Abstract

Abstract: In our previous studies, a plasma reformer system has been developed to produce syngas containing hydrogen to an electronic fuel injection motorcycle engine. In present investigation, the effect of ignition timing of the engine was considered with an improved spark plug reformer system. The spark plug reformer system included two spark plugs, three supersonic atomizers, a controlling device, and a storage tank. In the experiment, the vehicle under testing was a 1988 c.c. 4 cylinder Nissan Sentra with spark timing 16 BTDC (before top deadcenter). The emission test were tested with HAMA LPS 3000 dynamometer and MTG-5. The ignition timing are 12°, 14°, 16°, 18°, and 20° BTDC. Europe Emission standard cycle was run for the emission test. Results show that the emission of HC decreases and both NOx and CO increase with using the spark plug reforming system without changing the spark timing. The best spark timing of the engine was 14° BTDC, especially for the vehicle operated in high speed. In this operating condition, the HC and NOx decreased and CO2 increased, however, CO also increased.
