In an attempt to regenerate energy of exhaust gas by using a pressure regenerator secured to an exhaust port of a displacement type engine so as to realize the Atkinson's cycle, if the engine is a four-cycle engine, raising regenerative pressure may cause abnormal fuel combustion or melting damage of an exhaust valve. The present invention has successfully solved this problem by using a six-cycle engine. The six-cycle engine with a regenerator according to the present invention is capable of varying proportion of the power output that is generated by the six-cycle engine itself and that is generated by the regenerator. Using this principle enables the six-cycle engine with a generator to be used as an engine that is capable of generating two kinds of output power or as a six-cycle gas turbine with high controllability. The invented internal combustion engine is excellent and valuable in the fuel cost economy when it is used as a motor for a power station and a small generator as well as a motor for a movable body such as a ship or a vehicle. The invented internal combustion engine is especially suitable for a movable body such as a hybrid-system vehicle. Incidentally, the inventor is ready for granting the rights for practicing the present invention.

The nozzles include inlet ports circumferentially arranged into a group and an opening and closing valve disposed so as to be commonly functioned. This arrangement realizes a gas turbine with no deterioration of efficiency against fluctuation of gas inflow rate by only one heat-resistant moving component additionally installed. The variable nozzle number turbine according to this invention also realizes a turbine compressor with no surge limit when used as a regenerator. These turbines further realizes a small-sized gas turbine with improved fuel economy under partial load conditions and a turbocharger for regenerating electric power as well as improving efficiency of a displacement engine.
摘要:
A gas turbine generally exhibits a substantial deterioration in efficiency against fluctuation of gas flow rate. A variable nozzle turbine is a solution for this disadvantage; however, it has also another disadvantage of low efficiency under partial load conditions and a large number of heat-resistant moving components. A variable nozzle number turbine according to this invention overcomes these disadvantages. The turbine includes nozzles for injecting gas to rotor blades. The nozzles include inlet ports circumferentially arranged so as to be grouped into a group and an opening and closing valve disposed thereover so as to be commonly functioned therefore. This arrangement realizes a gas turbine with no deterioration of efficiency against fluctuation of gas inflow rate by only one heat-resistant moving component additionally installed. The variable nozzle number turbine according to this invention also realizes a turbine compressor with no surge limit when used as a regenerator. These turbines further realizes a small-sized gas turbine with improved fuel economy under partial load conditions and a turbocharger for regenerating electric power as well as improving efficiency of a displacement engine used therewith. It is to be noted that the inventor is ready for grant of working license.

摘要:
A six-cycle engine has the advantage for the capability of internal cooling with scavenging air. This advantage enables the compressive ratio to rise, thereby achieving lower fuel consumption. However, there has been a critical problem due to lowered temperature of the exhaust catalyst and excessive volume of oxygen contained therein caused by the mixing of the scavenging air with exhaust gas. To solve the problem of lowered temperature, the invention has thermally insulated the fuel combustion chamber and the exhausting system, and controlled the aperture degree of the scavenging port valve relatively to the suction valve to adjust the scavenging air volume against the suction air, thereby controlling temperature of the exhaust gas. Further, to solve the problem of excessive volume of oxygen, the invention has introduced an EGR (Exhaust Gas Recirculation) system to fully substitute the scavenging air with circulating exhaust gas and a self EGR system to open the exhaust valve during the scavenging air introduction stroke. The present invention has successfully made a naturally good fuel-efficient six-cycle internal combustion engine be suited one for practical use such as conventional vehicles.
