| Engine | Deutz TCD3.6 |
| Solution | Stage 1 Eco (AdBlue/SCR off* available on request) |
The situation
The Schaeff TW95 and TW110 are compact wheeled excavators that live on road and utility jobs: short cycles, frequent travel between positions and a lot of work on the hydraulics. Both series are built around the Deutz TCD3.6, an engine that is sized for the job but has no reserve to spare when the machine is loaded.
The dealer asked for a file that makes both machines more pleasant to work with: a little more power where the hydraulic pump demands it and, at the same time, a lower fuel bill.
What we did
The ECU was read and the file developed individually for the software version of each machine – the TW95 and the TW110 share the engine, but not necessarily the calibration.
- Stage 1 Eco: injection quantity, rail pressure and boost adjusted within the limits of the stock hardware, combined with an Eco calibration – a measured power increase and more usable torque under load, with the emphasis on fuel economy rather than peak output.
- AdBlue/SCR: available on request for both series – dosing and level monitoring can be deactivated in software* so that the machine no longer depends on DEF supply. This was not part of the job described here.
Checksum corrected and the file written to the ECU.
The result
More torque at the stick, a smoother response under load and lower fuel consumption at the same work rate. For the operator this means a compact excavator that handles trench and lifting work with less effort and fewer trips to the pump. Files for the Deutz TCD3.6 are developed from the original read of each machine – the software version decides what the file looks like.
