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.

La gestione elettronica del motore (EEM) consente l’uso del cruisce control, il quale permette al conducente di impostare la velocità di lavoro ideale, sia per il trasferimento che per la PTO.

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.
 
Eco Mode with genuine EcoPower features
• Rated speed 1800 rpm
• Fuel savings up to 10 %
• Lower noise level
• Lower piston speed, increased 
  engine life
• Very high torque, even at
  1000 rpm
• Wide, constant torque range

Eco Mode is recommended:
• For maximising fuel efficiency
• For soil preparation
• For all utility work
• For variable work
• For 540 PTO work  

Power Mode offering approximately the same power but including transport boost
• rated speed 2200 rpm
• Transport boost 11 hp (8 kW)
• Top speed 50 km/h or 40 km/h
  EcoSpeed depending on 
  specification
• High PTO power

Power Mode is recommended:
• For heavy PTO work
• For high average speeds in hilly
  conditions
• For high hydraulic output

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.
