Agricultural / Off Road
Agricultural
and off-road engines and vehicles see a heavy duty-cycle in a harsh
environment nearly every day of their existence. These
engines must operate in temperature ranges from artic conditions to
daily operating temperatures up to 120°F, depending upon their
market. Some markets require engines that are designed to both
propel the vehicle and operate attachments like buckets, blades and
shovels found on farming and construction equipment. Agricultural
and off-road engines also experience a tremendous range of exhaust gas
temperatures, since most of them operate at low speeds. In some
markets diesel fuel is the fuel of choice. Yet today, the
diversity of fuels in the market is increasing, not decreasing.
Manufacturers must prepare products for these markets, as well.
We can help. Powertrain design and development engineers must consider these environmental variables
when they develop new concepts and when product modifications are considered.
For
many years, this market was unregulated, allowing the manufacturer
significant freedom to design and develop simple, robust designs that
could continually fulfill their roles, independent of the harsh
environments into which they were placed.
The last decade has
brought regulations and new market drivers for emissions and noise
reduction, in particular, which have changed the equation. The
new Tier 4 regulations will provide more than a 90 percent reduction in
NOx and more than a 95 percent reduction in PM compared to uncontrolled
levels. Urban crowding has dramatically increased
sensitivity to noise from construction, agricultural and other off-road
equipment.
In some cases, the technology that is
necessary to achieve these goals introduces some complications.
For example, engineering the placement of the aftertreatment system is
difficult due to the significant space restraints presented by the
engine compartment size and packaging due to safety, visibility and
functionality requirements.
The duty-cycles and environments
have not changed, but agricultural and off-road powertrains are more
sophisticated than they have ever been. And along with
sophistication, has come concerns about durability, reliability,
maintenance and warranty claims. 
FEV’s engineers are well-prepared to support our customers in addressing these needs. We apply the latest tools to help our customers to develop world-class engines that meet all of their design targets for performance, emissions, and NVH. We also understand the cost-sensitivity of this market and continually find innovative ways to reduce product cost and improve quality, reliability and durability.
