Abstract
The utility model belongs to the technical field of cylinder caps, and particularly relates to a novel vortex type air-cooled diesel engine cylinder cap. The cylinder cap includes a cylinder body, a ventilating duct independently separating two air valve installing hole bases and an oil nozzle installing hole base is arranged between the upper end and the lower end of the cylinder body, the ventilating duct is communicated with outside to conduct heat out, air valve installing holes are arranged in the air valve installing hole bases, and an oil nozzle installing hole is arranged in the oil nozzle installing hole base. The ventilating duct provided can perform the heat radiation of the inside of an oil nozzle and the cylinder cap to reduce the heat in the oil nozzle and the cylinder cap, thereby achieving the effects of protecting the oil nozzle and reducing the temperature of the cylinder cover.
Description
Technical field:
The utility model belongs to cylinder head technical field, refers in particular to a kind of New Vortex formula air-cooled diesel engine cylinder head.
Background technique:
Current domestic air-cooled diesel engine be take direct spray type as main, and direct spray type air-cooled diesel engine cost is high, volume is large, Heavy Weight and discharge is poor, the life-span is long; The advantage such as vortex type air-cooled diesel engine has that cost is relatively low, volume is little, lightweight and emission performance is good.But due to vortex type air-cooled diesel engine oil nozzle and cylinder head fault higher, therefore on market, can not get client's approval, at present the state in stagnation.Vortex type air-cooled diesel engine oil nozzle and the higher main cause of cylinder head fault are: it is entity structure that vortex type air-cooled diesel engine cylinder head is used, the several radiating fin in outer surface contact cylinder head are dispelled the heat with air, radiating effect is very poor, cause cylinder head temperature higher, cause oil nozzle excess Temperature easily stuck, inlet and exhaust valve and cylinder cover valve guide pipe locking phenomenon.
Summary of the invention:
The purpose of this utility model is to provide ventilation flue in a kind of employing cylinder head oil nozzle and cylinder head inside is dispelled the heat; reduce the heat of oil nozzle and cylinder head, reach the New Vortex formula air-cooled diesel engine cylinder head of protection oil nozzle and the effect of the temperature of reduction cylinder head.
The utility model is achieved in that
A kind of New Vortex formula air-cooled diesel engine cylinder head, include cylinder body, between the top and bottom of cylinder body, be provided with two valve mounting hole seats and the independently divided ventilation flue of opening of oil nozzle mounting hole seat, heat is derived by ventilation flue and extraneous UNICOM, at valve mounting hole seat, is provided with on valve mounting hole, oil nozzle mounting hole seat and is provided with oil nozzle mounting hole.
The size at the middle part on above-mentioned heat dissipation channel between two valve mounting hole seats is less than the size at two ends, and two ends are respectively from the intake grill of leading flank and the exhaust outlet of trailing flank and the extraneous UNICOM of cylinder body.
One end of above-mentioned heat dissipation channel is provided with and is splay guide plate, guide plate is derived from intake grill importing, the heat of leading flank cold wind from the exhaust outlet of trailing flank, in the other end, be provided with oil nozzle mounting hole seat, in a side of oil nozzle mounting hole seat, be provided with several can be derived heat guide plate from the exhaust outlet of trailing flank.
The utility model compared to existing technology outstanding advantage is:
The ventilation flue of the utility model setting can dispel the heat oil nozzle and cylinder head inside, reduces the heat of oil nozzle and cylinder head, reaches the effect of the temperature of protection oil nozzle and reduction cylinder head.
Accompanying drawing explanation:
Fig. 1 is one of schematic perspective view of the present utility model;
Fig. 2 is two of schematic perspective view of the present utility model;
Fig. 3 is provided with the schematic diagram of inlet and outlet door and oil nozzle in cylinder head of the present utility model;
Fig. 4 is provided with the plan view of inlet and outlet door and oil nozzle in cylinder head of the present utility model;
Fig. 5 is the A-A sectional view of Fig. 4.
Embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 1-5:
A kind of New Vortex formula air-cooled diesel engine cylinder head, include cylinder body 1, between the upper end 2 of cylinder body 1 and lower end 3, be provided with two valve mounting hole seats 4 and the independently divided ventilation flue of opening 6 of oil nozzle mounting hole seat 5, ventilation flue 6 is derived heat with extraneous UNICOM, at valve mounting hole seat 4, is provided with on valve mounting hole 7, oil nozzle mounting hole seat 5 and is provided with oil nozzle mounting hole 8.
The size at the middle part on above-mentioned ventilation flue 6 between two valve mounting hole seats 4 is less than the size at two ends, and two ends are respectively by the intake grill 9,11 of leading flank and exhaust outlet 10,12 and the extraneous UNICOM of trailing flank of cylinder body 1.
One end of above-mentioned ventilation flue 6 is provided with and is splay guide plate 13, guide plate 13 is derived from intake grill 9 importings, the heat of leading flank cold wind from the exhaust outlet 10 of trailing flank, in the other end, be provided with oil nozzle mounting hole seat 5, in a side of oil nozzle mounting hole seat 5, be provided with several can be derived heat guide plate 14 from the exhaust outlet 12 of trailing flank.Guide plate 14 is provided with three, and be arranged in parallel.
The ventilation flue 6 of the utility model setting can dispel the heat to oil nozzle and cylinder head inside; reduce the heat of oil nozzle 15 and cylinder head; reach the effect of the temperature of protection oil nozzle 15 and reduction cylinder head; solved because cylinder head temperature is higher, caused oil nozzle 15 excess Temperatures easily stuck, intake valve 16, exhaust valve 17 and cylinder cover valve guide pipe locking phenomenon.
Working principle of the present utility model is:
During diesel engine work, outside air forms wind-force by air-cooled blade rotation, then by wind scooper, cold wind is imported to intake grill 9,11, after the inner loop of cylinder head, the heat of cylinder head is discharged from exhaust outlet 12,10.
Above-described embodiment is only one of preferred embodiment of the present utility model; not with this, limit practical range of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
