Abstract
The utility model discloses a cylinder head of a diesel engine cylinder in V type arrangement. The cylinder head of the diesel engine cylinder in the V type arrangement comprises a first oil return hole formed in the low end of the top of the cylinder head. As the oil return hole is formed in the low end of the top of the cylinder head, lubricating engine oil in a diesel engine adopting the cylinder in the V type arrangement can flow back and circulate smoothly, and the working performances of the diesel engine are further improved.
Description
Technical field
The utility model relates to the diesel engine field, and particularly a kind of V-type is arranged the cylinder head of cylinder of diesel engine.
Background technique
At present, most of diesel engines of arranging cylinder in upright arrangement, the machine oil of parts such as lubricated rocker arm body, valve spring can be got back in the body crankcase through the tappet bore on the cylinder head.For diesel engine (as shown in Figure 1) with respect to bent axle 1 V-shaped layout cylinder; The cylinder (not shown) is the V-shaped layout of relative tilt in two separate ranks, and cylinder head 2 just can not be got back to the body crankcase from the tappet bore on the cylinder head 2 at the machine oil of cylinder head 2 top low sides along with the inclination several angle is installed like this; And remain in the low side of the inclination of cylinder head 2; Cause the machine oil alluvial, can not smooth and easyly circulate, influence the running of diesel engine.
The model utility content
The technical problem that the utility model solves provides the cylinder head that a kind of V-type that can make the smooth and easy reflux cycle of lubricating oil of the diesel engine that V-type arranges cylinder is arranged cylinder of diesel engine.
For achieving the above object, the cylinder head that a kind of V-type that the utility model provides is arranged cylinder of diesel engine comprises: first spill port that is opened in cylinder head top low side.
Further, this cylinder head also comprises: second spill port that is opened in cylinder head bottom and links to each other with the 3rd spill port on the cylinder block, first spill port links to each other through the return tube assembly with second spill port.
Further, the exhaust side of cylinder head offers air starting auxiliary device mounting hole.
Further, the air inlet side of cylinder head offers the cylinder head exhaust port, and exhaust port links to each other with the cylinder head water channel.
According to the technological scheme of the utility model, because low side is offered spill port at the cylinder head top, can make V-type arrange the smooth and easy reflux cycle of lubricating oil of the diesel engine of cylinder, improve the service behaviour of diesel engine.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
Referring to Fig. 2 and Fig. 3; This V-type arranges that the cylinder head of cylinder of diesel engine comprises: be opened in the spill port 21 of cylinder head top low side and the spill port 22 of bottom; And the return tube assembly 3 that connects spill port 21 and spill port 22; Wherein, spill port 21 is positioned at the top low side of the cylinder head that tilts to install, and laterally runs through the sidewall of cylinder head; Make the machine oil of the cylinder head top low side alluvial that inclination is installed smooth and easyly to flow out (as shown in Figure 4); Vertically (above-below direction among Fig. 5) is provided with spill port 22 and links to each other with spill port (not shown) on the cylinder block, and the machine oil that spill port 21 flows out flows to spill port 22 through return tube assembly 3, after the spill port on the cylinder block be back to smoothly in the crankcase of cylinder block.
For motor, the low-temperature cool starting auxiliary device is generally all arranged, adopt the auxiliary device of startup that air preheat, air auxiliary starter etc. are arranged at present.The exhaust side of this cylinder head (spill port 21 1 sides among Fig. 2) has an air starting auxiliary device mounting hole 4; This mounting hole 4 communicates with cylinder (as shown in Figure 6); The pressurized gas that the air starting auxiliary device produces can enter into cylinder from cylinder head; And then the promotion piston motion, when low temperature, can reach the purpose that auxiliary engine starts.
The cooling system of motor is extremely important, when in the engine cooling water channel air being arranged, can influence cooling effect greatly.In order to address this problem; Air inlet side (downside of Fig. 7) in this cylinder head has a cylinder head exhaust port 5, and this exhaust port 5 links to each other with cylinder head water channel highest point (as shown in Figure 8), when in the water channel (not marking among the figure) air being arranged; Can be through the air in these exhaust port 5 eliminating water channels; Guarantee the cooling effect of the cooling system of motor, when normally using, this exhaust port 5 is for blocking state.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
