The Development of a New Fuel Injection System for Two-Wheel Vehicles 911233

We have developed a new self-control multi-point fuel injection system (hereinafter called ”SFCI-M”) for two-wheel vehicles. This paper discusses the development results and technical features of the SFCI-M.
Multi-point injection (MPI) systems for two-wheel vehicles have been unpopular somewhat. For one thing, an MPI was more expensive than a carburetor. For another, its performance has left something to be desired. However, the situation has come to justify the production of MPI units for two-wheel vehicles. The factors which have led to this trend are, among others:
  1. a)
    Costs of MPI units for four-wheelers have come down.
  2. b)
    Interest in two-wheel vehicles featuring electronically controlled devices such as ignition systems has gained momentum.
  3. c)
    Prices of two-wheel vehicles have become higher reflecting high-value-added tendency.
