    摘要: A combustion control system for a vehicle comprises a pressure ratio (PR) module, a pressure ratio difference (PRD) module, and a pressure ratio difference rate (PRDR) module. The PR module determines fired PR values and measured motored PR values based on cylinder pressures measured by a cylinder pressure sensor when a cylinder of an engine is fired and motored, respectively. The PRD module determines PRD values for predetermined crankshaft angles, wherein each of the PRD values is determined based on one of the fired PR values and one of the measured motored PR values at one of the predetermined crankshaft angles. The PRDR module determines and outputs a PRDR value based on a rate of change of the PRD values over a range of the predetermined crankshaft angles.
