The present invention has different working principles and structure with the two-stroke strokes oscillating piston internal combustion engine on prior art, and the present invention is a four stroke engine, and the former is a two stroke engine.U. S. Patent is similarly two-stroke internal combustion engine.

The present invention and strokes oscillating piston internal combustion engine---four cylinder engine has diverse structural type, and oscillating-piston of the present invention and cylinder body constitute two working cylinders, and oscillating-piston of four cylinder engine and cylinder body constitute four working cylinders.

The present invention is development on the basis of 1974 and secondary in 1996 success pratice in real machine, is another successful type.

The single or multiple oscillating-piston series connection of summary of the invention is two cylinder or multicylinder four-stroke explosive motor, can adopt single oscillating-piston and cylinder body to constitute two cylinder, also can adopt a plurality of oscillating-pistons and cylinder body to constitute multi-cylinder (the cylinder number is the diploidy number of oscillating-piston number), drive by same bent axle [1], crank [13], side rod [2], each crank, connecting rod drive an oscillating-piston [3], constitute two working cylinders.

The present invention can realize the middle low power four stroke engine, also can realize the superpower four stroke engine.The present invention adopts four stroke engine, and Economy can be first of the various motors, meets contemporary requirements of saving energy.Because this kind engine mechanical efficiency is higher than other motors, quartastroke engine work cycle, internal efficiency are again the highest in each motor, thereby effective efficiency can be first of the various motors.

Adopt four oscillating-piston eight cylinder four-stroke motors for large-scale or super-huge motor suggestion, this kind engine structure is simple, and peak output can reach more than 100,000 horsepowers, meets the requirement of large-scale power station, boats and ships, 30 ton oil tankers and luxury passenger steamer.Mid power can be suitable for the requirement of power station, locomotive, medium and small-scale vessel.

Adopt this kind motor, stable working, noise is little, and output torque is even, and starting performance is good, and outer molded capacity can be 1/5th to 1/10th of available engine, and manufacture cost is the closely reduction of several times also.

Four oscillating-pistons, eight cylinder four-stroke motors, as shown in Figure 2, mark four oscillating-pistons with [Q], [R], [S], [T], head and the tail two oscillating-pistons [Q], [T] swing synchronously, middle two oscillating-pistons [R], [S] swing synchronously, when [Q], [T] clockwise swing synchronously, [R], [S] be counter-clockwise swing synchronously, bent axle revolution half way around, swaying direction of piston change.Adopt the inertial force and the inertia couple of above motion mode entire mechanism can accomplish complete equilibrium.

As shown in Figure 2: [Q] oscillating-piston and cylinder body form [A], [B] two working cylinders, [R] oscillating-piston and cylinder body form [C], [D] two working cylinders, [S] oscillating-piston and cylinder body form [E], [F] two working cylinders, and [T] oscillating-piston and cylinder body form [G], [H] two working cylinders.[A] cylinder air inlet when oscillating-piston [Q] clockwise direction is put, the exhaust of [B] cylinder.[C] cylinder exhaust when oscillating-piston [R] is counterclockwise swung, the air inlet of [D] cylinder.When oscillating-piston [S] is counterclockwise swung, [E] cylinder air compression, [F] cylinder combustion gas expansion working, when oscillating-piston [T] clockwise direction is swung, [G] cylinder combustion gas expansion working, [H] cylinder air compression.

Therefore: the compression work at this working stroke [E] cylinder is directly paid by the expansion work of [F] cylinder by oscillating-piston [S], does not need to transmit by connecting rod, bent axle.The compression work of [H] cylinder is directly paid by the expansion work of [G] cylinder by oscillating-piston [T] equally, does not need to transmit by connecting rod, bent axle.Significantly reduce the power loss of intermediary agency like this, improved mechanical efficiency greatly.

Turn over a week at bent axle, during the 3rd stroke, oscillating-piston [Q] clockwise direction swing once more, cylinder [B] air compression, cylinder [A] combustion gas is expanded, and cylinder [B] compression work is directly transmitted by oscillating-piston [Q] by cylinder [A] expansion work.Same oscillating-piston [R] is done swing counterclockwise once more, cylinder [C] air compression, and cylinder [D] combustion gas is expanded, and cylinder [C] compression work is directly directly transmitted by oscillating-piston [R] by cylinder [D] expansion work.So also significantly reduce the power loss of intermediary agency, improved mechanical efficiency greatly.

Oscillating-piston plays the effect that is similar to the flywheel storage device again, come the maximum force of balanced gas with maximum inertia force, again energy is progressively discharged subsequently, the stressed of piston and connecting rod bearing, crankshaft crank bearing reduced greatly, can reduce by 2.5 times approximately, reduce mechanical wear, improved working efficiency.

Oscillating-piston [3] is used sliding supported condition, because the support of Sealing, piston is suspended among the cylinder body, does not directly contact with cylinder body and rubs, and greatly reduces mechanical friction loss, has improved mechanical efficiency.Do not resemble not only piston directly friction in cylinder of Reciprocating engine, and piston bounces laterally in cylinder, produces horizontal slapping noise.

The present invention adopts cylinder body, cylinder cap, support, each crankshaft crank drives an oscillating-piston and two working cylinders of cylinder body formation through connecting rod, simplifies the structure greatly, and whole layout is the compactness of ten minutes again, thereby can accomplish little external dimension, low-cost and send big power.

The patent of invention that the present invention can adopt the inventor to declare on May 15th, 2006: swing piston compressor end surface sealing device, number of patent application: 200610082248.2, as end face seal of the present invention, can guarantee the sealing that motor is good.

The present invention to little, in, big all kinds of motors all can be suitable for, mini engine can adopt petrol engine, diesel engine, natural gas engine, can adopt diesel engine and heavy oil engine for big-block engine.

Description of drawings is seen Fig. 1, Fig. 2
