The efficiency and emission levels of our engines in industrial applications have now reached a stage that years ago seemed unattainable. The credit is due to the use of innovative technologies, including both internal engine enhancements and exhaust aftertreatment. The ability to meet new emission requirements when moving up to a more stringent exhaust gas standard requires more than just knowing how an engine ticks. Our approach is to successfully integrate the entire powertrain – this ensures that our drive systems deliver more. And consume less fuel. For a long, long time.
97.8% reduction in soot emissions over 19 years
The increasingly stringent emissions limits are fast approaching the ideal ‘zero emissions’ target for diesel engines. The statistics speak for themselves: Over the course of 19 years, EU emissions Stages have been tightened four times and EPA Tier regulations have been created to govern industrial engines. EU Stage V will be the fith time since Stage I (1996) that emissions limits have been tightened representing a cut of more than 94% in nitrogen oxides. At 97.8%, reductions in soot particulate emissions have been even greater.
Although nitrogen limits will remain at current levels, targets for soot particle emissions will be drastically reduced – by 40%, from 25 mg/kWh to 15.mg/kWh. For the first time, regulations will also be introduced to limit soot emissions not only in line with volume but also on the basis of the number of particles discharged (i.e. 9 x 1011 particles/kWh). This can only be achieved by using a diesel particulate filter.
