off-highway 2020: Emissions free?

Executive Viewpoints-Vehicle Development Insights from Industry: Off-Highway 2020 and Beyond-off-highway 2020: Emissions free?

The most significant challenge in the evolution of off-highway diesel engines will be compliance with future exhaust gas emissions limits while also achieving low fuel consumption and low CO₂ emissions.

Imagine being a student getting ready to take an important engineering exam. Your professor hands out the exam and you find that there is only one problem. To pass the class, you must design a diesel engine that can fit in the specified envelope, generate a massive amount of power, operate for upwards of 20,000 h before overhaul, burn less fuel than any previous model, be easily serviceable, and emit only harmless substances into the environment. While this is not a real test problem on an engineering exam, it is a real-life challenge that diesel manufacturers will have to grapple with in the not-so-distant future.
