摘要： Alcohol fuel conversion apparatus for internal combustion engines including a fuel tank, a fuel pump, a primary heat exchanger, a heat source, a converter and a carburetor or fuel injection system. The pump delivers pressurized liquid alcohol to the primary heat exchanger where the alcohol fuel is heated above the vaporization point at ambient pressure. The heated fuel is next delivered to the carburetor where the vaporized alcohol is metered and mixed with air for proper combustion and then delivered to the intake system of a conventional internal combustion engine, or, alternately, by means of the fuel injection system, the fuel is delivered directly to the cylinders where it is mixed with air for proper combustion. A fuel pre-heater assembly utilizing waste heat from the engine may also be provided.

摘要： An air-fuel ratio control system for an internal combustion engine, including an oxygen concentration sensor producing an output signal whose level is substantially proportional to an oxygen concentration of the exhaust gas, effects a feedback control of the air-fuel ratio of mixture to be supplied to the engine toward a target value determined on the basis of various parameters of the engine operation and corrected in response to a magnitude of atmospheric pressure, so that the target air-fuel ratio is made lean as the magnitude of the atmospheric pressure decreases. Thus, the reduction of the engine output power and the increase of the fuel comsumption which have been encountered in conventional systems are prevented.

摘要： A process and device for determining the composition of an alcohol-petrol mixture supplying a combustion engine. According to this process a light beam is emitted through the mixture supplying the engine, the degree to which this beam is absorbed by the mixture is determined in a wave length chosen in the wave length range corresponding to the near infra-red and adjustment of the operating parameters of the engine is controlled as a function of the degree of absorption thus measured.

摘要： To start an ethanol fueled engine at low temperatures, a valve directs liquid ethanol from the carburetor accelerator pump to a PTC thermistor grid disposed in the engine induction passage below the throttle. The electric grid evaporates the liquid ethanol to provide sufficient ethanol vapor to start the engine and then is deenergized when the engine has started.

摘要： In addition to the gasoline-air mixing primary carburetor on an internal combustion engine, an auxiliary carburetor is provided for mixing air and alcohol, to thereby provide a substantial portion of the fuel-air mixture used by the engine during idle conditions and light-load conditions, while the primary carburetor provides an increasingly greater portion of the total fuel-air mixture during high-load conditions. The alcohol fuel-air mixture flows directly to the intake manifold, thus by-passing the throttle valve which controls the fuel-air mixture from the primary carburetor. The auxiliary carburetor is vacuum controlled.

摘要： The system fundamentarily consists of a means to prepare a substantially gaseous mixture of a fuel, e.g., hydrocarbons, oxygen and water, a heated catalyst chamber and a reciprocating compressor. The compressor is arranged and valve-controlled such that the fuel mixture is pressurized before the feeding into the catalyst chamber and the heated and pressurized H.sub.2 -containing mixture is drawn into and expanded in the working chamber of the compressor before the feeding into an engine. The means to prepare the starting fuel mixture may include a sub-system for producing oxygen and water from hydrogen peroxide.

摘要： An internal combustion engine is equipped with a water injector for cooling the internal combustion engine by a spray of atomized water into the intake track or combustion chamber prior to ignition. The atomized water spray may be in the intake manifold or directly in the cylinder. The water is injected at a volume of between a ratio of about 95% fuel to about 5% water and about 50% fuel and about 50% water. The temperature of the internal combustion engine is maintained at between about 95° C. and about 200° C. during operation.
