    摘要: A method of correlating a rotational position of a crankshaft to a rotational position of a camshaft includes determining a stretch value of a timing connection, which drivingly couples the crankshaft and the camshaft, and calculating a crankshaft to camshaft rotational position value indicative of the rotational position of the crankshaft with respect to the rotational position of the camshaft. The crankshaft to camshaft rotational position value is compensated based on the stretch value to provide a compensated crankshaft to camshaft rotational position value and whether the rotational position of the crankshaft correlates to the rotational position of the camshaft is determined based on the compensated crankshaft to camshaft rotational position value.

    摘要: An engine control system for a vehicle includes a variable displacement module that deactivates N of M cylinders of an engine during a fuel management mode. N is an integer and M is an integer greater than 1. A spark control module generates a spark timing signal for the N cylinders based on a pre-dwell time and a fuel management dwell modifier during the fuel management mode. The spark control module reduces dwell time of the N cylinders during the fuel management mode based on the fuel management dwell modifier.
