CN-121976878-A - Four-stroke combined piston double acting internal combustion engine

Abstract

The invention discloses a new technical scheme of a new internal combustion engine, wherein a cylinder body of a cylinder is prolonged to a length exceeding two cylinders, two ends are cylinder covers, a gear hole is formed in the middle of the cylinder, two symmetrically connected pistons are arranged in the cylinder, a connecting body is provided with a strip concave gear, four strokes do work twice, the working sequence is that a first cylinder 2 piston does work 3 piston exhaust, a 2 piston exhaust 3 piston intake, a 2 piston intake 3 piston compression, a 2 piston compression 3 piston do work, 20, 21 and 24 and 25 gears drive when the 2 piston does work, 20, 21 and 22 and 23 gears drive when the 3 piston does work, and a second cylinder 4 piston intake 5 piston compression, a 4 piston compression 5 piston do work, a 4 piston doing work 5 piston exhaust and a 4 piston exhaust 5 piston intake. Therefore, the power of the traditional four-cylinder engine can be even exceeded as long as two cylinders are combined, and the purposes of reducing the volume of the engine, reducing the weight of the engine, improving the stability of the piston and improving the thermal efficiency are achieved.

Claims (7)

1. 1. The engine core part consists of an lengthened cylinder, a combined piston, a convex gear strip and a concave gear. The piston is connected with the concave gear through a convex gear strip. The combined piston reciprocates in the cylinder, and the other cylinder compresses, does work, exhausts air, and does work twice in four strokes of air intake and air compression, doing work, exhausting air, and pushes the concave gear to rotate through the convex gear bar.
2. 2. The novel engine is characterized in that the four-stroke power is applied twice.
3. 3. The novel engine is characterized in that two pistons are combined into a whole and provided with a convex gear strip.
4. 4. The new engine features that different top dead centers are used for acting and exhausting.
5. 5. The novel engine is characterized by being driven by an intermediate concave gear.
6. 6. The novel engine is characterized in that a high-pressure air inlet valve is added.
7. 7. The novel engine is characterized in that the cylinder body is prolonged to the length of two cylinders.
