Method and apparatus for calculating the actual fuel amount injected in a combustion chamber of an internal combustion engine

摘要

The method involves determining, preferably measuring, the flow speed or pressure pulsations of the fuel in a medium connection (3) between a high pressure generator and at least one injector or an injection nozzle of a fuel injection system. The fuel throughput in the medium connection is derived from the determined flow speed or pressure pulsations AN Independent claim is also included for the following: an arrangement for determining the actual fuel quantity injected into an internal combustion engine combustion chamber.
