Technical field

The utility model belongs to technical field of internal combustion engines, is specifically related to a kind of supercharge cylinders device for diesel engine.

Background technique

Diesel engine is the one of internal-combustion engine, mixes in diesel injection to cylinder with air, and high temperature when being compressed to terminal by air in cylinder exceedes diesel oil burning-point and starts the heat engine of work.In the aspirating stroke of diesel engine, intake valve is opened, exhaust valve closing, by piston inhale fresh air for burning is ready, wherein, whether sufficient cylinder air air inflow is is one of key factor affecting diesel engine oil consumption, for guaranteeing that oil inflame is abundant, improve air inflow, when not changing volume, usually adopt the mode such as air compressor supercharging or mechanical supercharger to realize, and these modes realize difficulty and structure manufacture cost all too high, and the loss that causes of power to export motor is excessive, is therefore necessary to improve.

Model utility content

The technical problem that the utility model solves: a kind of supercharge cylinders device for diesel engine is provided, by easy structure when the diesel engine constancy of volume for providing sufficient tolerance in cylinder, enable fuel oil Thorough combustion, correspondingly play the effect reducing oil consumption, improve engine power performance and Economy.

The technical solution adopted in the utility model: for the supercharge cylinders device of diesel engine, described diesel engine has diesel engine box body, the bent axle of the diesel engine of diesel engine box body is stretched out in end, drive by bent axle and to rotate and the camshaft of engine housing is stretched out in end, and the cylinder to be connected with diesel engine box body, the axle head of described camshaft is provided with roller, the wheel disc of roller is fixed with axle, one end of crank is connected with axle by bearing, the end of the hinged piston rod of the other end of crank, the other end of piston rod is connected with the inflator adaptation being fixed on diesel engine outside, the outlet side of inflator connects tracheae, the outlet side of tracheae is communicated with the cylinder of diesel engine distribution device.

Described camshaft provides power source by the bent axle in diesel engine connecting rod, is rotated by the transmission of camshaft drive.

The utility model advantage compared with prior art:

1, power resources are rotated to be with the camshaft of diesel engine, by the constantly to-and-fro motion of the piston rod in crank handle turns inflator to supplement cylinder of diesel engine tolerance, the internal pressure of effective raising cylinder of diesel engine, make fuel oil Thorough combustion, improve the rate of combustion of fuel oil, reduce average fuel consumption, improve the Economy of diesel engine;

2, this device is more simple compared with remaining cylinders boosting system arrangement, volume is more small and exquisite, and be easy to realize, cost is low, and operating range is wide, required driving force is provided by diesel engine itself, is no matter low speed or runs up and can obtain certain suction pressure.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is mounting structure schematic diagram of the present utility model.

Embodiment

Below in conjunction with accompanying drawing 1-2, a kind of embodiment of the present utility model is described.

For the supercharge cylinders device of diesel engine, described diesel engine has diesel engine box body 12, the bent axle 9 of the diesel engine of diesel engine box body 12 is stretched out in end, drive by bent axle 9 and to rotate and the camshaft 1 of engine housing 12 is stretched out in end, and the cylinder 11 to be connected with diesel engine box body 12, diesel engine connecting rod is provided with in described diesel engine box body 12, diesel engine distribution device, oil-fired system, lubrication system, cooling system and electric system, wherein, the casing 12 of diesel engine is as supporting and the skeleton of mounting diesel engine miscellaneous part, by diesel engine connecting rod as major moving parts, the energy produced by its burning passes through connecting rod, bent axle 9, flywheel 10 etc. is transformed into mechanical energy and passes, camshaft 1 in diesel engine distribution device and bent axle 9 are by camshaft drive (such as intermediate gear, the gear transmission of timing gear composition) connect, namely described camshaft 1 provides power source by the bent axle 9 in diesel engine connecting rod, rotated by the transmission of camshaft drive, concrete linkage structure is prior art, therefore not to repeat here, simultaneously, in diesel engine distribution device, camshaft 1 is as control valve opening, closed parts, its mounting point that is concrete and bent axle 9 (is above put, mid-or underlying) and therefore not to repeat here with the linkage structure of valve, as shown in Figure 2, for agricultural diesel oil motor under prior art, the innovative point of the present embodiment is: the roller 2 of axle head installation with camshaft 1 synchronous rotary stretching out diesel engine box body 12 at described camshaft 1, the wheel disc of roller 2 is fixed with an axle 3, axle 3 is minor axis, and axle 3 does radial circumference with the rotation of roller 2 along camshaft 1 moves, axle 3 is installed bearing 4, one end of the outer ring connecting crank 5 of bearing 4, one end of the hinged piston rod 601 of the other end of crank 5, the adaptive inflator 6 of piston rod 601, the other end of piston rod 601 is provided with piston, and piston is reciprocating in the cylinder chamber of inflator 6 under the drive of crank 5, the outside of inflator 6 is fixedly installed in the outside of diesel engine box body 12 by mounting plate 8 and fastening piece, the outlet side 602 of inflator 6 connects a tracheae 7, the outlet side of tracheae 7 can be connected with the inlet end of the cylinder 11 of diesel engine distribution device.

Utility model works principle is: the power source rotated as camshaft 1 by the rotation of bent axle 9, rotated by the driving belt moving cam axle 1 of camshaft drive, the roller 2 rotarily driving its axle head of camshaft 1 rotates, the rotation of roller 2 drives crank 5 one end to move along camshaft 1 as radial circumference, meanwhile, the piston rod 601 hinged with crank 5 the other end makes suction movement in the cylindrical shell of inflator 6, and air is filled with the tolerance removing to increase cylinder 11 in the cylinder 11 of diesel engine by inflator 6 through tracheae 7.

In sum, the utility model rotates to be power resources with cam shaft for diesel engine 1, drive the piston rod 601 in inflator 6 reciprocating to supplement cylinder of diesel engine 11 tolerance by crank 5, the internal pressure of effective raising cylinder of diesel engine 11, make fuel oil Thorough combustion, improve the rate of combustion of fuel oil, reduce average fuel consumption, improve the Economy of diesel engine; And this device is more simple compared with all the other boosting system arrangement, directly can be installed on the outside of diesel engine box body 12, there is compact, be easy to realize, cost is low, operating range is wide, required driving force is provided by diesel engine itself, is no matter low speed or runs up and can obtain certain suction pressure.
