20160090101 | SPARK CONTROL SYSTEMS AND METHODS FOR ENGINE TORQUE ESTIMATION - A spark control module, for an engine speed and an engine load: for a first predetermined period, supplies spark to each cylinder of the engine at a predetermined spark timing set for the engine speed and the engine load. For a second period following the first predetermined period, the spark control module: provides spark to a first one of the cylinders at a first spark timing that is retarded relative to the predetermined spark timing; and supplies spark to all of the other cylinders of the engine at the predetermined spark timing. The storage module selectively stores in memory: a first torque output of the engine measured during the first predetermined period; and a second torque output of the engine measured during the second period. | 03-31-2016 |
