Without countermeasures, the increasing use of methane as a fuel in four-stroke gas engines operating on the Otto cycle could substantially increase the amount of a potent greenhouse gas reaching the atmosphere. A team from the University of Rostock has investigated the potential for methane slip reduction by locating the catalytic converter ahead of the turbocharger turbine, where exhaust temperatures and pressures are close to their highest. This article is based on a paper presented at the 9th International MTZ Conference on Heavy-Duty, On- and Off-Highway Engines 2014 in Saarbrücken (Germany).

Motivation

Under tightening emissions limits, natural gas becomes an increasingly interesting fuel for on- and off-highway engine applications currently covered by diesel engines. Compared to diesel fuel operation, the application of natural gas allows a decrease in emissions of particulate (PM) and oxides of nitrogen (NOx). Likewise emissions of carbon dioxide (CO2) are lower due to the...
