More Information
Summary:The pressure in the exhaust system and in the intake system is estimated on the basis of engine speed, intake air flow, and intake air temperature. The estimation of the pressure in the exhaust system additionally takes into account (a) fuel injection volume and (b) fuel injection timing or swirl control state. The estimated pressures can be used in the control of EGR.
