Patent number: 5806014Abstract: A method and system of combustion control for an internal combustion engine (313) proximate an extinction limit includes measurement of acceleration behavior of the internal combustion engine and providing a measure of combustion variability dependent thereon. Preferably, the combustion variability measure is derived by one or more stochastically based methods (607). Operation of the internal combustion engine (313) is controlled dependent on the combustion variability measurement. Fuel, ignition, and exhaust gas recirculation may all be controlled by the derived combustion variability measurement to significantly reduce hydrocarbon (HC) and NO.sub.x emissions.Type: GrantFiled: November 12, 1997Date of Patent: September 8, 1998Assignee: Motorola Inc.Inventors: Donald J.

Patent number: 5804711Abstract: A method, and a corresponding system, for determining misfire in a reciprocating engine measures engine crankshaft angular velocity and provides an angular velocity signal as measured from the engine crankshaft (403). A filtered acceleration signal, dependent on the engine crankshaft angular velocity signal and independent of normal combustion information and other high-order effects is provided via filtering (405). When the filtered acceleration signal exceeds a threshold dependent on at least one of the following; engine speed, engine load, or engine temperature (711), a misfire is indicated. Preferably, prior to the misfire determination, the filtered acceleration signal (701) is sampled over a first period of engine crankshaft rotation to provide a first data point (703), over a second period of engine crankshaft rotation to provide a second data point (707), and over a third period of engine crankshaft rotation to provide a third data point (705).Type: GrantFiled: August 6, 1996Date of Patent: September 8, 1998Inventors: Donald J.
