Air Guide

The central component of the air supply system is the air-charging module installed in the inner V of the engine, which contains the supercharger bypass control and charge-air cooling system.







The following criteria are crucial for a decision in favor of a mechanically powered compressor:
- High comfort requirements
- Powerful drive-off characteristics, wide range of uses, from comfort-oriented to very sporty
- The engine can be used in several vehicle models due to its characteristics
- Fulfills all current emission standards as well as standards EU5 and ULEV II, which will come into effect in the near future










Advantages and disadvantages of mechanical turbocharging with a Supercharger compared to turbocharging with an exhaust turbocharger

Advantages:
- Boost pressure available immediately when required
- Boost pressure delivered continuously and increased in line with the engine speed
- The charge air does not require such intensive cooling
- Extended service life, low-maintenance operation
- Compact design (space-saving installation in the inner V in place of the intake manifold)
- Low fuel consumption
- Fast, dynamic torque build-up, early peak torque for good drive-off characteristics
- Air travels short distances into the cylinder prior to compression, which results in an extremely low air volume and spontaneous drive-off characteristics
- Improved engine emissions. Reason: The catalytic converter reaches operating temperature more quickly. On a turbocharged engine, some of the heat energy for powering the turbocharger is lost

Disadvantages:
- Very complex manufacturing process due to very tight manufacturing tolerances (rotors in relation to the housing and one another)
- Extremely sensitive to the intake of foreign debris in the clean air section
- Relatively heavy
- Complex measures required for sound insulation
- Some engine power is lost when the blower is powered
