Abstract

There is described a nautical engine comprising at least one combustion chamber (1) provided with a first opening (11), normally closed by a first valve (12), for feeding the air and fuel mixture, at least one spark plug (20) for igniting the mixture, at least one second opening (14), normally closed by a second valve (15), for exhausting the exhaust gas deriving from the ignition of the mixture, means (2) adapted to feed at least one combustion chamber by means of said at least one first opening, a control device (30) adapted to control said feeding means for feeding the mixture into the combustion chamber and for igniting the spark plug for igniting the mixture. Said feeding means comprise a nozzle (30) adapted to spray said mixture at a pressure such as to open said first valve of the chamber, and in that, after having closed said first opening of the first valve, said second valve for exhausting the gas can be opened by the gas produced by the ignition of said mixture in the combustion chamber. The combustion chamber being integral with at least one propulsion tube (51) immersed in water and to which the gas from the combustion chamber leads for compressing and expelling the water present in at least one propulsion tube after having closed said second opening of the second valve.
