Machine description
Diesel engine
The machine is equipped with a completely
electronically controlled water-cooled four-cylinder,
turbocharged (WGT) diesel engine with direct injection
(HPCR) and intercooler.
WGT - Waste Gate Turbo
HPCR - High Pressure Common Rail fuel injection
(IIIB/T4i)
The engine is also equipped with cooled exhaust gas
recirculation (ceGR) and electronically controlled
exhaust gas recirculation valves (EGR) together with a
Cummins ® diesel oxidation catalysator (DOC) system
for exhaust after-treatment.
The engine has also an electronically controlled
variable flow turbo (VFT) and crankcase ventilation
system with highly efficient coalesching filters.
ceEGR - External Cooled EGR-electronically controlled
DOC - Diesel Oxidation Catalyst
VFT - Variable Flow turbocharger-el. controlled
Electrical system
The machine has the following control units (ECU,
Electronic Control Unit) and electronic units.
• Main ECU (for the machine)
• Diesel engine control unit (ECM)
• I/O board (Control board)
• Display
Propulsion system
The propulsion system is a hydrostatic system
A drive unit (propulsion motor + gear) drives each
drum or wheel pair.
All propulsion motors are connected in parallel, a
hydraulic pump supplies all motors with hydraulic oil.
The speed of the machine is proportional to the angle
of the control lever (the deflection of the
forward/reverse lever regulates the speed). A speed
selector is available as option.
