    • Reformer-enhanced alcohol engine system. The engine system includes a spark-ignited alcohol engine having a compression ratio in the range of 13-15 and includes a turbo charger or supercharger operatively connected to the engine to provide a pressure boost of at least about 2.5 times atmospheric pressure to cylinders of the engine. A source of alcohol is provided for injection into the engine. A reformer is provided including a low-temperature reforming catalyst in a heat transfer relation with exhaust gas from the engine and arranged to receive alcohol from the alcohol source for reforming the alcohol into a hydrogen-rich gas. Means are provided for injecting the hydrogen-rich gas into the engine and a knock sensor detects knock in the engine. A fuel management control unit is provided which is responsive to the knock sensor to apportion the ratio of alcohol injected into the engine to hydrogen-rich gas injected into the engine. The engine of the invention can provide a 15-25% efficiency gain in a methanol-fueled spark ignition engine relative to a diesel engine in a typical drive cycle.

    • The invention relates to the technology of hydrocarbon processing and more particularly to the production of synthesis gas from gaseous hydrocarbon raw.
      The object of the present invention is to provide an improved method for producing synthesis gas, which includes combustion of the mixture of raw hydrocarbons and air at α = 0.5 ÷ 0.8 and oxidation of hydrocarbons upon compression stroke of the piston in the cylinders of the modified internal combustion engine, expansion and cooling of the products during the piston stroke to the bottom dead center, output of the products containing synthesis gas from the reaction volume upon the piston stroke to the top dead center, inlet of a new portion of the working mixture upon the piston stroke to the bottom dead center differing by that a mixture of raw hydrocarbons with air preheated to 200 - 450°C is fed into the cylinders of the modified internal combustion engine, and the mixture is compressed until self-ignition takes place and a temperature of 1300 - 2300°C is maintained over a time period of 10 -2 - 10 -3 s, and the cycle being repeated with a frequency exceeding 350 min -1 .
      In frameworks of this method, the use of methane, ethane, and other gaseous hydrocarbons as the raw materials obtained, in particular, through separation of the broad fraction of light hydrocarbons from the associated gases makes it possible to improve the ecological situation in the regions of oil production and processing. The specific productivity of the method is ∼ 2.5 times higher compared to the known method.
