N2 - According to small-displacement gasoline engine's wide speed range and small fuel requirement, a new kind of Electronic Micro Multiple Fixed-Volume Fuel Injection System was proposed, and then the electronic-magnetic-mechanic-hydraulic coupled mathematical system model was built, after that the transient response characteristic from input voltage actuation to output fuel injection was analyzed, also the key parameters were deduced. Results show that injection system's high speed response frequency can reach 1000 Hz which meets the highest engine speed requirements of small displacement engine, and this new injection system work principle is correct in theory.
