Abstract

The utility model discloses a multi-piston internal combustion engine with a common combustion chamber. The multi-piston internal combustion engine comprises a hollow oil sump provided with a flywheel and a plurality of air cylinders provided with pistons inside, wherein one ends of the cylinders are communicated with the inside of the oil sump, and the other ends of the cylinders are mutually communicated to form a same common combustion chamber. The internal combustion engine has a simple structure and high fuel utilization rate, thereby greatly saving the fuel.

Description

Multi-piston type internal-combustion engine with common firing chamber

Technical field

The utility model relates to internal-combustion engine, especially relates to the multi-piston type internal-combustion engine with common firing chamber.

Background technique

After internal-combustion engine appears at second industrial revolution, be used for the engine of the traffic tool such as automobile or other instruments, internal-combustion piston engine utilizes gasoline vapour or diesel oil bavin fuel to produce pressure more.All in cylinder, fuel-air mixture is injected in it piston, is lighted then.Hot gas expands, and promotes piston and moves backward.This straight line motion of piston converts circular movement to by connecting rod and bent axle.Generation is that Conversion of energy is other energy or speed, satisfies people's demand.Current social energy shortage, people want to improve the utilization ratio of fuel, but the internal-combustion engine that uses on the present market is low to the utilization ratio of fuel, has caused the waste greatly of fuel.

The model utility content

The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of multi-piston type internal-combustion engine with common firing chamber is provided, and this Structure of Internal-Combustion Engine is simple, to the utilization ratio height of fuel, has saved fuel greatly.

The purpose of this utility model is achieved through the following technical solutions: the multi-piston type internal-combustion engine with common firing chamber, oil sump, the inside that comprises inner hollow and be provided with flywheel is provided with some cylinders of piston, described cylinder one end and oil sump internal communication, the other end are interconnected and constitute same firing chamber.

The connecting rod of described piston by correspondence connects with corresponding flywheel in being arranged on oil sump.

Described firing chamber is provided with suction port and relief opening and the igniter that communicates with its inside.

Described flywheel is provided with the moving runner concentric with flywheel, is connected with rotating shaft on the described moving runner.

Described moving runner is connected with rotating shaft by belt.

In sum, the beneficial effects of the utility model are: this Structure of Internal-Combustion Engine is simple, to the utilization ratio height of fuel, has saved fuel greatly.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited only to this.

Embodiment:

As Fig. 1, Fig. 2, Fig. 3, the multi-piston type internal-combustion engine with common firing chamber shown in Figure 4, oil sump 1, the inside that comprises inner hollow and be provided with flywheel 2 is provided with some cylinders 12 of piston 7, described cylinder 12 1 ends and oil sump 1 internal communication, the other end are interconnected and constitute same firing chamber 8.

The connecting rod 6 of described piston 7 by correspondence connects with corresponding flywheel 2 in being arranged on oil sump 1.

Described firing chamber 8 is provided with suction port 9 and relief opening 11 and the igniter 10 that communicates with its inside.

Described flywheel 2 is provided with the moving runner 5 concentric with flywheel 2, is connected with rotating shaft 4 on the described moving runner 5.

Described moving runner 5 is connected with rotating shaft 4 by belt 3.

Four-stroke working principle: rotating shaft 4 is rotated, driving moving runner 5 by belt 3 rotates, moving runner 5 drives flywheel 2 and rotates, and flywheel 2 drives connecting rod 6 motions, and connecting rod 6 motions drive piston 7 and move reciprocatingly along cylinder 12 walls in cylinder 12; Fig. 1 is that piston 7 is in the range stage, under the effect of inertia of flywheel 2, piston 7 moves along cylinder 12 walls, firing chamber 8 internal pressure deficiencies, suction port 9 is opened, and relief opening 11 is closed, the mixture that sucks air and fuel enters firing chamber 8, the piston 7 that arrives Fig. 3 is compressed to the range place, and suction port 9 is closed, and the piston 7 in the both sides cylinder 12 compresses simultaneously, driving flywheel 2 rotates, arrive the range place of piston 7 shown in Figure 1, the mixture in the firing chamber 8 is lighted by igniter 10 owing to the temperature height, the energy that burning produces oppositely promotes piston 7, drive flywheel 2 and rotate, as shown in Figure 2, after arrival is shown in Figure 3, relief opening 11 is opened, then waste gas after burning is discharged firing chamber 8 by relief opening 11, the drive lower piston 7 at flywheel 2 inertia enters the position of Fig. 4 to Fig. 1 simultaneously, begins next cyclic process.

Adopt common firing chamber 8, can improve the combustion efficiency of fuel, improve the utilization ratio of fuel, saved fuel.

Take aforesaid way, just can realize the utility model preferably.
