signal to the fuel injector 5 is short.
A fuel injector pulse width computing unit 9a calculates, from the operational state of the internal combustion engine and the fuel pressure detected by a fuel pressure sensor 26, pulse width of a pulse signal which drives the valve of the fuel injector 5. After an valve-opening command has turned on and a high valve-opening current for opening the fuel injector valve has been supplied from a high-voltage source to the fuel injector 5, a fuel injector driving signal waveform command unit 9b discharges the current and supplies from a low-voltage source a small hold current Ih2 that allows the fuel injector 5 to maintain the valve-open state. Also, during the time from supply of the valve-opening current to an arrival at the value of the hold current Ih2, after the elapse of a previously assigned rapid-discharge starting time Tsy from the turn-on of the valve-opening command, the fuel injector driving signal waveform command unit 9b rapidly discharges the current until the hold current Ih2 has been reached.
