Description

The opposite-compacting type gas internal-combustion engine

Technical field:

The present invention relates to piston reciprocating internal combustion engine, especially a kind of opposite-compacting type gas internal-combustion engine that can effectively improve output power and increase moment of torsion.

Background technique: existing Dual-piston IC engine is in the work by combustion process, piston moves in cylinder and all adopts premature ignition, inflammable gas is not continued compression in the combustion process of lighting a fire, and two pistons all are to arrive the budc igniting, resistance is very big, in addition, work done mode by do negative work, the repetitive cycling of not doing work, do work.At this, do negative work, all there is not the problem of wasting fuel in working stroke, and cause delivery efficiency not high.

Summary of the invention:

Deficiency at above-mentioned prior art existence, the invention provides a kind of opposite-compacting type gas internal-combustion engine, it is by internal combustion engine, bent axle, cylinder are formed, and it is characterized in that: (1), at least two cylinders are a working cell, are called master cylinder and countercylinder, a reciprocating piston is housed in each cylinder, piston is connected with bent axle by connecting rod, and the crank throw of two pistons is unequal, and the crank throw R of main piston is less than the crank throw r of sub-piston; (2), the crank throw of the crank throw of main piston and sub-piston is or not same plane, differs an angle a each other, angle a greater than 0 degree less than 45 degree.(3), the firing chamber of two cylinders is positioned at cylinder head by being communicated with the air drain connection.

The overall compression ratio of described two cylinders is looked oil plant and is not all 9-20: 1; Master cylinder and countercylinder each other for be arranged in parallel, level is correct arranges or be the correct layout of A type.

Described master cylinder and countercylinder can adopt even number or odd number to form the working cell, and multi-cylinder mechanism adopts even number or odd-multiple.Master cylinder adopts different cylinder diameters with countercylinder.

The opposite-compacting type gas internal-combustion engine structure that the present invention proposes is a unit with two cylinders, and the main crankshaft radius has an igniting lead angle, and main piston has left top dead center during igniting, and work done is not had reaction force, and good antideflagration property is arranged, and has improved the pressure of firing chamber; Because the firing chamber of two cylinders is communicated with, total combustion chamber volume does not increase, even under the situation that also can reduce, obtains higher pressure and bigger moment of torsion.The present invention adopts existing manufacturing process production, does not increase manufacture cost, helps promoting the use.

View when Fig. 4 arrives top dead center for main piston.

View when Fig. 5 is igniting.

Fig. 7 is the schematic representation of the embodiment of the invention two.

Fig. 8 is the schematic representation of the embodiment of the invention three.

Fig. 9 is the schematic representation of the embodiment of the invention four.

Embodiment is further specified by following embodiment.

Embodiment one as shown in Figure 1, master cylinder and countercylinder are arranged in parallel and constitute a working cell, correspondence disposes main piston 1 and sub-piston 3, connection air drain 2 by two cylinder tops surrounds total firing chamber, major and minor piston is connected with bent axle 4 by connecting rod, the relative pressurized gas of to-and-fro motion in each comfortable cylinder.The sectional area of the connection air drain between the major and minor cylinder its wide and height are designed to (10-20): 1.The crank throw of main piston is R, and the crank throw of sub-piston is r, and R＜r.Crank throw equals crank arm length.

Internal combustion engine configurations parts such as the distribution device of major and minor cylinder, connecting rod are identical with prior art in the present embodiment.

Shown in Figure 2, two crank throws have phase difference angle a not at grade between R and the r, the super previous angle a of the crank throw R of main piston, and the value of angle a is less than 45 degree greater than 0 degree.

Among Fig. 3, two pistons pressurized gas that moves upward simultaneously.

Among Fig. 4 owing between two crank throws a phase bit angle is arranged, by the different length of crank throw and secondary crankshaft radius greater than the main crankshaft radius.Main piston arrives top dead center 5 earlier, and sub-piston still continues up pressurized gas, and the reciprocating cycle of two-piston is identical,

Fig. 5,6 are the premature ignition process, and spark plug sends inflammable gas in the electrical spark ignition combustion chamber, and in-cylinder pressure, temperature sharply rise, the acting of expanding.Main piston 1 has left top dead center and has moved downward during igniting, and sub-piston 3 continues up pressurized gas, because crank throw difference, when same rotational speed, the movement velocity of sub-piston continues pressurized gas greater than the speed of main piston in the ignition process, most combustion gas in the countercylinder at this moment are pressed onto master cylinder by being communicated with air drain 2, make total fuel chambers volume not increase, reduce on the contrary, thereby guarantee in the firing chamber enough pressure is arranged.Compare with existing internal-combustion engine, efficient height, power are big, fuel-economizing, toxic emission are low.

Because most combustible gases are in main fuel chamber, secondary fuel chambers combustible gas seldom, and is also relative very little to sub-piston and resistance, thereby the up top dead center of sub-piston is easy to.

Embodiment two is the horizontal opposite-compacting type gas internal-combustion engine working principle that proposes according to the present invention, as Fig. 7 and shown in Figure 9.

Embodiment three is the A type opposite-compacting type gas internal-combustion engine working principle that proposes according to the present invention, as shown in Figure 8, the structural feature of most of mechanism is identical with embodiment one, its unique texture is: major and minor piston is oppositely arranged in the cylinder of same level, need not use cylinder head, each have independently crankshaft ﹠ connecting, identical period of rotation is arranged, two bent axles are connected by gear.Inlet and outlet door distribution device and spark plug configuration 6 adopt prior art, are installed in respectively on the side, total firing chamber between the two-piston.Because adopt the subtend compression, identical crank throw can be accomplished high compression ratio.Very favourable to diesel engine, piston stroke is short, inertia is little, so can be designed to high speed engine.Use also can move to the firing chamber outside the air exchange system on diesel engine the time, reduces the requirement to inlet and outlet door distribution device, sees Fig. 9.

Horizontal is applicable to that high-rating generator, heavy engineering machinery, boats and ships, warship, lathe use; The A type structure that parallel type shown in the embodiment one and embodiment three provide is applicable to that automobile uses.

The above embodiment of the present invention also can adopt different cylinder diameters to pressing; Multi-cylinder adopts even number or odd-multiple all can.
