Abstract
The present invention relates to an internal-combustion engine, particularly small diesel engine.The flywheel set structure of being made up of flywheel and flywheel casing is housed on this internal-combustion engine.Make the blade of calming the anger on the flywheel; Make on the flywheel casing spiral case, diffuser arrangement and suction port are arranged.Have one to carry compressed-air actuated pipeline that flywheel and cylinder of internal-combustion engine chamber are linked together.Like this, the flywheel set structure possesses the function of promising supercharging of internal combustion engine again except the function that can possess storage and delivered energy.
Description
A kind of flywheel block device that pressurized effect can be arranged is applicable to internal-combustion engine, is specially adapted to small diesel engine.
The present invention relates to an internal-combustion engine, particularly small diesel engine.On internal-combustion engine, have a flywheel block device, improve this flywheel block device, it is not being lost outside the original function, possess the function that has pair internal-combustion engine to carry out supercharging again.
Adopting supercharging device is the effective way that improves power of IC engine.Present boosting method has: engine driven supercharging, exhaust gas turbocharge, inertia supercharging etc.But because the small diesel engine volume is little, reason such as air displacement is little is so existing mechanical supercharging device and exhaust gas turbocharge device all are difficult to and its coupling.There is the small diesel engine overwhelming majority of supercharging all to adopt inertia supercharging at present.The inertia supercharging method has many good qualities, but also exists the some shortcomings part, as:
1. need a very long suction tude, like this, strengthened the volume of small diesel engine.
2. adopt the diesel engine of inertia supercharging device, when using air-strainer, will influence its pressurized effect widely.
So task of the present invention is created a kind of flywheel block device being said this internal-combustion engine, particularly small diesel engine.This flywheel block device not only can keep the function of original storage and dispensing kinetic energy, and itself is again a mechanical pressurizing apparatus, thereby internal-combustion engine is carried out supercharging.
The solution of invention is:
Making on flywheel has thicker spoke and wheel rim, makes it to have the function of storing and discharging kinetic energy, and make the blade of calming the anger on flywheel.
On flywheel casing, make suction port, diffuser arrangement, spiral case and relief opening are arranged.
Flywheel is installed on the bent axle, and bent axle has driven the flywheel rotation, and air enters the runner that the blade of calming the anger on the flywheel is formed by being manufactured on the suction port on the flywheel casing, and the blade of rotation drives the ambient air motion, and the pressure of air and airspeed are increased.The air of high-speed motion is through diffuser arrangement, and the kinetic energy of it quite a few is converted into the pressure energy, and like this, the speed of air reduces, and pressure raises.Then, these air are collected by spiral case, enter cylinder chamber through relief opening by carrying compressed-air actuated pipeline.This carries compressed-air actuated pipeline not only to be connected with flywheel casing but also to be connected with the cylinder of internal-combustion engine chamber, and the joint requires sealing, resistance to compression, is as the criterion with air tight.
By the improvement of above scheme, make original flywheel block device when not losing its original function, possessed function of increasing pressure again.Mechanical pressurizing apparatus described in the present invention is compared with the mechanical pressurizing apparatus in the prior art, though be corresponding on principle.But, because the present invention has provided so a solution.Therefore, possess again following two advantages arranged:
1. simplified the drive mechanism of mechanical pressurizing apparatus;
2. reduce driving device supercharging device and the spent part bent axle merit of its driving mechanism, therefore reduced the fuel consume of internal-combustion engine.
Solution of the present invention has solved mechanical pressurizing apparatus in the prior art and has been difficult to the difficult problem that is complementary with compact internal combustion engine.In addition.The technical order of the mechanical pressurizing apparatus in other technical order that this mechanical pressurizing apparatus described in the present invention had (as the power improvement value etc.) and the prior art is corresponding to.
Compare with the inertia supercharging device that diesel engine adopted in the prior art, the present invention possesses following three advantages is arranged:
1. reduced the volume of diesel engine;
2. pressurized effect is better than inertia supercharging, and is not subjected to the influence of use occasion;
3. adopt the internal-combustion engine of this flywheel block device of the present invention can use air-strainer.
On the 190 homemade diesel engines, so a kind of flywheel block device is arranged, and the flywheel inwall has also been made the blade of calming the anger on this device, still, not making on its flywheel casing has spiral case, and the air that the blade of calming the anger drove on the flywheel is air inducing cooling water tank and dissipating merely just.Therefore, this prior art is compared with solution of the present invention, all is not corresponding on function still from structure.
A kind of embodiment of invention is described on the accompanying drawing:
Fig. 1 is the flywheel set plan view.Fig. 2 is the flywheel set left view.Fig. 3 is a schematic representation of carrying compressed-air actuated pipeline to be connected with cylinder of internal-combustion engine chamber and flywheel block device.
Below we describe this embodiment's concrete structure and working condition in conjunction with the accompanying drawings in detail:
Flywheel (1) manufacturing has thicker spoke and wheel rim, and the physical dimension of spoke and wheel rim belongs to prior art, and we do not narrate here.Thicker spoke and wheel rim are in order flywheel to be possessed store and the function of dispensing kinetic energy, and the function of the flywheel in this function and the prior art is consistent.
The flywheel inwall manufacturing blade (8) of calming the anger.
Flywheel casing (2) is gone up to make suction port (3), relief opening (5), water conservancy diversion diffusion blade (9) and spiral case (10).
Flywheel (1) is installed in an end of bent axle (4), and flywheel casing (2) is installed on the internal combustion (IC) engine airframe (11), and flywheel (1) is formed flywheel block device with flywheel casing (2).
Carry compressed-air actuated pipeline (7) that the relief opening of flywheel block device (5) is connected with cylinder of internal-combustion engine chamber (12).Flange plate in an end flange dish of carrying compressed-air actuated pipeline (7) and the flywheel block device on the relief opening (5) is connected.The flange plate of the other end is connected with cylinder of internal-combustion engine chamber (12).The cotton rubber sheet gasket of two joint junction plane pinners.Air tight to guarantee sealing.
In the present embodiment, mechanical pressurizing apparatus is a centrifugal-flow compressor, and the form of the blade of calming the anger (8) is a backward leaning vane.Spiral case (10) be shaped as variable cross section shape, it and flywheel casing (2) make one.Diffuser arrangement is made of the water conservancy diversion diffusion blade (9) that is manufactured on flywheel casing (2) inwall.
During work, bent axle (4) drives flywheel (1) rotation, makes suction port (3) locate to be negative pressure.Air enters the inner chamber of flywheel block device by suction port (3), and after entering the runner of blade (8) composition of calming the anger on the flywheel (1); Under centrifugal action, be compressed and be thrown toward the flywheel outer rim.Air has obtained energy from the flywheel (1) of rotation, and pressure and airspeed are increased.Behind water conservancy diversion diffusion blade (9), the kinetic energy of air changes the pressure energy again into, and the speed of air reduces, and pressure raises.The effect of spiral case (10) is to collect the air that flows out from water conservancy diversion diffusion blade (9).And by carrying compressed-air actuated pipeline (7) to transfer to cylinder of internal-combustion engine chamber (12).
