Machine description
Diesel engine, Cummins
The machine is equipped with a water-cooled, straight
four-cylinder, four-stroke, turbocharged diesel engine
with direct injection and a charge air cooler.
(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.
Diesel engine, Deutz
The machine is equipped with a water-cooled, straight
six cylinder, four-stroke, turbocharged diesel engine
with direct injection and a charge air cooler.
(IIIB/T4i)
The engine is also equipped with external exhaust gas
recirculation (EGR) and a system for after-treatment of
exhaust fumes (DPF-Diesel Particle Filter).
Exhaust afterburn system (regeneration) (IIIB/T4i)
To minimize particles and hydrocarbons, the engine is
fitted with a diesel particle filter, as well as a control
unit for after-treatment of exhaust fumes. The diesel
particle filter incorporates active burnout.
When the engine is running, particles are collected in
the DPF, and the particles have be burned away in
order to clean the filter.
During the burnout/regeneration process, the exhaust
gas temperature increases significantly above the
normal temperature in the exhaust pipe.
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/Transmission
The propulsion system is a hydrostatic system with a
hydraulic pump supplying two motors connected in
parallel, one for the rear axle and one for the drum.
