Análisis del consumo adicional de combustible que genera el uso del aire acondicionado a los usuarios en vehículos livianos en una ruta en la ciudad de Riobamba

Abstract

This degree study of investigative nature considers the fuel consumption analysis in real driving tests with the air conditioning system activated and deactivated. The tests were carried out under common driving conditions with vehicles dating from the last five years, in two different displacements, and with mechanical air conditioning systems. For these tests, 85 octane (extra) gasoline was used as fuel, the Torque pro application to provide live consumption data second by second, and an onboard fuel pressurization equipment of Liqui Moly brand. That delivers fuel to the fuel supply system at the same pressures as each system for its normal operation. The use of A/C in the test vehicles has positive effects on the comfort of the passenger compartment, but also negative effects such as fuel consumption, the same that is evidenced in the performance of the SA l 9R test vehicles, which decreases its yield by 8.76%, SAl9B 8.96%, RI017B 6.95% and the vehicle RIOI9B in 21.96%. In the instantaneous yield per canister tank, the SA l 9R vehicle varies by 9.28%, the SA I 98 by 7.03%, the RIO l 9B by 6.14%, and the RIO l 7B by 7.39%. With the obtained results, it can be evidenced that fuel consumption has a higher increase when the air conditioning system is being used. To obtain data, it is crucial to correctly program the application based on the live data to be obtained and carefully operate the remaining fuel measurement accessories, since a wrong procedure can modify the results. It is recommended to install the canister tank by a professional in the area, to avoid fuel leaks, opening the possibility of obtaining erroneous data.
