Exhaust Gas Recirculation: Internal engine technology for reducing nitrogen oxide emissions

Ways to reduce nitrogen oxide emissions One of MTU ś aims for its engines is to reduce the emission of soot particles and nitrogen oxides in order to achieve compliance with increasingly strict emissions regulations around the world. The main approach pursued by MTU is low-emission combustion, in other words an internal engine solution. However, this means taking into account a basic principle that governs the process of combustion — if the fuel burns at a higher temperature inside the cylinder, little soot is produced, but a large amount of nitrogen oxide. At lower combustion temperatures, nitrogen oxide emissions are low, but the production of soot Engine technology
