Abstract
The utility model discloses an air cylinder head cover of an engine. A main body of the air cylinder head cover is a plastic injection molding piece. Protecting layers are arranged on the external surface and the internal surface of the air cylinder head cover. As the air cylinder head cover adopts the plastic injection molding piece, the integral weight of the engine is reduced, the engine noise is decreased, the manufacturing cost is low, and the integral cost of the engine can be reduced. A labyrinth-type oil and gas separating device is arranged on the air cylinder head cover, so that the oil and the gas of the waste gas in a crankcase can be favorably separated. In a hollow cavity of a main body of the air cylinder head cover, the labyrinth in the labyrinth-type oil and gas separating device is made from the same material as the air cylinder head cover and is integrally formed with the air cylinder head cover. The air cylinder head cover is easy to form and has better process property.
Description
Technical field
The utility model belongs to the technical field of vehicular engine, and specifically, the utility model relates to the valve mechanism cover of motor.
Background technique
Vehicular engine valve mechanism cover fundamental function is to hide and the blanket gas cylinder cap, and machine oil is remained on inside, simultaneously with contaminants such as dirt and moisture in outside, the also normally the most difficult ready-made aspect; Valve mechanism cover is also isolated with machine oil and air simultaneously, forms mist of oil in the operation process of motor, and the colder internal surface of valve mechanism cover is assembled the oil-collecting mist, makes the machine oil condensation and flows back to the machine oil shell downwards; Valve mechanism cover is also taken into account the functions such as effect that make crankcase ventilation simultaneously.And the valve mechanism cover of motor generally is to be made by aluminum alloy material at present, because the density of aluminum alloy is relatively large, and the ability of the valve mechanism cover absorbing vibration that aluminum alloy is made is relatively poor relatively.The density of aluminum alloy is relatively large, and weight causes the overall weight of motor big greatly, and the performance of its absorbing sound and lowering noise is also relatively poor relatively, and the noise of the motor of use aluminum alloy material making valve mechanism cover is also relatively large.
The model utility content
Technical problem to be solved in the utility model provides a kind of valve mechanism cover that can reduce the motor overall weight, reduce engine noise.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of engine air cylinder cap, the body of described valve mechanism cover are plastic injection piece, are provided with protective layer at the outer surface and the internal surface of this cylinder cover.
On the protective layer of the outer surface of described valve mechanism cover, be provided with decorative layer.
On described valve mechanism cover, be provided with labyrinth oil gas separator, be positioned at the body cavity of this valve mechanism cover.
Labyrinth in the described labyrinth oil gas separator and described cylinder head cover constitute for the homogeneity one.
Advantage of the present utility model is to adopt the valve mechanism cover of plastic injection piece, not only can reduce the motor overall weight and reduce engine noise, and for the Oil-gas Separation in the crankcase, be convenient in valve mechanism cover, arrange the labyrinth in the labyrinth oil gas separator, moulding easily, manufacturability is better; Adopt the valve mechanism cover of plastic injection piece, low cost of manufacture, the whole cost of reduction motor.
Description of drawings
Fig. 1 is the utility model structural representation, and arrow is represented airflow direction among the figure;
Mark among the above-mentioned figure is: 1, valve mechanism cover; 2, labyrinth oil gas separator.
Embodiment
As shown in Figure 1, a kind of engine air cylinder cap, the body of this valve mechanism cover 1 are plastic injection piece, be provided with protective layer at the outer surface and the internal surface of this cylinder cover, and be provided with decorative layer on the protective layer of its outer surface.
For the waste gas that helps in the crankcase carries out Oil-gas Separation, on this valve mechanism cover 1, be provided with labyrinth oil gas separator 2, be positioned at the body cavity of this valve mechanism cover 1, labyrinth in the labyrinth oil gas separator 2 and this valve mechanism cover 1 constitute for the homogeneity one, moulding easily, manufacturability is better.
By adopting the valve mechanism cover 1 of plastic injection piece, not only can reduce the motor overall weight and reduce engine noise, and low cost of manufacture, can reduce the whole cost of motor.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
