Supercharger Structure for an All Terrain Vehicle or a Utility Vehicle

A supercharger structure for an all terrain vehicle or a utility vehicle includes an engine body and a supercharging device. The engine body includes a cylinder having an intake passage and an outtake passage. The supercharging device includes a supercharger, a throttle, an intake manifold, and at least one nozzle. The supercharger includes a chamber having an inlet coupled with the throttle and an outlet connected to the intake manifold. The intake manifold and the at least one nozzle intercommunicate with the intake passage. The at least one nozzle is connected to a fuel supply pipe of a vehicle. External air is drawn in by a guiding device in the chamber, flows through the throttle and the inlet into the chamber, and is pressurized. The pressurized air flows through the intake manifold to mix with fuel ejected by the at least one nozzle and then enters the cylinder.
