Abstract

DC60 (29/07/52) issues to be fixed. To equip an air-cooled vehicle engine unit Force, which provides a simple structure, higher flexibility of vehicle flowcharts. And efficiency Higher combustion fuel And to provide a motorcycle with such a motor unit. Supplementary air air boundary assembly 41 is connected to the auxiliary air inlet, 36 which is connected to the cylinder head, 23 of the auxiliary air channel scope 41 is defined. It was branched from the main airway P1 in the 36 such intake ducts to guide the intake. At least one of the 41 auxiliary air passes are bounded by the injector nozzles during idling. Outside the deflector, 50 parts around the injector were cooled by air. Assisted from the passage of the aforementioned K1 air during idling. The part surrounding the injection. It was cooled by the cooled air generated by the fan 56 during the vehicle's drive. The selected drawing. Figure 5 Problems to be solved. To equip the vehicle engine unit that is air-cooled Force, which has a simple structure, higher flexibility of the vehicle flowchart. And efficiency Higher combustion fuel And to provide a motorcycle with such a motor unit. Supplementary air air boundary assembly 41 is connected to the auxiliary air inlet, 36 which is connected to the cylinder head, 23 the auxiliary air channel boundary 41, the auxiliary air channel K1, the said K1 auxiliary air boundary. Branched from the main airway, P1 in the aforementioned 36 inlet ducts to guide the intake. At least one of the 41 auxiliary air passes are bounded by the injector nozzles during idling. Outside the deflector, 50 parts around the injector were cooled by air. Assisted from the passage of the aforementioned K1 air during idling. The part surrounding the injection The vehicle is cooled by the hot air generated by the fan 56 during the driving. The selected drawing is Figure 5.
