Problems solved by technology

[0007] In addition, when the two-wheeled motor vehicle is running, when the electromagnetic fuel pump 6 fails, the control of the electromagnetic fuel pump 6 is stopped, so after a certain distance is traveled with the fuel in the carburetor 9, the engine output decreases.

Embodiment Construction

[0047] Embodiments of the present invention will be described below with reference to the drawings. The drawings are viewed in the direction marked in the drawings.

[0048] 1 is a side view of a two-wheeled motor vehicle equipped with an electromagnetic fuel pump of the present invention. The two-wheeled motor vehicle 10 is a scooter-type vehicle. In the motorcycle 10 , a start switch 12 is attached to the handle 11 . Below the handle 11 is arranged a main switch 13 which also serves as a handle locking device, and a magnetic gate key is provided in a key insertion port. The engine control unit 16, radiator storage box 157 and battery 18 that carry out engine 15 ignition control (ignition with the CDI device described later) and power control are disposed in the rear cover 14 covering the rear lower part of the vehicle seat and the rear wheel top. A kick start pedal 23 is attached to a unit swing type engine 22 composed of an engine 15 and a belt conversion type continuousl...

Abstract

Control means 55 has a first operation mode set when a battery voltage VB with which a starter motor 33 can operate is detected, and a second operation mode set when a battery voltage VB with which the starter motor 33 cannot operate is detected and different from the first operation mode, and operation of a fuel pump 26 upon starting is controlled in either first operation mode or second operation mode. In a case wherein an engine is started by a kick starting apparatus and another case wherein the engine is started by a starter motor starting apparatus, preferable starting control of an electromagnetic fuel pump upon starting can be carried out with different control functions from each other. Thus, the engine startability by the kick starting apparatus, for example, when fuel is not present in a carburetor, can be improved. On the other hand, upon starting of the engine by the starter motor starting apparatus, electric power to be supplied to the fuel pump can be suppressed.

Description

technical field [0001] The present invention relates to the control method of the engine start of the electromagnetic fuel pump which is suitable for starting the engine with a starter motor and starting the engine with a foot pedal, and relates to a control method for electromagnetic fuel pumps equipped with electromagnetic fuel pumps when the electromagnetic fuel pump fails. A method of controlling the motor of the pump. Background technique [0002] Conventionally, a method of controlling a fuel pump at engine start of a motorcycle is disclosed in, for example, Japanese Patent Laid-Open No. 60-188867 "Fuel Pump for a Motorcycle". [0003] In the two-wheeled motor vehicle shown in FIG. 1 of the above-mentioned publication, the engine 1 is provided with an electromagnetic fuel pump 6, and the engine 1 is rotated by pedaling the starter pedal, and the ignition pulse is generated by the CDI unit 11, and the pedal operation is detected. Then, power is supplied to the electrom...
