Problems solved by technology
When the torque increases, the gas pressure is greatly reduced, so the power loss is large
[0003] In order to solve the above-mentioned technical problems, an opposed dual-piston engine is provided in the prior art, which includes two opposed pistons sharing a combustion chamber and crank-rod structures corresponding to the two pistons respectively. In response to changes in gas pressure or torque, the number of action arms for power output is increased, and at the same time, twice the transmission mechanism will affect the driven parts that cooperate with the engine, so the application of this solution is limited.

Description
technical field [0001] The invention belongs to an internal combustion engine system with a combustion chamber of a special shape or structure to improve operating performance, and in particular relates to a double-piston internal combustion engine cylinder system. Background technique [0002] Many engines used in today's various power equipment are internal combustion engines, and internal combustion engines are mostly fuel combustion in the cylinder to drive the cylinder piston to reciprocate. Because the horizontal thrust of the piston in this structure must be decomposed into the tangential force of the power transmission wheel, there is a situation that when the gas pressure is maximum, the torque is minimum. When the torque becomes larger, the gas pressure is greatly reduced, so the power loss is very large. [0003] In order to solve the above-mentioned technical problems, an opposed dual-piston engine is provided in the prior art, which includes two opposed pisto...
