Flexible turbocharging



The VTA system can be optionally fitted to both TCA and TCR turbochargers. It enables the charge air volume to be precisely matched to the quantity of injected fuel across all points of an engine's load and speed range. The result is increased engine efficiency, reduced SFOC, lower emissions and improved engine response.

Minimizing consumption and emissions

VTA (variable turbine area) allows charge air delivery to be optimized to demand for charge air precisely, steplessly and continuously at all engine loads and speeds. VTA minimizes fuel consumption and related exhaust emissions. 


    • Reduced consumption: up to 5 g/kWh lower fuel consumption
    • Reduced emissions: lower soot and smoke emission and lower particle emissions
    • Easy application: suitable for TCA and TCR turbochargers and retrofit packages
