In these experiments a regular automobile engine with 4 cylinders, 4 strokes and 1,3 liter volume was used. Without making any modifications on the engine, the engine performance has been determined for both fuels between the ranges of 1100-4000 rpm, 5-40 Nm torque values. In the experimental study, the rotation number, torque, strength, mean effective pressure, brake specific fuel consumption, fuel flow rate, exhaust temperature and exhaust emission values of the engine have been measured. According to the experiment results, if the engine works on gasoline, its minimum brake specific fuel consumption becomes 400 g/kWh, whereas if it works on methanol this value becomes 900 g/kW. The values of CO emission of the engine vary between 2 and 6% for gasoline, whereas the range for methanol is between 1 and 4%. Minimum HC emission values, on the other hand, have been observed as 330 ppm for gasoline and 250 ppm for methanol.eninfo:eu-repo/semantics/closedAccessSpark ignition engineEngine performanceMethanol fuelExhaust emissionsArticle310130128WOS:000291125500031N/A
