Optionally, as shown in fig. 30, the cross cylinder further includes a cylinder connection joint 7, the cylinder connection joint 7 includes a circular disc 7-1 and four positioning columns 7-2, the four positioning columns 7-2 are installed on two sides of the circular disc 7-1, a connection line between the two positioning columns 7-2 on two sides of the circular disc 7-1 passes through a circle center of the circular disc 7-1 and has an included angle, and the positioning columns 7-2 are used for being inserted into the first insertion holes 5-21 on the first cylinder connection shaft 5-8 or the second insertion holes 6-25 on the second cylinder connection shaft 6-11. The degree of an included angle between connecting lines of the two positioning columns 7-2 on the two sides of the disc 7-1 is determined according to the number of the cross cylinders. For example, when four cross cylinders are arranged in an engine and an intake stroke, a compression stroke, a power stroke and an exhaust stroke are respectively completed in the same time period, the included angle of a connecting line between two positioning columns 7-2 on two sides of a disc 7-1 is 45 degrees.

In order to facilitate understanding of the method of using the present invention, the following description will exemplify the method of using the present invention by taking four cross cylinders configured in the engine as an example. First, four cross cylinders are assembled into the structure shown in fig. 31, that is, the four cross cylinders are connected by three cylinder connecting joints 7, wherein the first cross cylinder is displaced by 45 ° from the second cross cylinder, the third cross cylinder is at the same angle as the first cross cylinder, and the fourth cross cylinder is displaced by 45 ° from the third cross cylinder.

As shown in fig. 32, the operation of the engine at this time is as follows:

the working process of the suction stroke is as follows: after the exhaust stroke is finished, the valve 5-13 is in an open state, at the moment, the piston track roller 2-3 moves to the involute surface of the piston track 4-2 relatively, the four piston bodies 2-1 are separated outwards by the rotation of the flywheel 4, negative pressure is generated in the cross cylinder, and air is sucked into the cross cylinder. In the drawing of the suction stroke of fig. 32, the dark area is the involute surface of the piston track 4-2, and the flywheel 4 rotates to pull the piston body 2-1 outwards through the involute surface of the piston track 4-2, thereby sucking air.

The working process of the compression stroke is as follows: after the air suction stroke is finished, the air valve 5-13 is closed, oil injection is started, meanwhile, the piston track roller 2-3 moves to the gradually approaching surface of the piston track 4-2 relatively, and the four piston bodies 2-1 are close to the center of the cylinder shell 1 and pressurize air. At the end of this stroke, the fuel injection spark plug 6-2 ignites and begins to enter the power stroke. In the compression stroke of fig. 32, the dark area is the progressive surface of the piston track 4-2, and the rotating flywheel 4 presses the piston body 2-1 through the progressive surface of the piston track 4-2.

The working process of the power stroke is as follows: the gas in the cross cylinder expands to push the four piston bodies 2-1 to move towards four directions, and as the piston track rollers 2-3 are in sliding contact with the piston track 4-2, the four piston bodies 2-1 have kinetic energy of outward impact on the gradually-opened surface of the piston track 4-2, and the direction of the outward force of the piston is converted by the gradually-opened surface of the piston track 4-2 to become the rotation of the flywheel 4. In the power stroke of fig. 32, the dark color region is the involute surface of the piston track 4-2, the piston body 2-1 extrudes the involute surface outwards, and the flywheel 4 rotates due to the included angle relationship between the moving direction of the piston body and the involute surface.

The working process of the exhaust stroke is as follows: after the power stroke is finished, the valve valves 5-13 are opened, and because the flywheel 4 rotates after the power stroke, the piston track roller 2-3 rotates to the approaching surface of the piston track 4-2, the four piston bodies 2-1 are extruded to approach to the center, and waste gas is discharged. In the exhaust stroke of fig. 32, the dark area is the progressive surface of the piston track 4-2, the flywheel 4 rotates to press the piston body 2-1 through the progressive surface, and the exhaust gas is exhausted.

The utility model discloses in, air inlet and gas vent design are same mouthful, inlet and outlet 1-1 promptly, like this, and the entering of intake stroke low temperature air makes air flue and air valve 5-13 can not be because of the exhaust high temperature waste gas of exhaust stroke high temperature. During the compression stroke and the power stroke, the valve 5-13 is closed, and the compressed air in the air inlet passage 5-19 is continuously discharged from the air outlet passage 5-20, so that the temperature of the air outlet passage for discharging high-temperature waste gas is reduced by 5-20 ℃.

Further, when gasoline is used as a fuel, the ignition point of gasoline is 427 ℃, so that ignition by a spark plug is required, 14.7:1 is an air-fuel combustion ratio of air and gasoline mixture. However, engines constructed by the present invention can be designed with air-fuel ratios greater than this ratio, i.e., "lean". The utility model discloses well spark plug and fuel sprayer design are in the same place, and the last journey spark plug that directly spouts in the jar ignites, and what can realize like this, the air-fuel ratio of the mixed gas is far greater than 14.7:1 in the jar, nevertheless is being close to mixed gas concentration less than or equal to 14.7 around the spark plug: 1, normal ignition can be realized, and other low-concentration mixed gas far away from the spark plug in the cylinder can be ignited; the engine control module controls the high-pressure oil pump by combining the design of the oil injection elastic sheet 6-8 and the oil injection hole 6-13 in the design, the injected oil mist is from small to large, the oil injection quantity reaches the maximum at the end of a compression stroke, the mixed gas near the periphery of a spark plug reaches the ignition concentration, and the oil mist is ignited before reaching the cylinder wall, so that the waste caused by the formation of a cylinder wall oil film is avoided. In addition, the oil mist sprayed by the high-pressure oil pump generates vortex flow to the air in the cylinder due to the special-shaped surface of the piston body in the cylinder, and the oil mist is helpful for fully mixing the fuel and the air. Therefore, the utility model discloses well oil spout spark plug's design can improve the air-fuel ratio of engine.

When diesel oil is used as fuel, because the ignition point of diesel oil is low, when the air compression ratio in the cylinder is designed to be more than 20, the temperature is raised after compression because the temperature of sucked air is low when starting, and the oil mist in the cylinder can be directly ignited by high-temperature air, so that the ignition of a spark plug is not needed. Therefore, when diesel oil is used as fuel, the compression ratio of the cylinder is designed to be larger, and the oil injection spark plug is only designed to be an oil injection nozzle and does not need a spark plug. The utility model discloses can make high-power engine. After the engine is manufactured, each cross cylinder can be independently disassembled and assembled, the whole engine cannot be scrapped due to the fault of one cross cylinder, and the maintenance cost is reduced. Additionally, the utility model discloses can change the power size of engine according to the needs of power size and the number of random combination use cylinder.

The design can obviously reduce the transmission of the vibration generated by the impact of the reaction force on the cylinder body when a cylinder of the existing common in-line or V-shaped cylinder engine corresponds to a piston to work, can convert the kinetic energy wasted by generating the vibration into useful work, and can distribute the impact on a crankshaft to more directions, thereby greatly prolonging the service life of the equipment; the cylinder of the traditional crankshaft engine does work once, the flywheel rotates for two circles, the cylinder in the design removes the crankshaft piston and directly does work on the track flywheel, and based on the design of the piston roller track in the track flywheel, the cylinder does work once, the flywheel only rotates for half a circle, the rotating speed is only one fourth of that of the traditional crankshaft engine, and therefore the work load of related transmission parts can be greatly reduced.

The utility model provides a piston gyro wheel track is multistage arc curve track, and the gas expansion curve design when its design will be according to gas combustion makes the reciprocating motion of piston convert the rotary motion of flywheel.
