Turbocharger with steel casting turbine housing
Patented turbine /center housing connection with tie-rod screws
RAAX turbine technology for best transient response
The turbine stage was developed with the main objective of optimising the inertia, in order to guarantee optimum transient behaviour. The turbine mass flow rate was sized to exactly meet the turbine inlet pressure requirement.
Ring shaped catalyst consisting of an outer mantle, a ring shaped matrix, and an inner mantle.
The swirl flow at the turbocharger outlet, which is also to be found in the ring catalyst’s inner pipe.
With conventional wastegated turbochargers or fixed geometry turbochargers (FGT), a turbine flow area cannot be adjusted during operation.
Knocking is abnormal combustion in which the air-fuel mixture ignites prematurely due to exposure to high temperature and pressure, creating an unwanted high-frequency noise. When the compression ratio is increased, the temperature at compression top dead center (TDC) also rises, increasing the probability of knocking.
