Popis: | In this paper, studying the effects of static spark time on the performance and emissions of a spark ignition engine using compressed natural gas. Engine performance and emissions were measured repeatedly at different static ignition time (15° BTDC, 18° BTDC, 21° BTDC and 24° BTDC) with fixed coolant temperature (90°C± 2°C). the results showed that advancing the static ignition time with CNG from 15° BTDC to 24° BTDC at the full load increased the brake power, brake torque, brake thermal efficiency and hydrocarbon by 4.07%, 4.67%, 3.58% and 4.89% respectively, while carbon monoxide and volumetric efficiency doesn’t change effectively at the full and half load conditions. |
