Taking the connection between the first cylinder 1 and the first driving wheel 1-1 as an example for description, as shown in fig. 2, the piston rod of the first cylinder 1 is connected to one side of the first driving wheel 1-1 through the connecting cross rod, and the first driving wheel 1-1 is an incomplete gear, so that when the piston moves up and down, the piston rod and the connecting cross rod can drive the first driving wheel 1-1 to rotate.
In this embodiment, as shown in fig. 1, the first driving wheel 1-1 and the second driving wheel 2-1 are coaxially disposed and connected by a first wheel axle 6, the third driving wheel 3-1 and the fourth driving wheel 4-1 are coaxially disposed and connected by a second wheel axle 7, and the power output wheel 5 is disposed on the second wheel axle 7 in a penetrating manner.
Specifically, the first driving wheel 1-1 is meshed with the third driving wheel 3-1 through a first driving wheel 101, the second driving wheel 2-1 is meshed with the fourth driving wheel 4-1 through a second driving wheel 102, the first driving wheel 101 and the second driving wheel 102 have the same size, and the diameter of the driving wheel is smaller than that of the driving wheel.
In this embodiment, the first driving wheel 1-1, the second driving wheel 2-1, the third driving wheel 3-1 and the fourth driving wheel 4-1 are all provided with one-way bearings, the one-way bearings are arranged on the first driving wheel 1-1, and when the first driving wheel 1-1 rotates, the one-way bearings lock the first wheel shaft 6, so that the first wheel shaft 6 generates torque force, the first wheel shaft 6 can be driven to synchronously rotate, and the second driving wheel 2-1 is driven to rotate; the third driving wheel 3-1 and the fourth driving wheel 4-1 have the same principle.
In order to transmit the torque force on the first wheel shaft 6 and the second wheel shaft 7 to the power output wheel 5, a first power rotating wheel 103 is coaxially arranged between the first driving wheel 1-1 and the second driving wheel 2-1, and a second power rotating wheel 104 is coaxially arranged between the third driving wheel 3-1 and the fourth driving wheel 4-1, namely, the first power rotating wheel 103 is arranged on the first wheel shaft 6 in a penetrating way, the second power rotating wheel 104 is arranged on the second wheel shaft 7 in a penetrating way, and the first power rotating wheel 103 is meshed with the second power rotating wheel 104.

In the present embodiment, the first cylinder 1, the second cylinder 2, the third cylinder 3, and the fourth cylinder 4 are operated in a differential stroke, that is, when the first cylinder 1 is in a power stroke, the second cylinder 2 is in an intake stroke, the third cylinder 3 is in a compression stroke, and the fourth cylinder 4 is in an exhaust stroke.
Specifically, as shown in fig. 1 and 2, when the piston of the first cylinder 1 is located at the top dead center position, the gas is combusted to release energy, and the piston is pushed to do work downwards to drive the first driving wheel 1-1 to rotate anticlockwise, because the first driving wheel 1-1 is provided with the one-way bearing, the one-way bearing locks the first wheel shaft 6 to drive the first wheel shaft 6 to rotate, and the second driving wheel 2-1 is also provided with the one-way bearing, therefore, the first wheel shaft 6 rotates to drive the second driving wheel 2-1 to rotate anticlockwise to further drive the piston of the second cylinder 2 to move downwards, that is, the second cylinder 2 enters an air intake stroke, and at this time, the pistons of the first cylinder 1 and the second cylinder 2 are both located at the bottom dead center position. In this embodiment, the one-way bearing on the first driving wheel 1-1 will lock the first wheel axle 6 and drive the first wheel axle 6 to rotate only when the piston of the first cylinder 1 moves downward.
When the first driving wheel 1-1 rotates anticlockwise, the third driving wheel 3-1 rotates anticlockwise under the transmission of the first driving wheel 101 to drive the piston of the third cylinder 3 to move upwards, namely the piston of the third cylinder 3 moves towards the top dead center to compress gas, and the gas starts to burn under the action of the spark plug; when the second driving wheel 2-1 rotates counterclockwise, the fourth driving wheel 4-1 rotates counterclockwise under the transmission of the second transmission wheel 102, and drives the piston of the fourth cylinder 4 to move upward for exhausting, that is, the third cylinder 3 is in the compression stroke at this time, and the fourth cylinder 4 is in the exhaust stroke.
Because the wheel shaft can be locked only when the piston moves downwards, when the piston of the first cylinder 1 moves downwards, the first wheel shaft 6 is driven to rotate anticlockwise, the second wheel shaft 7 does not rotate, the first wheel shaft 6 rotates to drive the first power rotating wheel 103 to rotate, the first power rotating wheel 103 transmits power to the power output wheel 5 through the second power rotating wheel 104, and thus, one wheel does work.
After the upper wheel finishes acting, when the piston of the third cylinder 3 is positioned at the top dead center position, the upper wheel starts to enter an acting stroke, the gas is combusted to release energy, the piston is pushed to do work downwards, the third driving wheel 3-1 is driven to rotate clockwise, the second wheel shaft 7 is driven to rotate synchronously under the action of the one-way bearing, the fourth driving wheel 4-1 is further driven to rotate clockwise, the piston of the fourth cylinder 4 moves downwards, namely, at the moment, the third cylinder 3 is positioned in the acting stroke, and the fourth cylinder 4 is positioned in an air inlet stroke.
When the third driving wheel 3-1 rotates clockwise, the first driving wheel 1-1 rotates clockwise under the action of the first driving wheel 101 to drive the piston of the first cylinder 1 to move upwards to compress fuel gas; when the fourth driving wheel 4-1 rotates clockwise, the second driving wheel 2-1 rotates clockwise under the action of the second driving wheel 102, so as to drive the piston of the second cylinder 2 to move upwards, and at this time, the second cylinder 2 is in an exhaust stroke.
At this time, the piston of the third cylinder 3 moves downwards to drive the second wheel shaft 7 to rotate clockwise, the first wheel shaft 6 does not rotate, the second wheel shaft 7 rotates to directly transmit power to the power output wheel 5, and the above circulation is carried out, so that continuous power output can be realized.
