To provide a supercharging type engine capable of improving acceleration responsiveness by improving turbo lug in a simple constitution where opening and closing timing of an existing intake/exhaust valve is adjusted.
The supercharging type engine comprises a supercharger 22 for supercharging intake air by driving a turbine 24 and a compressor 23 by exhaust stream of the engine 1, a variable valve timing mechanism 13 for changing valve overlap by altering opening/closing timing of at least one of an intake valve 7 and an exhaust valve 9 of the engine, and an electronic control unit 12 for controlling the variable valve timing mechanism 13 with an acceleration request detecting section for detecting an acceleration request of a driver. When the acceleration request detecting section detects the acceleration request of the driver, the electronic control unit 12 controls the variable valve timing mechanism 13 to enlarge the valve overlap.
