To fulfill the substantially lower limits of future emission requirements, additional technologies will be necessary for engine development. These include, for example, so-called SCR (selective catalytic reduction) systems in which nitrogen oxides are reduced by means of ammonia. Hug has been gathering experience in this specialist field over many years and has developed and supplied around 1000 SCR systems for retrofitting on diesel engines in locomotives, ships and industrial plants.
Setting out the future course, Dr. Gerd-Michael Wolters, Member of the Tognum Board of Management responsible for Technology & Operations explained "In the next few years, we will be working with Hug to develop MTU-specific filter and SCR technologies through to standard-production maturity". The optimization of costs, installation space and weight will play a significant role in this process. "From 2011, we will be ready for standard production."
