Embodiment

The present invention is described further below in conjunction with the accompanying drawings：

As shown in figure 1, the present invention, which provides a kind of air-cooled power-assisted two, rushes double plug opposed type supercharged diesel engines, including by gas Cylinder and the combustion chamber for the piston formation being arranged in cylinder, every group of piston of the engine do the relative work from motion for two Plug 1, the end face of each piston is recessed a conoid groove 2, and the piston rod 3 of piston is connected to the bent axle in crankcase 4 5, bent axle 5 is connected with bent axle bevel gear 6, and bent axle bevel gear 6 is engaged with the umbrella tooth on power transmission shaft 7, and transmission is provided with power transmission shaft 7 Umbrella tooth 8, transmission umbrella tooth 8 is engaged with the umbrella tooth of transmission vertical rod 9 upper end, umbrella tooth and the umbrella tooth on main shaft 10 of transmission vertical rod 9 lower end Engagement, the end of main shaft 10 is provided with active flywheel 11.Two grooves add the space of combustion chamber, increase compressed air Amount.

Cylinder sleeve 14 is cased with outside cylinder 13, is formed to be provided with air-cooled passage 15, cylinder between cylinder and cylinder sleeve and is passed through burning Air inlet 16, exhaust outlet 17 and the jet of chamber interior, air inlet 16, exhaust outlet 17 and jet pass through air-cooled passage 15, enter Gas port 16, exhaust outlet 17 and jet are sealed off between air-cooled passage 15；Exhaust outlet is connected to turbine 12 by air channel Turbine rotation is driven, turbine 12 is with being connected two supercharging air blower fans.One is air-cooled booster fan 18, and another increases for air inlet Pressure fan 19, turbine 12 links with air-cooled booster fan 18 and plenum blower fan 19, and air-cooled booster fan 18 is connected to air-cooled Passage 15, plenum blower fan 19 is connected to cylinder air inlet 16.

Wind turbine 20 is additionally provided with main shaft 10, turbine 12 is connected with the wind turbine 20 and drives the wind turbine 20 to revolve Turn, make the wind turbine 20 drive main shaft 10 to rotate.

Air inlet 16 and the asymmetric setting relative in the middle of cylinder of exhaust outlet 17, the position of exhaust outlet 17 is relative to air inlet 16, closer in the middle of cylinder, air throttle are provided with exhaust outlet 17, and the air throttle is to open and pass through by the expansive force of waste gas The structure that itself acting force of the spring is closed automatically.

Cylinder and piston are horizontally disposed, and the form of piston is one of the following two kinds, the first front bottom end in piston Gap 111 is provided with, as shown in fig. 7, being for second that the front end of piston is from top to bottom tilted to both sides so that conoid groove 2 Upper edge is longer than lower edge, as shown in Figure 6.When so causing piston movement, the power that the upper surface 21 of conoid groove 2 is received is more than conoid The table 22 below stress of groove 2 so that piston is balanced out the gravity of piston or the gravity of a part of piston by larger upward power, Reduce the frictional force of cylinder lower surface and piston, reduce eccentric wear.

The upper surface of conoid groove 2 is more than the lower surface and piston lower wall of conoid groove 2 with the angle of piston upper wall Angle.As shown in figure 5, the upper edge of conoid groove 2 is longer than lower edge.

In addition, setting lubricating oil pump under main shaft, lubricating oil pump is whole equipment fuel feeding by pipeline, in the exit of lubricating oil pump Two oil filter are parallel with, two oil filter pass through the diverse location fuel feeding that pipeline is equipment, two machine oil respectively The oil-out of cleaner is connected by communicating pipe, so when machine oil normally circulates by two pipelines be respectively all parts supply Oil, has fully ensured the effect of fuel feeding, and once one of oil filter is blocked, the machine oil of the side that is blocked will all from Another oil filter is fuel-displaced, then by the effect of communicating pipe 222 still can by the machine oil of filtering from it is new send back to by In the pipeline for blocking side, it is ensured that the normal operation of equipment, and conventional equipment is all a pipeline, an oil filter, So when oil filter does not work, machine oil will be directly entered whole equipment, so not only influence whether smoothing effect, also Whole equipment can be seriously damaged, therefore the setting of the two-shipper oil rectifier of the present invention just solves this problem well.

Operationally, active flywheel 11 is connected the present invention with starter motor, drives active flywheel 11 to start by starter motor whole Individual engine, gas does work in combustion chambers burn, the driving rotation acting of bent axle 5, drives main shaft to rotate by power transmission shaft 7, realizes The waste gas of combustion chamber is rotated by pipeline driving turbine 12 in diesel engine operation principle, the application, and turbine drives air-cooled increasing simultaneously Pressure fan 18 and plenum blower fan 19 work, and plenum blower fan 19 will throw air inlet into after the air pressurized of cylinder air inlet Mouthful, increase efficiency of combustion, improve engine power, on the other hand air-cooled booster fan 18 throws gas in air-cooled passage to hair into Motivation cylinder is cooled down.

Meanwhile, the driving wind turbine 20 of turbine 12, which rotates, makes it further increase the power of main shaft rotation.

Piston rod connection bent axle does the motion raised from lower to upper, during piston rod movement, does the action raised from lower to upper, also It is the clockwise direction in Fig. 6 shown in arrow, thus the machine oil of bottom is raised to top in motion, machine oil is effectively prevented Skewness.

The lubricating oil operation principle of lubricating oil and miscellaneous part not this Shen same as the prior art in cylinder in the application Protection scheme please, is repeated no more herein.

In addition, the conoid groove 2 in the piston of the application is asymmetrical structure, that is, air burning in combustion chamber When expansion is done manual work, expansive force is withstood on the inner surface of conoid groove 2, and because conoid groove 2 is asymmetrical structure, i.e., The power that upper surface 21 is received is more than the power that lower surface 22 is received, and the power that upper surface 21 is received can balance out a part of piston itself weight Power, thus prevents eccentric wear of the piston lower surface caused by discontinuity, because this pancake engine is horizontal cloth Put, so the bottom of piston can cause the phenomenon of eccentric wear in the presence of piston self gravitation, and the conoid groove 2 of the present invention The neutralization of power is realized, this problem is solved.

It is characteristic of the invention that a cylinder two is filled in, one times of air inflow, one times of working stroke and one times of acting are added Lifting surface area, meanwhile, inwall inclined-plane and the fuel injector of the cone combustion chamber of the indent of two pistons formation are sprayed the spraying to be formed Angle just matches, and improves the air-fuel mixture uniformity, therefore, dynamic property, in theory economy, a significantly larger than conventional cylinder one The four of plug rush engine.

The each pair piston of the present invention do it is relative from be synchronized with the movement, active force and reaction force are balanced, meanwhile, Free wheels balance setting is employed, therefore complete machine operation is more steady, shakes smaller.And simultaneously, present invention eliminates inlet valve, row Valve switch and shock of the cam to push rod, and wind wheel booster engine is provided with exhaust gas turbine downstream, discarded flow velocity is reduced, from Noise source is reduced on source, therefore, more conventional engine noise is small.

Rationally, effect substantially, substantially increases the operating efficiency i.e. stability of Diesel engine to result of the present invention.
