| Abstract: |
| Energy supply is one of the most important issues in the world today. The most consumption of fossil fuels is in internal combustion engines. The increase in the global price of fossil fuels and the increase in environmental warnings in the world have caused researchers to look for renewable sources for these types of fuels. One of these methods is the use of biofuels, which include mixtures of the main fuel with ethanol, methanol, and butanol. This study was conducted with the aim of evaluating the energy balance of a four-cylinder gasoline engine with ethanol and butanol biofuels at three different revolutions of 1000, 1500, and 2000 rpm. The test results showed that the braking power of the tested engine increases in fuel compounds that contain bio-alcohols compared to pure gasoline fuel. It can also be concluded that the braking power of the fuel compounds has increased with the increase in the speed of the test engine. Also, the heat loss of the exhaust in biofuel compounds has increased compared to pure gasoline, and the heat loss of the engine also increases with the increase of the engine speed. Pure gasoline fuel has lower cooling system losses than other tested fuel combinations, and cooling system losses increase with increasing speed from 1000 to 2000 rpm. In the uncalculated thermal losses, we see a decrease in losses with the increase in speed, and these losses in the combination of biofuels also decrease compared to pure gasoline. |
