Abstract
A pair of air inlet openings and a pair of air introduction paths are formed in a leftwardly and rightwardly symmetrical relationship on left and right side portions of a windshield. The air introduction paths are each formed as a smooth continuous curved face in a transverse direction, and a body center side curved face of the air introduction path is formed more moderate relative to an outer side curved face. When surface air flows along the surface of the front face flow on the air introduction paths since the body center side curved faces are moderate, exfoliation occurs less likely, and the external air admission efficiency of the air inlet openings is raised.
Claims17
An ambient air supply for a motorcycle engine comprising:
- a windshield adapted for covering a front portion of a motorcycle body, said windshield having a center portion and outer edge portions;
- at least one air inlet opening provided on said windshield;
- at least one recessed groove being formed in a surface of said windshield forwardly of said at least one air inlet opening providing a substantially longitudinal air introduction path to said at least one air inlet opening, said at least one recessed groove having a smooth, continuously curved surface in a transverse direction of said air introduction path;
- a first portion of said curved surface adjacent the center portion of said windshield being convexly shaped having a first radius of curvature;
- a second convexly shaped portion of the curved surface adjacent one of the outer edge portions of said windshield having a second radius of curvature substantially less than said first radius;
- and
- an intake conduit being in communication with said at least one air inlet opening for introducing ambient air to the engine.
An ambient air supply for a motorcycle engine comprising:
- a windshield adapted for covering a front portion of a motorcycle body, said windshield having a center portion and outer edge portions;
- a first air inlet opening provided on a first side of said windshield and a second air inlet opening provided on a second side of said windshield;
- a first recessed groove being formed in a surface of said windshield forwardly of said first air inlet opening providing a first substantially longitudinal air introduction path to said first air inlet opening, said first recessed groove having a smooth, continuously curved surface in a transverse direction of said first air introduction path;
- a second recessed groove being formed in a surface of said windshield forwardly of said second air inlet opening providing a second substantially longitudinal air introduction path to said second air inlet opening, said second recessed groove having a smooth, continuously curved surface in a transverse direction of said second air introduction path;
- a first portion of each of said curved surfaces of said first and second recessed grooves disposed adjacent the center portion of said windshield being convexly shaped having a first radius of curvature;
- a second convexly shaped portion of each of said curved surfaces adjacent a respective one of the outer edge portions of said windshield having a second radius of curvature substantially less than said first radius;
- a first intake conduit being in communication with said first air inlet opening for introducing ambient air to the engine;
- and
- a second intake conduit being in communication with said second air inlet opening for introducing ambient air to the engine.
A windshield adapted for covering a front portion of a motorcycle body, said windshield having a center portion and outer edge portions comprising:
- at least one air inlet opening provided on said windshield;
- at least one recessed groove being formed in a surface of said windshield forwardly of said at least one air inlet opening providing a substantially longitudinal air introduction path to said at least one air inlet opening, said at least one recessed groove having a smooth, continuously curved surface in a transverse direction of said air introduction path;
- a first portion of said curved surface adjacent the center portion of said windshield being convexly shaped having a first radius of curvature;
- a second convexly shaped portion of the curved surface adjacent one of the outer edge portions of said windshield having a second radius of curvature substantially less than said first radius.
