The process involves controlling recirculated exhaust gas flow according to one of the following data such as a pressure (P2mes) in an inlet end casing (18), a pressure (P3mes) in the upstream of a turbine of a turbocharger (12), and a temperature (T3estim...

The process involves measuring flow of fresh air to an internal combustion engine (1) and pressure and temperature of gas intake by engine. The flow of fresh air is controlled based on an instruction by modulating a rate of recycled gas exiting the engine....

The device has a temperature sensor placed in the flow of an exhaust gas in upstream of a turbine between the turbine and an exhaust manifold. The sensor measures temperature of the gas before the gas enters into the turbine. A controller (41) receives a t...

An engine control system (5) is configured to improve the estimation accuracy of a fresh intake air quantity and a total intake air quantity that flows into the combustion chambers (19). The engine control system (5) is configured to estimate an estimated ...

A control system and method for an EGR valve (54), particularly in a diesel engine (30). A processor processes data in feedback control of the position of the valve element to develop from the data a position control signal for setting the extent to which ...

A processor provides feedback control of the exhaust gas recirculation valve based upon the actual position of the valve and its desired position. The processor generates error signals from the position data and from the actual EGR flow and the desired flo...

The method involves computing the pressure between first and second components in succession in the air path for induction air from the sum of the air mass flows into and out of the first and second components. The first and second components determine the...

Sensors (11) measure the temperature, pressure and mass flow of air admitted (9) to a diesel engine which receives fuel from injectors (7) and the air from an exhaust driven turbocompressor (4). During any post injection fuel/air supply on the expansion st...

A first target drive force is computed based on the operation amount of an accelerator pedal, and dynamic delay processing is applied to the first target drive force to calculate a second target drive force. A target engine fresh air intake amount is compu...
