The present invention will be problems to provide an engine that can activate a catalyst of an exhaust purifying apparatus during low-temperature start-up. Engine 101 of the present invention, and an engine body having a plurality of cylinders (6a~6f), and a fuel injector 14 for injecting fuel into the respective cylinders (6a~6f), the exhaust of the engine body having a controller 50, which provided in the path and the exhaust emission control apparatus having an oxidation catalyst (31), adjusting the fuel injection amount and fuel injection timing by the fuel injection device 14, and the controller 50 is a low temperature in gamtong (減 筒) engine 101 for performing the operation of the rest of fuel injection for a specific cylinder (6a~6c) at the time of startup, the controller 50, while when the gamtong operation during cold-start, It performs the post injection (post-injection) to inject the fuel at least once after a top dead center of the first combustion cycle of the operating cylinder for the cylinder (6d~6f) of tissue other than the specific cylinder the fuel injection.
