The EcoFit Single Module is designed to be up to 60% smaller and 40% lighter compared to the EPA 2013 solution it supersedes, all while improving emissions reduction performance. Since 2004, more than 1 million EcoFit DPFs have been put into use. A typical filter consists of an array of small channels for exhaust gas to flow.

The Fairbanks Morse Model 38 opposed-piston engine was designed and developed for a wide array of electrical power generation and heavy industrial applications. When equipped with Enviro-Design technology, Fairbanks Morse engines utilize pre-combustion chambers to reduce the quantity of pilot diesel fuel required for ignition.

For instance, intake/compression, combustion, expansion/exhaust are occurring simultaneously in separate chambers. Combining the high peak pressures produced during constant volume combustion with Atkinson expansion, which continuously extracts energy as exhaust gases expand to atmospheric pressure, delivers unprecedented fuel efficiency.

3B advantages shown in the lower load range up to 10 bar, consumption in the upper load range could also be significantly reduced. Audi initially deployed its turbocharged, direct injection TFSI technology in 2004; the second generation followed in 2007, followed by the third generation, currently on the market, in 2011.
