Description

Cylinder cover component and automobile engine

Technical Field

The utility model relates to the technical field of automobile engines, in particular to a cylinder cover component and an automobile engine.

Background

Most engines in the market at the early stage adopt independent exhaust manifolds as the connection between a cylinder cover and exhaust aftertreatment, the arrangement mode is limited by the space of a cabin on one hand and the cold start emission on the other hand, and therefore a scheme of integrating the exhaust manifolds with the cylinder cover is developed. For a four-cylinder engine in the prior art, a cylinder cover of an integrated exhaust manifold is in a structural form of a four-in-one integrated exhaust passage, and the structure has the following problems: the ignition sequence of a general four-cylinder engine is 1-3-4-2, for example, when a first cylinder starts to exhaust after combustion, a third cylinder starts to combust and then exhaust, when the first cylinder does not exhaust completely, and the third cylinder starts to exhaust, the first cylinder is susceptible to influence waste to flow backwards into a combustion chamber, so that exhaust interference is generated, and the performance of an engine is poor.

SUMMERY OF THE UTILITY MODEL

The first object of the present invention is to: aiming at the problem that in a four-cylinder engine in the prior art, a cylinder cover adopts a four-in-one integrated exhaust passage form, exhaust interference can be generated among cylinders in the form, and the performance of the engine is poor, a cylinder cover component is provided; a second object of the present invention is to provide an automotive engine.

In order to achieve the first object, the utility model adopts the technical scheme that:

the cylinder cover component comprises a cylinder cover body, wherein four exhaust passages which are respectively communicated with four cylinders are arranged in the cylinder cover body, two of the four exhaust passages which are communicated with two cylinders at the front end and the rear end are converged into one exhaust passage, and extend to the surface of the cylinder cover body to form a first exhaust port; two of the four exhaust passages communicated with the two cylinders in the middle are converged into one passage and extend to the surface of the cylinder cover body to form a second exhaust port.

According to the utility model adopting the technical scheme, four exhaust passages are integrated in the cylinder cover, two communicated with the two cylinders at the front end and the rear end are converged into one, and two communicated with the two cylinders at the middle end are converged into one, compared with the prior art that the cylinder cover adopts a four-in-one integrated exhaust passage form, the exhaust interference can be generated among the cylinders in the form, and the problem of poor engine performance is caused.

Furthermore, the surface of the cylinder cover body is provided with a mounting surface, the first exhaust port and the second exhaust port are arranged on the mounting surface, and the mounting surface is used for mounting an exhaust gas receiving device.

Furthermore, the first exhaust port and the second exhaust port are arranged up and down, so that the bending of the exhaust passage is reduced as much as possible, and the exhaust effect is better.

Furthermore, two exhaust passage air inlets are arranged at the communication positions of any one of the four exhaust passages and the corresponding cylinder and are respectively communicated with two exhaust ports of the cylinder.

Furthermore, the cylinder cover body is integrally formed through casting, the structure of the cylinder cover body with the exhaust passage is complex, and efficient production is achieved through casting.

In order to achieve the second purpose, the utility model adopts the following technical scheme:

an automobile engine comprises the cylinder cover component.

Compared with the prior art, the utility model has the beneficial effects that: the exhaust influence among cylinders is reduced, exhaust interference is avoided, single-cylinder exhaust pulse energy is effectively utilized, and the performance of the engine is improved.
