The internal-combustion engine of a kind of internal combustion engine and this piston of use

The invention discloses the internal-combustion engine of a kind of internal combustion engine and this piston of use, it is applicable to the internal-combustion engine that the work done simultaneously of 2-4 piston is arranged in the cylinder body of single firing chamber.

Present reciprocating internal combustion engine, the piston of use, piston-top surface have plane, convex surface, concave surface, cavity, and this piston is applicable to a cylinder one piston type internal-combustion engine, is not suitable for the internal-combustion engine that 2-4 piston while work done arranged in the cylinder body of single firing chamber.

Absorb fuel combustion energy in order farthest to increase piston at cylinder body, save the energy, improve power of IC engine, the present invention has designed a kind of internal combustion engine and has used the internal-combustion engine of this piston.

The present invention is achieved in that the end face of piston is arranged to concave surface or cavity, at piston-top surface a groove is set, groove and concave surface or cavity UNICOM.

To use above piston IC engine cylinder body, be arranged to the internal combustion engine cylinders that single firing chamber has the work done simultaneously of 2-4 piston, cylinder cap will be set on cylinder body; Circular arc concave surface valve is set, spark plug or oil sprayer on cylinder cap; Spacing in the cylinder body between each piston top dead center is set to zero or equidistant, in cylinder body, install piston, on piston, install connecting rod, connecting rod links to each other with bent axle, bent axle in the same way an end model, the identical cylinder tooth of size are set, a line shaft is set, the driving cog that device 1 while is meshed with bent axle cylinder tooth on line shaft on cylinder between cog body, line shaft one end links to each other outputting power with gearbox on the body.Piston motion is to top dead center during work, and the cavity of piston head is combined into a firing chamber, and the groove combination of piston-top surface becomes an oilhole or breast door; Spark plug passes through breast door, the indoor compressed gas of ignition combustion, or oil sprayer sprays into fuel oil by the pure air of nozzle opening High Temperature High Pressure in the firing chamber.

Be described further below in conjunction with drawings and Examples

At piston head piston ring groove 15 is set, a cavity 3 is set on the end face of piston head, groove 2 is set, groove 2 and cavity 3 UNICOMs at piston-top surface.

Embodiment 2: a kind of internal combustion engine of Fig. 3

The end face of piston head is provided with a groove 2, groove 2 and concave surface 3 UNICOMs.

Embodiment 3: Fig. 4, Fig. 5, a kind of internal combustion engine of Fig. 6

Piston head is 90 ° or 120 ° of isoceles triangle shapes, and piston head is provided with a

groove

2,2 and links with concave surface (cavity) 3.

Embodiment 4: the internal-combustion engine of a kind of embodiment's of

use

1,2 pistons of Fig. 7, Fig. 8 is arranged to tubular 5 with internal combustion engine cylinders, and cylinder cap 13 is set on cylinder body; Circular arc concave surface valve 14 is set, oil sprayer (spark plug) 7 on 13; Put into two embodiments, 1,2 described pistons 1 at 5 two ends, two-piston in the cylinder body 1 is arranged to have same top dead center,

device connecting rod

8,8 links to each other with bent axle 9 on 1, at 9 one end device models, big or small identical cylinder driving cog 10,12; A transmission shaft 17 is set, the cylinder tooth that device while is meshed with 10,12 on 17, the 17 1 ends outputting power that links to each other with gearbox on the body on 10,12 bodies.

Power stroke, two-piston moves to top dead center, and piston head concave surface 3 is combined into a firing chamber 4, and groove combination becomes a hole 6, and combustion gas or pure air are compressed in 4; 7 by 6 combustion gas of lighting in 4, or high temperature, the pure air of high pressure spray into diesel oil in 4; Fuel combustion,

piston drive

8,8 to motion in the other direction rapidly and drive 9,9 and drive 10,12,10,12 and drive 11,11 simultaneously and drive 17,17 and by gearbox kinetic energy is exported.

The effect that the internal combustion engine top dead center is identical: one, the piston head cavity is combined into a firing chamber, two, at utmost reduce, during fuel combustion with the surface of contact of casing wall, the raising energy utilization rate.
