Air intake system operating method for e.g. diesel engine of motor vehicle, involves changing from exhaust manifold pressure regulation state to intake manifold pressure regulation state, when absolute value becomes less than threshold
Air intake system operating method for e.g. diesel engine of motor vehicle, involves changing from exhaust manifold pressure regulation state to intake manifold pressure regulation state, when absolute value becomes less than threshold
The method involves sequentially regulating pressure in an intake manifold (120) and pressure in an exhaust manifold (122) of an internal combustion engine (110). A state of regulation of pressure in the exhaust manifold is changed to a state of regulation of pressure in the intake manifold, when an absolute value of difference between a set point pressure in the intake manifold and the pressure determined in the intake manifold becomes less than a threshold. Independent claims are also included for the following: (1) a computer readable data acquisition medium comprising a computer program with a set of instructions for implementing an intake system operating method (2) an intake system of an internal combustion engine, comprising hardware and/or software units for implementing an intake system operating method.
