Reliable SisuDiesel engines

N Series tractors are powered by Valtra’s fourcylinder 4.4 and 4.9 litre SisuDiesel engines. The 4.9 litre engine is based on the large 7.4 litre
long-stroke SisuDiesel engine. It therefore features many of the design advantages of the 7.4 litre engine. Torque has been increased by around 10 percent across the range compared to corresponding engines in previous models. Four N Series models feature Common Rail fuel injection and transport boost for extra power when needed. The range also features an efficient and economical EcoPower model.
 

SISUDIESEL ADVANTAGES
• Extremely durable and reliable
• 4.9 liter’s engine has many same components as
  7.4 litre’s SisuDiesel engine:
  - pistons, liners, connecting rod
• Low maintenance costs
  - 500-hour oil change intervals
• Best power-to-weight ratio among tractor engines
• Low fuel consumption
• Low heat load extends lifespan of engine
• Common Rail engines meet EU stage 3A and EPA
  Tier III emissions standards
• High torque at low revs
• Quiet and pleasant engine sound
• Excellent cold-start properties
 

Electronic engine management (EEM) enables the use of cruise control, which allows the driver to preset the ideal work speed according to either the driving speed or the PTO speed.
 

Common-Rail fuel injection (N101-N141)
Common Rail engines offer high levels of torque across a broad range of speeds, combined with low emissions and good fuel efficiency. CR engines work together seamlessly with the electronically controlled Powershift
transmission, maintaining low engine speeds and fuel consumption.

CR engines provide high fuel injection pressure regardless of engine speed. The fuel can be delivered in several stages during a single ignition, making the engine idle extremely smooth and pleasant to the ear. CR engines also react quickly to changes in load, creating a smoother ride and reducing the need to change gears. The high torque of CR SisuDiesel engines is achieved already at low revs, and torque levels remain high even if the revs drop while working. Maximum power is achieved already at 2000 rpm.
 

Low idle speed (650 rpm)
The low idle speed (HiTech and Advance) is a Valtra innovation.
When the tractor is parked and the handbrake engaged, the engine
speed drops to a pleasantly quiet 650 rpm.

Ecopower
The Valtra N111 EcoPower model offers fuel savings of 10-15 percent by lowering the engine speed. The average piston speed is 20 percent
slower than in regular engines. The lifespan of the engine is correspondingly extended. Wet cylinder liners and intercooling also extend the lifespan of
SisuDiesel engines. In practice, the Valtra N111 EcoPower model means significantly lower workhour costs, environmental friendliness and low
emissions. An added benefit is the reduction in engine noise by 4-5 decibels.
 

Two Tractors In One
New feature in EcoPower is the option to switch between the efficient Eco mode and the standard Power mode.
 

Ecospeed
EcoSpeed is based on the 50-km/h transmission, but the highest speed is limited to approximately 40km/h (max possible speed is 43km/h depending on load).

• Engine speed at max speed of 40 km/h is around 1800 rpm depending
  on tyre size
• Speed with H4, Delta PS 2nd gear: 40 km/h at 2200 rpm
• Speed with H4, Delta PS 3rd gear: 40 km/h at 1800 rpm
• Lower fuel consumption
• Lower noise, less wear
• Available for N111e-N141 models

Note that the speed chart for EcoSpeed models is the same as for 50-km/h models apart from the limitation in H4 to 40km/h.
