Abstract
A snowmobile includes an engine including an engine head including a cylinder head, a supercharger, an intake manifold, throttle bodies, first joints that connect the intake manifold to the throttle bodies, second joints that connect the throttle bodies to the cylinder head, and a restrictor that connects the engine head to the first joints. The restrictor includes an engaging member that fits into grooves of the first joints, and connectors that connect the engaging member and the engine head to each other. A steering shaft is inserted between two mutually adjacent first joints which have a distance from each other greater than a distance between the other two mutually adjacent first joints.
Claims14
A vehicle comprising:
- an engine including an engine head including a cylinder head and a head cover disposed on the cylinder head;
- a throttle body that supplies air to the cylinder head;
- a supercharger;
- an intake manifold that is supplied with compressed air from the supercharger;
- a first joint that connects the intake manifold and the throttle body to each other;
- and
- a restrictor that connects the engine head and the first joint to restrict relative movement of the first joint with respect to the engine head;
- wherein
- the throttle body and the intake manifold are spaced apart from each other with the first joint located therebetween.
