CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract
- This abstract for appeared for US 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 an internal combustion engine. This engine has the capability to perform both port injection and direct injection, as well as a deactivating process that stops fuel supply to certain cylinders while still supplying fuel to the remaining ones.
When the deactivating process is terminated and fuel needs to be supplied to a previously deactivated cylinder, the controller executes a retarding process. This process involves performing a first fuel injection through direct injection and delaying the start timing of the fuel injection compared to when port injection is used.
In simpler terms, the controller manages the fuel supply to an engine with different injection methods and can temporarily deactivate certain cylinders. When reactivating a deactivated cylinder, it adjusts the fuel injection timing 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.
