Air Restrictor and Turbocharger Influence for the Formula Student Engine Performance

Scalable turbocharger performance maps for dynamic state-based engine models

Adapting turbocharger performance maps to a form suitable for dynamic simulations is challenging for the following reasons: (1) the amount of available data is typically limited, (2) data are typically not provided for the entire operating range of the compressor and turbine and (3) the performance data are non-linear. To overcome these challenges, curve fits are typically generated using the p...

Numerical Investigation of the Effect of Cooled EGR on Turbocharger HCCI Engine Performance Fueled with Methane

Turbocharger Design and Performance Analysis

Performance testing identifies many aspects of turbocharger performance. Although, when performance is less than satisfactory, test cell mapping only identifies secondary or tertiary troubles demonstrating inconsistencies with expected performance. Such tasks as seeking out and eliminating efficiency losses or increasing operational surge margin are unrealistic expectations when basing your con...

experimental and numerical study of an on-engine turbocharger performance under the inlet pulsating flow

the present work is focused on the performance analysis of a 1.7 liter engine with turbocharger. the ultimate target is studying the response of the turbocharger to the inlet pulsating flow. such numerical analysis requires the time variation of pressure and velocity at turbine inlet. in order to achieve such information, one dimensional unsteady viscous compressible flow within a 1.7 liter tur...

Improved Performance Prediction Model for Turbocharger Compressor

In order to improve centrifugal compressor performance predictive capability, an improved recirculation loss model in two-zone modeling system is presented in this paper. The new loss model correlates Reynolds number of the impeller with the recirculation loss. Performance prediction by the improved model is carried out on two turbochargers with different sizes based on COMPAL mode of the code ...
