Abstract

In the present investigation, the behavior of fuel consumption was studied due to the high cost of gasoline and its price increase in Ecuador in recent years, for which reason the different mixtures have been studied to obtain lower consumption. The optimum fuel mixture rate for a T18SED e-tec II engine, Multiport Electronic Fuel Injection System (MPFI) between extra gasoline, super gasoline, and ethanol was obtained on two urban roads in the city of Quito (Ecuador). For the first test, mixtures of 10% super gasoline and 90% extra gasoline were made, and so on, for the following tests: (20–80), (30–70), (40–60), (50–50), (60–40), (70–30), (80–20), and (90–10) % super and extra gasoline. Then, mixtures between super gasoline and ethanol and extra gasoline and ethanol with concentrations of 5% and 10% were made. The results showed a low consumption on Maldonado Avenue with the 20% extra and 80% super mixtures obtaining a value of 2.9 L, while the mixture that presented a higher consumption was 100% extra of 3.4 L. At the end of each test, the fuel tank was completely drained, and the engine control unit (ECU) was reset for each test. The data acquisition was carried out through an OBD II (on-board diagnostic system) installed in each of the tests.
