Publication number: 20100089364Abstract: A method and apparatus for providing automatic pressure balancing of an internal combustion engine. The engine includes cylinders, fuel injector valves provided to selectively deliver fuel directly into the cylinders, fuel-balancing valves each fluidly connected to the fuel injector valves for controlling the fuel delivered to the fuel injector valves and cylinder pressure sensors each mounted to one of the cylinders. The method comprises an automatic pressure balancing procedure including the steps of monitoring a cylinder pressure in each of the cylinders, determining a peak combustion pressure produced in each of the cylinders, calculating a mean peak pressure produced in all of the cylinders, calculating a pressure difference between the mean and the peak pressure and incrementally adjusting the fuel delivered by one of the fuel-balancing valves to the corresponding fuel injector valve mounted to the cylinder having the pressure difference larger than a predetermined pressure value.Type: ApplicationFiled: October 2, 2009Publication date: April 15, 2010Inventors: Edward FLANAGAN, Steve Follmar, William Griffith

Patent number: 7370630Abstract: The present invention relates (with reference to FIG. 1) to an internal combustion engine in which a combustion chamber (12) can be connected to a reservoir (16) for storing compressed air. Gas flow control valve means (15) controls flow between the chamber (12) and reservoir (16) so that air pressurised in the chamber (12) can be relayed to charge the reservoir (16) and pressurised air can be delivered to the chamber (12) to drive piston (10). The chamber (12) is also used for combustion of fuel. The invention also relates to a valve mechanism for controlling the flow of pressurised air between the chamber (12) and reservoir (16), in which a balancing force is applied to the gas flow control valve (115) to cancel the force on the valve (115) arising from the pressure applied to the back face of the valve (115).Type: GrantFiled: May 28, 2004Date of Patent: May 13, 2008Assignee: Lotus Cars LimitedInventors: James William Griffith Turner, Jeffrey Allen

Patent number: 7204102Abstract: A method of forming an air-tight scal between two pieces of glass is described. It comprises the steps of: (a) introducing a layer of indium or indium alloy between opposing surfaces of the glass pieces; and (b) heating the indium or indium alloy layers and the glass pieces, preferably under vacuum, to a temperature, generally around or below 220° C., to melt the layers to form the seal between the pieces. The method is suitable to form a relatively small air-type seal between two glass panes or sheets, and is particularly suitable for the formation of evacuated double glazing units. Optionally, an additional metal layer is located between the indium or indium alloy layers.Type: GrantFiled: April 17, 2000Date of Patent: April 17, 2007Assignee: University of UlsterInventors: Philip Charles Eames, Brian Norton, Philip William Griffiths, Trevor James Hyde
