Abstract

A double-crankshaft four-stroke engine comprises an air cylinder provided with an air inlet and an air outlet. A piston is arranged in the air cylinder. The bottom of the piston is connected with a first crankshaft. The first crankshaft is connected with an output gear through a second crankshaft. When the engine operates, the air inlet stroke and the compression stroke of the engine are different from the acting stroke and the exhaust stroke of the engine. Compared with a traditional engine, the double-crankshaft four-stroke engine has the advantages that under the condition that the air inlet stroke and the compression stroke are the same, the acting stroke of the piston of the engine is larger than that of a piston of the traditional engine, and energy in the air cylinder is fully utilized at the moment.

Description

technical field [0001] A double crankshaft four-stroke engine belongs to the field of engines. Background technique [0002] The current engines have insufficient energy utilization, low working efficiency and thermal efficiency, high fuel consumption and low fuel utilization rate, and the existing engine pollution control is not ideal, and the exhaust noise is slightly louder. Contents of the invention [0003] Purpose of the invention: [0004] The invention provides a double-crankshaft four-stroke engine, and its purpose is to solve the existing problems in the past.
