AI Technical Summary

Technical Problem

Existing motorcycle configurations with superchargers face limitations in arranging the supercharger due to the need for power from the engine's rotation shaft, leading to potential pressure loss and reduced energy efficiency and responsiveness.

Method used

The configuration positions the surge tank above the cylinder block, the supercharger behind the surge tank, and the air cleaner above or below the supercharger, utilizing an electric motor as a power source for the supercharger, allowing for flexible placement and reducing pressure loss in the intake system.

Benefits of technology

This arrangement improves energy efficiency and responsiveness by eliminating the need for engine-driven supercharger power, enabling compact and protected placement of the surge tank, supercharger, and air cleaner, thereby reducing pressure loss and enhancing system efficiency.

Abstract

A motorcycle (1) comprises: an engine (E) provided with a cylinder block (42a) that protrudes obliquely forward and upward from a crankcase (41); an air cleaner (60) that filters intake air to the engine (E); a supercharger (70) that is provided with an electric motor (75) serving as a drive source, takes in air from the air cleaner (60), compresses the air, and supplies the compressed air to the engine (E); and a surge tank (80) into which supercharged intake air is introduced from the supercharger (70). The surge tank (80) is disposed above the cylinder block (42a). The supercharger (70) is disposed behind the surge tank (80). The air cleaner (60) is disposed above the supercharger (70).
