CN203452921U - Novel gasoline engine cylinder cover - Google Patents

Abstract

The utility model relates to a novel gasoline engine cylinder cover. The exhaust side of the cylinder cover is provided with a first waste gas recycling channel, a boss at the rear end of the cylinder cover is provided with a second waste gas recycling channel, and the first waste gas recycling channel is communicated with the second waste gas recycling channel. The novel gasoline engine cylinder cover is simple in structure and reasonable in design, reduces the number of parts in a waste gas recycling system, and reduces engine cost.

Description

A kind of new-typed gasoline engine cylinder head

Technical field

The utility model relates to a kind of cylinder head, particularly a kind of for the new-typed gasoline engine cylinder head on petrol engine.

Background technique

For reducing oxynitrides content in petrol engine discharging waste gas, increasing petrol engine adopts EGR Technology (EGR).But current used gas recirculation system component are more, complicated structure, thus cause motor cost to increase.

Summary of the invention

The purpose of this utility model is to overcome the deficiency existing in above-mentioned technology, provides a kind of simple in structure, reasonable in design, can reduce gas recirculation system amount of parts, reduces the new-typed gasoline engine cylinder head of motor cost.

In order to achieve the above object, the technical solution adopted in the utility model is: at cylinder head exhaust side, be processed with the first exhaust gas recirculation passage, in cylinder head rear end, boss place is processed with the second exhaust gas recirculation passage, and the first exhaust gas recirculation passage and the second exhaust gas recirculation passage communicate.

The utility model has the advantages that:

Simple in structure, reasonable in design, reduce gas recirculation system amount of parts, reduce motor cost.

Accompanying drawing explanation

Fig. 1 is the structural scheme of mechanism of the utility model recirculation line part;

Fig. 2 is the partial sectional view of the utility model recirculation line part.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

From Fig. 1-Fig. 2, the utility model is processed with the first exhaust gas recirculation passage 1 at cylinder head exhaust side, is processed with the second exhaust gas recirculation passage 2, the first exhaust gas recirculation passages 1 and the second exhaust gas recirculation passage 2 communicates at boss place, cylinder head rear end.

The utility model new-typed gasoline engine cylinder head, is processed with the first exhaust gas recirculation passage 1 at cylinder head exhaust side, at boss place, cylinder head rear end, is processed with the second exhaust gas recirculation passage 2, and both communicate.The utility model has reduced gas recirculation system amount of parts by the exhaust gas recirculation passage in cylinder head inside, has optimized structure, has reduced cost of production.

Claims (1)

1. a new-typed gasoline engine cylinder head, it is characterized in that: at cylinder head exhaust side, be processed with the first exhaust gas recirculation passage (1), at boss place, cylinder head rear end, be processed with the second exhaust gas recirculation passage (2), the first exhaust gas recirculation passage (1) and the second exhaust gas recirculation passage (2) communicate.
