Is it important to install the turbocharger in a specific location?

Hi,

ist es beim Einbau eines Laders wichtig, dass der Ölzulauf oben und der Ölablauf unten ist?

Oder kann man den drehen, wie man will (Natürlich erfolgen Zu- und Ablauf über die richtigen Bohrungen)?

Okay, here's the translation, keeping the HTML/BBCode tags and URLs intact:

Also aus dem Bauch Raus: Ablauf nach unten, nicht das es nach dem ABstellen des Motors zu Verkokungen kommt.....

Refer to the manufacturer's specifications (data sheet) for the exact installation location.

This will probably end up being the same regarding the location of the oil drain within the housing. Crankcases only have contactless seals between the oil and air/exhaust, so standing oil would flow through.

Correct! The contactless labyrinth poem only works correctly when the rotor is turning.

If the oil were inside, it would seek a path around the seals.

Okay, hier ist die Übersetzung:

Aha, thanks for the information!

Can I tilt the rotor (e.g., compressor side higher than the pump side),
or must it be mounted completely horizontally?

Best regards, Rod

AGAIN:

This depends on the specifications of the loader. You should obtain these from the manufacturer, where the correct mounting position and possible tilting angles in all axes are specified.

This can vary significantly from loader to loader.

In general, nothing can be said about this.

Obtaining a data sheet is practically impossible.

The loader is a Perkins loader from a Perkins industrial engine.
This is not a KKK or Garrett aftermarket loader.

If nothing is known, I would also consider oil passage as a limiting factor when looking at the tilting angle. In this case, oil in the fresh air part would be more acceptable than on the exhaust side.

The weight of the rotor, which also exerts axial force, should be negligible compared to the gas forces, which also exert axial force. In larger flow machines, these forces are compensated for through a clever design that utilizes the forces on the "back" of the rotor. I believe that this would not work so well in a small ATL, especially since it is operated with very different load conditions.

This doesn't really help much. Without the datasheet, you won't be able to proceed.
Someone must have manufactured the charger. Perkins doesn't make their own.
There are still plenty of other manufacturers besides Borg Warner (KKK) and Honeywell (Garrett). Try IHI, MHI, Komatsu, Napier or Caterpillar. I would start with Caterpillar. They have built a lot of chargers for Perkins.

There are only very few chargers that can be tilted. The charger axle must be largely horizontal in most cases. Otherwise, the charger shaft bearings won't function properly and the closing would be extremely high.

Hello,

and thank you both.

So, I will aim to adjust the horizontal position of the loader arm.
Of course, this is not entirely easy, but I want the loader to hold and function properly...

Regarding the manufacturer:
It seems to be a Perkins loader, as there is not only a Perkins type plate, but also 'Perkins' is cast into the compressor housing.

I will take a photo if I have the opportunity.

Rod

Do you know the reason for this?

Think about how bearings are designed and how they work in a turbocharger. Especially when the oil pressure in the engine stops, the rotor would immediately follow with its full weight due to gravity (while still rotating at a relatively high speed). The bearing surface that faces "down" would quickly show signs of wear. In this case, you would need to counteract this constructively (which is certainly possible). However, this is not cost-effective at the rotor's speeds.

I can ask a counter-question:
Why are there so few known Otto engines with (bearing-supported) crankshafts that run vertically? They all run horizontally.

Same principle, but bigger

...to be honest, I can't think of any meaningful applications in the automotive sector specifically... perhaps in a helicopter or some other exotic machine...

ATL uses wedge-shaped bearings and not just simple contact surfaces because the gas pressure can be higher than the weight force in some cases. The radial bearings also have the same problem when the engine is stopped.

Lawnmowers also have a vertical engine.

...ok, exotic construction machinery and lawnmowers... but lawnmowers and bearings???
