摘要： A fuel supply system for an internal combustion engine, particularly of a motor vehicle, includes a control unit for determining a fuel quantity to be injected, the fuel quantity to be injected being initially increased during a start of the internal combustion engine and then being reduced again. The fuel supply system also includes a fuel injector for injecting the fuel quantity to be injected into a combustion chamber. It is checked by the control unit whether a combustion has taken place in the cylinder, and, if no combustion has taken place, the fuel quantity to be injected is not reduced, or is not reduced to the same extent as when a combustion has taken place.

摘要： A fuel delivery system for an internal combustion engine, having a fuel feed pump, which delivers fuel which is at pilot pressure to a high-pressure fuel pump that communicates on the high-pressure side with at least one injection valve, in order to deliver fuel at high pressure to the injection valve or valves. To prevent vapor bubble development in the high-pressure fuel pump, which impairs its pumping capacity and pressure generation, a coolant medium flow can be delivered to the high-pressure fuel pump via at least one coolant conduit, in order to keep the temperature (THDP) of the high-pressure fuel pump below a critical operating temperature (Tk1).

摘要： The invention relates to a method and an arrangement for calibrating a pressure sensor (7) of a fuel-metering system of an internal combustion engine wherein the fuel-metering system includes: a high-pressure pump (2) for pumping fuel from a low-pressure region (ND) into a high-pressure region (HD) injectors (5) for metering the fuel from the high-pressure region (HD) into combustion chambers (6) of the internal combustion engine with the injectors (5) being drivable in dependence upon operating characteristic variables, and the pressure sensor (7) for measuring the pressure in the high-pressure region (HD). To calibrate the pressure sensor (7) so that the offset error is minimized, it is suggested that a pressure, which is present in the high-pressure region (HD), is applied as a reference pressure; that the pressure, which is present in the high-pressure region (HD), is measured as the sensor pressure by the pressure sensor (7); and, that the characteristic line of the pressure sensor (7) is so corrected that the difference of reference pressure and sensor pressure is minimized.
