Exhaust aftertreatment methods,e-way catalytic converters are used with conventional spark-ignition engines, diesel engines are fitted with oxidation catalysts and will, in the future, probably also feature particulate traps. Denox or lean-burn catalytic converters that are currently under development would be suitable both for s

Problems with CO2 emissions,pogenic emissions, i.e. emissions from technology systems created by man, will be considered. These emissions essentially are the result of energy conversion processes. Approx. 750 million tons of carbon dioxide were emitted in Germany (without the former East German territory), corresponding to 3.6

Laws regulating the emission of pollutants and maximum fuel consumption of combustion engines (as oto the introduction of measures to limit pollutant emissions . To ensure reproducibility and comparability, the emitted pollutant quantities are determined according to specified test methods. One drawback is that test methods, classifications and emission standards often di

Exhaust aftertreatment methods,re, probably also feature particulate traps. Denox or lean-burn catalytic converters that are currently under development would be suitable both for sparkignition engines (lean-burn engines) and for diesel engines. Lean-burn catalysts offer acceptable conversion efficiencies, especially of NO., in the λ > 1 range.
