ABSTRACT:
A lawn mower which is powered by an engine that uses gaseous fuels, such as liquified petroleum gas (LPG), compressed natural gas (CNG) or liquified natural gas (LNG). It may be either built originally to use gaseous fuels, or it may be converted from using liquid hydrocarbon fuels such as gasoline or diesel fuel. It may also use a combination of gaseous and liquid hydrocarbon fuels. The lawn mower may be hand-pushed or be self-propelled. It may include a fuel injector having a cylindrical main body housing, a coupling connecting a fuel hose and the main body housing, a gaseous venturi retained within the main body housing, an air intake in the main body housing, a sleeve that can slide over the air intake, and a docking collar with a plurality of slots that fits over the main body housing. The fuel injection system uses blow-by to recirculate any unused fuel or air thereby increasing the efficiency of the injection system. The fuel injection system can be automated or operated manually. The valve is used with disposable small gas canisters.
