A Texaco L-163S TCCS engine was operated with pure methanol to investigate the origin and mechanism of unburned fuel (UBF) and formaldehyde emissions. Both continuous and time-resolved exhaust gas sampling methods were used to measure UBF and formaldehyde concentrations. Fuel impingement is believed to be responsible for the UBF emissions from this methanol fueled TCCS engine. At increased load we believe that it is the primary source of the UBF emissions. Formaldehyde emissions were found to originate in the cylinder gases, especially at low load, however the formation of aldehydes in the exhaust port after leaving the cylinder does occur and becomes more important as the load increases. Increasing the engine load resulted in a decrease in both UBF and formaldehyde emissions. Increased engine speed resulted in slightly increased UBF and formaldehyde emissions.
