Investigating the Influence of Water Injection on the Emissions of a Diesel Engine

There are many methods to decrease the nitrogen oxide emissions of a diesel engine. One promising measure is water injection into the engine’sintake manifold. As emission limits become more and more stringent, the diesel engine NOx–particulate trade-off is a challenge for engine developers. To overc...
