controlled water-cooled, four-cylinder, turbocharged
(WGT) diesel engine with direct injection (HPCR).
WGT - Waste Gate Turbo
HPCR - High Pressure Common Rail fuel injection
(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)
• Safety ECU (steering/forward drive)
• Diesel engine control unit (ECM)
• I/O board (Control board)
• Display
Propulsion system
The propulsion system is a hydrostatic system
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
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). The speed
selector is standard equipment.
