WABCO Turbocharged compressors

WABCO Turbocharged compressors

WABCO Turbocharged compressors

(OP)
Hi.

I have always seen compressors intake after the air filter and before turbocharger.
But in these new Cummins BGE5-200 engines, compressor intake is after the aftercooler. (and, obviously after the turbo).

So this new compressors are "turbocharged".

What's the technical reasons?

The only reasons I have in mind, is that the compressor would be smaller. And the air flow would be greater.

How does it affect the air which is being sucked by the cylinders?

Thanks.

Hi Pat,

I think Azraelo means the on-board air compressor for air brakes, etc.

Azraelo, your conjecture about the purpose of feeding the compressor from the turbo makes sense to me.
The amount of airflow is relatively insignificant compared to the engine's total airflow.
