Abstract
A fuel injection apparatus which prevents delay of the pressurization of the fuel injected and deterioration of the starting characteristic at the time of engine cold starts and the resultant increase in emission of hydrocarbons by leading to an auxiliary startup pump the hydraulic pressure generated in the hydraulic cylinders supporting the driver's seat when the driver gets in the car and sits on the seat before startup, converts this to a high fuel pressure by large and small diameter cylinders, and obtains a fuel spray with a good atomization by a high fuel pressure immediately after startup. Other forces which can be used are the force generated in a hydraulic damper of a suspension by the weight of the driver when getting in the car, the force of opening the driver's side door, the force of stepping on the brake pedal, etc.
