Abstract
Maximum braking torque timing in an internal combustion engine can be determined by calculating the net pressure change in an engine cylinder during combustion. The second derivative of the net pressure change is then calculated. The spark timing of the engine is then varied until the maximum acceleration point of the net pressure change is aligned with top dead center.
