Abstract

DC60 (22/01/47). In motorcycles according to this invention in the lower part of the seat 21 is installed. The engine is positioned cylinder head 3 at the front of the car body and at the top of the engine is an intake pipe 31 which extends from the top of cylinder head 3 towards the rear of the car body. There will be a sprayer 11 which sprays fuel. It is attached and has a nozzle mounting part in which the spray nozzle 11 a is positioned between the axis of the suction valve 7 and the axis of the 3g suction inlet, where the Adjacent to the end part of the intake valve of the 3g air intake, the sprayer 11 and the suction pipe 31 are positioned without obstructing each other. Therefore, because the sprayer 11 does not interfere with the intake pipe 31 on the engine. thus creating a gap between the lower part of the seat 21 and the intake pipe 31, and in the case of using this gap as the container 22, the obstruction between the sprayer 11 and the container can be avoided. And it can also avoid reducing the packing capacity of the box. On motorcycles according to this invention, the lower part of the seat 21 is installed. The engine is positioned cylinder head 3 at the front of the car body and at the top of the engine is an intake pipe 31 which extends from the top of cylinder head 3 towards the rear of the car body. There will be a sprayer 11 which sprays fuel. It is attached and has a nozzle mounting part in which the spray nozzle 11 a is positioned between the axis of the suction valve 7 and the axis of the 3g suction inlet, where the Adjacent to the lift end on the suction valve side of the 3g air intake inlet, the sprayer 11 and the air intake 31 are positioned so that they do not obstruct each other. Therefore, because the sprayer 11 does not interfere with the intake pipe 31 on the engine, it can create a gap. between the lower part of the seat 21 and the intake pipe 31, and in the case of using this gap as the container 22, the obstruction between the sprayer 11 and the container can be avoided. And it can also avoid reducing the packing capacity of the box.
