Performance Evaluation of Twin-Scroll Wastegated Turbo charger to Match with 3.0 Litre Diesel Engine

Abstract

Abstract. This study investigated the compatibility and performance of a twin-scroll wastegated turbocharger to match a 3.0-liter diesel engine, which can produce the power output of 300 hp - 550 hp. The twin-scroll wastegated turbocharger is selected from the BorgWarner turbocharger of the EFR model series. This study utilized the web-based turbocharger matching tool, which is operated by inputting engine-specific parameters and simulating performance targets. Throughout the process, context-sensitive guidance is provided, including recommended ranges for complex parameters such as Brake Specific Fuel Consumption (BSFC), Volumetric Efficiency (VE), and exhaust gas temperature. Upon completion of data entry, the tool outputs detailed compressor and turbine performance metrics, including characteristic maps. Based on the simulated input and performance outputs, the EFR 7064-C turbocharger was selected as the optimal match, aligning well with the engine’s power requirements and operational characteristics.
