Abstract

The lack of fossil fuels, the increase in energy prices and environmental problems have caused many countries to switch to biofuels and renewables. The lack of fossil fuels, the increase in energy prices and environmental problems have caused many countries to switch to biofuels and renewables. with the aim of evaluating the energy balance of a four-cylinder water-cooled gasoline engine using gasoline fuel compounds and ethanol, butanol, propanol, and pentanol alcohols in different volume percentages at three different speeds of 1000, 1500, and 2000 rpm. The results showed that the braking power of the experimental engine showed different behavior in different volume percentages of the fuel compounds, and according to the amount of propanol, butanol and pentanol, the amount of braking power is different. The highest braking power related to fuel number 6 at the speed of 2000 rpm was 47.11 kW and the lowest value related to fuel number 1 was 21.81 kW at the speed of 1000 rpm. The highest amount of heat loss of the cooling system related to fuel number 6 was 10.84 kW at a speed of 1000 rpm and the lowest value related to fuel number 1 was 17.07 kW at a speed of 1000 rpm. The highest exhaust heat loss related to fuel number 6 was 17.07 kW at the speed of 2000 rpm and the lowest value related to fuel number 2 was 14.54 at the speed of 1000 rpm. The highest uncalculated heat loss related to fuel number 6 was 18.57 kW at 2000 rpm speed and the lowest value was related to fuel number 5 at 11.47 kW at 1000 rpm speed.
