The cold starting performance, emissions, and engine wear of several vehicles fuelled with neat methanol are being evaluated in a continuing programme undertaken by Transport Canada. Two vehicles fuelled with gasoline are included as controls. Data on the cold starting performance of three different types of vehicles with fuel injection are presented. Tests were conducted at progressively lower temperatures until the vehicle failed to start. During the tests, intake air, engine coolant, oil and exhaust temperatures, engine speed, and battery voltage were monitored. Cranking time is presented as a function of ambient temperature. Exhaust emission data, including those for aldehydes, are presented for ambient temperatures of 25, 12, 0, -10, and -20 Cel. Emission measurements are continuing as kilometrage is accumulated on a test track. The emission data are reported as a function of ambient temperature. Engine wear is monitored during the programme by analysing oil samples. Data from the oil analyses to date are presented which show the engine wear rates.
