摘要： Methods and systems for low emission power generation in hydrocarbon recovery processes are provided. One system includes a gas turbine system configured to stoichiometrically combust a compressed oxidant derived from enriched air and a fuel in the presence of a compressed recycle exhaust gas and expand the discharge in an expander to generate a recycle exhaust stream and drive a main compressor. A boost compressor receives and increases the pressure of the recycle exhaust stream and prior to being compressed in a compressor configured to generate the compressed recycle exhaust gas. To promote the stoichiometric combustion of the fuel and increase the CO2 content in the recycle exhaust gas, the enriched air can have an increased oxygen concentration.

摘要： The invention is intended to provide improved emission-cleaning performance by use of a three-way catalyst alone, without the need for a lean NOx catalyst, while ensuring a fuel economy improvement effect of lean burn operation. A multicylinder spark-ignition engine is constructed such that, in a pair of preceding and following cylinders whose exhaust and intake strokes overlap each other, burned gas discharged from the preceding cylinder (2A, 2D) which is currently in the exhaust stroke is introduced directly into the following cylinder (2B, 2C) which is currently in the intake stroke through an intercylinder gas channel (22) and gas discharged from only the following cylinder (2B, 2C) is led to an exhaust passage (20) provided with a three-way catalyst (24) in a low-load, low-speed operating range. Fuel supply to the individual cylinders is controlled in such a manner that combustion in the preceding cylinder (2A, 2D) is made under lean mixture conditions at an air-fuel ratio larger than the stoichiometric air-fuel ratio by a specific amount and combustion in the following cylinder (2B, 2C) is made under conditions of the stoichiometric air-fuel ratio created by supplying fuel to the burned gas introduced from the preceding cylinder (2A, 2D).

摘要： A device designed to use exhaust gas discharged out of an engine combustion chamber by dissociating chemical substances contained in the exhaust gas such as CO, CO.sub.2, NOx, HC, etc., in an exhaust gas molecule dissociating tube and drawing components of the exhaust gas, oxygen in particular, again into the engine combustion chamber. The device is so constructed as to collect dust including the carbon component of the exhaust gas in a cyclone drum for removal from the exhaust gas, which allows all of the engine exhaust to be recycled without releasing it in the atmosphere. The device is utilizable with various engines, e.g., gasoline engines, diesel engines and so on, and well-suited to mass production on account of its simple, compact and lightweight construction.

摘要： In a working gas circulation engine, water vapor contained in exhaust gas after combustion is separated and removed at higher efficiency as compared with the conventional technology, the influence of remaining water vapor is prevented from reducing the ratio of specific heats of working gas and deteriorating the thermal efficiency of the engine. A working gas circulation engine which comprises a circulation passage part which connects an inlet port communicated to a combustion chamber and an exhaust port communicated to the combustion chamber in the exterior of the combustion chamber, supplies fuel, oxygen, and working gas to the combustion chamber to burn the fuel in the combustion chamber, and supplies the working gas contained in the exhaust gas discharged through the exhaust port from the combustion chamber to the combustion chamber through the circulation passage part and the inlet port. The working gas circulation engine comprises a water vapor condensing means which interposes in said circulation passage part and has an entrance part and an exit part, the water vapor condensing means removes water vapor from gas flowing thereinto through the entrance part from said circulation passage part by condensing water vapor contained in the gas and discharges the gas from the exit part to said circulation passage part, a gas pressure detecting means to detect the pressure of the gas flowing into said water vapor condensing means, and a gas pressure adjusting means to adjust the pressure detected by said gas pressure detecting means.

摘要： PROBLEM TO BE SOLVED: To improve fuel economy by lean combustion, especially on a low load side or during idling. SOLUTION: In a pair of cylinders where an exhaust stroke and a suction stroke overlap, burned gas emitted from preceding cylinders 2A, 2D in the exhaust stroke side is made to be directly introduced to subsequent cylinders 2B, 2C on the suction stroke side through a gas passage 22 between the cylinders and only the gas emitted from the subsequent cylinders 2B, 2C is led to an exhaust passage 20. Especially during low load and idling, combustion is performed with a super lean air-fuel ratio which is three times or more of a stoichiometric air-fuel ratio in the preceding cylinders 2A, 2D, and in the subsequent cylinders 2B, 2C, fuel is supplied to the burned gas introduced from the preceding cylinders 2A, 2D and combustion by forced ignition as an actual stoichiometric air-fuel ratio is performed. Accompanying an increase in the load, combustion by compressed self-ignition is performed in the subsequent cylinders 2B, 2C. COPYRIGHT: (C)2004,JPO
