Abstract: A variable turbocharger and a control method thereof are provided to improve output by preventing turbo lag phenomenon in low speed and securing the inflow section of exhaust gas in the high speed. A variable turbocharger comprises a turbine housing(310), a first scroll(314), a second scroll(316), a cut-out part, and a flow control valve(320). The first scroll is formed within the turbine housing. The exhaust gas passes through the turbine(312) and is flowed out. The second scroll is formed around the first scroll along the first scroll. The cut-out part changeably separates the first scroll and the second scroll. The flow control valve changeably blocks the exhaust gas flowed into the second scroll.

Abstract: PURPOSE: A method for controlling an engine for a vehicle is provided to make the closing time of an intake valve different even under low load while keeping high-speed maximum horsepower with a flow-centered intake port in an engine freely controlling motions of an intake and exhaust valve. CONSTITUTION: If starting of an engine is on, the rotational frequency of the engine and load are inputted(S100,S110). The engine includes a cylinder equipped with two intake valves and two exhaust valves. In the fixed map table, the opening and closing time of the intake and exhaust valves is set up and inputted. The opening time of the appropriate primary and secondary intake valve and the opening and closing time of the primary and secondary exhaust valve are set up(S120,S130). Load state of the engine is decided(S140). The control of the engine is performed by setting up the closing time of the primary and secondary intake valve different depending on the loading state of the engine(S150,S160). Therefore, combustion stability of the engine is improved and exhaust gas is reduced.
