Abstract: The internal combustion engine performs the thermodynamic cycle partially inside the cylinder, with the piston connected to the crankshaft, and partially in a turbo blower in which there takes place the final stage of the expansion of the burnt gases and, simultaneously, the suction and the first phase of compression of the air. The said compression is completed afterwards in the cylinder, continuously and without any partialization.

Abstract: An internal combustion engine apparatus and method of operation includes the monitoring of the exhaust gas temperature and air-fuel ratio on a continuing basis. The exhaust gas temperature is compared to a stored value and compression of the input air is varied to cause the exhaust gas temperature to equal the stored value. By minimizing the exhaust gas temperature increased engine efficiency can be realized. The invention may be embodied in a variety of engine configurations, including piston and turbine systems.

Abstract: A method of performing work and an apparatus for performing the method utilizing the following thermodynamic cycle. Ambient air is isothermally compressed to a predetermined degree (A-B) and then heat is added to the air at constant pressure (B-C). This is followed by isentropic compression (C-D) which in turn is followed by heat addition at constant volume (D-E). Thereafter follows isentropic expansion (E-F-H-G) then finally heat recovery (G-A). The recovered heat (G-A) is preferably utilized for the initial heat addition (B-C).

Abstract: A dual air-oil separator which separates two air-oil mixtures of differing proportions in a single unit having first and second chambers for the separate mixtures. The two chambers are separated by a perforated partition wall. The air-oil mixture, high in air is separated as it passes from the first chamber through the perforated wall and into the second chamber. The second chamber directly receives the air-oil mixture, low in air, for separation and combination in its sump with the oil from the first chamber.

Abstract: Greater overall power is obtained from an internal combustion engine utilizing a power recovery turbine operated by the exhaust gases from the engine cylinders by dimensioning the stacks connecting the exhaust valve flow areas to the turbine such that each stack has a cross sectional flow area less than the cross sectional flow area of the exhaust valve when fully opened. While there results a slight increase in frictional losses in the stack and pumping losses to the piston, such losses are more than made up by the substantial decreases in throttling losses across the exhaust valve flow area during the valve opening process.
