CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18193702 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. The engine can perform both multi-shot injection (injecting fuel multiple times during each combustion cycle) and single-shot injection (injecting fuel only once per cycle). Additionally, the engine can deactivate certain cylinders by stopping the fuel supply to them while still supplying fuel to the remaining cylinders.
When the deactivation process is being terminated and fuel needs to be supplied again to a deactivated cylinder, the controller initiates a retarding process. This process involves performing a single-shot fuel injection, but with a delayed start timing compared to when the engine is operating in multi-shot injection mode.
In simpler terms, the controller manages the fuel supply to an engine with multiple cylinders. It can deactivate some cylinders temporarily, and when reactivating them, it 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 may execute multi-shot injection and single-shot injection and 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 single-shot injection and retards a fuel injection start timing as compared to when executing the multi-shot injection.
