ABSTRACT:
An engine ECU executes a program comprising the steps of: calculating a post-warm-up steady-state port wall deposit quantity (a); calculating a shared-injection steady-state port wall deposit quantity (b) based on port wall deposit quantity (a); calculating a difference (c) in one cycle of shared-injection steady-state port wall deposit quantity (b); making a correction considering an engine temperature and an engine speed to calculate a transition correction quantity (d); and converting transition correction quantity (d) into a wave form representing temporal transition to make a wall deposit correction with higher priority on a port injection quantity.
