摘要

The study was conducted to assess the suitability of denatured ethanol of different proofs as a fuel in place of kerosene in petrol start kerosene run type small spark ignition engines used in India. In this study, performance test of three different compression ratio Honda make petrol start kerosene run engines viz. GK200 model (CR 4.5: 1), GK300 model (CR 4.8: 1) and G300 model (CR 6.5: 1) was done on denatured ethanol of 200°, 190°, 180° and 170° proof and kerosene (base fuel). The observed results of experiment indicated that the different denatured ethanol proofs were found to have similar power producing capabilities as kerosene. Fuel consumption, brake thermal efficiency and bsfc were found higher on denatured ethanol poof than kerosene. Results also indicate that higher the compression ratio better is the brake thermal efficiency and lesser brake specific fuel consumption. In addition, emission of UBHC was less, whereas NOx was more in denatured ethanol different proof than kerosene. The 1,800 proof denatured ethanol is recommended for use in engines.
