Valtras N111e and T151e EcoPower tractor models fully utilise the sturdiness and high-torque characteristics of SisuDiesel engines at low revs. Compared with standard engines, the engine speed has been reduced by 400 rpm while maintaining maximum torque in this range. This reduces fuel consumption by up to 10 percent. At the same time, the transmission and hydraulic pumps also operate at lower speeds, which reduces power losses and lowers costs in relation to the horsepower produced.
Benefits of low rev engines:
Rated speed of 1800 rpm
Low operating speed
Max. torque at 1100/1200 rpm
Very high torque, even at 1000 rpm
Wide constant torque range
Low fuel consumption, approx.10 % lower than engines with similar output
Low emissions
Lower noise levels
Less waste oil
Less vibrations
Low piston speed: longer engine life
Long oil change intervals
