きに通電され、弁６を開弁作動制御されるものである。The solenoid 5 of the electromagnetic valve is connected to a controller 10 by a harness. The controller 10 energizes the solenoid 5 to open the valve 6 when the vehicle is starting or at a very low speed, and when the engine is braking, that is, when the engine brake is activated when exiting the vehicle, or when fuel is not being blown, such as before the engine is stopped. It is controlled by valve operation.

よりトルクを向上する。Since the present invention is configured as described above, when the vehicle is started or at extremely low speed, the valve 6 of the air nozzle 4 is connected to the solenoid 51.
The valve is thus opened, and high-pressure air from the air tongue 8 is blown into the cylinder 2, thereby increasing torque by supplying fuel commensurate with the amount of air.

エアチャージが効果的に得られる。Solenoid valve 4 for air blowing and air charging
As shown in Fig. 4, the opening timing of the solenoid valve 4 is as shown in Fig. 4. In the case of air blowing, the solenoid valve 4 is opened at the beginning of the compression stroke when the engine is running at low speed, and in the case of air charging, the solenoid valve 4 is opened at the beginning of the compression stroke when no air blowing is required. The solenoid valve 4 is opened at approximately mid-term B, and the air blowing is performed at tC% as shown in Fig.
By setting the area within the cylinder to approximately 40%, and the air charge to an area of approximately 60ts within the cylinder, as shown in Figure 6, the black smoke concentration at the time of departure can be effectively reduced and air charging to the air tank can be effectively achieved. can get.
