摘要： A snowmobile includes an engine, a handle, an operation portion, an operation input detector, an operation amount detector, and a control portion. The handle includes a grip grasped by the rider. The operation portion is provided near the grip to control driving of the engine. The operation input detector is provided near the grip to detect whether operation of the operation portion has been carried out by the rider. The operation amount detector electrically detects the operation amount of the operation portion. The control portion controls driving of the engine based on the operation amount detected by the operation amount detector when operation of the operation portion by the rider is detected at the operation input detector.

摘要： A snowmobile includes an engine, an engine power controller, an operation portion, an operation input detector, an operation amount detector, and a control portion. The control portion does not control the engine power controller based on an amount detected by the operation amount detector in a preliminary zone in which the operation amount detected by the operation amount detector is not more than a first operation amount. The control portion controls the engine power controller based on an operation amount detected by the operation amount detector if the operation amount is greater than the first operation amount. A second operation amount smaller than the first operation amount is set in the preliminary zone and the control portion determines whether operation of the operation portion is carried out based on whether operation corresponding to the second operation amount is detected by the operation input detector.

摘要： An air intake device of an engine includes a throttle body provided in an intake passage of an engine, a bypass passage arranged to connect an upstream side and a downstream side of a throttle valve disposed in the throttle body, an idle number-of-revolutions control device that is disposed in the bypass passage and that controls the quantity of air passing through the bypass passage and flowing into the downstream side of the throttle valve according to the state of the engine, and a water collection portion that is disposed on the upstream side of the idle number-of-revolutions control device in the bypass passage and that is constructed so as to include a space portion connecting with the bypass passage. This structure enables smooth operation of the idle number-of-revolutions control device and prevents damage thereto caused by water in a bypass passage.

摘要： In an engine intake system, an air cleaner and downstream sides of throttle valves in throttle bodies provided in intake passages are connected by bypass passages. An idle speed control apparatus provided at a midpoint of the passage controls amounts of air supplied during an idling operation. End portions of the bypass passages connected to the throttle bodies are located in higher positions than end portions of the bypass passages connected to the air cleaner so that the bypass passages are inclined downward toward the air cleaner. As a result, water is prevented from blocking the bypass passages via a simple structure.

摘要： A decompression system for a four-cycle engine includes a decompression shaft positioned within a camshaft. The decompression shaft interacts with decompression pins positioned within pin holes formed in the camshaft. In some embodiments, the decompression shaft is formed from a first longitudinal portion and a second longitudinal portion. In other embodiments, the decompression shaft is supported at least in part by a middle portion of a bore that extends through the camshaft.
