<P>PROBLEM TO BE SOLVED: To reduce failures due to an increase in amount of EGR gas by preventing an increase in the amount of EGR gas according to an operating condition of an internal combustion engine during deceleration. <P>SOLUTION: The internal combustion engine includes: a supercharger comprising a turbine to be driven by exhaust gas energy and a compressor to be driven by the turbine to compress intake air, an intake throttle valve installed on the upstream side of the compressor, and an exhaust gas recirculating device for recirculating part of the exhaust gas to the downstream side of the intake throttle valve on the upstream side of the compressor. The method of controlling an intake throttle valve for an internal combustion engine controls the opening of the intake throttle valve according to the traveling condition of a vehicle. In the method, the operating condition of the internal combustion engine is detected, and when deceleration is determined as a result of detection, a lower limit value is set to restrict the opening of the intake throttle valve. <P>COPYRIGHT: (C)2012,JPO&INPIT |
