Abstract
The use of a crankshaft flywheel speed sensor for closed loop control of internal combustion engines is described. Speed variations due to cycle-to-cycle and cylinder-to-cylinder combustion variations are sensed and used to control fuel quantity and combustion timing in engines with electronic control systems. Some potential uses of the speed variation measurement for engine diagnostics are described.
