Summary:

The objective of this research was to develop a global correlation for hydrocarbon (HC) emissions from a homogeneous charge spark ignition engine. Engine experiments were performed with a single-cylinder engine over a wide range of speed, load, spark timing and air/fuel ratios using both n-butane and iso-octane for fuels. A global HC consumption rate correlation was developed that was able to predict measured HC emissions from both fuels to within 15 percent over all operating conditions. The results imply that the majority of the HC consumption takes place in the bulk gas at temperatures higher than 1500 K, and that for part load, low speed operating conditions, the majority of the HC consumption takes place within the cylinder before the exhaust valve opens
