摘要： PROBLEM TO BE SOLVED: To provide an injector control device capable of improving a valve opening operation characteristic of injectors by simple processing. SOLUTION: When respective injectors reach valve opening time, a valve opening signal is turned on for a predetermined valve opening time τ. A control circuit turns on a starting signal for a preset time τp1 when the valve opening signal is turned on when a starter signal shows a driving state of a starter motor, and turns on the starting signal for a preset time τp2 shorter than the preset time τp1 when the valve opening signal is turned on when the starter signal shows a stopping state of the starter motor. Therefore, supply time of a starting current supplied to the injectors becomes long for a prescribed period after starting an engine, and becomes short after a prescribed time passes. The prescribed period after starting the engine may be a period until an engine speed reaches a prescribed engine speed, a period until a water temperature of engine cooling water reaches a prescribed value and a period until battery voltage reaches a prescribed value.

摘要： PROBLEM TO BE SOLVED: To improve cleanliness of exhaust gas and fuel consumption performance by making gaseous fuel collide against intake air flow, and evenly mixing air with the gas fuel. SOLUTION: In this mounting method for an injection valve of a natural gas engine, an injection valve 6 is arranged on a side wall of an intake pipe 27 in a downstream of a throttle valve 25. An injection port of the injection valve 6 is directed opposedly to intake air for injecting natural gas fuel only in the intake stroke. The injection valve 6 is arranged on the outer side of a bent portion of the intake pipe 27, and also in the downstream thereof. The natural gas fuel is injected to an area where velocity of the outer intake air is relatively higher compared to the center axis of the bent portion.

A canister 13 is purged via a check valve 24 which is opened by the action of negative pressure under predetermined pressure. Then, when an operation is stopped and the valves 6, 8 are closed, a first open/close valve 20 is opened and a second open/close valve 22 is closed and the gaseous fuel remaining in a fuel distributing pipe 4 and a fuel supply passage 2a which are disposed between the valves 6 and 8 is introduced into the suction room 17 of the canister 13 via a suction passage 19 and is adsorbed by an adsorbent 14. The adsorbed fuel is purged into the engine 3 when the engine is started.

摘要： PROBLEM TO BE SOLVED: To improve the reliability in the operation of an engine by detecting the delivery gas pressure before the start of the valve driving or at the start of the same, and the delivery gas pressure after the start of the valve driving, and the fastening of an injector valve is judged when the difference between the detected gas pressures is less than a predetermined value. SOLUTION: A CPU 2 in an ECU 1 executes the injection control 5a of a gas injector on the basis of detection signals from various sensors such as a throttle sensor 35, a water temperature sensor 27, an intake pressure sensor 36, an A/F sensor 38 or the like. Further it executes the lighting or flickering control 5b to a warning lamp, executes the ignition timing control 5c to an ignition plug, and executes the control 5d to an ISC valve. On this occasion, the pressure at the start of the energization to a gas injector is compared with the pressure after the lapse of a predetermined time from the start of energization with respect to the pressures detected by the delivery pipe gas pressure sensor 18. When the deviation of the pressures is below a predetermined value, the fastening of the injector valve is judged, and an energization time is elongated for a specific time.
