A study of the performance characteristics of Indolene-Methanol Plus High Alcohols (MPHA) has been completed. The study includes the measurement of fuel properties and performance parameters. The fuel properties investigated are distillation characteristics, heat of combustion, flash point, specific gravity and water tolerance. The performance parameters measured are MBT spark advance, power output and thermal efficiency. The alcohol concentration was varied from 0 to 100 percent by volume in clear indolene.
The measurement of fuel properties indicated that, in general, MPHA-indolene blends have higher water tolerance, similar specific gravity, similar flash point and different distillation characteristics compared to methanol-indolene blends.
The performance parameters were measured using a single cylinder CFR spark ignition engine at different compression ratios. The results of the performance measurements indicated that indolene-MPHA blends have a higher MET spark, advance, similar power output and lower thermal efficiencies than indolene-methanol blends.
