Cold start white smoke aftertreatment protection |
摘要 |
A method for cold start white smoke protection of a hydrocarbon after treatment device, and method of engine operation to effect the same. The method comprises a) determining the temperature of the hydrocarbon after-treatment device during cold start conditions; b) determining hydrocarbon emissions in the hydrocarbon after-treatment device; and c) modifying engine operating conditions to raise the hydrocarbon after-treatment temperature at a pre-determined rate to a temperature sufficient to permit controlled oxidation of the hydrocarbons in the hydrocarbon after treatment device. |
