Title: Method and apparatus for determining a normal combustion characteristic for an internal combustion engine from an accelerometer signal

Abstract

The method comprises operating a calibration engine, and collecting combustion characteristic data and reference accelerometer signals, which are correlated with each other and stored in a calibration table. The calibration table can be used by an engine to determine a real-time normal combustion characteristic when the engine is operating by collecting a real-time accelerometer sensor signal and cross correlating with the correlated data stored in the calibration table. Accordingly, the apparatus comprises a calibration engine comprising a calibration sensor, a reference accelerometer sensor and a data storage device for storing the collected calibration data that is correlated with the collected reference accelerometer signals, and an engine equipped with an accelerometer sensor, a calibration table and an electronic engine controller programmed to receive real-time accelerometer signals and cross correlate them with reference accelerometer signals to determine a real-time normal combustion characteristic.

Method and apparatus for using an accelerometer signal to detect misfiring in an internal combustion engine

Patent Huang, Jian; Cheung, Duran; Mumford, David

The method comprises operating an engine and collecting a real-time accelerometer signal from an accelerometer sensor. The real-time accelerometer signal is digitized and filtered to isolate data in a frequency range associated with combustion to produce a filtered signal data set. The filtered signal data set is integrated to produce an integrated signal data set, and misfire is detected by comparing the integrated signal data set with a predetermined reference data set associated with the same operating point. The apparatus is a control system for an engine that comprises an accelerometer sensor mounted to the engine; a look-up table inmore » « less

An apparatus and method for utilizing any arbitrary mixture ratio of multiple fuel gases having differing combustion characteristics, such as natural gas and hydrogen gas, within an internal combustion engine. The gaseous fuel composition ratio is first sensed, such as by thermal conductivity, infrared signature, sound propagation speed, or equivalent mixture differentiation mechanisms and combinations thereof which are utilized as input(s) to a "multiple map" engine control module which modulates selected operating parameters of the engine, such as fuel injection and ignition timing, in response to the proportions of fuel gases available so that the engine operates correctly and atmore » « less

An internal combustion engine starting apparatus uses a signal from a curt sensor to determine when the engine is energized and the starter motor should be de-energized. One embodiment comprises a transmitter, receiver, computer processing unit, current sensor and relays to energize a starter motor and subsequently de-energize the same when the engine is running. Another embodiment comprises a switch, current transducer, low-pass filter, gain/comparator, relay and a plurality of switches to energize and de-energize a starter motor. Both embodiments contain an indicator lamp or speaker which alerts an operator as to whether a successful engine start has been achieved.more » « less
