METHOD AND OBSERVER FOR DETERMINING THE EXHAUST MANIFOLD TEMPERATURE IN A TURBOCHARGED ENGINE

摘要

The disclosure relates to a method and an observer for determining the exhaust manifold temperature in a turbocharged engine upstream of the turbine. In one example, a method for determining an exhaust manifold temperature in a turbocharged engine, said engine including a turbocharger and a turbine and said exhaust manifold temperature including a temperature upstream of the turbine, said method comprises estimating a value of the exhaust manifold temperature based on a model, measuring a temperature downstream of the turbine, and correcting the value of the exhaust manifold temperature based on said measurement.
