Abstract

DC60 alternator (21) generates AC power when the crankshaft of the engine-motor (10) is supplied with output power. The power of the alternator (21) is voltage controlled. For example, 14V by a controller (23) a relay normally closed (25) is connected to the fuel pump (15) and when the VP pump voltage is supplied to The fuel pump (15) The fuel pump (15) is installed inside one of the ECUs (30) the power source IC (33) generates the VCC power source pressure. One (35) is supplied with a VCC microcomputer power source voltage. The machine (35) has been started. When such microcomputers (35) were sent out The cylinder stop signal after ignition (10) was completed, the solenoid (25b) was triggered in bringing the normally closed switch (25a) to the open state, with the power being supplied. Also the fuel pump (15) had been stopped and hence the fuel-fire pump (15) had been stopped. The alternator (21) produces AC power when the crankshaft of the engine-motor (10) is supplied with power.

Claims (4)

1. Fuel injection equipment for engines consisting of Generator (21) for power generation The propulsion from the engine (10) the fuel pump (15) to increase the fuel pressure and to supply the oil. The pressure-boosted fuel goes to the fuel injector (13), the fuel pump (15), driven by the power supplied by the generator (21), the control unit ( 35) to control the fuel pump (15) the control unit (35) received The control of the operation by the power being supplied by the generator (21) and the switching device (25) is provided in the way through the flow of the fuel pump (15) in which the switching device Such wires (25) are usually in a state in which electric current flows in the path. The passage of such current and when one of the precedent conditions was established after the attachment Engine (10) Such switching device (25) is operated by a control unit (35) to interrupt its path through that current. 2.Fuel injection devices for engines in accordance with claim 1, in which such a switching device (25) includes a normally closed relay switch (25a) and a solenoid (25). To bring the aforementioned relay switch (25a) into an open or closed state and the control unit (35) stimulates the solenoid (25b) to turn on the said relay (25a) to interrupt the way through that current. 3. The fuel injection device for the engine in accordance with claim No. 1, where the aforementioned current path, including the first path (S1-S2), was introduced into the state In one such state, electric current flows when the aforementioned control unit (35) is not regulated. Work and a second path (S1-S3) that may be switched by the control unit (35) between one state in which the current is passed and one in which the current is interrupted. Switching device (40) switches the path through the current between the first and the second path. When the engine has been started The fuel pump (15) is also dispensed. Power through the first path (S1-S2) and after engine start-up is complete. The path through the current has been alternated to the path Second way (S1-S3) 4. The fuel injection device for the engine complies with claim 3, where the current path is switched to the second route by controlling the switch-over device (40) after the time of receipt. A specified period is elapsed from a certain time when the Generator (21) Starting power distribution
