Internal combustion engine control method

Title: Internal combustion engine control method

Abstract

A method for controlling an internal combustion engine having a plurality of cylinders including a first cylinder and one or more remaining cylinders includes selecting a desired auto-ignition dwell for a first combustion cycle for the first cylinder of the plurality of cylinders. A first fuel mass is provided to the first cylinder which is combusted during the first combustion cycle. An actual auto-ignition dwell for the first combustion cycle which results from the first fuel mass is determined and a dwell error is calculated. The dwell error is used to determine a second fuel mass which provided to the first cylinder and which is combusted during the second combustion cycle.

Method and device for diagnosing and controlling combustion instabilities in internal combustion engines operating in or transitioning to homogeneous charge combustion ignition mode

Patent Wagner, Robert M [Knoxville, TN]; Daw, Charles S [Knoxville, TN]; Green, Johney B [Knoxville, TN]; ...

This invention is a method of achieving stable, optimal mixtures of HCCI and SI in practical gasoline internal combustion engines comprising the steps of: characterizing the combustion process based on combustion process measurements, determining the ratio of conventional and HCCI combustion, determining the trajectory (sequence) of states for consecutive combustion processes, and determining subsequent combustion process modifications using said information to steer the engine combustion toward desired behavior.

Internal combustion engine and method for control

Patent Brennan, Daniel G

In one exemplary embodiment of the invention an internal combustion engine includes a piston disposed in a cylinder, a valve configured to control flow of air into the cylinder and an actuator coupled to the valve to control a position of the valve. The internal combustion engine also includes a controller coupled to the actuator, wherein the controller is configured to close the valve when an uncontrolled condition for the internal engine is determined.

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

Patent Huang, Jian; Ancimer, Richard; Cheung, Duran

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 collectedmore »« less

System and method for conditioning intake air to an internal combustion engine

Patent Sellnau, Mark C.

A system for conditioning the intake air to an internal combustion engine includes a means to boost the pressure of the intake air to the engine and a liquid cooled charge air cooler disposed between the output of the boost means and the charge air intake of the engine. Valves in the coolant system can be actuated so as to define a first configuration in which engine cooling is performed by coolant circulating in a first coolant loop at one temperature, and charge air cooling is performed by coolant flowing in a second coolant loop at a lower temperature.

Patent Heffel, James W.; Scott, Paul B.; Park, Chan Seung

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
