The matching process
Each of our turbochargers is developed for one specific engine type or model. This is a long and complex process where all engine parameters are evaluated several times to ensure a perfect match. There is no one-fits-all turbocharger. Substituting one turbocharger for another can result in poor transient response, loss of peak power, low end torque and undesirable fuel consumption.
Turbocharger matching is the process of selecting the optimal compressor and turbine combination to reach the engine performance requirements. Since these requirements are different for every engine type or model, a matching will always result in a solution specific to the application. Turbocharger matching is an iterative loop, where after each step the engine performance parameters are evaluated. Parameters such as torque, power, BSFC, inlet and exhaust temperatures and pressures. A suitable compressor will be selected based on the maximum torque and power target at a given engine rpm. Additionally, a turbine will be selected which is matched to drive the chosen compressor.
