INGAS “24 Months Meeting ”, “Brussels, Belgium”, “27-28 October 2010” INGAS INtegrated GAS Powertrain 2 WPA1.4 (after treatment system development) –Planned objectives & starting point The activity will lead to the definition of a dedicated solution for the aftertreatment system, taking into account fuel characteristics and engine specificities (lay out and operating modes). This will be supported in a first step both by the catalyst modelling and by laboratory tests, which will be followed by screening activities at the engine test bed. Starting from the engine characteristics and emission targets, new catalyst formulations will be evaluated at laboratory scale and proposed within different lay out solutions. Progress of work months –Sample preparation for engine tests at IFP –Ageing of the samples –Further lab. and own engine tests for washcoat development InGas 24 months meeting: SPA1/Ecocat
