ANALYSIS OF DIFFERENCES IN TURBOCHARGERINLET GEOMETRY ON 2KD-FTV DIESEL ENGINE PERFORMANCE

Abstract

This study aims to determine and understand the effect of inlet geometry on the turbocharger on the performance of the 2KD-FTV type diesel engine and to determine the amount of power and torque produced from several variables after the testing phase. The geometry of the inlet channel used is speed with the aim of increasing the speed of air flow in the inlet channel. This study uses an experimental method used to determine the effect of one variable (flat pipe) with another variable (stuck speed). The object of the study used a 2KD-FTV type diesel vehicle. The DynoJet Dynamometer measuring instrument as a tool for taking measurement results. Data collection begins with the preparation stage, testing stage, comparison stage and analysis stage and is supported by documentation. Data is presented in the form of graphs and table results. The results of this study produce (1) changes in torque and power in the engine with the replacement of data pipes with stuck speed at engine speeds of 4,500 rpm of 3hp and at engine speeds of 5,000 rpm of 6hp. (2) Increase in torque at engine speeds of 5,000 rpm with data increases of 3 Nm.
