Abstract
A dual fuel engine includes an engine operable on a gaseous fuel and a liquid fuel and a switch to change operation of the engine between gaseous fuel and liquid fuel. The dual fuel engine also includes a carburetor attached to an intake of the engine to mix air and fuel and connect to a gaseous fuel source and a liquid fuel source. A liquid fuel cut-off attaches to the carburetor to interrupt liquid fuel upon actuation of the switch from liquid fuel to gaseous fuel.
Claims19
A dual fuel generator comprising:
- an engine operable on a gaseous fuel and a liquid fuel;
- an electrical power generator driven by the engine and comprising a charging coil;
- a switch to change operation of the engine between gaseous fuel and liquid fuel;
- a carburetor attached to an intake of the engine to mix air and fuel and connect to a gaseous fuel source and a liquid fuel source;
- a liquid fuel cut-off solenoid to interrupt liquid fuel flow to the engine upon actuation of the switch from liquid fuel to gaseous fuel;
- and
- a voltage regulator coupled to the charging coil to receive power therefrom and that operates to provide a regulated voltage to the liquid fuel cut-off solenoid.
A dual fuel generator comprising:
- an engine operable on a gaseous fuel and a liquid fuel;
- a carburetor attached to an intake of the engine to mix air and fuel and connect to a gaseous fuel source and a liquid fuel source;
- and
- a manually actuated fuel shutoff coupled to the carburetor, the manually actuated fuel shutoff comprising:
- a first end in the carburetor that actuates to selectively allow or block a flow of fuel through the carburetor;
- and
- and a second end external to the carburetor to actuate the first end.
