Most recently, the TPR platform been successfully combined with ABB’s VTG. VTG allows precise control of boost pressure from the TPR 56 and TPR 61, improving the diesel combustion process in order to better address the typical demands on turbocharging systems for rail applications.
With the ability to greatly enhance the adaptation of charge air delivery to engine operating conditions, including enhanced response to load impositions, TPR turbochargers with VTG enable locomotives to cope better with the constant operating variations typical of rail traction applications, such as load modulation and, in particular, ambient conditions.
Using the VTG option, engine performance can be more closely adapted to operating conditions, leading to a useful saving of up to 4% on fuel costs in a typical heavy-haul rail application.
