Abstract:
A system and method is disclosed to increase the efficient of internal combustion engines where the system and method converts a portion of thermal energy produced in the combustion process to a usable form of energy. If the engines are used in power generation, then the system and method increases the power output of the engine significantly. If the engines are used in traditional mechanical operations such as ships, then the system and method operates to increase mechanical power output or to increase co-produced electrical energy output.

Abstract:
In a turbocharger equipped with a motor/generator, the motor/generator gradually decreases its generator output without shifting abruptly from generation mode to motor mode when a vehicle starts accelerating during cruising at a constant speed or runs along an upward slope, thus preventing abrupt increases in the loading on an engine. A control system for a motor/generator equipped turbocharger which is disposed across an exhaust conduit of an engine and includes a rotating shaft thereof on which a motor/generator is mounted is provided having a controller for, when the motor/generator is actuated as a motor, feeding the motor/generator with a supply of power from a battery, and when the motor/generator is actuated as a generator, converting an alternating current, high voltage form for charging the battery and also to a three-phase alternating current form for driving as a motor an alternator which is driven as a generator by the engine, an engine revolution sensor, an accelerator opening sensor, and an engine boost pressure sensor. More specifically, the control system comprises a calculating device for calculating a target boost pressure from the engine revolution sensor and the accelerator opening sensor, a first judging device for determining that the action of the engine is an acceleration mode when a difference between the target boost pressure and an actual boost pressure is smaller than a first predetermined value, and a device for decreasing the generator output of the motor/generator when the motor/generator is actuated as the generator during the acceleration mode judged by the first judging device.
Abstract:

Abstract:
An exhaust gas turbine powered electric generating system for supplying electrical loads on a motor vehicle. The inlet of the gas turbine is supplied with the exhaust gas of an internal combustion engine. The effective turbine inlet area is controlled by a valve which is adjusted as a function of the output current of the generator. As generator output current increases the valve is adjusted to decrease turbine inlet area thereby increasing engine back pressure which tends to slow the engine down. An idle speed control is provided which in response to engine slow-down increases the amount of air and fuel supplied to the engine to thereby increase the exhaust gas mass flow supplied to the turbine.
Abstract:
Disclosed is a type of an exhaust gas energy recovery method for an internal combustion engine of a type which incorporates a turbine generator driven by the exhaust gas energy of the internal combustion engine and in which the driving power of a motor driven by the power generated by the generator is added to the driving power of the internal combustion engine. The method also incorporates a control device for controlling the output torque of the motor in different forms at low and high speed areas within a variable control range of the rotation speed of the internal combustion engine. The motor is operated with constant torque characteristics at the low speed area and with reduced torque characteristics at the high speed area thereby enabling the exhaust gas energy to be efficiently recovered at an engine speed area where the ratio of engine-operating time is high.
Abstract:
An engine which utilizes gas and compressed air to provide propulsive force. A compressor and a turbo are connected to the engine to provide compressed air for driving the engine to either supplement or replace the gas.
Abstract:
An internal combustion engine includes an annular or ring-type cylinder and piston therein; exhaust ports from the cylinder lead to an afterburner reactor situated generally medially of the annular cylinder; the exhaust gases are further burned within the afterburner section; to further reduce pollutants during the afterburning process, additional air is pumped into the afterburner section as by the ring piston due to its special configuration enabling it to accomplish, for example, triple functions such as: (a) to act as a power transmitting means, (b) to act as a pumping means to supply the engine's combustion chamber with scavenging air and/or an air-fuel mixture, and (c) to act as an air pumping means to supply desired quantities of ambient air into the afterburner section even in timed intervals with a constant predetermined pressure and predetermined quantities in order to thereby maximize the degree of control of the temperature generated in the afterburner and thereby more nearly fully oxidize the unburned fuel residues entering the afterburner. The ring piston is so constructed that it can be operatively connected to an output shaft as through the use of only a single crank, single connecting rod and wrist pin. Further, to extract a considerable amount of energy from the waste exhaust gases leaving the afterburner, a power turbine is provided which is within the exit path of the exhaust gases. The power turbine is conveniently incorporated as into the engine head and the turbine output shaft is either geared by reduction gear means to work in unison with the output crank shaft, or the turbine shaft rotates at an independent speed and is geared to drive (some or all of) the engine and/or vehicular accessories.
