Title:
INTERNAL COMBUSTION ENGINE CYLINDER-TO-CYLINDER BALANCING
Document Type and Number:
WIPO Patent Application WO2005028845
Kind Code:
A3
Abstract:
A method of balancing combustion among cylinders of an internal combustion engine. For each cylinder, a normalized peak firing pressure is calculated as the ratio of its peak firing pressure to its combustion pressure. Each cylinder's normalized peak firing pressure is compared to a target value for normalized peak firing pressure. The fuel flow is adjusted to any cylinder whose normalized peak firing pressure is not substantially equal to the target value.
