OM 605.960 2,5 L 5 Zylinder Turbo 20 Ventiler marinesieren | Posts 80+

The ESP has been completely rebuilt, and I'll be holding it in my hands in a few days.

Here's my other project.
The renovation of the swim platform is complete. I am thrilled.

I'm finally getting back to the OM605.960 engine rebuild project after a long time.
I purchased a mechanical injection pump for an OM 605.911 some time ago. The OM 605.911 is the naturally aspirated diesel version of the 605.960. With Matthias' help, the pump was adjusted to match the settings of the electronic ESP system from the 605.960.
Thank you to Matthias and Mr. W........
I will provide an update once I have installed them.
Here are the first pictures.

Well, it looks like everything worked out after all.
Did you have to install larger pistons, or did they still have enough potential?

Everything could stay as it is, and there should still be some reserve left.

The MESP is mounted on the engine.

Here are the pictures.

The material for the turbo adapter to the manifold flange and from the 3-inch V-band to the exhaust is here.
Here are the pictures.

Hi, are you sure the ATL isn't a little too large?
An OM 352 engine has a displacement of approximately 5.7 liters! The maximum power output is achieved at around 2800 RPM.
You would really have to heat up a 2.5-liter engine to get enough boost! Or what RPMs and fuel injection rates are you planning to use?

Best regards,

The loader is a K 26 model. The standard configuration for the 2.5-liter VW engine includes a K 24 loader. A K 26 loader is used for tuning purposes. The data sheet specifies a maximum output of 300 horsepower. I will first check what boost pressure I can achieve at different RPMs.
The mechanical ESP has been precisely calibrated to match the values of the electronic ESP.
However, the amount of fuel injected can still be increased.

Hi,

That must be a boat engine. The turbo lag will likely be rarely noticeable there.
For that, Wolfgang will be able to increase the fuel injection amount.
and it will not produce high temperatures or exhaust backpressure.
I think the charger is perfectly fine.

Best regards, Rodion.

Thank you .

Nothing for that .
I'd like to experiment a bit with the fuel injection amount.
You have a large displacement engine, a four-valve design, and a big turbocharger.
It's easy to get 200 horsepower out of it.
Best regards, Rodion.

Until that time comes, I'm sure 2 or 3 more manatees will move to the country.
But then .

Hello,
A very simple question about the KKK K26 turbocharger.

Isn't that the standard turbocharger from Volvo Penta?

I would need to do some more research on that. If you search for the number using Google, it returns "OM 352". Also, according to KKK, this turbocharger was only used with the OM 352 engine in the Witzemann design.

Hello,

I did some research on that.
Your turbocharger was manufactured on March 1, 1985, for Wizemann, a marine engine with an output of 89 kW / 121 hp.
Do you really want to install this turbocharger?

The newer turbochargers (KKK K26, for Volvo Penta) were optimized by modifying the geometry of the impeller. This resulted in slightly more torque at lower engine speeds. Subsequently, a supercharger was added (e.g., the Volvo Penta KAD32).

We're only answering now that we've been in Croatia for 3 weeks.
Where it matters, the turbocharger is water-cooled in the exhaust gas area.
I will test it with him.
Can you tell me something about the other charger I still have?
I tried to find a datasheet.
I wasn't successful in doing that.

Hi there,
I think the turbocharger is massively oversized.
I predict that very little happens below 2500 rpm.

Which VW engine are you referring to? I only know about the Audi 2.0L turbo-diesel 5-cylinder (engine code DE or NC), which used the KKK K24 turbocharger. And with those engines, the turbo was also hopelessly oversized. The response is absolutely terrible.
Audi initially used a K16 (still too large) with the 5-cylinder TDI engine (2.5l, engine code 1T, AAT), and later (engine codes AAT, AEL), they used a K14 .

"Volkswagen currently manufactures marine engines, and they also use water-cooled turbochargers in those engines, although much smaller ones, or even variable geometry turbochargers."

Jens.
