Detailed description of the preferred embodiments
The working principle of the gasoline rotor engine is as follows: as shown in fig. 5, the rotor 11 rotates clockwise (necessarily), and the slide bar 13 rotates along with the rotation, and simultaneouslyThe slide bar 13 makes radial telescopic movement along the inner wall of the cylinder body 10 in the slide bar groove 8 under the pressure action of the bow-shaped spring piece 12, and changes the volume of the air chamber, thereby completing four strokes of air suction, compression, power and exhaust. Each air chamber does work once when the rotor rotates one circle. Referring to fig. 6, 131, 132, 133 and 134 are slide bars, 5 is an intake port, 6 is an exhaust port, 14 is a spark plug, and a, b, c and d are 4 points different by 90 degrees. Taking the air chamber formed by the slide bars 131 and 134 as an example, when the slide bar 131 is located at the point a and the slide bar 134 is located at the point d, the volume of the air chamber is 0. After the slide bar 131 rotates past the point a, the volume of the air chamber gradually increases, the air mixture is gradually sucked into the air chamber from the air inlet 5, and when the air chamber reaches the point b, the volume of the air chamber reaches the maximum (the shaded part between the points a and b), and the air suction process is completed. After the slide bar 131 rotates through point b, the volume of the air chamber gradually decreases, the mixture is gradually compressed, and when the slide bar 131 reaches point c, the volume of the air chamber reaches the minimum (the shaded part between points b and c), and the compression process is completed. After the slide bar 131 passes through the spark plug 14, the spark plug 14 is ignited, the gas is combusted and expanded to produce work, and when the slide bar 131 reaches the point d, the volume of the air chamber reaches the maximum (the shaded part between the points c and d), thereby completing the work production process. After the slide 131 rotates past the point d, the volume of the air chamber gradually decreases, the exhaust gas starts to be discharged from the exhaust port 6, and the volume of the air chamber is zero when the slide 131 reaches the point a (the radius of the rotor and r in the cylinder)1Same), the exhaust process is completed.
The spark plug is controlled by an ignition control device, and a plurality of spark plugs may be provided.
The compression ratio of the engine is the ratio of the volume between points a and b (hatched portion) to the volume between points b and c (hatched portion) in fig. 6.
The volume between points c and d in fig. 6 (hatched portion) is larger than the volume between points a and b (hatched portion).
The working principle of the diesel rotor engine is as follows: as shown in figure 7, the rotor 11 rotates clockwise (necessarily), the slide bar 13 rotates along with the rotation, and simultaneously the slide bar 13 makes radial telescopic motion along the inner wall of the cylinder 10 in the slide bar groove 8 under the pressure of the bow spring leaf 12, so as to change the volume of the air chamber, thereby completing four strokes of air suction, compression, work and exhaust. Each air chamber does work once when the rotor rotates one circle. As shown in fig. 6, 131, 132,133. 134 is a slide bar, 5 is an air inlet, 6 is an air outlet, 16 is an oil nozzle, and a, b, c, d are 4 points which are different by 90 degrees. Taking the air chamber formed by the slide bars 131 and 134 as an example, when the slide bar 131 is located at the point a and the slide bar 134 is located at the point d, the volume of the air chamber is 0. After the slide bar 131 rotates past the point a, the volume of the air chamber gradually increases, air is gradually sucked into the air chamber from the air inlet 5, and when the air chamber reaches the point b, the volume of the air chamber reaches the maximum (the shaded part between the points a and b), and the air suction process is completed. After the slide bar 131 rotates by the point b, the volume of the air chamber gradually decreases, the air is gradually compressed, and the volume of the air chamber reaches the minimum (the shaded part between the points b and c) when the slide bar 131 reaches the point c, thereby completing the compression process. After the slide bar 131 rotates the oil nozzle 16, the oil nozzle injects oil, the diesel oil is compression-ignited to expand and do work, when the slide bar 131 reaches the point d, the volume of the air chamber reaches the maximum (the shaded part between the points c and d), and the work doing process is completed. After the slide 131 rotates past the point d, the volume of the air chamber gradually decreases, the exhaust gas starts to be discharged from the exhaust port 6, and the volume of the air chamber is zero when the slide 131 reaches the point a (the radius of the rotor and r in the cylinder)1Same), the exhaust process is completed.
The engine may be provided with a plurality of fuel injectors.
The compression ratio of the engine is the ratio of the volume between points a and b (hatched portion) to the volume between points b and c (hatched portion) in fig. 8.
The volume between points c and d in fig. 8 (hatched portion) is larger than the volume between points a and b (hatched portion).
The invention can be designed into four times of air chambers such as 4 air chambers, 8 air chambers and the like, and the more air chambers, the more the engine runs, the more stable the engine runs.
