Badania modelowe układu katalitycznego oczyszczania spalin silnika o zapłonie samoczynnym

The article addresses the problems of exhaust gases emitted by combustion engines non-road vehicles, which must meet the requirements of the Stage IV standard. Research was carried out for the diesel engine medium-power of agricultural tractor. Obtained results showed that catalytic efficiency is affected by engine load to the greatest extent. In the range of low loads the applied exhaust aftertreatment system was ineffective in terms of hydrocarbons oxidation as well as reduction of nitrogen oxides.
