Abstract
The utility model relates to a cylinder head of diesel engine, comprising a valve, a installation seat of camshaft, a cooling water channel, an intake port (7) and an exhaust port (8). The cylinder head is equipped with a push rod hole (3) and installation hole of spark plug. The intake port (7) is the sprial structure. The cylinder head is equipped with four drilling hole (6), which has one end communicated with the cooling water channel and the other end communicated with the bridge zone of the cylinder head. The cylinder head corresponding to each cylinder is equipped with a bottom hole of the exhaust valve seat (1) and a bottom hole of the suction valve seat (2). The utility model obtains various swirl ratio and flow coefficient and meets EU II and EU III emission requirements by adjusting the swirl ration. In addition, the utility model adjusts reasonably the relvant dimensions and consequently reduce the manufacture cost under the premise of meet the requirement of the engine.
Description
Technical field
The utility model relates to a kind of parts of motor, relates to a kind of cylinder cap of diesel engine specifically.
Background technique
The effect of cylinder head is the common bags that forms of blanket gas cylinder sleeve and piston, and mechanical stress of bearing and thermal stress are very big.The intake duct structure and layout of diesel engine are also unreasonable at present, and its structure often makes motor can not obtain comparatively ideal swirl rate and guarantees high charging efficiency.Make motor vehicle exhaust emission can't reach specified standard.Because the design of size of engine also makes under the situation that satisfies other requirements of motor, can't reasonably reduce manufacture cost.
The model utility content
The utility model has designed and developed out can obtain more satisfactory swirl rate and guaranteeing high charging efficiency at the deficiencies in the prior art, makes motor vehicle exhaust emission reach specified standard, and rationally reduces the diesel engine cylinder cap of manufacture cost.
The utility model is achieved through the following technical solutions:
A kind of diesel engine cylinder cap comprises the fitting seat of valve, camshaft, cooling water passage, and intake duct and air outlet flue are provided with the mounting hole of push-rod hole and spark plug in the cylinder cap, and its intake duct is a helicoidal structure; Cylinder cap is provided with boring, and an end of boring is connected with cooling water passage, and the other end of boring is connected with cylinder cap bridge of the nose district.
A kind of diesel engine cylinder cap, its boring are provided with four, and the diameter of boring is ￠ 8mm-￠ 9mm.
A kind of diesel engine cylinder cap, the pairing cylinder cap of each cylinder are provided with an exhaust valve seat insert bottom outlet and an inlet valve seat ring bottom outlet.
A kind of diesel engine cylinder cap, its cylinder head height is 88mm-95mm, the inlet and outlet door line of centres is apart from cylinder centerline 7mm-9mm, inlet and outlet door spacing 47mm-49mm, mounting hole of oil sprayer and Vertical direction tilt 9 °-11 °.
A kind of diesel engine cylinder cap, its cylinder head base plate thickness is 11mm-14mm, electric heating consent setting angle is 25 °-28 ° of space angles.
A kind of diesel engine cylinder cap, its push-rod hole angle are 38 °-42 °.
The size of the utility model engine cylinder cover is little, combustion-chamber shape is simple, low cost of manufacture, under the prerequisite that does not change jacket structure for water by obtaining different swirl rates and circulation coefficient to local adjustment in the structure that adopts spiral inlet duct and the spiral inlet duct, satisfy the requirement of Europe II, Europe III discharging by the swirl rate adjustment, two valves the complex structure degree that can effectively reduce distribution device is set, reduce cost.Adopt 4 Φ, 9 borings that cooling water is imported cylinder cap bridge of the nose district and cool off, the cylinder cap thermal fatigue resistance is increased substantially, casting technique is required greatly to reduce.Under the prerequisite that satisfies the motor oneself requirement, reasonably adjust relevant size in addition, so also reduced manufacture cost.

Embodiment
Referring to accompanying drawing 1,2,3.
The utility model comprises the fitting seat of valve, camshaft, cooling water passage, and intake duct (7) and air outlet flue (8), and the mounting hole of spark plug, its intake duct (7) is a helicoidal structure; Cylinder cap is provided with four borings (6), and an end of boring (6) is connected with cooling water passage, and the other end of boring (6) is connected with cylinder cap bridge of the nose district.The diameter of boring (6) is ￠ 9mm.The pairing cylinder cap of each cylinder is provided with an exhaust valve seat insert bottom outlet (1) and an inlet valve seat ring bottom outlet (2).The cylinder head height is 92mm, and the inlet and outlet door line of centres is apart from cylinder centerline 8mm, inlet and outlet door spacing 48mm, and mounting hole of oil sprayer (4) tilts 10 ° with Vertical direction.The cylinder head base plate thickness is 13mm, and electric heating consent (5) setting angle is 25 ° of space angles and 28 °.Push-rod hole (3) angle is 40 °.
The utility model can obtain different swirl rates and circulation coefficient, satisfies the requirement of Europe II, Europe III discharging by the swirl rate adjustment.Under the prerequisite that satisfies the motor oneself requirement, reasonably adjust relevant size in addition, so also reduced manufacture cost.
