  • Engine valve actuation for combustion enhancement
    Patent number: 7337763
    Abstract: A combustion chamber valve, such as an intake valve or an exhaust valve, is briefly opened during the compression and/or power strokes of a 4-strokes combustion cycle in an internal combustion engine (in particular, a diesel or CI engine). The brief opening may (1) enhance mixing withing the combustion chamber, allowing more complete oxidation of particulates to decrease engine emissions; and/or may (2) delay ignition until a more desirable time, potentially allowing a means of timing ignition in otherwise difficult-to-control conditions, e.g., in HCCI (Homogeneous Charge Compression Ignition) conditions.
    Type: Grant
    Filed: January 16, 2004
    Date of Patent: March 4, 2008
    Assignee: Wisconsin Alumni Research Foundation
