Description
Technical field
The utility model is related to engine art more particularly to a kind of cylinder head.
Background technology
When the engine is working, the gasket installed between valve mechanism cover and cylinder head is easy the height in exhaust pipe and booster
The lower aging of temperature radiation.Traditional anti-aging way is that replaceable thermal insulation board is installed between valve mechanism cover and booster, still
The parts of engine can thus be increased, and replace thermal insulation board and also bother, there are also other producers, are leaned in cylinder head
The place of nearly gasket opens up a bosh penetrated through with cooling jacket, for being cooled down to gasket, but for a long time
After use, gasket still will appear aging phenomenon, ineffective.
Utility model content
The technical problem to be solved by the embodiment of the utility model is, for being installed between valve mechanism cover and booster
Replaceable thermal insulation board can increase the parts of engine, and replace thermal insulation board and also bother, and in cylinder head close to gasket
Place opens up a bosh penetrated through with cooling jacket, and for being cooled down to gasket, after prolonged use, gasket is also
It is that will appear aging phenomenon, a kind of ineffective problem, it is proposed that cylinder head.
In order to solve the above-mentioned technical problem, the utility model embodiment provides a kind of cylinder head, which includes：Gas
Cylinder cap offers multilayer at upper part port and gets out of a predicament or an embarrassing situation, offer and get out of a predicament or an embarrassing situation at the lower port of valve mechanism cover it is matched on
Step, valve mechanism cover are buckled in cylinder head, top bar and gasket are equipped between getting out of a predicament or an embarrassing situation, top bar and get out of a predicament or an embarrassing situation it is right respectively
The opening being oppositely arranged is offered on the outer wall of the valve mechanism cover and cylinder head answered, heat shield is embedded in two openings, court
Protrusion is provided with to one end inside cylinder head between protrusion is inserted into top bar and gets out of a predicament or an embarrassing situation with gasket interval to be arranged.
Wherein, it gets out of a predicament or an embarrassing situation and is provided with three layers.
Wherein, multiple convex ball points are provided on a side surface of the heat shield far from gasket.
Wherein, sink is equipped in valve mechanism cover, sink is connected to the cooling jacket in cylinder head.
Wherein, the thickness of heat shield is more than the depth.
Implement the utility model embodiment, has the advantages that：A kind of cylinder head of the utility model, is not only arranged
With cooling jacket is close gets out of a predicament or an embarrassing situation, heat shield is also mounted between step, not only to the good cooling results of gasket, moreover it is possible to
Avoid gasket by radiative aging.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
