A dual-piston internal combustion engine

Abstract

The invention discloses a double-piston internal combustion engine which comprises a piston (1), an air cylinder (2) and an air cylinder cover (3), wherein the air cylinder cover (3) is arranged at the upper end of the air cylinder (2); a connecting rod is connected to the lower end of the piston (1); the connecting rod and a crankshaft are connected to form a piston crank connecting rod mechanism. The double-piston internal combustion engine further comprises a pressure sensor (11), a pressure strain piston (4), an air bag (5) and a stress piston (6); the pressure strain piston (4), the air bag (5) and the stress piston (6) are arranged in the air cylinder cover (3); one end of the stress piston (6) is supported against the lower part of the air bag (5); the other end of the stress piston (6) is connected with the pressure strain piston (4) through a connecting rod (8); a pressure relief pipe (12) and a pressurizing pipe (13) are respectively connected onto the air bag (5); normally-closed solenoid valves (10) are respectively arranged on the pressure relief pipe (12) and the pressurizing pipe (13). According to the double-piston internal combustion engine, the control over the combustion state and characteristics of the internal combustion engine is realized.
