- To achieve a clean atmospheric environment and a stable fuel supply, considerations are being given to the use of methanol fuel as one of the fuel used by alternative fuel vehicles.This report describes the development and studies of a brushless motor-driven fuel pump to be employed for a methanol electronic fuel injection system.Several problems remained to be solved for the fuel pumps used with methanol fuel, and hence considerations were given to the following items:
-
(1)
A control unit was developed that can be used in high-pressure fuel. This unit has been downsized substantially due to the adoption of a system in which it is subjected to forced cooling with the fuel. The control unit can be mounted inside the fuel pump.
-

In order to cope with increased fuel consumption and other needs, the specifications of the motor and pump were studied, and highly corrosion-resistant materials were used for various components, increasing the performance and durability of the pump substantially.
