Burning Velocities in Methanol-Indolene Air Mixtures in a CFR Engine

A study of the burning velocities in Methanol-Indolene-Air Mixtures has been completed in a CFR engine. The investigation included measurements of ignition delay, combustion interval, and flame speed over a wide range of compression ratios (5.0 to Knock Limited Compression Ratio) and methanol concentration (0 to 100%). The results indicated that by adding methanol to indolene, ignition delay, combustion interval and MBT (Minimum Advanced for Best Torque) spark advance decreased. Adding methanol to indolene results in an increase in flame speed, burning velocity and the Knock Limited Compression Ratio.
