Deutz BF8M1015C Engine: Specs & Performance

Hello guys,

I'm having a problem with a Deutz BF8M1015C engine.
The cart simply lacks power.

I've already searched the entire internet, but I can't find any information about the boost pressure or anything else.

The suspicion is that there is a lack of boost pressure.


Maybe you can help me...


Regards,
Sven.

Hello,

Does this part have an engine control unit, or is it mechanically controlled?
OBD2? Does this part emit excessive exhaust fumes under full load, or not?

Best regards, Rainer.

Hello Rainer...

Ist komplett mechanisch. No ECU.

It also produces black smoke when running at full load. This points to a lack of air.
I would just like to get some target values regarding the boost pressure.
I already called Deutz, but they wouldn't give me any information.

Best regards,

Hello,

It's obviously a problem if you don't know the required charging pressure.

Here are some things you can check out of suspicion:
- Is the turbocharger pressure system (hoses, possibly intercooler) sealed? Oil mist/leakage indicates a leak.
- Wastegate closed?
- Does the turbine wheel have excessive play and rotate freely? Are the compressor and turbine wheels undamaged?

Best regards, Rainer.

Here's a brief explanation about the engine (it's not a VW engine).

BF8M1015C

It would therefore need to be an 8-cylinder engine with liquid cooling and two turbochargers.
Approximately 150 mm stroke.

I would check everything related to the speed control unit, including the turbocharger pressure sensor.

No, it's certainly not a "small VW engine"... It's a Deutz engine.

- 8-cylinder V engine.
- 15.874 cc
- Drilling 132mm
- Hub 145mm
- Compression ratio 17:1
- 348 kW at 2100 RPM
- 2350 Nm @ 1200 rpm

Okay, so this is what has now been reviewed.

- Komplettes Ladeluftsystem ; Mit 4 bar abgedrück.. Dense.
- Turbocharger; both with normal shaft play and no damage. Wastegate not included!

I must say, it's a Hitachi CX550 GLS type ram.

Hello,

How is the power being extracted from the motor? Does the motor truly have no power (does the speed drop under load), or is there a problem with the power take-off mechanism?

Best regards, Rainer.

The power is transmitted through a distribution gearbox that distributes the force to 11 hydraulic pumps. This includes 2 pumps with a capacity of 284 liters per minute at 380 bar, 3 pumps with a capacity of 87 liters per minute at 320 bar, and several smaller pumps for control oil pressure and the lighting system.

Last year around this time, an AT engine was installed. The first engine never had these problems. And the AT engine only started experiencing these issues in the last six months.
A hydraulic problem has been ruled out. The engine speed suddenly drops from 2100 to 1300 RPM as soon as it's under load. It remains like that until it becomes easier to shake or pull again.

Possibly Deutz will be involved next week. Let's see what they have to say about it.

Best regards,

I experienced a similar phenomenon with a forage harvester powered by a Mercedes V8 engine.
The problem back then was two clogged fuel filters. The inside of the tank was corroded, and it wasn't until I scrubbed it with a household scrubbing brush that it improved.
