DEVICE AND METHOD FOR CONTINUOUSLY MEASURING THE DYNAMIC FUEL CONSUMPTION OF AN INTERNAL COMBUSTION ENGINE

摘要

In order to continuously measure the dynamic fuel consumption of an internal combustion engine having a venting tank (10) which is arranged in a feedback line (11) from the outflow side (12) of the fuel system (7) and which is also connected to the inflow line (13) to the fuel system, a filling-level regulating device (15) is provided at a port of the venting tank (10), which filling-level regulating device (15) has a circulation pump (22) and an actuating valve (9) which is connected thereto, has a continuous flow through it, and is open to a greater or lesser degree as a function of the filling level to be regulated. As a result, apparent consumption occurring in specific operating states of the internal combustion engine can be avoided or taken into account as corrections.
