Abstract

A low emission, internal combustion compression ignition engine having a cylinder, a piston movable in the cylinder and a pre-combustion chamber communicating with the cylinder near the top thereof and in which low emissions of NO.sub.x are achieved by constructing the pre-combustion chamber to have a volume of between 70% and 85% of the combined pre-chamber and main combustion chamber volume when the piston is at top dead center and by variably controlling the initiation of fuel injection into the pre-combustion chamber.

Nitrogen enriched combustion of a natural gas internal combustion engine to reduce NO.sub.x emissions

Patent Biruduganti, Munidhar S [Naperville, IL]; Gupta, Sreenath Borra [Naperville, IL]; Sekar, R Raj [Naperville, IL]; ...

A method and system for reducing nitrous oxide emissions from an internal combustion engine. An input gas stream of natural gas includes a nitrogen gas enrichment which reduces nitrous oxide emissions. In addition ignition timing for gas combustion is advanced to improve FCE while maintaining lower nitrous oxide emissions.

Apparatus for photocatalytic destruction of internal combustion engine emissions during cold start

Patent Janata, Jiri [Richland, WA]; McVay, Gary L [Richland, WA]; Peden, Charles H [West Richland, WA]; ...

A method and apparatus for the destruction of emissions from an internal combustion engine wherein a substrate coated with TiO.sub.2 is exposed to a light source in the exhaust system of an internal combustion engine thereby catalyzing oxidation/reduction reactions between gaseous hydrocarbons, carbon monoxide, nitrogen oxides and oxygen in the exhaust of the internal combustion engine.

Process for in-situ production of hydrogen (H2) by alcohol decomposition for emission reduction from internal combustion engines

Patent Anderson, Kenneth B.; Carrado-Gregar, Kathleen; Marshall, Christopher L.; ...

A process and apparatus are provided for in-situ production of hydrogen (H.sub.2) by alcohol decomposition for emission reduction from internal combustion engines. Hydrogen is generated by a catalytic process for in-situ production from alcohols, either neat, or in a hydrocarbon mixture, such as gasoline. The in-situ production of hydrogen is achieved using a solid basic catalytic bed provided with the internal combustion engine. The preferred catalyst is a copper (Cu) containing layered double hydroxide (LDH)-derived catalyst, such as a Cu/Al LDH-derived catalyst. At least a portion of an alcohol containing fuel is passed through the catalyst bed to generate hydrogenmore »« less

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.

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
