摘要： A multi-fuel engine includes an engine operable on a liquid fuel and first and second gaseous fuels. The multi-fuel engine also includes a liquid cutoff solenoid selectively operable between open and closed positions to allow and inhibit a flow of the liquid fuel to the engine and at least one gaseous cutoff valve selectively operable between open and closed positions to allow and inhibit a flow of the first and second gaseous fuels to the engine. A jet block couples the first gaseous fuel source and the second gaseous fuel source to a carburetor connected to an intake of the engine, with the jet block being located downstream from the at least one gaseous cutoff valve. The jet block includes a first gaseous fuel jet to meter the first gaseous fuel to the carburetor and a second gaseous fuel jet to meter the second gaseous fuel to the carburetor.

摘要： A system for combusting volatile vapors includes a carburetor having intake valves for receiving base fuel from a fuel source, ambient combustion air, and volatile vapors from a vapor source. A plurality of sensors measure and generate sensor data based on a respective plurality of physical properties associated with the carburetor and associate combustion engine operation. One or more programmable controllers receive the sensor data and control the intake valves to regulate respective ratios of the fuel, air, volatile vapors drawn through the carburetor based on the received sensor data. To increase the burn of volatile vapors, an engine loading system automatically operated by the controller(s) applies an automatically adjustable braking load on the engine. The load level applied is based on the sensor data and commensurate with maintaining stable engine running conditions. The loading system decreases time necessary to remediate a site.

摘要： A gaseous fuel pressure regulator uses an inlet valve and an outlet valve to regulate an incoming pressure, from a gaseous fuel supply tank, and accurately control the pressure at the outlet of the regulator. The control of the outlet pressure is maintained by precise movement of the outlet valve which is controlled by an actuator. The actuator receiving pulse width modulated signals from a microprocessor in order to maintain the outlet valve in an opened, or gas flow permitting, position for a time period which is appropriate to maintain the desired pressure at the outlet port of the regulator. An inlet port maintains a pressure within a conduit, which is connected in fluid communication between the inlet port and the outlet port at an intermediate pressure which is used by the outlet valve to achieve the desired outlet pressure magnitude.

摘要： A fuel and air mixture induction system is provided for an internal combustion engine and includes a conventional air and fuel mixing carburetor for starting the engine when the latter is cold. However, when operating temperatures of the engine are reached the air and fuel induction system is operative to more thoroughly vaporize liquid fuel by pressurizing and heating not only the induction air but also the fuel and spraying the heated fuel into the heated induction air in a manner such that substantially complete fuel atomization and vaporization occurs. This pressurized fully vaporized fuel and air charge is thereafter discharged in a downstream direction into the air and fuel passage of the carburetor closely upstream from the venturi area thereof. The supply of liquid fuel to the carburetor is maintained, but the fuel flow from the carburetor float chamber is automatically reduced when the supply of vaporized fuel and air is furnished because the air and vaporized fuel is supplied to the carburetor under a low pressure thus effectively reducing the reduced venturi area pressure normally associated with a carburetor and the flow of fuel from the carburetor float chamber to the venturi area. In addition, normal opening of the throttle valves is decreased when the supply of heated air and fully vaporized fuel is supplied to the carburetor. Therefore, a smaller amount of air and fuel vapors pass through the carburetor to further reduce the vacuum at the venturi passage and thus the flow of fuel from the carburetor flow chamber into the venturi passage.

摘要： A gaseous fuel delivery system for a gasoline engine having means for gaseous fuel delivery comprising idle fuel delivery means and acceleration fuel delivery means. Electrically operable means responsive to ported vacuum in the carburetor throat controls operation of the idle fuel delivery means. Electrically operable means responsive to intake manifold vacuum controls operation of the acceleration fuel delivery means. An idle switch responsive to idle position of the throttle prevents opening of the idle fuel delivery means except when the throttle is in the idle position.The engine carburetor is arranged such that no gasoline is delivered for idle operation. Idle needle valves are closed, or eliminated. Transition slots are sized to be operational only as the throttle moves from the idle position and supply no fuel when the throttle is at idle.
