Abstract
A system for an engine includes first, second, third, and fourth modules. The first module determines an expected response of crankshaft speed due to combustion within a cylinder of the engine. The second module determines a value based on the expected response and a measured response of crankshaft speed due to combustion within the cylinder of the engine. The third module estimates an indicated mean effective pressure (IMEP) for the cylinder of the engine based on the value. The fourth module selectively adjusts an operating parameter of the engine based in the estimated IMEP.
