Title:
INTERNAL COMBUSTION ENGINE DEVICE
Document Type and Number:
Japanese Patent JP2017150432
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress an increase in PN in starting-up an internal combustion engine.SOLUTION: In starting-up an engine, when cooling water temperature Tw is lower than a prescribed water temperature Twref (step S150), a throttle valve is prohibited with overshoot (step S160), and the throttle valve is controlled so that an opening degree of the throttle valve never becomes larger than a target throttle opening degree Ttag even once but becomes the target throttle opening degree Ttag (step S170, S180). Thus, an increase in PN is suppressed.SELECTED DRAWING: Figure 3
