Abstract
An oxidation catalyst temperature control system and method for an engine having an exhaust means including an oxidation catalyst is provided. A post fuel calculation means calculates a value representing a post quantity of fuel to be introduced to generate an exothermic reaction in the oxidation catalyst based on a pre-determined desired outlet temperature of the oxidation catalyst, the calculation using a steady state model of the oxidation catalyst, the steady state model utilizing the exhaust mass flow rate and the inlet temperature of the oxidation catalyst and instruction means to instruct the post quantity of fuel to be introduced to the engine.
