Cold Starting Tests on a Methanol Fuelled Spark Ignition Engine 831175

The present cold starting performance of methanol fuelled spark ignition engines is poor compared to their gasoline counterparts. Apparatus has been developed to cold soak a small engine to temperatures as low as −65°C. Tests have been conducted using methanol, Indolene and sample of commercial gasoline of depressed volatility. Data are provided showing the effect of fuel-air ratio on minimum starting temperature for the three fuels. Methanol failed to start at temperatures below about 0°C whereas the Indolene started easily to below −45°C. Reid Vapour Pressure is shown to be ineffective as a predictor of cold starting performance for methanol.
