Two-Cycle Stratified Charge Gas Engine
US Patent:
4445467, May 1, 1984
Filed:
Aug 10, 1982
Appl. No.:
6/406826
Inventors:
Howard G. Westerman - Richardson TX
Lewis E. Allsopp - Stafford, GB2
Lewis E. Allsopp - Stafford, GB2
International Classification:
F02B 2300, F02B 7502
US Classification:
123 65R
Abstract:
A two-cycle, gas-powered engine which is capable of operating over a wide range of loads including those (e. g. idle speed) which have previously caused misfirings in known engines of this type. A specially constructed head and piston assembly and a governor-controlled fuel system are incorporated into an otherwise typical two-cycle engine to convert the engine into a stratified charge engine. The head and piston assembly is constructed to provide an ovate-domed, flat-bottomed combustion chamber therebetween when the piston is in a top dead center position in the cylinder. This combustion chamber allows fuel injected in the top of the combustion chamber to mix with air being compressed by the piston to provide a rich stratified charge around the ignition means (e. g. spark plugs) which are also positioned near the top of the chamber. This charge is always rich enough to support rapid ignition and to quickly spread burning to the weaker, exhaust-contaminated mixture present in the lower combustion chamber.
Compressor With Suction Valve In Piston
US Patent:
5658134, Aug 19, 1997
Filed:
Jul 26, 1995
Appl. No.:
8/507765
Inventors:
James J. Gagnon - Carrollton TX
Howard G. Westerman - Richardson TX
Paul H. Bergthold - Longview TX
Howard G. Westerman - Richardson TX
Paul H. Bergthold - Longview TX
Assignee:
J-Operating Company - Dallas TX
International Classification:
F04B 300, F04B 2500
US Classification:
417262
Abstract:
A compressor which provides for minimum clearance in the compression chamber while substantially reducing the heat normally experienced by the piston during the compression stroke of a compressor of this type. The suction valve(s) of the compressor is concentrically mounted in the piston while the discharge valve(s) is concentrically mounted in a stationary position within the cylinder. Since the high heat of compression occurs at the discharge valve, the piston will be much cooler than in prior art compressors of this type which improves the efficiency of the compressor and which substantially extends the operational life of the piston rings.
