Desarrollo de un limpiador de inyectores de gasolina con un banco de pruebas automático para el servicio automotriz Los Nogales.

Abstract

For the present work is to explain everything that is needed to make a team of evaluation and cleaning of the injectors of engines, this equipment consists of a test bench developed by a Raspberry PI 3 card that controls and simulates the work that has An injector is an internal combustion engine by testing one of the injectors. A cleaning equipment can also be used for the corrective maintenance of the injectors that is implemented through a medium inverter circuit that produces the power and frequency required for the cleaning process of injectors. Nowadays, the cleaning process most used at an industrial level and more efficient is ultrasonic washing, which uses as a principle of operation circuits oscillating inverter circuits. For the execution of the project, it was divided into two fundamental parts, the first being the design and construction of the test bench and the second, the ultrasound cleaning system. For the construction of the test bench, a PWM control was controlled with the Raspberry PI 3 card, which simulates the working conditions of an injector, and by means of an artificial vision system was processed at the level of the present liquid levels in each test of operation to which the injectors are subjected, in addition this bank of tests consists of a SCADA system in which the operator can control and monitor the different tests applied to the injectors. For the construction of the ultrasonic washing, a half bridge inverter circuit was used, which by means of a piezoelectric transducer generated a power of 50w and a frequency of 40 KHz necessary for the operation of the cleaning system.
