Patent number: 7962276Abstract: The present invention relates to an internal combustion engine comprising: a plurality of combustion chambers (41,42,43,44); an air induction system (45,45A,45B,46,47) for delivering air to each combustion chamber (41,42,43,44); a fuel system for delivering fuel to each combustion chamber (41,42,43,44); an exhaust system (48,50) for relaying combusted gases from the combustion chambers (41,42,43,44) to atmosphere; and an exhaust recirculation system (49,51) to relay combusted gases from the exhaust system (48,50) to at least one of the combustion chambers (42,43). The engine has a chamber deactivation operating mode in which at least one combustion chamber (41,44) is active and receives fuel and air which are combusted therein and at least one other combustion chamber (42,43) is deactivated and is supplied with no fuel by the fuel system. In the chamber deactivation operating mode the exhaust gas recirculation system (49,51) supplies combusted gas to the (or each) deactivated combustion chamber (42,43).Type: GrantFiled: November 8, 2010Date of Patent: June 14, 2011Assignee: Lotus Cars LimitedInventors: James William Griffith Turner, Nebojsa Milovanovic

Patent number: 7934668Abstract: A fuel injector for use in an internal combustion engine, comprising a nozzle body being provided with a nozzle bore and at least one set of one or more outlets for fluid, an outer valve member received within the nozzle bore and being engageable with a first seating region of the nozzle body to control the flow of a first fluid from a first delivery chamber, the outer valve member being provided with an outer valve bore, and an inner valve member received within the outer valve bore and being engageable with a second seating region of the nozzle body to control the flow of a second fluid from a second delivery chamber. In various embodiments, the fuel injector can be arranged to allow the first and second fluids to be injected separately and/or together. In one embodiment, the first and second fluids can be mixed within the injector before injection.Type: GrantFiled: November 12, 2008Date of Patent: May 3, 2011Assignee: Delphi Technologies Holdings S.arlInventors: Michael Peter Cooke, Godfrey Greeves, Nebojsa Milovanovic

Publication number: 20070044778Abstract: With reference to FIG. 1, the present invention provides an internal combustion engine which operates repeatedly a multi-stage combustion process, the engine having a combustion chamber, supply means (12) for supplying fuel and air to the combustion chamber and exhaust means (16) for exhausting combusted gases from the combustion chamber. During a first stage of combustion (FIG. 1(a)- FIG. 1(c)) the supply means (12) supplies fuel and air to the combustion chamber and the supplied fuel and air are combusted by a spark ignition Otto process or by a compression ignition Diesel process. Then (FIG. 1(d)) at least a majority of the combusted gases resulting from the first stage combustion are retained in the-combustion chamber, additional air is supplied to the combustion chamber(FIG. 1(e)) and the resulting mixture is combusted in a second combustion stage (FIG. 1(e) and FIG. 1(f))by homogeneous charge compression ignition.Type: ApplicationFiled: August 11, 2006Publication date: March 1, 2007Inventors: Nebojsa Milovanovic, James Turner
