METHODS AND SYSTEMS FOR AN EXHAUST GAS RECIRCULATION SYSTEM
Methods and systems are provided for a high-pressure exhaust gas recirculation system. In one example, the high-pressure exhaust gas recirculation system comprises pressure seconds arranged on different sides of a valve. The pressure sensors are used to regulate exhaust-gas recirculate flow without a fixed orifice delta pressure sensor.

Method to determine the mass of air trapped in each cylinder of an internal combustion engine
A method to determine the mass of air trapped in each cylinder of an internal combustion engine, which comprises determining, based on a model using measured and/or estimated physical quantities, a value for a first group of reference quantities; determining, based on the model, the actual inner volume of each cylinder as a function of the speed of rotation of the internal combustion engine and of the closing delay angle of the intake valve; and calculating the mass of air trapped in each cylinder as a function of the first group of reference quantities and of the actual inner volume of each cylinder.

Method and system for rationalizing a temperature within an engine system
Systems and methods for determining whether or not a temperature sensor is degraded are presented. In one example, a determination of degradation of the temperature sensor is based on a difference between a temperature determined from output of the temperature sensor and an estimate of a temperature of a pressure sensor.
