Abstract
A method for controlling engine combustion may include receiving a signal of a crank position sensor, determining an angular velocity and an angular acceleration of a crank on the basis of the signal of the crank position sensor, determining a combustion characteristic index for each cylinder using the angular velocity and the angular acceleration of the crank, judging an unstable combustion cylinder using the combustion characteristic index for each cylinder, and changing a combustion factor for controlling the unstable combustion cylinder.
