Abstract
A cylinder cover with a forced cooling water channel is arranged in a nose area, a forced cooling water hole in the nose area is arranged on the cylinder cover, a spraying end of the forced cooling water hole in the nose area is opposite to the nose area of the cylinder cover, the other end is close, one end of a vertical hole is communicated with the cooling water channel of a cylinder body, and the other end of the vertical hole is communicated with the forced cooling water hole in the nose area, the aperture size of the forced cooling water channel in the nose area can be set by manual; because each nose area of the cylinder is arranged with the forced cooling water channel of the nose area, cooling water in the water channel of the cylinder body flows from the vertical hole into the forced cooling water hole in the nose area, and directly sprays to the nose area on the cylinder cover, and carries out the forced cooling for each nose area on the cylinder cover, the aperture size of the forced cooling water channel in the nose area can be set by manual in order to ensure the cooling water in the hole having a certain flow rate, and sprays to the nose area where the heat load is the highest, strengthens to cool the high temperature area of the cylinder cover, reduces the thermal stress, prevents the baseboard surface of the cylinder cover from appearing a crack and a needle valve of an oil nozzle sticking, etc.
Description
Technical field:
The utility model relates to the component of diesel engine, specially refers to the cylinder head of diesel engine.
Background technique:
Cylinder head is a part very crucial on the diesel engine, its complex structure, because it directly contacts with cylinder block, thereby the heat load on it is very big, and the temperature difference between each point is very big, diesel engine is when work, the thermal stress of cylinder head is also bigger than mechanical stress, therefore must the design cooling water channel on cylinder head, and reasonable Arrangement water channel and organize cooling water flow, get rid of the cooling-water flow dead band, with the temperature of quick reduction cylinder.
In existing 2110 diesel engine cylinder head, because the structural design of cooling water channel is reasonable inadequately, intake valve guide hole in cylinder head, mounting hole of oil sprayer, in the bridge of the nose district that the exhaust valve guide hole is constituted, this regional temperature is the highest, people are referred to as the high-temperature zone, diesel engine is when high loaded process, superheating phenomenon can appear in cooling surface in bridge of the nose district, promptly can produce steam bubble at this regional cooling surface, destroyed the heat exchange between cylinder head wall body and the cooling water, caused cylinder head bridge of the nose district temperature drift, caused that oil nozzle head heat load increases the weight of, thereby the backplate surface of cylinder head is cracked, and serious also can cause injector valve stuck.
Summary of the invention
Goal of the invention of the present utility model is: provide a kind of bridge of the nose district to be provided with the cylinder head in forced cooling water road.
The utility model is realized the foregoing invention purpose by following technical solution.
The bridge of the nose described in the utility model district is provided with the cylinder head in forced cooling water road, comprise the tappet hole, the intake valve guide hole, mounting hole of oil sprayer, the exhaust valve guide hole, it is characterized in that: on cylinder head, also be provided with hole, forced cooling water road, bridge of the nose district, the water spray end in hole, forced cooling water road, described bridge of the nose district is to living by the intake valve guide hole, the bridge of the nose district that mounting hole of oil sprayer and exhaust valve guide hole are formed, the other end sealing, water inlet one end communicates with cooling water channel on the body, the other end communicates with hole, forced cooling water road, bridge of the nose district, and the pore size in hole, forced cooling water road, bridge of the nose district can artificially be set.
Owing to be equipped with hole, forced cooling water road, bridge of the nose district in the bridge of the nose district of each cylinder head, cooling water in the body water channel flows in the hole, forced cooling water road, bridge of the nose district from the water inlet, be directly injected to the bridge of the nose district of cylinder head, each bridge of the nose district to cylinder head forces cooling, the pore size in hole, forced cooling water road, bridge of the nose district can artificially be set, to guarantee that the cooling water in the hole has certain flow velocity, " bridge of the nose district " water spray the highest to heat load, reinforcement is to the cooling of cylinder head high-temperature zone, reduce thermal stress, prevent that effectively the cylinder head backplate surface from cracking and faults such as injector valve is stuck.
Description of drawings:
Fig. 1 is provided with the structural representation of the 2110 diesel engine cylinder head in forced cooling water road for bridge of the nose district.
Fig. 2 is an A-A sectional view among Fig. 1;
Among the figure: the 1-tappet bore; 2-intake valve guide hole; The 3-mounting hole of oil sprayer; 4-exhaust valve guide hole; The 5-water inlet; Hole, forced cooling water road, 6-bridge of the nose district; The 61-end of spraying water; 62-is silently little; 63-greatly silently;
Embodiment:
For example the utility model is elaborated below in conjunction with accompanying drawing:
The cylinder head that the bridge of the nose described in the utility model district is provided with the forced cooling water road is the two cylinder diesel engine cylinder head, it comprises tappet hole 1, intake valve guide hole 2, mounting hole of oil sprayer 3, exhaust valve guide hole 4, be equipped with hole, forced cooling water road, bridge of the nose district 6 in each bridge of the nose district of cylinder head, 61 pairs at the water spray end in hole, forced cooling water road, described bridge of the nose district 6 is lived by intake valve guide hole 2, the bridge of the nose district that exhaust valve guide hole 3 and mounting hole of oil sprayer 4 are formed, the other end is provided with little by silently 62, in the auxiliary hole of little silently 62 left end, be provided with greatly silently 63, water inlet 5 one ends communicate with cooling water channel on the body, the other end communicates with hole, forced cooling water road, bridge of the nose district 6, the pore size in hole, forced cooling water road, bridge of the nose district 6 can artificially be set, in this example, its aperture is 5mm.
The utility model is not limited only to the cylinder head of two cylinder diesel engine, and is practical equally to the cylinder head of single cylinder and multi-cylinder diesel engine.
