A coal-derived synthetic fuel was blended with a control diesel fuel and then tested in a single-cylinder, direct-injected, diesel engine. Comparisons of the blended fuel to the control Diesel fuel were made on the basis of performance, combustion characteristics, gas-phase emissions, including aldehydes, and particulate emissions. In addition, the mutagenic activity of the soluble organic compounds from the particulates were analyzed using the Ames test. The objective of these experiments was to determine how well the fuel blend would perform as a direct replacement for diesel fuel. Use of the blended fuel decreased performance and increased gas phase emissions, but particulate emissions were unchanged. However, a significant increase in the mutagenic effect of the soluble organic compounds was observed with the blended fuel.
