Why do so many Americans hate European trucks?

You should've panned right a bit & included ALL of the "Governor Valve".......!!

 

I've looked into it and you'd need a huge amount of power to pull the CFM needed through the rad.

 

I looked it up, and it is a remarkable power wasting system. Opening the inlet valve, and sucking in air, and pushing it out via the same inlet valve is wasting lots of energy and thus HP. I can imagine that closing the inlet valve world be far more efficient. It would result in an almost 100% adiabatic process in the compressor, and that is far more efficient.

 

Perhaps you should patent a better one and make millions off of it.

 

Actually, such fans are available:

The motors are 1.25 HP or about 1kW, that's not so much.

 

Perhaps you should study up on it a bit more.

It is remarkably efficient as it will likely provide 120 psi to the system for a million miles, without causing downtime or unnecessary repair bills. I could reduce the parasitic loss even more by sourcing air to the compressor between the filters and the turbo rather than using air from the intake manifold.

The cost of fuel to run this compressor, on this truck, is de minimus. Please tell me what compressor you would recommend for a replacement.

 

If you read the rest of it the motor must be under 450hp and benefit from ram cooling.
Ive run trucks on the dyno and it takes a bit more then 1.25hp to run the fan

 

About 80 amp draw on 12 volt and around 40 amp draw on 24 volt. What you gain from the fan you'll likely lose at the alternator.

 

I've been wondering the same thing..

All these electric Motors to drive the ancillaries will require a Big Alternator/generator.

Will the power required to produce the electricity be any less than the power required for the engine to direct drive the ancillaries??

The Alternator/generator & electric Motors will also produce heat which will need to cooled/dissipated, also requiring energy...

I'm aware that the driver for all this (for want of a better word) Hoohaa is reducing emissions. But some of it seems to be a bit (shall we say) self defeating..

 

They will use the heat from the motors and brakes in some kind of star trek warp drive........
