Title:
METHOD FOR CONTROLLING EXHAUST GAS TEMPERATURE AND SPACE VELOCITY
Document Type and Number:
WIPO Patent Application WO2004061273
Kind Code:
A8
Abstract:
A method for controlling the temperature and/or space velocity of exhaust gas provides control of the maximum temperature of the exhaust gas to prevent thermal damage to the Diesel engine components and associated aftertreatment devices during regeneration of the aftertreatment devices. The method includes controlling intake and/or exhaust valve opening timing and duration, either singly or in combination with selective individual cylinder cutout, in response to sensed engine operating parameters.
