Description

Two cylinder fitting-types, four stroke synchronous internal combustion engine

Technical field:

Then the present invention relates to one kind again to convert thermal energy by making fuel and air generate thermal energy in gas in-cylinder combustion For the internal-combustion engine arrangement of machine power.

Background technique:

Existing internal-combustion engine arrangement, including reciprocating piston internal combustion engine, triangle rotor type internal combustion engine, gas turbine.Wherein, The shortcomings that reciprocating piston internal combustion engine is that the reciprocating motion loss of energy of piston is big, and energy transformation ratio is not high.In triangle rotor type The shortcomings that combustion engine is that compression ratio is low, is burnt insufficient.The shortcomings that gas turbine is that structure is complicated, and cost is high.

Summary of the invention:

The purpose of the present invention is to provide for one kind compared with prior art, and the simple low cost of structure, compression ratio is big, piston Need not move back and forth but rotary motion, the internal-combustion engine arrangement that can be run simultaneously with two cylinders with four strokes.To realize The purpose of the present invention, the present invention are cooperated using two circular cylinders, rotatable piston are respectively provided in two cylinders and can With the locular wall plate moved up and down, entire engine only has a main shaft, and shaft passes through two cylinders, and is connected by bearing It connects.Two pistons are mounted in shaft with flat key respectively.Cylinder is all divided into two parts by locular wall plate and piston in each cylinder, Two-part region and volume change with the rotary motion of piston, wherein first cylinder with the apparent position of piston and It is divided into suction zone and compressional zone, second cylinder is divided into work done area and exhaust area with the apparent position of piston, in each cylinder Locular wall plate and the contact surface of piston be all scarf, in favor of the mutual movement of room wooden partition and piston, locular wall plate is mounted on room It can move up and down in siding seat.Gas conditioner is equipped with outside two cylinders, be equipped with inside gas conditioner spherical air storage chamber, Garden cylindricality breather chamber, taper breather chamber and valve.The piston of two cylinders synchronous rotary in same shaft when work, First cylinder carries out air-breathing and compression stroke simultaneously, and compressed air is first stored in the spherical gas storage of gas conditioner It is indoor.When second cylinder is in workspace, by compressed air sequentially input gas conditioner garden cylindricality vent chamber and In the work done area of taper vent chamber and second cylinder, fuel burning is then sprayed into, the high pressure gas for generation of burning pushes away Piston rotation in dynamic second cylinder, piston drive shaft to rotate again, make second cylinder while carrying out work done and exhaust punching Journey makes first cylinder while carrying out air-breathing and compression stroke.In whole work process, air-breathing, compression, work done, exhaust four Stroke is synchronous to carry out.Two cylinders and two-piston shape are identical, but the model of first cylinder and piston is greater than second cylinder And the model of piston, the ratio between two cylinders and two-piston geomery are 1.3 times or more, to realize that compression ratio meets technology need It wants.The valve of gas conditioner is mounted in conduit by push rod and rocker arm timing open and close, push rod, and conduit is mounted on second gas On cylinder outer wall, push rod is in contact with ram seat, and ram seat is in contact with valve cam, and cam, which is equipped with axis hole and is mounted on flat key, to be turned On axis.The bearing of two cylinders cannot be axially moved in shaft, and this technology is disclosed now.Two pistons have number The shape of " 6 ".On two pistons, be designed with piston ring, piston seal plate, sliding triangular-shaped wedge, with anti-gas-leak.Two The angle of piston and valve cam in shaft be it is different, mutual angle is fixed between them, so that internal combustion engine Device air-breathing, compression, work done, exhaust stroke reach high efficiency.In second cylinder inner wall work done area, close to locular wall panel seat Position is equipped with atomizer and spark plug.For the need of work of the internal combustion engine of adaptation different capacity, the design point of gas conditioner For high-power type and small-power type, in small-power type gas conditioner, garden cylindricality breather chamber and taper breather chamber are conjunctions two For a Room, internal-combustion engine arrangement of the invention is additionally provided with fuel oil supply system, air supply system, governor, accumulated energy flywheel, profit Sliding system, cooling system, ignition system, these technologies are disclosed now.

In work, piston in two cylinders rotates, the air-breathing of first cylinder simultaneously under the drive of same root shaft Area is from external inspiration air, and compressional zone then synchronizes and carries out compressed air.Compressed air, is first stored in gas conditioner In interior spherical air storage chamber, when second cylinder is in work done area, the valve in gas conditioner in cam and push rod and is shaken Arm effect is lower to open, and compressed air enters the garden cylindricality vent chamber of gas conditioner, and after valve return, compressed air enters garden In taper vent chamber and second cylinder work done area, fuel oil is then sprayed into, then spark plug sparking makes fuel burning, after burning The high pressure gas of generation pushes the piston rotation of second cylinder, and piston drives shaft rotation again, make second cylinder work done with Exsufflation synchronization carries out, and makes first cylinder is synchronous to carry out air-breathing and compression stroke.In this way, internal-combustion engine arrangement air-breathing, compression, work Function, exhaust stroke are carried out with regard to synchronous.

The present invention compared with existing internal-combustion engine arrangement technology, due to using two circular cylinders and its inside piston and Gas conditioner and work, piston is rotary motion, thus compared with existing internal-combustion engine arrangement, and there is structure simply to make Valence is low, and compression ratio is big, the high advantage of energy transformation ratio.
