40 Barsanti, Eugenio
SUBJECT AREA: Steam and internal combustion engines[br]b. 1821 Italyd. 1864 Liège, Belgium[br]Italian co-inventor of the internal combustion engine; lecturer in mechanics and hydraulics.[br]A trained scientist and engineer, Barsanti became acquainted with a distinguished engineer, Felice Matteucci, in 1851. Their combined talents enabled them to produce a number of so-called free-piston atmospheric engines from 1854 onwards. Using a principle demonstrated by the Swiss engineer Isaac de Rivaz in 1827, the troublesome explosive shocks encountered by other pioneers were avoided. A piston attached to a long toothed rack was propelled from beneath by the expansion of burning gas and allowed unrestricted movement. A resulting partial vacuum enabled atmospheric pressure to return the piston and produce the working stroke. Electric ignition was a feature of all the Italian engines.With many successful applications, a company was formed in 1860. A 20 hp (15 kW) engine stimulated much interest. Attempts by John Cockerill of Belgium to mass-produce small power units of up to 4 hp (3 kW) came to an abrupt end; during the negotiations Barsanti contracted typhoid fever and later died. The project was abandoned, but the working principle of the Italian engine was used successfully in the Otto-Langen engine of 1867.[br]Bibliography13 May 1854, British Provisional Patent no. 1,072 (the Barsanti and Matteucci engine).12 June 1857, British patent no. 1,655 (contained many notable improvements to the design).Further ReadingThe Engineer (1858) 5:73–4 (for an account of the Italian engine).Vincenzo Vannacci, 1955, L'invenzione del motore a scoppio realizzota dai toscani Barsanti e Matteucci 1854–1954, Florence.KAB
