Abstract
Method and system for operating a compression engine on ether containing fuel obtained by conversion of a primary fuel based on alcohol comprising the steps and means for: (a) continuously withdrawing the primary fuel based on alcohol from a fuel tank and pressurising the primary fuel based on alcohol in its liquid form to a final engine injection pressure; (b) continuously introducing the pressurized primary fuel based on alcohol into a fuel accumulation chamber; (c) continuously distributing the pressurized primary fuel based on alcohol into pipes connecting the accumulation chamber with fuel injectors of the engine; (d) prior to the fuel injectors continuously converting the pressurised primary fuel based on alcohol to an ether containing fuel by contact with an alcohol dehydration catalyst being arranged in each of the pipes upstream the fuel injectors; (e) continuously injecting the ether containing fuel at injection pressure into the engine; and (f) continuously withdrawing a part of the introduced primary fuel based on alcohol from the accumulation chamber; and (g) depressurising and recycling the withdrawn primary fuel based on alcohol to the fuel tank.
