Abstract
Since 1991, a University owned truck has been operating with natural gas. In order to improve emissions performance a different fuel management strategy was developed. With the help of Siemens Automotive in Newport News, VA, a liquid fuel injector was modified to handle natural gas. The basic engine was tested to determine the benefits in emissions that the multi-point injection system can have over the single point injection system that had been used previously. Pre-catalyst, raw exhaust-gas data for the more important pollutants were taken and analyzed in both systems under different loads and intake manifold pressures. In addition, to obtain a minimum-emissions calibration of the engine, the effects of spark advance on pollutant concentration were studied. The results were compared and displayed in graphical form.
The different tests performed showed that specific pollutant emissions were less for the multi-point injection system. Other engine parameters showed the multi-point injection system as a better fuel management option.
