CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE: abstract simplified (18194534)

• This abstract for appeared for patent application number 18194534 Titled 'CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE'

Simplified Explanation

The abstract describes a controller that is designed to control the operation of an internal combustion engine. This engine has the capability to perform both port injection and direct injection, as well as a process called deactivation, which stops fuel supply to certain cylinders while supplying fuel to the remaining ones.

When the deactivation process is terminated and fuel needs to be supplied to a previously deactivated cylinder, the controller initiates a retarding process. This process involves injecting fuel directly into the cylinder using direct injection, but with a delayed start timing compared to when port injection is used.

In simpler terms, the controller is responsible for managing the fuel supply in an engine that can switch between different injection methods and deactivate certain cylinders. When reactivating a deactivated cylinder, the controller adjusts the timing of the fuel injection to ensure smooth operation.

Original Abstract Submitted

A controller is configured to control an internal combustion engine. The internal combustion engine can execute port injection and direct injection and can execute a deactivating process that stops supplying fuel to at least one of cylinders and supplies fuel to the remaining cylinders. The controller is configured to execute, when terminating the deactivating process to restart supplying fuel to a deactivated cylinder in which supply of fuel is stopped, a retarding process that executes a first fuel injection through the direct injection and retards a fuel injection start timing as compared to when executing the port injection.
