摘要： A snowmobile four-cycle engine arrangement, includes: a four-cycle engine arranged in an engine compartment formed in the front body of a snowmobile with its crankshaft laid substantially parallel to the body width and having a cylinder case inclined forwards with respect to the vehicle's direction of travel. The engine employs a dry sump oil supplying system and an oil tank separate from the engine is provided. Another snowmobile four-cycle engine arrangement includes: a four-cycle engine having a cylinder head at its top, arranged in the engine compartment and inclined forwards with respect to the vehicle's direction of travel with an intake path provided on the upper portion of the engine body. An intercooler for cooling the intake air is arranged in a tunnel created inside the body frame for accommodating a track belt.

摘要： In a cooling arrangement for a water-cooled snowmobile engine, a water pump is disposed on the front side of the cylinder head, under the exhaust manifold and is coupled to a crankshaft so that it is driven by the rotational force which is transmitted through a drive belt from a drive pulley fitted on the crankshaft end. A cooling water inlet port for leading cooling water into the interior of the engine is provided on the front side of the cylinder block and under the exhaust manifold while a cooling water outlet port through which cooling water is taken out from the interior of the engine is arranged on the cylinder head's side face at a position over and opposite to the drive belt and a thermostat is arranged at the cooling water outlet port.

摘要： In a snowmobile, a four-cycle engine has an alternator as a generator while the snowmobile body has heat exchangers through which the cooling water of the engine is cooled by heat exchange with external air and snow, in a front part and at the ceiling of a crawler house. The alternator is positioned between the four-cycle engine and the front heat exchanger. Further, an exhaust manifold is arranged at an upper position in front of the engine body while an approximately cylindrical oil filter is provided under the exhaust manifold and inclined forwards in the vehicle's direction of travel.

摘要： In a snowmobile, a four-cycle engine is mounted in such a manner that its crankshaft is arranged along the body width direction and the central axis of a cylinder(s) is tilted rearward by angle α with respect to the vertical direction of the body, forming a rear tilted engine. At least part of the engine intake system including an air cleaner box and throttle body, connected to the intake port(s) of the engine is accommodated in the space inside the topmost projected portion of the engine hood. Exhaust is led out to the muffler located in front of the cylinder(s) by the exhaust system connected to the exhaust port(s) at the front of the cylinder head. Further, the intake passage is arranged between the engine body and the steering post.
