Abstract
We have extended application of fuel injectors (hereafter as “injector”) for small motorcycle engines in developing countries by making it compatible with various engine displacements and trims as well as satisfying the needs from a variety of operating and environmental conditions.
The motorcycles with a small-displacement engine are mainly for developing countries and often have an uncovered engine. Accordingly, a noise-insulating cover was indispensable to insulate injector noises.
Since it was necessary to attain a low cost for the complete motorcycle by eliminationof the noise-insulation cover for extensive application of an electronic fuel injection system (hereafter “FI”) in developing countries, we developed the quiet injector by thorough reduction of mass of the needle valve and lowering of the operation speed.
