Repotenciación de un motor diesel e implementación a un banco didáctico para el laboratorio de motores de la Escuela de Ingeniería Automotriz de la ESPOCH.

Abstract

The engine power upgrade of a Nissan diesel and implementing a didactic laboratory bench for automotiveengineering school intents increase engine power, reduce emission of pollution gases and it is used as a learning tool to develop applications in knowledge and skills.The technical diagnosis of the engine determined damage status and lack of important parts that had to be replaced for the bank didactic performance.Once completed all the missing parts, a study of selection, design and simulation was carried out of the critical parts that incorporate each one of its modified systems. The cooling system constituted by a coolant pump, radiator, thermostat, coolant tank and hoses, turbocharger systemcomposed by a turbocharger, intercooler pipes and high pressure; lubrication system made up an oil filter, oil tank and additional pipes to lubricate additionalsystems; the feeding system low pressure fuel is comprised of an electric pump, a fuel filter/ water pump, manual drain pipes and instrument control system with pressure gauges, indicators and electrical circuits.The frame construction, location and assembly of parts and systems mentioned above, constitute the method of adaptation.Within the comparisons made on the results of standard engine with the modified, and increase in engine power of 53 to 62 hp and additional volumetric efficiency 17.47% in the mass of air per cycle was obtained; as well as, the results obtained in the thermodynamic studies, manuals and maintenance practices where entered in the table to compare the behavior and performance analysis of the engine. It is recommended to extend the studies made to the engine Nissan resulting in improved technology in several areas.
