Abstract
A method of resuming multi-port injection using an intake stroke of an engine includes performing a first refueling with immediate start of ignition injection at the time when an injection abortion angle does not pass through an intake stroke, when injection is determined to be resumed after coasting by a controller. The method can minimize an engine RPM drop caused by the early generation of torque. The method improves fuel efficiency while being advantageous to calibration of the engine by setting the engine RPM to be low at the time of fuel cut-in.
