The Limbach L1700 is a series of type certified German aircraft engines, designed and produced by Limbach Flugmotoren of Königswinter for use in light aircraft and motorgliders.[1]

The series were originally designated as the SL1700 under its former certification and was changed to L1700 by company Service Bulletin no. 17.[2]

Design and development[edit]

The L1700 is a four-cylinder four-stroke, horizontally-opposed air-cooled, gasoline direct-dive engine design, based upon the Volkswagen air-cooled engine. It employs a single magneto ignition, one carburettor, is lubricated by a wet sump and produces 50 kW (67 hp) at 3600 rpm.[1][3]

The L1700 was type certified by the European Aviation Safety Agency on 4 August 2006. The first engines in the series had originally been certified by the German Luftfahrt-Bundesamt (LBA) on 6 December 1971.[2]
