The Ultra-Mini Fuel Injection Pump Development for Small Air-Cooled Diesel Engines

Abstract

Diesels are making ground in the world's engine markets, and this tendency is now more apparent than the growth and technical progress of small diesel engines. The performance of the fuel injection system clearly plays the crucial role in the promotion of diesel engine and its applications, and the pressure on research and and development are especially severe in this area. This include (a) completion of small and light weight units, (b) compliance with exhaust gas legislation, (c) reaction to fuel economy research as with the direct and high pressure injection systems, (d) development of new techniques for precise adjustment of spray and injection, (e) reaction to fuel versatility such as low grade fuel and (f) achievement of lower costs. In all of these area we must work for bettery quality, cost saving, maneuverability, comfort, safety and higher reliability for both the engines and their machines. More efforts into research and development shall be invested to meet the higher requirements of technology. Under the circumstances, the authors have developed the new small size, light-weight and low-cost fuel injection equipment. This can be adopted to small diesel engines for variety of purpose.
