Abstract

See full text

A method for operating a gas engine having an adjoining exhaust line through which exhaust line exhaust gas of the engine flows includes: operating the gas engine in accordance with a Miller cycle, such that a closing point of at least one intake valve of the gas engine is in a crank angle range of from about 50° of crank angle before bottom dead center (BDC) to about 10° of crank angle before BDC; and lowering, by at least one selective catalytic reduction (SCR) catalyst element in the exhaust line, a level of nitrogen oxides (NOx) in the exhaust gas flowing through the SCR catalyst element using hydrocarbons (CyHz) as a reducing agent. At least some of the hydrocarbons (CyHz) flowing through the SCR catalyst element are constituents of the exhaust gas of the gas engine.
