Abstract:
Currently the high demand for quality and low pollutant emissions in the Diesel commercial vehicles market, it is notable the increase in the sensitivity variation of components. In a commercial vehicle, we have the engine as the main agent, since it has many components under industrial manufacturing processes which may present variations, mainly when it requires critical adjustments. One of the most significant components in the engine performance is the turbocharger. Based on the difficulty to meet the design specification adjustment, this study was performed to detect the possible influences of the waste-gate actuator adjustment. In addition, the study also considers the contribution in terms of emissions, whereas the current legislation requires stringent levels. Therefore, the research was divided into vehicle tests (performance) in a controlled test track with different settings and emissions tests in a steady-state dynamometer.
