Sapre, A R

Methanol-gasoline blends containing 30 to 70 percent by volume methanol have potential to eliminate, or at least alleviate, major technical problems with the use of neat methanol such as safety, cold start and the reduced vehicle range. However, little information exits on their properties, performance and emissions. Experiments were carried out in a spark-ignited, single-cylinder, variable compression ratio, Waukesha RDH engine with primarily commercial grade unleaded gasoline, commercial grade methanol, M30, M50 and M70 methanol-gasoline blends to compare efficiency, performance and emissions characteristics. The fuels were compared at their knock-limited compression ratios and MBT spark-timing.
