    Abstract: A gas-diesel dual fuel engine operative with both a gaseous fuel and a diesel fuel oil. The engine has an electronic governor circuit adapted to receive both a speed signal representing actual speed of engine and a set speed signal representing a predetermined command speed of the engine, electric actuators adapted to actuate a diesel fuel injection pump and a gaseous fuel regulating valve, respectively, in response to the signal from the electronic governor circuit, and a mode switching control circuit connected to the electronic governor circuit and adapted to switch the operation of the electric actuators between a diesel fuel operation mode and a gaseous fuel operation mode.

    Abstract: A turbo-charged, inter-cooled governed speed diesel engine directly coupled to an alternator for electrical generation is adapted for dual-fuel operation and mounted on a trailer which also supports the engine's fuel sources including diesel fuel in a conventional tank. The second fuel is producer gas generated in a down draft continuously operating producer of the moving-packed-bed vertical flow reactor type with co-current gas flow. Solid waste such as crop residues, e.g., corn cobs, is used as fuel stock for the producer and is conveyed automatically to the producer from a bin on the trailer. Before delivery to the air intake of the diesel engine the producer gas is conditioned by passing it through a cyclone and filter to remove solid particulate matter and a cooler-condenser for cooling the gas and condensing out tars. The diesel governor and fuel pump assembly is modified only by the application of a fuel rack stop for maintaining a pilot flow of diesel fuel and the engine control system is such that the response of the diesel injection system to changes in engine load is normal in general; however, automatic controls are provided for monitoring diesel pump fuel rack position and engine load so that after engine loading is increased a throttle valve in the gas supply to the engine is progressively and relatively slowly opened tending to increase engine speed so that the diesel injection rate is conventionally cut back correspondingly until an equilibrium condition is reached in which engine fuel demand in excess of the pilot minimum diesel fuel flow required to maintain combustion is provided by producer gas. The response of the system to a decrease of engine loading when the engine is operating at minimum diesel fuel flow (that is with the fuel rack stop effective) is to reduce fuel supply rapidly and appropriately by partially closing the gas throttle valve. Automatic safety shutdown provisions include, in at least one shutdown mode, delayed shutting off diesel fuel flow following producer gas shutoff so that the engine and exhaust system are purged of producer gas so as to reduce explosion hazards.

    Abstract: A bi-fuel control system and assembly for modifying and operating a diesel engine (30) to the extent that the engine is capable of running in either a full diesel fuel diesel mode or a bi-fuel mode, where bi-fuel is defined as a mixture of a methane based gas (10) and diesel fuel. The control system and assembly are designed to provide for either manual or automatic transfer between modes for continuous engine operation without interruption in output and at substantially equivalent efficiency levels. A gas control sub-system and sub-assembly are provided to control the amount of gas supplied to the diesel engine (30) in the bi-fuel mode, and an electronic control sub-system and sub-assembly are provided to control the overall system and assembly based on engine load as determined from the intake manifold air (28) pressure.

    Abstract: A system and assembly for modifying a diesel powered electric generator preferably of the reciprocating engine type (30) to the extent that the generator is capable of running on either 100% diesel fuel or in a "bi-fuel" mode which is defined as a mixture of methane based gas (10) and diesel fuel. The system and associated assembly is specifically designed to provide for the automatic or manual switching between the full diesel mode and the gas-diesel fuel or bi-fuel mode for continuous generator operation without interruption in generator output and at substantially equivalent or comparable efficiency levels.
