Vehicle Development Insights from Industry: Technologies and Trends for Future Growth - Tier 4 Final and beyond

The off-highway equipment industry is facing the challenges that go along with integrating new ultra-clean emissions machines through the Tier 4 Final regulations that extend through 2014. This clear path to reduce emissions with Tier 4 Interim regulations starting in 2011 required companies to look beyond engine technologies such as high-pressure fuel systems, engine timing, combustion, turbocharging, and electronics to aftertreatment innovations.

These innovations not only help to meet the latest regulations, but can also lead to more fuel-efficient products that produce less CO₂ in the future. Looking beyond Tier 4 Final regulations, one can assume technologies such as onboard diagnostics, telematics, various hybrid systems, or waste-heat-recovery methods will become more common in our industry as we look toward the future of efficient diesel power.
