Evaluación del uso del aire acondicionado en vehículo Suzuki SZ en ciclos de conducción dinamométricos

Abstract

According to the data obtained in recent years, it can be seen that due to the increase in the number of vehicles, a higher percentage of polluting emissions into the environment is evident; the purpose of this research work is to evaluate the factors of gas emissions, torque and power when using air conditioning and the main gasolines marketed in Ecuador (extra and super), by means of simulated cycles in Chassis-Cycle dynamometer (Japanese 10-15 and NEDC Cycle), to identify the best variant in the parameters analyzed. For the study, the laboratory of the Technology Transfer Center for Training and Research in Vehicle Emission Control (Centro de Transferencia Tecnológica para la Capacitación e Investigación en Control de Emisiones Vehiculares-CCICEV), facilities belonging to the Escuela Politécnica Nacional (National Polytechnic School), was used. Two types of fuel were used; extra 87 octane and super 92 octane, taking into account the vehicle's air conditioning (with/without operation); two driving cycles were used, the Japanese 10-15 and the European (NEDC). As a result of the tests carried out on a chassis dynamometer for the established treatments, the best results were obtained for T7 (super fuel, without air conditioning and the European Cycle) and T5 (super fuel, without air conditioning and the Japanese 10-15 Cycle). The treatment with the lowest efficiency was T2 (extra fuel, with air conditioning and Japanese cycle 10-15).
