A recently granted patent (Publication Number: US11927149B2) discloses a method and system for optimizing engine performance through precise fuel injection timing adjustments. The method involves adjusting injection timing during different inter-injection spacings based on previous injection times, utilizing one or more fuel injectors. Additionally, the system includes a controller with computer-readable instructions stored on non-transitory memory to facilitate learning and adjusting injection times for multiple injections during engine cycles.

Specifically, the method outlined in the patent involves adjusting injection timing based on various factors such as inter-injection spacing, pulse width, and previous injection times. The system's controller is designed to learn and adapt injection timing for multiple injections in subsequent engine cycles, ensuring optimal engine performance. By updating functions with learned injection times and spacings, the system can continuously adjust and optimize fuel injection for efficient engine operation. This innovative approach aims to enhance engine efficiency and performance by fine-tuning injection timing based on real-time data and learned parameters, ultimately leading to improved overall engine operation.
