A mechanism exists for determining the percentage of time an engine’s fuel injectors are actively delivering fuel during each engine cycle. This calculation provides insight into the operational stress and capacity of the fuel injection system. For instance, a reading of 80% indicates the injector is open and spraying fuel for 80% of the duration available during each engine revolution.
Understanding fuel injector usage is paramount for engine tuning and optimization. Maintaining injectors within appropriate operating parameters prevents potential damage and ensures consistent engine performance. Historically, this calculation was performed manually, requiring precise measurement of injector pulse width and engine speed. Modern methodologies automate this process, enhancing accuracy and efficiency.
