Title: Fuel injection valve
Inventor: SATO YASUO
IPC: F02M61/16
Filed: 1984-12-19
Abstract: PURPOSE:To sharply limit exhaustion of discharged smoke by promoting atomization by supply fuel only from a first fuel path in low speed operation by making use of a first-stage lift action and thereby assuring a strong turning motion for the fuel flow. CONSTITUTION:Fuel pressure by an injection pump 38 is relatively low in low speed operation of an engine 39, and so first valve opening pressure of a spring 27 for supporting a pin 26 is kept lower than second valve opening pressure of a spring 30 for supporting a pin 29. Thereupon, a needle 25 is moved by a distance (d) against the spring 27, whereby pressure fuel enters into paths 48, 50, and is subjected to a violent turning motion in a turning chamber located on the tip end of a nozzle body 23 owing to a slanted groove 57 formed in a constriction part 63 surface and injected from an injection orifice 60 in a wide angle, and hence it is sufficiently mixed with air. While, since the fuel pressure is higher in high speed operation, the needle 25 is lifted to a distance D (>d) against the springs 27, 30, and the pressurized fuel passes through the paths 48, 66, and 52-56, and the turning chamber 51 and joins with fuel passing through the path 50 and the slanted groove 57, and finally injected with a relatively slow curvature and with sufficient penetration force.

Title: Control device of solenoid driven valve for internal combustion engine
Inventor: SAWADA TAKASHI
IPC: F02D41/20
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To save power in the initializing control of a solenoid-driven valve supported resiliently by a spring in the neutral position wherein the initializing control signifies a displacement from the neutral position to the full closed or full open position. SOLUTION: The initializing control of a solenoid-driven valve is performed in such a way that the amplitude of the valve element is increased gradually by exciting the natural vibration of a spring mass system. In this initializing control using resonance phenomenon, an electromagnetic force is generated in the full close direction if a piston is in the up-stroke when the initial displacement is to be given while the position is in neutral (S4) and in the full open direction if the piston is in the down-stroke (S5) so that the dynamic pressure of the air acts in the same direction as the electromagnetic force.
