<p>PURPOSE:To secure safety of a vehicle and indicate a control condition of an engine, by detecting a turbocharger operation through a plurality of pressure detection means to energize a fuel supply mechanism, and providing an indication means operable according to detected pressures. CONSTITUTION:Both of pressure switches PS1 and PS2 are closed upon rapid acceleration to an extent greater than a predetermined level, and a solenoid of a relay RL1 is energized to go on and thereby to energize a fuel injector 10. Accordingly, fuel is injected and an engine output is increased to rapidly accelerate a vehicle. In other words, only when an acceleration condition to an extent greater than a predetermined level is detected, a supercharged pressure is increased over a predetermined level for a predetermined time to operate the injector 10 and supply an additional fuel to increase the engine output. When a turbocharger is operated, a vacuum in an air intake pipe 5 is decreased, and a contact point of the switch PS1 is closed to apply voltage to light emission diodes LE1 and LE2, thereby emitting a green light, where the diode LE2 is in an OFF condition. Thereafter, when the output is further increased and the pressure in a tank 9 exceeds P1, the contact point of the switch PS2 is closed to energize the diode LE2, thereby emitting a yellow light and indicating a control condition of an engine.</p> |
