Abstract:
A turbocharged engine system (500) is configured to vaporize methanolin a heat exchanger (350) using heat from exhaust gases, and uses the vaporized methanol to drive a turbine (361) of the engine's turbocharger (316, 519,124, 126). The methanol may also be dissociated into hydrogen and carbon monoxide. After passing through turbine (316), the vapor is injected into the engine (102) by port injection. By selective timing of exhaust valves (472, 474), the exhaust gases are separated into two streams (409, 410), a first stream comprising gases ejected during exhaust blowdown, and a second stream of gases ejected during the remainder of the engine's exhaust stroke. The blowdown gases are employed to drive a separate turbine (519) of the turbocharger (316, 519, 124, 126).

Abstract:
The present invention is a fuel vaporizer that will greatly increase power and economy in fuel powered engines while producing far less pollution. The present invention has a fuel chamber, air inlet and heating element that aerate fuel while vibrating and heating the fuel from a liquid to a more combustible gaseous vapor.
Abstract:
A hybrid fuel vaporization system and an apparatus for producing power from a source of liquid fuel. The hybrid fuel vaporizing system comprises: (a) at least one capillary flow passage, said at least one capillary flow passage having an inlet end and an outlet end, said inlet end in fluid communication with the source of liquid fuel; (b) a heat source arranged along said at least one capillary flow passage, said heat source operable to heat the liquid fuel in said at least one capillary flow passage to a level sufficient to change at least a portion thereof from a liquid state to a vapor state; and (c) a vaporizing member having a first surface and a second surface, said first surface exposed to heat produced by the apparatus for combusting fuel, said vaporizing member positioned so that fuel exiting said outlet end of said at least one capillary flow passage impinges on said second surface whereby a stream of substantially vaporized fuel is delivered for combustion.
Abstract:
This invention relates to a fuel vaporisation device 10. The vaporisation device 10 which includes a chamber 12, a fuel inlet 20 and a fuel outlet 24. The wall 14 of the chamber 12 is heated by a heating jacket 28. In use, the device may be attached to an internal combustion engine. Air containing entrailed fuel droplets enter into the device 10 via the inlet 20. A vortex formed within the device 10 forces fuel droplets to impinge with the heated side wall 14 which vaporises the fuel. A fuel vapour air mixture exits the device via the outlet pipe 24. The vaporised fuel-air mixture is then conveniently supplied to the inlet manifold of the internal combustion engine, to improve the performance of the engine.

Abstract:
Liquid fuel vapourisation apparatus (20) including: first pressure reduction means (43, 44) for receiving liquid fuel and reducing its pressure to a first controlled pressure to vapourise at least some of the fuel; a vapouriser (50) in fluid communication with the first pressure reduction means (43, 44) for receiving the partly vapourised fuel and vapourising the remainder of the liquid fuel to provide a gaseous fuel; a second pressure reduction means (47, 48) in fluid communication with the vapouriser (50) for receiving the gaseous fuel and reducing its pressure thereof to a second controlled pressure for delivery (17) to one or more of the fuel injectors of an internal combustion engine. The first and second pressure reduction means (43, 44, 47, 48) are either operatively interposed between the throttle body and the intake manifold of the engine or operatively incorporated into a throttle body.
Abstract:
The invention relates to a fuel supply installation for an internal combustion engine, comprising a fuel tank (2) for liquid fuel (3), a fuel pump (5) which induces fuel from the fuel tank (2), subjects said fuel to an injection pressure and makes it available to the internal combustion engine, a fuel fractionating unit (9) which creates at least one liquid fraction from the fuel and comprising an accumulator (35) which receives the liquid fuel fraction from the fuel fractionating unit (9), stores the same and makes it available to the internal combustion engine. The fuel supply installation supplies the available fuel fraction and the available fuel to the internal combustion engine as and when required. In order for the fuel fraction and the fuel to be made available to the internal combustion engine at the same pressure, the accumulator (35) is configured as a pressure accumulator, whereby pressure generating elements (5, 48, 15) are provided which are used to subject the fuel fraction in the pressure accumulator to the injection pressure.
Abstract:
A combustion improving method capable of efficiently enhancing fuel efficiencies of petroleum fuels and a device therefor. A combustion method using petroleum fuels, such as gasoline, light oil, heavy oil, wherein a fuel to be supplied from a fuel tank to a combustion chamber is heated to temperatures within a preset range and supplied to the chamber in a partially vaporized condition. An improvement effect generally increases with an increase in heating temperature; a temperature at which at least part of fuel vaporizes is preferable although heating to 30 DEG C gives some improvement. Any heating source is used as a heating means; specifically, in the case of engines, fuel refluxed from a combustion chamber to a fuel tank is directly circulated to a fuel supply pipe, and, in the case of boilers and heavy-oil burners, a fuel supply pipeline is routed through a boiler steam flow path, or through or in the vicinity of combustion chamber fuel flames, whereby an excellent effect can be obtained with simple changes in existing facilities.
