Depletion of fossil fuels, volatile petrol prices and vehicular pollution have increased interest in renewable fuels for spark-ignition (SI) engines. Ethanol, a renewable oxygenated fuel with a high octane rating, can be blended with petrol, but its lower calorific value and material compatibility issues complicate its use. This paper experimentally evaluates ethanol–petrol blends from E0 (pure petrol) to E100 in a four-stroke, single-cylinder, air-cooled two-wheeler engine (Hero Honda Passion Plus). Blends were prepared in 50 mL volumes in 10% increments. Mileage, fuel consumption, starting behaviour, throttle response and smoothness were recorded, and CO, HC, CO2 and O2 were measured with an exhaust gas analyser. Mileage fell steadily with ethanol content, from 30.5 km/L (E0) to 29.8 km/L (E10), 29.0 km/L (E20) and 21.1 km/L (E100), a 30.8% reduction at E100. CO fell from 0.16% to 0.03% (about 81%). HC fell from 196.5 ppm to a minimum of 112 ppm at E80 before rising at E90 and E100. CO2 and O2 rose modestly. Starting and running quality degraded above E30 and became poor above E70. E10–E20 gave the best balance, with under 5% mileage loss, a 25–40% CO reduction and no drivability penalty. Because the tests were short, single-run and carried out on an unmodified engine, the findings are indicative and should be confirmed by repeated, dynamometer-based and durability testing.
KEYWORDS
Increasing ethanol content in petrol lowered CO by up to about 81% and reduced HC in all blends (minimum at E80), but reduced mileage from 30.5 km/L to 21.1 km/L at E100 and progressively impaired starting and smoothness in an unmodified two-wheeler engine. Low blends of E10–E20 offered the best compromise, with under 5% mileage loss, meaningful CO and HC reduction and normal operation. High blends require engine recalibration and ethanol-compatible materials. Future work should include repeated mileage trials with accurate fuel-consumption measurement, dynamometer-based power and torque tests, NOx measurement, engine optimisation (air–fuel ratio, ignition timing, fuel injection), long-term durability and material compatibility studies, and real-world road trials.
