Summary:

A Texaco L-163S TCCS (Texaco Controlled Combustion System) engine was operated with pure methanol to investigate the origin and mechanism of unburned fuel (UBF) and formaldehyde emissions. The effects of engine load, speed and coolant temperature on the exhaust emissions were studied using both continuous and time-resolved sampling methods.Within the range studied, increasing the engine load resulted in a decrease of the exhaust UBF emissions and an increase in the formaldehyde emissions. Engine speed had little effect on both UBF and formaldehyde emissions. Decreasing the engine coolant temperature from 85°C to 45°C caused the exhaust UBF emissions to approximately double and the formaldehyde emission to increase approximately 20 percent. It is hypothesized that both fuel impingement and spray tailing are responsible for the high UBF emissions.In-cylinder formation of formaldehyde was found to be the major source of the exhaust aldehyde emissions in this experiment
