Abstract

Two micro injection pumps technology were introduced to a new fuel injection concept called micro-pulsation fuel injection system. A micro thermal bubble injection pump made by MEMS fabrication process had 100 micropumps with nozzle of 80μm diameter to be built in a chip. The flow rate achieves about 4.9cc/min with less than 90μm droplet size and 1.5×10⁹ cycle time at 2 kHz. The piezoelectric plate pump included a small bimoph piezoelectric plate and 3mm × 7mm ×100μm array nozzle plate ejects about 2.4cc/min flow rate with about 49μm SMD droplet size at 17kHz frequency.
