  • Engine exhaust particulate after-treatment system
    Patent number: 7021050
    Abstract: An exhaust particulate trapping means 12 for trapping particulates in exhaust gases is provided in an exhaust path 3 of an engine. When the engine enters a deceleration condition during the removal by burning of exhaust particulates trapped by the exhaust particulate trapping means 12, the drop of the flow rate of exhaust gases flowing into the exhaust particulate trapping means 12 is restricted. Thus, the cooling action of the exhaust particulate trapping means 12 through heat exchange with the exhaust gases can be kept up to suppress that the temperature of the exhaust particulate trapping means 12 excessively rises on engine deceleration.
    Type: Grant

    Date of Patent: April 4, 2006
    Assignee: Mazda Motor Corporation
