Title: Fuel injection system
Inventor: FURUHASHI TSUTOMU
IPC: F02M47/00
Filed: 1995-04-04
Abstract: PURPOSE: To attenuate pressure wave easily with simple constitution, and control the term of injection, the amount of injection, or injection rate with high accuracy. CONSTITUTION: An orifice 20 is made in the vicinity of the accumulation chamber 5a of a first fuel passage 4a made in each branch supply pipe 4. The pressure wave generated by the opening and closing of an injection valve 2 is reflected partially at the orifice 20, and other components are reflected, with their phases inverted by the sectional area magnifying action at the boundary between the first fuel passage 4a and the accumulation chamber 5a. Since the distance between the orifice 20 and the boundary is smaller enough than the wavelength of the pressure wave, these two reflected waves absorb shock with each other with the phase difference of approximately 180 deg., the pressure waves are attenuated. Moreover, the pressure wave propagated from the accumulation chamber 5a the other injection valve 2 is attenuated while it permeate through the orifice two times.  Therefore, this can reduce the injection period of the injection valve being changed by the pressure wave generated by the opening and closing of the injection valve.
