Summary

Between 2011 and 2015, permissible levels of exhaust emissions for off-highway engines in Europe and in the USA will again be significantly reduced. Legislation covering the various applications and power ranges is extremely diverse. Engine manufacturers are responsible for developing different emissions-reduction methods for the individual markets in order to provide optimum solutions in areas such as fuel consumption and CO2 emissions. This article describes some of the technical concepts, both current and planned, which MTU Friedrichshafen will employ to align its present engine series with future legislation. Basicconfiguration engines are being toughened to withstand high ignition and injection pressures and further development is ongoing on cooled exhaust gas recirculation, the Miller process and 2-stage turbocharging...
