Abstract
Official abstract text for this publication.
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, the engine including a turbocharger and a turbine and the exhaust manifold temperature including a temperature upstream of the turbine, the 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 the measurement.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for determining an exhaust manifold temperature in an engine, including a turbocharger and a turbine and said exhaust manifold temperature including a temperature upstream of the turbine, said method comprising: estimating a value of the exhaust manifold temperature based on an exhaust manifold temperature model including at least sensed intake manifold temperature; measuring a temperature downstream of the turbine; and correcting the valu…
