With Supercharging Means For Engine Patents (Class 60/598)
  • Patent number: 4475340
    Abstract: A power system is provided which consists of an internal combustion engine, a compressor to compress the air used in operating the engine, a pair of heat exchangers wherein the fuel for operating the engine is preheated by exhaust gases wherein the fuel is contacted indirectly, first in a low temperature zone with exhaust gas from a high temperature zone then contacted indirectly with the exhaust gases in the high temperature zone, wherein the exhaust gases are preferably boosted in velocity between the high temperature zone and the low temperature by a screw type booster fan and wherein the exhaust gases recovered from the low temperature zone are then preferably passed through one or more turbines to further recover energy.

  • Patent number: 4341070
    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).

  • Patent number: 4089173
    Abstract: A diesel engine is supercharged by a compressor driven by a turbine which receives the exhaust gas of the engine. A bypass pipe permits the air delivered by the compressor and not taken by the engine to flow to the turbine. Means for impressing to the air flow in the by-pass a pressure drop which is substantially independent of the rate of flow and increases when the output pressure of the compressor increases comprises an air balanced throttle member in the by-pass and separate control means.

  • Patent number: 4064696
    Abstract: Live-gas conduit system for turbocharged, six-cylinder, serially connected internal-combustion engines, linked between the suction inlets of the cylinders and the turbocharger, comprising two separate resonance tanks, each attached to the suction inlets of three adjoining engine cylinders, a resonance tube for each resonance tank, and a damping tank that links the inlet openings of the resonance tubes with the pressure side of the turbocharger. Special proportions and placements are suggested to attain a space-saving arrangement that reduces the space requirement, and particularly the length, of the conduit system.

  • Patent number: 4023365
    Abstract: The invention relates to an internal combustion engine having a turbine-compressor combination connected with the outlet duct for pressure filling by the thrust system; the invention has for its object to improve the shape of the high and steep peak of the exhaust pulse occurring particularly in engines having a high mean effective pressure so that the abrupt gas pulse is smoothed down so that the turbine is capable of operating with higher efficiency, and provides a combustion engine with pressure filling by the thrust system, the exhaust duct of which includes at least one restriction narrowing the passage area.

  • Patent number: 3978671
    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.

  • Patent number: 3961484
    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.
