Publication number: 20090320807Abstract: The present invention provides a system for providing hydrogen gas to inject into the intake of an internal combustion engine. A hydrogen storage reservoir in communication with the gas output port stores a supply of hydrogen, and a hydrogen storage release valve retains the hydrogen in the storage reservoir and selectively releases hydrogen from the storage reservoir when the engine is started. In the preferred embodiment the system comprises an electrolysis cell that produces hydrogen when the engine is warm, and hydrogen is released from the storage reservoir when the system is active but the electrolysis cell is not producing hydrogen.Type: ApplicationFiled: March 5, 2007Publication date: December 31, 2009Applicant: MARTINREA INTERNATIONAL INC.Inventors: Zdenek Cerny, Francis Michael Burke

Publication number: 20090301407Abstract: The present invention provides a system for providing electrolyte to an electrolysis cell for producing hydrogen gas to inject into the intake of an internal combustion engine. The system includes an electrolysis cell having an electrolyte input port, an electrolyte output port and at least one working gas output port. The electrolyte output port communicates with a storage reservoir. A coolant liquid conduit is in thermal communication with the electrolyte solution and in fluid communication with a portion of the engine coolant system in which the coolant liquid has been heated by the engine when the engine is running. To heat up the electrolyte solution and improve the efficiency of electrolysis, the heated liquid coolant is diverted from the engine coolant system and circulated through the heating system to transfer heat to the liquid containing the electrolyte.Type: ApplicationFiled: March 5, 2007Publication date: December 10, 2009Applicant: MARTINREA INTERNATIONAL INC.Inventors: Zdenek Cerny, Francis Michael Burke

Patent number: 6394252Abstract: An electromagnetically actuated power transmitting assembly has a cup shaped pulley structure mounted for rotation about the input shaft of a power driven device. The pulley structure has an outer annular driven portion for engaging an endless flexible driving element such that engine driven movement of the driving element rotates the pulley structure. The outer annular portion has ferromagnetic material along at least an internal diametrical periphery thereof to allow magnetic flux to flow therethrough. A one-piece flux carrier/mounting structure is formed from ferromagnetic material and has a mounting portion fixedly mounted to the power driven device and an annular flux carrier portion nested within the cup shaped pulley structure to allow the pulley structure to rotate relative to the flux carrier and to allow magnetic flux to flow therebetween. An annular magnetic coil for inducing a field of magnetic flux is fixedly mounted in the carrier portion.Type: GrantFiled: October 18, 2000Date of Patent: May 28, 2002Assignee: Tesma International Inc.Inventors: Zdenek Cerny, Ryszard Ostrowski, Peter Depikolozvane, Norman Cerny

Patent number: 5575728Abstract: A drive assembly for rotating a shaft of a pulley driven device. The drive assembly includes a hub in the form of an annular body of ferrous metal having a groove in an external periphery thereof. A belt driven pulley is provided in the form of ferrous sheet metal and has a web portion. A structural connection is defined between the hub and the pulley web portion such that the hub is in fixed, abutted relation with the pulley web portion. The hub and the pulley web portion have a bore therethrough defining a single, machined annular surface. The annular surface is constructed and arranged to engage a periphery of the shaft in an interference-fitted manner so as to maintain torque transfer to the shaft in the event of failure of the structural connection. The groove is constructed and arranged to be operatively engaged by a pulling tool for removing the annular surface from engagement with the shaft.Type: GrantFiled: March 29, 1995Date of Patent: November 19, 1996Assignee: Tesma International, Inc.Inventor: Zdenek Cerny
