CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE: abstract simplified (18296999)

• This abstract for appeared for patent application number 18296999 Titled 'CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE'

Simplified Explanation

The abstract describes a controller for an internal combustion engine that is designed to calculate the amount of water that collects on the intake passage's wall surface based on the temperature of the intake air. When the intake valve is open, the controller activates a water injection valve to inject water into the intake passage. Additionally, if the calculated water collection amount is below a predetermined value, the water injection valve is also activated when the intake valve is closed.

Original Abstract Submitted

A controller for an internal combustion engine is configured to calculate a water collection amount based on a temperature of intake air flowing through an intake passage, the water collection amount being an amount of water that collects on a wall surface of the intake passage, cause a water injection valve to inject water to the intake passage when an intake valve is open, and cause the water injection valve to inject water when the intake valve is closed in addition to when the intake valve is open in a case in which the water collection amount is less than a specified value that has been defined in advance.
