Due to internationally significant differences in fuel ingredients and the resulting fuel quality, modern direct injection gasoline and diesel engines need to be able to adapt their point of optimal operation according to the used type off fuel. This is necessary to achieve optimum fuel efficiency, exhaust gas minimization and protection of exhaust gas after-treatment components. Therefore it is important to understand at least minimal qualitative properties of the fuel in the car‘s tank. In future fuel scenarios and emissions regulation standards this is no longer possible with software based virtual sensors based on lambda and knock-sensor read-out only, because the control is delayed.
