Exhaust gas pressure estimating method for internal combustion engine e.g. diesel engine, turbine, involves estimating ratio of exhaust gas pressure in upstream and downstream of turbine, based on calculated exhaust gas weight
The method involves determining exhaust gas temperature in an upstream of a turbine. Exhaust gas flow coming out of an engine is calculated, based on air and fuel flows entering into the engine. Weight of exhaust gas in the turbine upstream is calculated based on calculated gas flow. A ratio of exhaust gas pressure in the upstream and downstream of the turbine is estimated, based on calculated weight of the exhaust gas. An independent claim is also included for a device for controlling functions of an internal combustion engine.
