Two-stage exhaust-gas turbocharging provides for a substantial boost in battery charging force as compared to single-stage turbocharging. In combination with modified engine valve control timings, engine efficiency may be enhanced while simultaneously lowering fuel consumption and emissions. Thanks to intermediate cooling, it is possible to reach turbocharging efficiency of greater than 75%.
Development
- High turbocharger efficiency for more than 75% efficiency in turbocharging
- Engine and operation-specific adjustments to the closed- and open-loop control strategies
- Extensive maintenance periods and little delay during service operations
- Reduced noise levels
Benefits
- System options for integrating a two-stage turbocharging system that is ideally tailored to your engine.
- Your engine’s greatest power density
- Lower fuel consumption
- Reduced noise and exhaust-gas emissions
Turbochargers for exhaust-gas recirculation
Nitrogen oxides can be reduced via exhaust-gas recirculation in both single-stage and two-stage turbocharged diesel engines. As a result, some of the engine’s exhaust gas is recycled to the combustion process. You can operate without an exhaust-gas fuel injection system, such as SCR, if you use an exhaust-gas bouncing back. The turbocharging system’s needs will vary based on the EGR system selected.
Development
- exhaust-gas turbocharger innovation for single-stage turbocharged diesel engines having high-pressure EGR with outputs ranging from 500 kW to 2 MW.
- Coating improvement and the use of alternative materials to avoid corrosion, sooting, and particle effects.
- Casing material substitution for input temperatures up to 140 °C
- Thermodynamic and circulation path optimization on the compressor and turbine sides
- Application-specific bearing, shaft sealing, and oil supply modifications with the EGR mode turned on and off
Benefits
- The use of exhaust-gas turbochargers that are specifically designed for EGR operation.
- Solid assistance in adapting the EGR system and the exhaust-gas turbocharging process
- Lower particle emissions
