Abstract
A method and a system for detecting a fuel quality in a vehicle including a first determination unit to determine a correction factor kkW for fuel as a quotient between an output fokW required to propel a vehicle and a reference output engkW which an engine in the vehicle is estimated to yield;
a secona aetermination unit to determine a correction factor kNOx for exhaust gas emissions as a quotient between a value measured in the vehicle for nitrogen oxides engNOx, and a reference value for nitrogen oxides ECUNOx;
and a detection unit to detect the fuel quality based on a relation between the correction factor kkW for fuel and the correction factor kNOx for exhaust gas emissions.
