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.

Engine exhaust heat management system

An apparatus facilitates multiple paths or circuits through an engine and remote housing for an oil filter. The apparatus includes a first oil filter chamber housing a first oil filter, a second oil filter chamber housing a second oil filter, a first output of the remote housing configured to provide a path from the first oil filter chamber housing to bearings of an engine, a second output of the remote housing configured to provide a path from the second oil filter chamber housing to a sump of the engine, and an input of the remote housing configured to provide a path from an oil pump of the engine to the first oil filter chamber housing.
