Abstract
A system for controlling an engine includes a driving information detector detecting driving information. At least one intake valve and at least one exhaust valve open and close the combustion chamber. A variable valve lift (VVL) system adjusts opening timing of the intake valve and the exhaust valve. A compressor rotates by a rotational force of a turbine and compresses intake air, and a vane adjusts the amount of exhaust gas supplied to the turbine. A controller controls opening of the vane using a high pressure EGR valve, when the exhaust valve is open during a suction stroke by the VVL system, the vehicle accelerates or decelerates, and an air/fuel ratio is beyond reference ratio range.
