On the issue of reducing the content of nitrogen oxides in a diesel engine by organizing its workflow
Abstract
Currently, sufficiently effective systems for neutralizing nitrogen oxides (NOx) for diesel engines have not been developed. The systems used on diesel cars make it possible to obtain neutralization efficiency of 60 ... 70% on average. The designs used do not allow to increase their efficiency above what has already been achieved. With the use of modern fuel injection systems with electronic control, it is possible to implement the process of neutralization of nitrogen oxides when ammonia (NH3) is injected into the combustion chamber at the exhaust stroke. Given that NH3 can form NOx during combustion, it must be fed into the diesel cylinder under certain temperature conditions. Thus, its injection at relatively low temperatures (700 ... 900°C) will contribute to the effective course of nitrogen reduction reactions from NOx.
