Title: Fuel injection method and device of diesel engine
Inventor: SUZUKI TAKAO
IPC: F02B3/06
Filed: 1983-04-11
Abstract: PURPOSE:To decrease the generation of noise and white smoke at idle operation of an engine and promote its optimum combustion at high load operation of the engine, by controlling the opening area of a needle valve rod, which is lifted in accordance with a rise of fuel pressure in a fuel reservoir chamber, to be initially increased, secondly decreased and gradually increased. CONSTITUTION:If fuel is supplied to the oil reservoir chamber of a nozzle seat 7 increasing its internal pressure, a needle valve rod 9' is lifted but only about detached from a tapered surface 17 of the nozzle seat 7 due to a small amount of supply of the fuel for a short time of the pressurizing action. Then the fuel is injected from a nozzle opening 20 of an area S provided between a bottom end opening 14 of the seat 7 and a rod 19 of the rod 9'. This throttled flow Q, being larger by the increased area as shown by a curve in the drawing, enables a flow of the fuel to be ensured even if carbon adheres in the vicinity of the opening 20. If an engine load is increased, the rod 9' is further lifted, and the tapered portion of a metering flange 21 decreases the area to form an opening 20', holding the flow of the fuel to a fixed rate till the flange 21 passes through the opening part 14. Next, the opening 20' is changed to an opening 20'' by an increase of the load, causing the flow of the fuel to reach a maximum rate and enabling the most suitable combustion of an engine.

Title: Power failure control circuit
Inventor: SHIGEOKA FUMIAKI
IPC: G06F1/30
Filed: 1988-03-16
Abstract: PURPOSE:To cause an electric apparatus to stably make a restarting operation without making any unstable operation by utilizing the residual voltage of the source power source of the apparatus at the time of a power failure by securing a sufficient resetting operation time against the apparatus when the source power source breaks down and canceling the resetting operation after the source power source sufficiently restores at the time of restoration. CONSTITUTION:When a power failure takes place at time t0, a power failure detector 4 is actuated and an on-delay timer 5 starts time limiting operations. If the power failure continues even time t1 is reached, the output signal C of the timer 5 becomes a low level from a high level and gives a power failure signal to the electronic control circuit 3. At the same time, the output signal causes a timer 7 with reset to start time timing operations. The circuit 3 resets the time limiting operations of the timer 7 by raising the level of its output signal D from a low level to a high level after power failure restoring operations are processed and causes a timer 6 to start time limiting operations by making the input of a two-input OR gate 8 effective. When the power failure is restored at time t4, power supply is restarted after a sufficient time, during which the output signal of the on-delay timer 5 become high in level, and so forth.
