Introduction
The M57TU TOP diesel engine is redesigned.
The M57TU2 TOP with 2-stage turbocharging is used as the most powerful diesel engine.
1 small and 1 large turbocharger are used for 2-stage turbocharging.
The M57TU2 TOP can be recognised by the changed arrangement of the turbochargers.
The increase in power output is 10 kW/14 hp.
In addition, the M57TU2 TOP now has injectors with piezo-elements.
The M57TU2 TOP is distinguished by its extraordinary power output characteristics.
-
High torque at low engine speeds: Good response with impressive pulling-away dynamics
-
Usable rpm range extended upwards: High output yield at low engine speeds
The power output is 210 kW/286 hp.
Peak torque of 580 Nm is achieved at 1750 rpm.
In 1st, 2nd and reverse gears, torque is limited to 500 Nm.
[system overview ...]
The 2-stage turbocharging is new for a series-production vehicle. It is familiar from high-power engines in boats.
The maximum boost pressure for the entire system is 2.95 bar. The maximum turbine speed is 205,000 rpm for the
small turbocharger and 150,000 rpm for the large turbocharger (physical limits). The actual turbine speeds are lower.
A further advantage of the 2-stage turbocharging is the use of robust turbochargers.
