Abstract
A controller for an exhaust purifier performs idle-up to increase the idle speed of a diesel engine when an intake air amount, which is based on the atmospheric pressure and the engine speed, is less than a reference air amount of when a throttle valve is completely open and an EGR valve is completely closed during the regeneration of the filter. The controller performs idle-up by increasing the amount of fuel injected from the fuel injection valves of the diesel engine.
