Engine for The agricultural equipment 32 - 128 kW / 43 - 172 hp

These are the characteristics of the 912/913:

Air-cooled 3- to 6-cylinder naturally aspirated in-line engines.
4- and 6-cylinder 913 turbocharged, 6-cylinder also charge air cooled.
Advanced direct injection and combustion system.
Electronic governor on request.
100% PTO possibilities at flywheel and damper end.
Auxiliary PTOs for hydraulic pumps and compressor possible.
Enormous traction through high torque backup.
Thanks to sophisticated modular system high degree of parts commonality.
Extremely compact dimensions.

Your benefits:
Noise-optimized technology reduces insulation requirements and increases driving comfort.
Despite uprating high operating economy. Long service intervals, ease of service and low consumption
values reduce operating costs.
Space-saving design guarantees low installation space requirement. This in turn promotes the compact-
ness of agricultural implements and enhances your competitive advantage in your markets.
Logistic advantages and thus cost savings thanks to sophisticated modular system.
All engines fulfill current exhaust emission standards. And they have the potential for meeting future
exhaust emission standards via suitable provision for installation of advanced injection systems with no
changes to installation envelope.
