Common Rail Fuel Injection: Key technology for clean and economical combustion

Pioneer of the common rail fuel injection system The emissions regulations for diesel engines in applications such as ships, trains and heavyduty off-road vehicles and gensets worldwide are becoming more stringent and make extensive modifications to the power units necessary. At the same time, customers are constantly calling for more economical engines. Exhaust after treatment systems such as SCR catalytic converters (selective catalytic reduction, short: SCR) or diesel particulate filters are one way of lowering emissions, but also have a greater space requirement and potentially increase the engine’s maintenance needs. For these reasons, MTU primarily pursues a policy of reducing emissions by internal engine enhancements. Fuel combustion inside the engine is improved so that, if at all possible, emissions are not produced in the first place. If necessary, MTU introduces a Engine technology
