Abstract
The invention relates to the field of engines, and particularly discloses a double-cylinder gasoline engine with opposed pistons. The double-cylinder gasoline engine mainly comprises air cylinders, a crankshaft box, a crankshaft, connecting rods, the pistons and a valve mechanism. The crankshaft is located in the crankshaft box, the pistons are located in the air cylinders, the pistons and the crankshaft are connected through the connecting rods, and the air cylinders are located on the two sides of the crankshaft box respectively. The crankshaft box comprises an upper crankshaft box body, a lower crankshaft box body and a crankshaft box base, wherein the upper crankshaft box body and the lower crankshaft box body are detachably connected. The crankshaft box base can rotate within the range from 0 degree to 90 degrees. The double-cylinder gasoline engine has the advantages that due to the adoption of the structure, the thermodynamic cycle of gas is achieved relying on the reciprocating of the pistons in the air cylinders, and the movement is converted into rotating movement of the crankshaft through the connecting rods so that the chemical energy of fuel can be converted into mechanical energy; the crankshaft box base can rotate within the range from 0 degree to 90 degrees, and therefore the change of the installation method of the whole engine is achieved, and different use requirements are met.
