ABSTRACT:
A method of evaluating a contribution of a cylinder to an engine includes measuring a first revolutions per minute of the engine during an enabled state; determining a dwell period of the cylinder; applying a direct current voltage signal into a negative terminal of an ignition coil of the engine during the dwell period to disable the cylinder and create a disabled state; and measuring a second revolutions per minute of the engine during the disabled state. A system for evaluating a contribution of a cylinder to an engine includes a first measure module, a determine module, an apply module, and a second measure module. The first measure module measures a first revolutions per minute of the engine during an enabled state. The determine module determines a dwell period of the cylinder. The apply module applies a direct current voltage signal into a negative terminal of an ignition coil of the engine during the dwell period to disable the cylinder and create a disabled state. The second measure module measures a second revolutions per minute of the engine during the disabled state.
