Condition Monitoring of A Diesel Engine Turbocharger for Effective Performance Analysis

Abstract

The diesel engine consists of several components which enhance its efficient and effective performance. One of these components is the turbocharger unit-compressor and turbine. It was found from this work that the overall efficiency of this unit depends mainly on the performance of the compressor and turbine components of the turbocharger unit. The test engine was an MTU 12V 396 TC 32 diesel engine. In this work, component modeling was adopted as the best means and synosure for achieving this aim of effective engine performance applying CM to avert failure and engine awn-tire, thus increasing the useful life of the equipment. It was carried out to determine the turbocharger boost pressure. A software code named "TOP B" written in Quick Basic programming language was developed for the analysis. The data obtained shows boost pressure and exhaust temperature increased at the range of 0.1 bar and 10°C respectively. The results revealed that the turbocharger is able to develop enough boost to scavenge the cylinder of the exhaust gas as further. It also shows that the model developed is capable of predicting any blockage the air intake filter may experience. In view of these, it is highly recommemded that Condition-based maintenance philosophy should be used to increase its reliability and flexibility.
