“…The comparative analysis of catalytic properties of Group 11 elements in NO x reduction by hydrocarbons in the presence of oxygen ammonia reduction (NH • 3 -SCR) In the NH • 3 -SCR systems, gaseous ammonia can be released from ammonia sorbents or by ammonium salt decomposition and can be introduced into the exhaust gases at any temperature, especially at low loads of the combustion engine [9]. In the case of SCR reactors active at a low temperature, NO •…”

NOx emission reduction in diesel engines can be achieved by using catalytic reactors reducing nitrogen oxides, including NH3-SCR and possibly also HC-SCR reactors. Reactors using ammonia achieve large conversion rates but cause a lot of operational problems. For this reason, the interest in reactors using hydrocarbons and their derivatives to reduce NOx has increased. Such reactors are the ones using metals from Group 11 (coinage metals) such as Cu, Ag and Au placed on an Al2O3-SiO2 carrier as active materials. The article characterizes the porosity and acidity of the carrier surface. Conversion of NO2, NO and propene as well as the formation of CO and N2O depending on the temperature at constant dosing of propene on a carrier covered with Cu, Ag and Au with a metal content of 4 g/dm3 were evaluated. The results of the tests showed that the tested Group 11 elements can be the basis for further experiments related to the development of this exhaust fumes cleaning technology for diesel engines.

The operating conditions of injectors in spark ignition engines with direct fuel injection make them susceptible to coking, which leads to a reduced quality of fuel atomization. This can be observed by a drop in performance and an increase in exhaust emissions, especially particulate matter. One effective method of reducing injector coking is by using detergentdispersing gasoline additives. The article describes the effect of using an admixture with a varied alcohol content on the quantitative and qualitative fuel atomization indicators. The research consisted of a 48-hour engine test, done in accordance with the CEC F-113-KC procedure (CEC-F-113 test). After each test cycle, the injectors underwent optical tests with the use of an isochoric chamber. The spray penetration and surface area were analyzed at a set of different fuel injection parameter values. The research performed resulted in determining the influence of each tested admixture on the change of injection time and on the geometric indicators of the fuel spray. The obtained characteristics of the engine in operation and conducted stationary tests enabled the operational evaluation of the impact an alcohol admixture with gasoline fuels had on key engine parameters.
