Abstract:
1. A start control apparatus for an internal combustion engine, comprising: a cranking actuating section to perform an energization of a starter motor in response to a request for an engine start and thereby perform a cranking of the internal combustion engine; a valve operation start control section to perform an energization of an electric variable valve motor during the cranking and thereby activate a variable valve operating mechanism to control a valve opening/closing characteristic to a condition designed to promote the cranking; and a delay control section to delay a timing of starting the energization of the electric variable valve motor from a timing of starting the energization of the starter motor at least by a predetermined delay period, to start the energization of the electric variable valve motor during the cranking to promote the cranking, after expiration of the predetermined delay period.
