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/T4f)
The engine is also equipped with cooled exhaust gas
recirculation (ceGR) and a diesel oxidation catalysator
(DOC) system for exhaust after-treatment.
The engine has also an electronically controlled
variable flow turbo (VFT) and closed crankcase
ventilation.
ceEGR - External Cooled EGR-electronically controlled
DOC - Diesel Oxidation Catalyst
VFT - Variable Flow turbocharger-el. controlled
(stage V)
The engine is also equipped with cooled exhaust gas
recirculation (ceEGR) and a diesel particle filter (DPF)
system for exhaust after-treatment.
The engine has also an electronically controlled
variable flow turbo (VFT) and closed crankcase
ventilation.
ceEGR - External Cooled EGR-electronically controlled
DPF - Diesel particle filter
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.
Machines with split drum/s has a drive unit per drum
half and an anti-spin system.
All propulsion motors are connected in parallel, a
