Compared to previous generation engines, MF's
electronic engine management system broadens the
operating range within which the tractor is operating at
optimum fuel efficiency.
Improved fuel economy
The Electronic Engine Management
system constantly monitors a
wide range of parameters and
makes continual and incredibly
fine adjustments to fuel injection.
Combined with high pressure
'common rail' fuel injection and
the 4-valve cylinder head design,
this has given further significant
improvements, not only in
emissions but also in fuel economy.

The upper curve clearly shows how maximum torque
is maintained between 1200 and 1500 rev/min, with
steep torque rise as engine revs fall between 2200 and
1500 rev/min. The lower curve shows high power, with
'constant power' maintained down to 1570 rev/min.
The cooling system
A highly efficient cooling system
ensures that the engine itself
works to its fullest capacity
regardless of the application.
The fully-vented bonnet allows
the engine to breathe even in
dusty, dirty conditions. A large air
filter maintains cleanliness within
the engine, allowing for higher
productivity and savings on fuel
consumption.
