METHOD FOR ESTIMATING EXHAUST MANIFOLD PRESSURE |
摘要 |
A method is provided for estimating a pressure in an exhaust manifold of an internal combustion engine, the internal combustion engine having a combustion chamber with an associated exhaust valve, the method includes, but is not limited to acquiring pressure values within the combustion chamber during an acquisition period (AP) chosen within the time interval when the exhaust valve is open, and averaging the pressure values to obtain a single pressure value which is representative for the pressure in the exhaust manifold.
