I know there are some exhaust generator, but battery control is a hard work, so I decided to make some pure physical ERS-H system

all we know it, turbo charger generate air pressure, how about we put a extra turbo charge, but the compress air supply to a air tools connected to power train?

If you are going to do that, cut out the compressor section and couple an exhaust turbine to the crankshaft. The old Wright 3350's did it for aircraft engines. But I doubt that it would be low cost or even cheaper than an off-the-junkyard-shelf turbo-charged engine..

turbine to the crankshaft is turbo compound, used in heavy duty vehicle

Weren't those notoriously unreliable? I thought they typically eliminated the power recovery turbine for this reason for civilian use?

Then again we have had 70 years to improve the design. :cheers:

Andrew,

The turbo-compound Wrights did eat valves in their early years but they were an effective engine on the Canadair Argus ASW aircraft where the low-altitude operational envelope made turbo-compound more useful than turbo-charging. (The Argus was a P-3 predecessor loosely based upon the Bristol Britannia airframe, as the P-3 was upon the Lockheed Electra, but the Argus reverted to piston engines from the Britannia's turbo-props.)

I worked with a guy that was a tech with Cummins engines in 80's. He said they tried boosting driveshaft power by u gearing a turbo to the driveline. The vibrations and micro speed changes ate gearing to the turbo like crazy. He wanted to try driving an alternator with the turbo, then the electricty could be used for anything and everything.

Brass said "No". Seems like a sound idea to me.

Maybe I'm not talking clear, but I'm not talking about Turbo to shaft.

exhaust blown alternator will be simple, but the control unit is hard to make, specially battery system.

here is a draft of my concept

So basically you want to put a windmill up in the intake tract air flow and use it to drive an alternator?
Wouldn't it have fewer losses if you put it in the exhaust stream after the unit supplying combustion air the engine?
You could also take a look at the systems going on class 8 trucks using piezoelectric panels inside the exhaust pipe for electricity generation.

Turbos are high volume and low pressure devices. Air motors are high pressure and low volume devices. I don't think this will work the way you are hoping.

the turbo is only for motor, no engine air intake
