Abstract

PURPOSE:To prevent both stop of a fuel pump and rapid change of a fuel supply quantity to an internal combustion engine, by providing a control switching delay circuit between a fuel pump driving current control circuit and a control release circuit. CONSTITUTION:A fuel pump driving current control circuit 1, fuel pump driver circuit 2, fuel pump 3 and fuel pump driving current detector circuit 4 are connected in a loop state. A control switching delay circuit 5 consists of a capacitor charge-discharge circuit 6 and transistor emitter follower 7 to perform delay switching operation of the fuel pump driving current control circuit 1. In this way, at transfer from a control release state to a controlled state, a stop of the fuel pump can be prevented. Further a delivery quantity of fuel from the fuel pump is gradually changed, and stable driveability of an internal combustion engine can be obtained.
