To provide an effective technology to efficiently perform a regeneration of the collection part collecting particulate while suppressing fuel consumption as much as possible in an exhaust emission control device mounted on an engine for an industrial vehicle.
The exhaust emission control device 100 performs purification processing of exhaust gas emitted from a diesel engine 10 of a fork lift. It is possible to efficiently raise the temperature of the exhaust gas by using a fuel injection amount adjustment part 20, an engine load adjustment part 30, an intake throttle adjustment part 40, and a fuel injection timing adjustment part 28 in order to process regeneration of the collection part 14 under a predetermined temperature condition. The temperature of the exhaust gas can be set to be a predetermined temperature condition to improve the fuel consumption for regeneration processing of the collection part 14, while keeping engine revolutions and engine load low.
