Abstract:
1. A saddle-type vehicle comprising: an engine comprising an intake port; a fuel tank in fluid communication with the engine; a snorkel defining a flow passage and a passage opening, the flow passage being in fluid communication with the passage opening and the intake port of the engine, and the flow passage comprising an upstream portion adjacent to the passage opening and extending along a centerline; and a heat shield positioned generally above the engine and comprising a reflecting wall, a guide wall contiguous with the reflecting wall, and a front wall spaced from the guide wall, the heat shield and the fuel tank at least partially defining a chamber in fluid communication with the passage opening, each of the reflecting wall and the guide wall being spaced from the snorkel and upstream of the passage opening, the reflecting wall extending at an oblique angle to the centerline of the upstream portion of the flow passage; wherein the reflecting wall is configured to reflect pressure pulses emanating from the passage opening back through the passage opening and toward the intake port during operation of the engine; the guide wall is positioned to guide the flow of ambient air into the chamber and forms an obtuse angle with the reflecting wall; and the guide wall is generally parallel with the centerline of the upstream portion of the flow passage.
