WebDec 5, 2024 · Conclusion. AGMA and ISO gear ratings can be executed with load spectra (duty cycles)—based on Miner’s rule—as explained in ISO 6336-6 (Ref. 1). Load spectra may be defined by different methods. In this paper, the ability to generate a duty cycle from a time series (time-torque-speed data) is explained. If the valve is pulsed ON at variable durations (called pulse-width modulation), the duty cycle varies. If it is pulsed ON for 0.05 seconds in a 0.1-second cycle, the fuel injector duty cycle equals 50%. If it pulsed ON for 0.09 seconds of that same 0.1-second cycle, the fuel injector duty cycle equals 90%. See more In an automotive electronic fuel injection system, voltage pulses supplied to the fuel injector valve solenoid control the fuel injector valve at a … See more Pulse width is a measure of the actual ON time, measured in milliseconds.
