  • Patent number: 8713939
    Abstract: In a case of a refrigerant amount being short when a Rankine cycle starts operating, because the pressure difference does not occur across a refrigerant pump, refrigerant cannot be injected from a bypass circuit to the Rankine cycle, and therefore super-cooling degree cannot be controlled. An exhaust heat recovery system is provided that can adjust the super-cooling degree even in the case of the pressure difference not occurring across the refrigerant pump. The system includes a refrigerant tank, for storing refrigerant, which is connected by pipes to the low-pressure circuit side and the high-pressure circuit side of the Rankine cycle through a low-pressure-side valve and a high-pressure-side valve, respectively, and a temperature adjuster for adjusting internal temperature of the refrigerant tank.

  • Patent number: 8434307
    Abstract: A system and method for recovering energy from gases of an internal combustion engine in conjunction with exhaust gas recirculation is described and illustrated, and in some embodiments includes an exhaust gas recirculation valve and an exhaust gas recirculation heat exchanger, with a working medium which undergoes a cyclic process being evaporated in the exhaust gas recirculation heat exchanger by hot exhaust gases, and with resulting steam being converted into mechanical or electrical energy which is available as additional energy. To improve heat recovery with little technical expenditure, an exhaust gas control valve can interact with the exhaust gas recirculation heat exchanger, and can control the mass flow of exhaust gases flowing through the exhaust gas recirculation heat exchanger constantly in all operating phases of the internal combustion engine, approximately in the vicinity of the performance limit of energy recovery.

  • Publication number: 20090031933
    Abstract: Carbon dioxide in combustion exhaust gas can be effectively separated and the combustion exhaust gas including the other exhaust gas components condensed through the separation of carbon dioxide can be discharged to the atmosphere. Air 7 is separated by an air separation unit 8 into oxygen 9 and other nitrogen-prevailing gas 10a. The obtained oxygen 9 and coal 1 are burned by a burner 5a of a combustion furnace 4. Exhaust gas treatment is conducted for the resultant combustion exhaust gas from the furnace 4. Then, part of the combustion exhaust gas is recirculated to the burner 5a and the remaining unrecirculated combustion exhaust gas is compressed to take out liquefied carbon dioxide 29. The other exhaust gas components 31 unliquefied through the compression is mixed and diluted with the other nitrogen-prevailing gas 10a in the separation of the oxygen 9 from the air 7 in the air separation unit 8 and is discharged to the atmosphere.

  • Patent number: 7104063
    Abstract: The invention relates to a device for producing mechanical energy. Said device contains an internal combustion engine and an expansion engine (20, 21) which is fed with superheated steam from a steam generator. Exhaust gases of the internal combustion engine are injected into the steam generator (24) to use the waste heat thereof. In order to eliminate pollutants and non-burned fuel in the exhaust gases of the internal combustion engine in a simple and effective manner, the steam generator (24) is heated by a non-catalytic burner (16) at a burner temperature of between 1100° and 1300° C. The exhaust gases of the internal combustion engine can be combined with the combustion gases in the burner (16). The after-burning of non-burned fuel and the combustion of pollutants is thus carried out in a burner (16) in a non-catalytic manner.

  • Patent number: 6810668
    Abstract: In order to control an actual temperature of a vapor generated by en evaporator (3) for heating water by an exhaust gas from an engine (1) to a target vapor temperature by varying the amount of water supplied from a supplied-water amount control injector (7), a control unit (11) controls the amount of water supplied in a feedforward manner in accordance to an engine rotational speed and an intake negative pressure and controls the amount of water supplied in a feedback manner based on a difference between the actual vapor temperature and the target vapor temperature. It is possible to control the actual temperature of the vapor generated by the evaporator (3) to the target vapor temperature with a high accuracy even in a transient state of the engine (1) by correcting a feedforward control value using at least one of a fuel-cut control signal, an ignition-retarding control signal, an EGR control signal and an air fuel ratio control signal which are parameters indicating a burned state of the engine (1).

  • Patent number: 6694737
    Abstract: A compensation system for a vehicle has a main reservoir, a vapor collector, an expansion tube, a working liquid supplying reservoir and an oil tank. The main reservoir is connected with the vapor collector via a heat absorbing pipe. The expansion tube is connected to the vapor collector. Two turbines are rotatably received in the expansion tube and are connected to a generator. The supplying reservoir is connected to the expansion tube. The oil tank encloses the expansion tube and absorbs the heat of the waste gas dissipated from the engine. Accordingly, the turbines will be actuated to rotate by means of expansion of volume of the working liquid sprayed into the expansion tube to actuate the generator to operate. The waste heat dissipated from the engine of the vehicle can be efficiently reused.

  • Publication number: 20020002827
    Abstract: A low or no pollution engine is provided for delivering power for vehicles or other power applications. The engine has an air inlet which collects air from a surrounding environment. At least a portion of the nitrogen in the air is removed using a technique such as liquefaction, pressure swing adsorption or membrane based air separation. The remaining air is primarily oxygen, which is then compressed and routed to a gas generator. The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen containing fuel, such as hydrogen or methane. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide with carbon containing fuels. Water is also delivered into the gas generator to control a temperature of the combustion products. The combustion products are then expanded through a power generating device, such as a turbine or piston expander to deliver output power for operation of a vehicle or other power uses.

  • Patent number: 4599863
    Abstract: A compound engine having at least one internal combustion cylinder operating in a conventional manner, and an air or external combustion cylinder associated therewith. The external combustion cylinder operates according to the same cycle as the internal combustion cylinder, namely through consecutive intake, compression, expansion and exhaust strokes of the piston associated therewith. The charge taken by the external combustion engine is not fired and is caused to expand by transferring the heat of the exhaust gases from the internal combustion cylinder to the charge in the external combustion cylinder, at the end of the compression cycle thereof, so as to cause the gaseous fluid charge therein to expand to apply motive power to a driven output common to both the internal combustion cylinder and the external combustion cylinder.

  • Patent number: 4026115
    Abstract: A power plant comprises an internal combustion engine, (Diesel engine), a compressor for supercharging the engine and a turbine for driving the compressor. The turbine is fed in parallel by the exhaust conduit of the engine and by a passage communicating with the compressor outlet. The passage is divided into two parallel arms. The first arm has a throttle. The second arm is connected to the primary zone of an auxiliary combustion chamber via orifices of a cross-section such that the pressure drop produced between the upstream and downstream ends of the orifices of the second arm is the same as the pressure drop produced between the upstream and downstream ends of the throttle of the first arm. The combustion chamber is fed by a fuel supply system entering the primary zone in the region of the turbulence produced in this zone by the arrival of air through the orifices, so that a complete and stable combustion is achieved in the auxiliary combustion chamber.
