摘要： An engine filter assembly for cleaning cooling air for an internal-combustion engine for use in high-debris environment such as in roofing-removing machines includes a filter housing attached to the machine at a remote position. The filter housing houses a two-stage air filter that consists of a cylindrical-shaped filter element with an outer pre-filter covering. Both the carburetor air inlet and a fan housing leading to the cooling fan on the engine are connected to the filter housing by tubing. A shield protects the engine from direct contact with loose or air-borne materials during the operation of the machine. A thermal sensing device reads the temperature of the engine and automatically shuts down the engine if the temperature rises beyond specification, reducing the chance of engine failure.

摘要： An engine filter assembly for cleaning cooling air for an internal-combustion engine for use in high-debris environment such as in roofing-removing machines includes a protective element housing attached to the machine at a remote position. The protective element housing houses a two-stage air filter having a cylindrical-shaped filter element with an outer pre-filter covering. An air inlet housing on the engine is connected to the protective element housing by a flexible coupling link. A shield protects the engine from direct contact with loose or air-born materials during the operation of the machine. A thermal sensing device reads the temperature of the engine and automatically shuts down the engine if the temperature elevates beyond specification, reducing the chance of engine failure.
