Method and device for assessing the quality of a fuel, in particular a diesel or petrol fuel

摘要: Fuels that are used nowadays can have a different densities or heating values. Even when filling the fuel tank ( 7 ) quality of in change since fuels mixed. For example low density value lead to reduced performance internal combustion engine 1 ). It is therefore proposed fuel-specific factor k be determined using sensor 2, 2 ), with which characteristic chamber pressure and/or lambda measured, and an algorithm. In further embodiment operating parameters (injected quantity, start injection, end injection pattern, exhaust gas recirculation rate, etc.) corrected k.
