摘要：
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 degrees BTDC, 18 degrees BTDC, 21 degrees BTDC and 24 degrees BTDC) with fixed coolant temperature (90 degrees C +/- 2 degrees C). the results showed that advancing the static ignition time with CNG from 15 degrees BTDC to 24 degrees 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.
