Fluid Motor Means Driven By Waste Heat Or By Exhaust Energy From Internal Combustion Engine Patents (Class 60/597)
  • Patent number: 4201049
    Abstract: A turbine power plant of particularly inexpensive construction and using static expansion of the combustion gas to accelerate slugs of liquid used as the motive power for a Pelton wheel. The turbine power plant comprises a fuel combustion unit producing combustion gas which serves to impart speed to slugs of an auxiliary liquid, like water, in output pipes; this auxiliary liquid acts on a Pelton wheel to produce rotary drive. A part of the auxiliary liquid is reconverted as slugs to compress the air supplied to the fuel combustion unit. The turbine power plant also includes a second Pelton wheel driving a common shaft for an air fan, and a pair of rotating nozzles arranged to produce the said slugs of auxiliary liquid. The second Pelton wheel is driven by part of the auxiliary liquid.

  • Patent number: 4172479
    Abstract: A method and apparatus for use in tree felling for causing a tree to tip under the influence of a force acting on the cutting surfaces of a saw notch in the tree trunk. The tipping force is produced by means of an inflatable cushion which is inserted in a flattened state into the saw notch and connected to the combustion chamber of the cylinder of the power saw motor to be inflated with compressed gas from said combustion chamber.

  • Patent number: 4121422
    Abstract: An internal combustion two stroke engine is provided having at least one cylinder within which a piston reciprocates. The engine is joined to a gear box which includes a ring gear. A pair of gears having diameters half that of the ring gear move within the latter. At least one of said pair of gears is connected to a piston by a pin extending between the piston and the periphery of said gear. An additional pair of gears are fixed to respective ones of the first-mentioned gear pair and are operatively joined to a pinion to which a drive shaft is secured. A turbine and filter arrangement is positioned on the side of the engine opposite the gear box whereby exhaust gases from the engine are directed to the turbine to develop power at an output drive shaft joined to the turbine and to filter pollutants from the gases.

  • Patent number: 4112683
    Abstract: There is disclosed an engine which drives a turbine via a series of relatively identical hot gas pulses. The series of pulses are generated by a combustor-compressor unit under a controllable firing rate. The firing rate of the unit is rapidly variable over a wide range to enable one to drive the turbine and a shaft coupled to the turbine for propelling a vehicle. The combuster compressor is controlled to develop the gas pulses by a servo system which monitors the shaft rotation for varying mechanical loads to operate the turbine at a constant speed. A torque converter is employed to transform the shaft power into mechanical power necessary to propel a vehicle at conventional and required speed variations.

  • Patent number: 4031705
    Abstract: An auxiliary power system for an internal combustion engine. The system employs a vapor or hot gas engine coupled to an internal combustion engine by means of an overruning clutch assembly. The internal combustion engine, operated conventionally, generates heat in its cooling and exhaust systems as well as in accessory equipment. The heat generated in the internal combustion engine and its accessories is used for generating vapor in one or more heat exchangers, the vapor preferably being from a liquid with a boiling point well below that of water. The generated vapor is used to drive a vapor engine. Temperature-sensitive means is employed to measure the heat generated in one or more parts of the system for controlling a linear solenoid valve for automatically controlling the internal combustion engine temperatures and thereby the amount of vapor generated.

  • Patent number: 4003345
    Abstract: An internal combustion engine in which heat is derived from the engine cooling system and/or the exhaust to heat a working fluid in a closed circulatory system. This heat transforms the working fluid into a gas which is delivered to a turbine which drives a generator. The generator delivers DC current to an electrolysis cell in which water is decomposed. The water is decomposed by the electric current into its oxygen and hydrogen components. The oxygen is passed to the air intake of the engine carburetors, while the hydrogen is conveyed to a carburetor therefor. Also included is a carburetor for conventional hydrocarbon fuels. The two carburetors are connected by linkage which may be operated either manually or by pressure to vary the ratio of the carbureted fuels which are delivered to the engine.

  • Patent number: 3990242
    Abstract: A motor vehicle drive system in which an internal combustion engine is operatively connected to a gas turbine installation. A compressor is interposed between the engine and the turbine installation so as to receive directly the exhaust gases from the piston engine and thereby prevent the development of a back pressure upon the exhaust system.

  • Patent number: 3971218
    Abstract: The invention contemplates a protective measure for internal parts of a gas turbine, whereby foreign objects in the flow of inlet gas to the turbine are subjected to strong centrifugal action at a locally frangible region of the inlet duct, i.e., prior to turbine exposure. The material and structure of the frangible region are selected such that foreign objects of greater than predetermined mass will rupture the same and thus avoid ingestion of such objects in the gas turbine. The invention is described for the case of a turbocharger which is operated by exhaust gas from an internal-combustion engine, and which supplies compressed inlet air to the engine; upon rupture of the frangible region, a rotor-bypassing flow is established to the gas-turbine exhaust for safe handling of engine exhaust and for use in prompt development of a suitable warning.
