Inlet and outlet port channel pressure estimation involves estimating inlet and outlet port channel pressure based on throttle valve position, engine speed, crankshaft angle, momentary valve motion, and combustion chamber pressure

摘要

Inlet and outlet port channel pressure is determined based on a throttle valve position, d, engine speed, R, crankshaft angle, W, and momentary valve motion, VEi and VAi and the combustion chamber pressure in i-th cylinder, Z. The measurements are provided to an estimation structure which predicts the inlet and outlet port channel pressure.
