System and method for measuring injection processes in a combustion engine Precise measurements of fuel systems in terms of cycle and time while the engine is running have previously not been known or are subject to serious errors. According to the invention, a processor (26), which is connected to a device (22) disposed in a fuel line (4) for measuring temporally resolved volumetric flow processes and to the pressure sensor (14) via data transmission lines (24), is used to precisely calculate injection volumes while the engine is running. The calculation is carried out by transmitting measured values of the pressure sensor (14) on the storage container (12) and measured values of the device (22) for measuring temporally resolved volumetric flow processes in the fuel line (4) to the processor (26) using the means for capturing the actuating times to deter¬mine the actuating data, and by calculating the course of the injection of the injection valves (18) in the processor (26) by superposition of the storage contain¬er flows calculated based on the measured pressure curves of the pressure sensor (14) on the storage container (12) with the measured values of the device (22) for measuring temporally resolved volumetric flow processes in the fuel line (4). |
