Modeling and control of wastegate equipped turbocharged engines
… equipped with pneumatic, spring diaphragm, wastegate actuators, with solenoid valve active boost control. The method revolves around the joint simulation of the engine with Ricardo WAVE software and the control algorithm with Simulink®. A component by component modeling approach is outlined …

Turbocharger Turbines: An Experimental Study on the Effects of Wastegate Size and Flow Passage Design
… automotive turbochargers of varying turbine/wastegate combination: two of similar turbine housing (BorgWarner) but different bypass throat diameter (20 and 26 mm), and a third of both different housing (Honeywell) and throat size from the former two (21 mm). The effects of turbine housing …

Aufladung von Pkw DI - Ottomotoren mit Abgasturboladern mit variabler Turbinengeometrie
… wurde bislang der Schritt vom einfacheren Wastegate-Lader zur VTG noch nicht unternommen. Die Gründe dafür sind insbesondere in der höheren thermischen Belastung, aufgrund der höheren Abgastemperatur, und der größeren Luftdurchsatzspanne zu finden. Andererseits besteht inzwischen speziell …

Aerothermodynamics and operation of turbine system under unsteady pulsating flow
… wheel performance, the diffuser loss and the wastegate port loss appear locally quasi-steady such that we can characterize the performance of the components based on a series of steady calculations subjected to varying inlet conditions reflecting the inlet flow pulsation; (2) the operation of …
