Abstract
The invention relates to an improved cylinder head cover of a diesel engine, which comprises a head cover body, wherein the head cover body is formed by four side surfaces of the head cover and a flat surface of the head cover; and a row of reinforcing ribs perpendicular to the flat surface of the head cover is respectively arranged at the outer part and the inner part of the side surfaces of the head cover. The improved cylinder head cover has the advantages of good anti-seismic performance and good noise reduction effect.
Description
Technical field
The present invention relates to a kind of valve mechanism cover, be specifically related to a kind of valve mechanism cover that is installed in the DENG.
Background technique
Valve mechanism cover is one of major part on the engine cylinder-body, plays the function to blanket gas cylinder cap and isolated outside contamination.When piston moved in cylinder, engine interior can gather stronger pressure, leaked thereby produce; Cause valve mechanism cover to produce vibrations and produce noise; Valve mechanism cover main employing working of plastics making on petrol engine at present, some large-scale valve mechanism cover originally also all adopted working of plastics to make on the DENG, though working of plastics is low weight, the noise of generation is also less; But working of plastics is easy ageing under the condition of long term high temperature, produces to leak, influence working life.
The valve mechanism cover that existing a kind of aluminium alloy compression casting is made; But because the power of DENG is very big; Be up to more than 500 horsepowers, because the Placement that valve mechanism cover is taked with cylinder body is essentially hard connection, the piston in the motor running at full capacity in the cylinder body is through the diesel oil knocking fuel of mist in the firing chamber; Emit fierce expansion, the pressure rising of gas generation in the significant amount of energy cylinder; Thereby make cylinder body produce violent vibrations, send very big noise, influenced the machine performance index.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, a kind of improved diesel engine cylinder housing of antidetonation flat is provided.
Technological scheme: in order to solve the problems of the technologies described above; Improved diesel engine cylinder housing of the present invention; It comprises cover cap itself; This cover cap itself is made up of four cover cap sides and a cover cap plane, respectively is provided with row's stiffening rib, this stiffening rib and vertical setting the in said cover cap plane in the outside and the inside of said cover cap side.
Said stiffening rib is fin-shaped stiffening rib or long strip stiffening rib.
Be provided with oil gas preseparator chamber in the inside of said cover cap own, this oil gas preseparator chamber is connected with the oil gas preseparator, and one end is provided with oil gas preseparator return tube in said oil gas preseparator chamber.
Originally be provided with attachment hole on one's body at said cover cap, be provided with stiffening rib in these attachment hole two edges.
The material of said cover cap itself is an aluminum alloy.
Through increase row stiffening rib arranged side by side in the side, when the motor running at full capacity,, play good bradyseism, noise reduction effect through the shock-absorbing of inside and outside double-deck stiffening rib, dropped to 65-75dB to noise from 85-92dB.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: through originally establishing stiffening rib on one's body at cover cap, make motor when running at full capacity, vibrations that difficult generation is bigger and noise can satisfy the use standard.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; A kind of improved diesel engine cylinder housing of the present invention; It comprises cover cap itself 1; This cover cap itself 1 is made up of four cover cap sides 2 and a cover cap plane 3, it is characterized in that: outside and inside in said cover cap side 2 respectively are provided with row's stiffening rib 4, this stiffening rib 4 and the 3 vertical settings of said cover cap plane; Said stiffening rib 4 is fin-shaped stiffening rib or long strip stiffening rib; Be provided with oil gas preseparator chamber 5 in said cover cap 1 inside itself, this oil gas preseparator chamber 5 is connected with oil gas preseparator 6, and 5 one ends are provided with oil gas preseparator return tube 7 in said oil gas preseparator chamber; On said cover cap itself 1, be provided with attachment hole 8, be provided with stiffening rib 4 in these attachment hole 8 two edges; The material of said cover cap 1 itself is an aluminum alloy.The present invention makes motor when running at full capacity through originally establishing stiffening rib on one's body at cover cap, and vibrations that difficult generation is bigger and noise can satisfy the use standard.
The present invention does not relate to all identical with the existing technology existing technology that maybe can adopt of part and realizes.
