A saddle-type vehicle has an engine having an intake port, a fuel tank in fluid communication with the engine, and a heat shield. A snorkel defines a flow passage and a passage opening. The flow passage is in fluid communication with the passage opening and the intake port. The flow passage has an upstream portion that has a centerline. The heat shield at least partially defines a chamber in fluid communication with the passage opening. During operation, the engine draws air through the chamber, the passage opening, and the flow passage. The heat shield includes a reflecting wall extending at an oblique angle to the centerline. 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. |
