    摘要： An engine according to the present disclosure includes: a crankcase which supports a crankshaft of the engine; a cylinder which is removably connected to the crankcase and protrudes from the crankcase in a cylinder axis direction; a cooling fan which is attached to the crankshaft and rotates in conjunction with the crankshaft; and a cover which guides cooling air generated by the cooling fan to an outer surface of the cylinder. The cover includes an opening part which allows a portion of the cooling air to flow toward an outer surface of the crankcase.

    摘要： One embodiment of the invention relates to an internal combustion engine including an engine block, a crankshaft configured to rotate about a crankshaft axis, a flywheel coupled to the crankshaft, a throttle body, an electric fan, and an air filter assembly configured to filter incoming air from an air intake and provide cleaned air to a throttle body. The engine block includes a cylinder. The throttle body is configured to throttle incoming air to the cylinder.

    摘要： A heat management system for air-cooled engines suitable to power yard care equipment or vehicles. The system may generally comprise an engine, a blower configured to blow ambient cooling air across the engine, and an exhaust system comprising an exhaust header and a muffler. The exhaust header has an inlet end which receives heated exhaust gas from the engine and an outlet end fluidly coupled to the muffler. An air control baffle is configured to redirect a portion of the cooling air from the blower towards the exhaust header and the muffler to enhance cooling the exhaust system. The system may further include an outermost protective shield exposed to equipment operators and an inner heat barrier or shield located between the muffler and protective shield. The system is designed to ameliorate both radiative and convective sources of heat transfer to maintain the protective shield at temperatures below established industry standards.

    摘要： A utility vehicle includes: an air-cooled engine; a cooling fan disposed on one side of the engine with respect to a vehicle widthwise direction and configured to supply a cooling air towards a cylinder unit of the engine; an exhaust pipe disposed on the other side of the engine with respect to the vehicle widthwise direction and connected with an exhaust port of the cylinder unit; an oxygen sensor fitted to the exhaust pipe; and a shield configured to prevent muddy water, which is swirled by the cooling fan, from depending on the exhaust pipe.
