Title: Fuel Injector For An Internal Combustion Engine
Inventor: Jean-François Berlemont
IPC: F02M65/00
Filed: 2018-01-31
Abstract: A fuel injector for an internal combustion engine is disclosed. The injector is characterised by a detection circuit 64 for monitoring the position of both an injection needle 14 and a valve member 28 of a control valve 20. The circuit includes first and second circuit branches 64.1, 64.2, connected at one end to a common detection voltage terminal 66. The first leg 64.1 switches to closed when the needle rests on its seat 42 and has a first predetermined resistance value R1. The second leg 64.2 is configured to be complete when the valve member 28 rests on its seat 26. The second circuit branch has a predetermined impedance value R2 which is different to that of the first circuit branch. The two circuit branches may be in parallel, such that the circuit takes four different resistance values depending on the status of the needle and valve member. The configuration means only one terminal wire and detection circuit is needed to monitor both valves.

Title: EGR urea hydrolysis
Inventor: JEREMY GIDNEY
IPC: F02M26/30
Filed: 2018-03-28
Abstract: An exhaust system for an internal combustion engine comprises an exhaust gas recirculation (EGR) circuit 12, 14 that connects an exhaust stream to an intake of the engine. A surface 18 of a heat exchanger 10 in the EGR circuit comprises a urea hydrolysis catalyst. A urea injector 16 provides urea to the surface of the urea hydrolysis catalyst. The resulting ammonia 20 is introduced to the exhaust stream. The EGR circuit may be low pressure or high pressure. The ammonia may be introduced upstream of a selective catalytic reduction (SCR) catalyst, which may be loaded on the same substrate as a downstream ammonia oxidation catalyst. There may be a particulate filter. A surface of the heat exchanger that is contacted by the exhaust stream may be catalytically coated to discourage soot accumulation. A lean burn internal combustion engine, i.e. a compression ignition engine, comprises the exhaust system. The heat from the EGR circuit assists the conversion of urea to ammonia.

Title: Method and system for operating instances of a game
Inventor: SERGUEI BOURENKOV
IPC: G07F17/32
Filed: 2012-02-10
Abstract: A computer-implemented method of and system for operating instances of a game having a plurality of game positions that can be occupied by players, such as table positions in an internet poker-type game. The method comprises associating with a player a plurality of weights relating to respective game positions, where each weight is indicative of a respective bias towards placement of the player at the respective game position. The placing of a player at a particular position can be based upon a bias measure calculated from the position weighting information associated with the player and wait time. Each of the plurality of weights is updated after the first game provide an altered bias towards placement at each respective position. The player is then assigned to a second game instance based on a bias measure for each game position in dependence on the player weight for the given game position and a time value related to the time that the player has been waiting or idling. The second game can be started if the player folds out-of-turn in the first game. The invention avoids unfair advantages or disadvantages in games where player position is important, such as Texas Hold ‘Em poker.
