Background

An engine is a machine capable of converting other forms of energy into mechanical energy, including, for example, internal combustion engines (reciprocating piston engines), external combustion engines (stirling engines, steam engines, etc.), jet engines, electric motors, and the like. Such as internal combustion engines, typically convert chemical energy into mechanical energy. The engine is suitable for a power generation device, and can also refer to the whole machine (such as a gasoline engine and an aircraft engine) comprising the power device. Engines were first introduced in the united kingdom, and the engine concept is also derived from english, which is meant in its meaning as "power generating machinery".

The fuel supply is one of important links in the working process of the engine, the speed and the capacity of single fuel supply and the regularity and rhythm of the fuel supply have profound influence on the operation of the engine, and finding the fuel supply condition which can be matched with the rotating speed of a piston of the engine or the actual power demand can directly improve the working efficiency of the engine and the conversion rate of the fuel, prolong the service life of the engine and reduce the use cost of the total fuel.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a mechanical structure for freely adjusting the fuel supply rhythm of an internal combustion engine comprises a housing 1, a flywheel 2 is rotatably connected in the lower end of the housing 1, and the rotation radius and the rotation speed of the flywheel 2, an adjusting wheel 9 and the rotation main shaft of a cam are the same. The flywheel 2, the regulating wheel 9 and the cam are independently regulated in feeding rate and rhythm by the projections 12 and the like on the premise of keeping the same rotating speed.

The upper end swivelling joint of flywheel 2 has bent axle 3, the upper end swivelling joint of bent axle 3 has piston 4, feedstock channel 5 has been seted up to the upper end of shell 1, spring chamber 6 has been seted up to feedstock channel 5's side, the intracavity fixedly connected with spring beam 7 in spring chamber 6, the outer end swivelling joint of spring beam 7 has the pulley, its diameter slightly is less than the distance on 12 concave surface middle parts of lug to regulating wheel 9 surfaces, is greater than the distance on concave surface side to the surface of regulating wheel 9 simultaneously. When the spring rod 7 contacts the projection 12, the pulley will pass the upper surface of the projection 12 and press the spring rod 7, pushing the feed valve 8 inwards.

The inboard fixedly connected with feed valve 8 of spring lever 7, the outer end swing joint of spring lever 7 has regulating wheel 9, and the outer lane fixedly connected with dead lever 10 of regulating wheel 9, the outside swivelling joint of dead lever 10 has regulating spindle 11, and the outer lane fixedly connected with lug 12 of regulating spindle 11, lug 12 upper end set up to the convex surface, and the lower extreme sets up to the concave surface, and uses dead lever 10 to be the non-normal state for referring to. When the spring rod 7 just contacts the lug 12, the surface of the contact lug 12 is a surface with a shorter side end distance from the adjusting wheel 9, so that the pulley is prevented from passing through the lower end of the lug 12.

The inner ring of the adjusting shaft 11 is fixedly connected with a spring shaft 13, the inner ring of the spring shaft 13 is fixedly connected with a bevel gear set I14, a vertical gear of the bevel gear set I14 is fixedly connected with a rotating rod 15, the inner end of the rotating rod 15 is fixedly connected with a bevel gear set II 16, a horizontal gear of the bevel gear set II 16 is fixedly connected with a rotating handle 17, and the upper end of the shell 1 is fixedly connected with a discharging structure 18. The discharging structure 18 mainly comprises a discharging channel, a spring cavity 6, a spring rod 7, a discharging valve, a cam and a pulley. The main structure of the discharging structure 18 is similar to that of the feeding structure, the principle is the same, and meanwhile, the cam drives the spring rod 7 of the discharging structure 18 to stretch and retract, and the material distributing and discharging actions are completed.

Eight fixing rods 10, eight adjusting shafts 11, eight bumps 12, eight spring shafts 13, eight rotating rods 15, eight bevel gear sets 14 and eight bevel gear sets 16 are uniformly distributed on the outer ring of the adjusting wheel 9 by taking the circle center of the adjusting wheel 9 as a reference. The design of a plurality of lugs 12 can further improve the adjusting range of the feeding rhythm on the basis of the distance of the original structure.

The working principle is as follows: the flywheel 2 rotates, and the piston 4 is driven by the crankshaft 3 to do up-and-down reciprocating motion continuously, so that the actions of compressing and releasing fuel in the engine are completed.

The regulating wheel 9 rotates and at the same time the lug 12 is rotated by the fixing rod 10. When the cam 12 contacts the spring rod 7, it will press the spring rod 7 inwards, compressing the spring, and at the same time the inlet valve 8 starts to open, and fuel enters from the inlet channel 5 into the chamber where the piston 4 is compressed. The regulating wheel 9 continues to rotate and the spring rod 7 slides off the other side of the cam 12, while due to the asymmetry of the original state of the cam 12 the side of the concave surface of the cam 12 facing away from the surface of the regulating wheel 9 is pressed closer to the surface, while the spring inside the spring shaft 13 is compressed and the feed valve 8 starts to close. When the pulley leaves the cam 12, the feed valve 8 is completely closed, the feed stops, and the pulley no longer presses the cam 12, and the cam 12 returns to its original state due to the action of the spring shaft 13. This completes a complete feed process.

The rotating handle 17 is manually rotated to drive the projection 12 to rotate sequentially through the bevel gear set II 16, the rotating rod 15, the bevel gear set I14 and the spring shaft 13, when the convex surface and the concave surface of the projection 12 rotate to the original opposite positions, and when the spring rod 7 moves to the position of the projection 12, the projection 12 does not cause the compression of the spring rod 7 any more, and the feeding valve 8 is not opened any more. If the same regulating lugs 12 are spaced in sequence, the opening rate of the feeding valve 8 is reduced, but the rhythm is regular, and if the regulating lugs 12 are spaced in different ways, the opening rhythm of the feeding valve 8 is irregular. The state of the bump 12 can be freely adjusted according to actual requirements, so that the effect of adjusting the feeding rhythm of the fuel is achieved. Fig. 4 is a schematic representation of an irregular feed rhythm.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
