摘要： An article of manufacture and method are provided to determine pressure in an unfired cylinder of an internal combustion engine. The cylinder comprises a variable volume combustion chamber defined by a piston reciprocating within a cylinder between top-dead center and bottom-dead center points and an intake valve and an exhaust valve controlled during repetitive, sequential exhaust, intake, compression and expansion strokes of said piston. The code is executed to determine volume of the combustion chamber, and determine positions of the intake and exhaust valves. A parametric value for cylinder pressure is determined at each valve transition. Cylinder pressure is estimated based upon the combustion chamber volume, positions of the intake and exhaust valves, and the cylinder pressure at the most recently occurring valve transition.
