economy of localities. In this system, the engine combustion is significant for power
generation. Therefore, this study mainly investigated the effect of throttle openings on the
combustion characteristics of hydrogen (H 2) and methane (CH 4) mixtures to achieve high
efficiency. Throttle opening has a strong relationship with combustion performance,
particularly for power output and efficiency. Therefore, 10%, 20%, 40%, and 100% throttle …
