Double-cylinder symmetrical horizontal engine

The utility model relates to a double-cylinder symmetrical horizontal engine, which is the improvement of an upright single-row engine changed into a horizontal engine. The utility model mainly solves the problems of a cylinder and a piston of the upright engine having severe abrasion, air pressure ratio, low power, short major repair mileage, etc. The utility model adopting a double-cylinder symmetrical horizontal engine is composed of a cylinder body, a cylinder, a crankshaft, a connecting rod piston, etc., wherein, the crankshaft is provided with a slide way at a symmetrical shaft line, both ends of the crankshaft are provided with columns, and both sides of the crankshaft are provided with symmetrical rectangular lug bosses with connecting rod magnetic poles. An end head is fixedly connected with the piston, the cylinder body is provided with a cylinder body magnetic pole, and a like pole corresponds to the connecting rod magnetic poles. A crank pin of the crankshaft is arranged in the slide way, a slide block is arranged on the crank pin, the connecting rod can generate thrust force to drive the crankshaft to rotate in order to output torque due to the combustion of fuel. The utility model has the advantages that the friction of the cylinder and the piston is reduced due to the horizontal cylinder, the service life of the engine is prolonged, and exhaust is improved. The double-cylinder symmetrical horizontal engine is a superior device for vehicular power.
