Abstract: A method of engine control includes: determining and comparing actual and target supply amounts of EGR gas; sensing an open rate of an EGR valve to control the actual supply amount supplied to an intake line; if the actual supply amount is smaller than the target supply amount and if the EGR-valve open rate is at a maximum, fixing an open rate of a bypass valve installed at a bypass line that bypasses an electrodynamic turbocharger to a minimum open rate; and controlling the EGR-valve open rate in a state in which the bypass-valve open rate is fixed to a minimum open rate. Therefore EGR gas can be more precisely and stably supplied.
