Abstract
The utility model belongs to the field of diesel engine cylinder heads, and particularly relates to a medium-speed diesel engine cylinder head. The medium-speed diesel engine cylinder head comprises air-in valves, exhaust valves, an air-in passage, an exhaust passage, an oil supply hole and an oil atomizer installation hole. The medium-speed diesel engine cylinder head is characterized in that the air-in valves and the exhaust valves are respectively two in number, a push rod hole is respectively arranged in each side of the air-in passage, and the oil supply hole is arranged between the push rod holes. The push rod hole is respectively arranged in each side of an oil jet hole of the cylinder head, the medium-speed diesel engine cylinder head is compact in structure, and therefore the air-in passage and the exhaust passage of the cylinder head can be arranged easily, and an oil jet cam shaft and a distribution cam shaft can be combined into one. With the design of a single cam shaft, an air-inlet cam and an exhaust cam are arranged on two sides of an oil jet cam, and the cylinder head and a whole engine are simple and compact in structure. In addition, the medium-speed diesel engine cylinder head has the advantages of being low in processing cost and large in discharge coefficient.
Description
Technical field
The utility model belongs to the cylinder cover for diesel engine field, relates in particular to a kind of medium speed diesel cylinder head.
Background technique
The Injection Pump of most of medium speed diesels adopts mechanical monoblock pump in the market; In the design of camshaft, its injection cam axle and distribution cam axle are arranged in the cylinder block both sides respectively to make things convenient for the complete machine structure layout, perhaps injection cam axle and distribution cam axle are combined into single camshaft.No matter adopt the double joint camshaft design, still use single camshaft, all need corresponding cylinder head to finish the work.
Two camshaft design of available technology adopting have increased cylinder head Assembly part quantity and cost; It is complicated that the single camshaft design proposal then makes four valve cylinder head intake and exhaust ports arrange; Need porting be arranged in the cylinder cap homonymy, drive the rocking arm rotation through mechanisms such as tappet, push rods then, close thereby drive valve opening; Not only can increase the complexity and the casting difficulty of cylinder cap design, also can be difficult to the bigger intake duct of layout design outflow coefficient.
The model utility content
In order to overcome the above-mentioned technical problem of medium speed diesel, the utility model be to provide a kind of simple in structure, arrange the medium speed diesel cylinder head compact, that processing cost is low and flow coefficient is big.
The medium speed diesel cylinder head that the utility model adopts; Comprise air intake valve, drain tap, intake duct, air outlet flue, oil inlet hole, mounting hole of oil sprayer; It is characterized in that: each two of air intake valve and drain taps, the intake duct both sides respectively are provided with a push-rod hole, and oil inlet hole is between push-rod hole.
Arrange two push-rod holes in cylinder cap nozzle opening both sides; Compact structure; Make the cylinder cap intake and exhaust port easily arrange and make oil spout and distribution cam axle to unite two into one, the design of this single camshaft is arranged in the injection cam both sides with intake and exhaust cam, makes cylinder cap and compact integral structure.
Oil inlet hole, inlet hole and push-rod hole are in the same side in the utility model.
Cylinder head slanted pushing rod hole described in the utility model is oblique 8 °, and the oil inlet hole position can be in the middle of push-rod hole, also below intake duct.
The cylinder head body adopts four valves to arrange, push-rod hole and cylinder cap all directly are cast as one, and the push-rod hole major part need not processed, and only needs to cut down finished cost descending the stomidium partial operation can guarantee cooperating of push-rod hole and dependency structure.
Oil inlet hole directly is arranged in the intake duct below, is not influencing the structural configuration that easily realizes nozzle opening basically of inlet duct flow flow coefficient.
In addition, intake and exhaust port is arranged in the both sides of oil sprayer, has guaranteed that effectively the high-power diesel engine flow coefficient will enough big designing requirement.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
Medium speed diesel cylinder head in the utility model, cylinder head body adopt four valves to arrange, air intake valve 1 and drain tap 2 each two also comprise intake duct 4, air outlet flue 5, oil inlet hole 6 and mounting hole of oil sprayer 7.
And intake duct 4 both sides respectively are provided with a push-rod hole 3, and push-rod hole 3 is oblique 8 °.Oil inlet hole 6 positions also are arranged in intake duct 4 belows in the middle of push-rod hole 3.Push-rod hole 3 all directly is cast as one with cylinder cap.Oil inlet hole 6, intake duct 4 and push-rod hole 3 are in the same side, and intake duct 4 and air outlet flue 5 are arranged in the both sides of oil sprayer.
Arrange two push-rod holes 3 in cylinder cap oil inlet hole 6 both sides; Make cylinder head intake duct 4 and air outlet flue 5 easily arrange and make oil spout and distribution cam axle to unite two into one; The design of this single camshaft is arranged in the injection cam both sides with intake and exhaust cam, makes cylinder cap and compact integral structure.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
