Developing and designing fuel-efficient vehicles to run a marathon One gallon of fuel is a challenging task. The machine must be optimized to achieve maximum fuel efficiency. In this study, the optimal evaluation of the compression ratio (CR) and ignition time that produces the best torque in the custom gasoline engine that uses E100 Ethanol fuel. In the first experiment, CR adjusted between 9 and 12 to evaluate its effect on the note of the mileage of the engine. Experiments are carried out on the testing path. In the second experiment, ignition time is adjusted to the engine control unit (ECU) which is made specifically between 15 & deg; and 45 & deg; Before the top dead point (BTDC). The engine performance is investigated in terms of the best torque and consumption of specific fuel brakes (BSFC), with variations in engine speed between 1500 and 8000. Testing is done by dynamometer. Testing is also carried out in the constant compression ratio and stoichiometric fuel ratio, 9. The best results are used to develop small, sustainable, and efficient urban cars for the Asia Eco-Marathon Shell competition. We achieve the best CR 12 with an average distance of 212.3 km / liter. The lowest BSFC was obtained at 4500 rpm which produced 9.68 n.m.
