20100012753 | FUEL INJECTOR FOR AN INTERNAL COMBUSTION ENGINE - A fuel injector comprising an injector body having a spray aperture; a pintle extending within the injector body for axial movement between a closed position and an open position; said pintle head comprising a tapered portion engageable against the valve seat of the spray aperture and a cylindrical portion upstream of said tapered portion, an annular channel being provided defining a first part of a flow passage upstream of the spray aperture, wherein a discontinuity is provided downstream of the annular channel and upstream of the spray aperture to generate cavitation when the pintle stroke exceeds a predetermined limit to thereby generate a virtual channel of constant cross section downstream of the annular channel whereby the flow rate of the fuel flowing through said spray aperture is substantially independent of the stroke of the pintle when the pintle is in its open position. | 01-21-2010 |

20150068494 | METHOD OF CONTROLLING AN INJECTION TIME OF A FUEL INJECTOR - A method of controlling fuel injection in an internal combustion engine is presented. A drive signal is generated for each injection event, with which the injector is kept open to spray fuel in accordance with a requested fuel quantity. The drive signal has a duration based on a pulse width that is determined from an injector-specific correspondence function defining the pulse width vs. a corresponding open time variable representative of injector open time. The open time variable is determined on the basis of a master performance function defining the requested fuel quantity in function of the open time variable. | 03-12-2015 |

20090166107 | POWER TRANSMISSION METHOD - The invention concerns a power transmission method using a transmission device receiving mechanical power from several sources, comprising at least first and second electrical machines, and delivering the power to an output shaft. The method consists in decoupling the first electrical machine from a first input point of the device, then in coupling the first electrical machine to a second input point of the device. The method is characterized in that it consists in, when the first electrical machine is being decoupled, compensating the power (P | 07-02-2009 |
