Abstract
The utility model discloses the integrated morphology of a kind of engine cylinder cover and gas exhaust manifold, comprise the gas exhaust manifold (2) be communicated with the relief opening of engine cylinder cover (1), described gas exhaust manifold (2) and engine cylinder cover (1) are integrated casting and form, described gas exhaust manifold (2) is provided with four groups and arranges exhaust structure in a row, often organize exhaust structure and be provided with two exhaust charges (2.1), often organize two exhaust charges (2.1) and converge an exhaust passage, road, four groups of exhaust structures of described gas exhaust manifold (2) pool formation relief opening (2.2).After adopting above structure, because engine cylinder cover and gas exhaust manifold are the entirety that one is poured into a mould, because omitted herein the operation of both assemblings, also saving part required when both assemble, thus saving cost, improve the manufacture efficiency of product.
Description
Technical field
The utility model relates to technical field of engines, is specifically the integrated morphology of a kind of engine cylinder cover and gas exhaust manifold.
Background technique
At present, along with engine performance raising, Economy and emission performance laws and regulations requirement further add sternly, the startability of automobile is had higher requirement, so heat of engine divides pairing motor more and more important simultaneously.In prior art, engine cylinder cover and gas exhaust manifold are divided into two component, and wherein engine cylinder cover adopts aluminum alloy material casting, and gas exhaust manifold generally adopts steel, cast iron materials, and the higher supercharging of delivery temperature or supercharging injection machine type, the high-nickel material of employing.But the shortcoming existing for this traditional structure is:
1) because delivery temperature is very high, just need many oil spouts to reach in the higher operating mode of row's temperature the object reducing row's temperature, but oil consumption is corresponding just to improve greatly;
2) this engine cylinder cover and gas exhaust manifold split-type structural, the cylinder pad that intermediate demand is required by higher material connects, need heat-resisting high-strength bolt fastening simultaneously, the risk of gas leakage will be there is in the connection between such two parts, and once gas leakage, be larger to the performance impact of motor, especially supercharging type, booster performance declines to a great extent, and engine performance reduces rapidly;
3) motor is when startup or idling operation, main heat transmission comes from exhaust, but gas exhaust manifold cannot return more heat transmission to cylinder cap and engine cylinder-body, so engine temperature is just difficult to be improved rapidly, startup performance of engine will be affected, engine consumption and discharge all can raise greatly, are unfavorable for energy-saving and emission-reduction.
Model utility content
Technical problem to be solved in the utility model is, the integrated morphology of a kind of engine cylinder cover and the shaping engine cylinder cover of gas exhaust manifold integrally casting and gas exhaust manifold is provided, thus solve the too high problem of exhaust manifold temperature, improve idling and the startability of motor.
For solving the problems of the technologies described above, the integrated morphology of the engine cylinder cover that the utility model provides and gas exhaust manifold, comprise the gas exhaust manifold be communicated with the relief opening of engine cylinder cover, described gas exhaust manifold and engine cylinder cover are integrated casting and form, described gas exhaust manifold is provided with four groups and arranges exhaust structure in a row, often organize exhaust structure and be provided with two exhaust charges, often organize two exhaust charges and converge an exhaust passage, road, four groups of exhaust structures of described gas exhaust manifold pool formation relief opening.
Gap is provided with between two exhaust charges of each group.
Described relief opening is positioned at the below in the center portion of four groups of exhaust structures.
The outside of outermost two groups of exhaust structures of described gas exhaust manifold is provided with cooling water channel, and be also provided with cooling water channel between two adjacent groups exhaust structure, all cooling water channels are communicated with mutually.
After adopting above structure, the utility model compared with prior art, has the following advantages:
1) because engine cylinder cover and gas exhaust manifold are the entirety that one is poured into a mould, because omitted herein the operation of both assemblings, also saving part required when both assemble, thus saving cost, improve the manufacture efficiency of product;
2) delivery temperature of gas exhaust manifold is also transmitted by engine cylinder cover, therefore, solves the problem that exhaust manifold temperature is too high, can reach the air fuel ratio that motor is rarer, reduces engine consumption;
3) when the temperature of gas exhaust manifold be delivered to engine cylinder cover time, engine temperature will be improved very soon, and like this, idling performance and the startability of motor are just raised greatly, therefore, the oil consumption of motor and emission performance can further be optimized.

From the structural representation of the integrated morphology of the utility model engine cylinder cover shown in accompanying drawing 1 and gas exhaust manifold, it comprises the gas exhaust manifold 2 be communicated with the relief opening of engine cylinder cover 1, described gas exhaust manifold 2 is integrated casting with engine cylinder cover 1 and forms, described gas exhaust manifold 2 is provided with four groups and arranges exhaust structure in a row, often organize exhaust structure and be provided with two exhaust charges 2.1, often organize two exhaust charges 2.1 and converge an exhaust passage, road, four groups of exhaust structures of described gas exhaust manifold 2 pool formation relief opening 2.2.
Gap 3 is provided with between two exhaust charges 2.1 of each group.
Described relief opening 2.2 is positioned at the below in the center portion of four groups of exhaust structures.
The outside of outermost two groups of exhaust structures of described gas exhaust manifold 2 is provided with cooling water channel 4, is also provided with cooling water channel 4 between two adjacent groups exhaust structure, and all cooling water channels 4 are communicated with mutually.
The above; it is only the better feasible exemplifying embodiment of the utility model; therefore interest field of the present utility model can not namely be limited to; concerning those of ordinary skill in the art, other various corresponding changes that all utilization the technical solution of the utility model and technical conceive are made all should belong within the protection domain of the utility model claim.
