Description
Technical field
The present invention relates to a kind of air cylinder structure, internal-combustion engine and compressor.
Background technique
At present, various internal-combustion engines, compressor etc. all can use air cylinder structure as power plant.According to air cylinder structure inner cylinders arrangement mode, air cylinder structure can be divided into cylinder in line structure, cylinder in V-arrangement structure, W type air cylinder structure.Wherein:
Single-row cylinder arrangement structure is also referred to as cylinder air cylinder structure arranged side by side, and all cylinders are all connected on the same total bent axle that includes multiple crank throws.Single-row cylinder arrangement structure, available L representative, after add that cylinder number is exactly air cylinder structure code name, on Hyundai Motor, mainly contain L3, L4, L5, L6 type air cylinder structure.Advantage: cost is low, simple in structure, running balance is good, and volume is little, and stability is high, and low-speed torque characteristic is good, and fuel consumption is few, and compact dimensions is applied more extensive.Shortcoming: in the time of air displacement and cylinder number increase, the length of air cylinder structure will increase greatly, and volume increases, and has increased vehicle or other mechanical volumes.
Cylinder in V-arrangement structure is divided into two groups by all cylinders exactly, and adjacent cylinder is arranged with certain angle, makes two groups of cylinders from axially seeing and be in the shape of the letter V.All cylinders are all connected on line shaft by a bent axle that is provided with multiple crank throws.Height, the length of cylinder in V-arrangement structure are all less, on automobile, arrange more for convenience.Be convenient to improve discharge capacity and power and be suitable for the air cylinder structure compared with multi cylinder by expanding cylinder bore.In at present domestic medium-to-high grade vehicle, much adopt V-type 6 cylinder air cylinder structures.Especially Hyundai Motor is relatively paid attention to aerodynamics, requires the windward side of automobile the smaller the better, namely requires air cylinder structure cabin lid more low better.As its name suggests, V represents that air cylinder structure cylinder becomes V-type to arrange, and is generally 90 degree, and the vibrations can offset like this running time are more stable.Also there are 75 degree and 72 to spend.The wide-angle V10 engine that exceedes 90 degree has even been used in part racing car.Digitized representation below be the number of cylinder.Common cylinder in V-arrangement structure has V6, V8, V10, V12, also has V3, V5 and V16.Advantage: running is stable especially for V6, V8, V12, saving space.Shortcoming: complicated structure, be unfavorable for M R, and cost is higher.Meanwhile, the cylinders such as V3, V5 are the cylinder in V-arrangement structure of odd number all due to its structure or discharge capacity, not highly stable, especially as the V103L engine of F1 air cylinder structure, need especially to drop into a large amount of energy and funds for ensureing its stability.
W type air cylinder structure is that approximate W shape is arranged, and strictly also should belong to cylinder in V-arrangement structure in fact, is at least a mutation of cylinder in V-arrangement structure.W type air cylinder structure, all carries out the both sides cylinder of cylinder in V-arrangement structure low-angle staggering again, forms W type.All cylinders are all connected on line shaft by a bent axle that is provided with multiple crank throws.W type air cylinder structure is under the jurisdiction of the mutation of cylinder in V-arrangement structure.W type can do shortlyer by air cylinder structure compared with cylinder in V-arrangement structure, and bent axle also can be shorter, so just can save the shared space of air cylinder structure, and weight also can reduce simultaneously.But the width of this structure is large, make the inner space overfill such as the applied internal-combustion engine of air cylinder structure, compressor, complex structure; Running balance is poor.
Summary of the invention
