Abstract
The utility model discloses a kind of cylinder cap with EGR channel, including cylinder cap, the top of the cylinder cap is provided with inlet manifold, the inlet manifold is connected with EGR assemblies, the EGR assemblies side is provided with EGR intake elbows, the bottom of the cylinder cap is provided with exhaust manifold, the side of described cylinder cap offers an EGR channel, the inside of the EGR channel is provided with cooler for recycled exhaust gas core, and the top of the EGR channel is connected to the EGR intake elbows, the bottom of EGR channel is connected to the exhaust manifold by EGR exhaust bend pipe.The utility model assembles cooler for recycled exhaust gas core by casting processing EGR channel in cylinder cap in EGR channel, reduces the associated pipe in original system and external cooler for recycled exhaust gas, makes engine structure more succinct, and reduces engine cost.
Description
Technical field
The cylinder cap design field of engine is the utility model is related to, refers specifically to a kind of cylinder with EGR channel
Lid.
Background technology
At present, in order to reach emission request, engine is equipped with egr system mostly at present（Waste gas recycles（Exhaust
Gas Recirculation））, its primary structure is waste gas gas path device and cooling water channel device, and waste gas gas path device is by being vented
Manifold draws waste gas all the way, enters inlet manifold by cooler for recycled exhaust gas, associated pipe and EGR assemblies；Cooling water channel device be from
Thermostat draws water all the way, enters cooler for recycled exhaust gas by associated pipe, thermostat is returned after being cooled down to waste gas.Due to
The system parts are loaded on external engine, make external engine complicated, and space hold is big, parts installation, arrangement
It is difficult.
Utility model content
The utility model is in order to solve the above-mentioned deficiency of prior art, it is proposed that a kind of cylinder cap with EGR channel.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：A kind of cylinder with EGR channel
Lid, including cylinder cap, the top of the cylinder cap are provided with inlet manifold, and the inlet manifold is connected with EGR assemblies, the EGR assemblies
Side is provided with EGR intake elbows, and the bottom of the cylinder cap is provided with exhaust manifold, and the side of described cylinder cap offers one
EGR channel, the inside of the EGR channel is provided with cooler for recycled exhaust gas core, and the top of the EGR channel is connected to the EGR air inlets
Bend pipe, the bottom of EGR channel are connected to the exhaust manifold by EGR exhaust bend pipe.
Further, the side of described cylinder cap is additionally provided with assembly of thermostat, and the EGR channel is communicated in the thermostat
The cold water water route of assembly.
Engine cylinder cover of the present utility model is one EGR channel of casting processing on cylinder cap, can be filled in EGR channel
With cooler for recycled exhaust gas core, waste gas is cooled down by the water in cylinder cap thermostat, eliminates the phase of the disengaging cooling water channel of traditional cylinder cover
Part is closed, while waste gas is directly entered in cooler core, led to after cooling by passing through EGR exhaust bend pipe after exhaust manifold again
Cross EGR intake elbows and enter EGR assemblies, eliminate the parts such as former external cooler for recycled exhaust gas, reduce the parts such as former cooler for recycled exhaust gas
Installing space.
The beneficial effects of the utility model are：The utility model processes EGR channel by being cast in cylinder cap, and
Cooler for recycled exhaust gas core is assembled in EGR channel, reduces the associated pipe in original system and external cooler for recycled exhaust gas, makes engine knot
Structure is more succinct, and reduces engine cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model proposes the cylinder cap with EGR channel, including cylinder cap 1, the top of cylinder cap 1 is provided with
Inlet manifold 5, inlet manifold 5 are connected with EGR assemblies 4, and the side of EGR assemblies 4 is provided with EGR intake elbows 3, the bottom of cylinder cap 1
Provided with exhaust manifold 7, the side of cylinder cap 1 offers an EGR channel 8, and the inside of EGR channel 8 is provided with cooler for recycled exhaust gas core 2,
And the top of the EGR channel 8 is connected to EGR intake elbows 3, the bottom of EGR channel 8 is connected to exhaust by EGR exhaust bend pipe 9
Manifold 7.The side of cylinder cap 1 is additionally provided with assembly of thermostat 6, and EGR channel 8 is communicated in the cold water water route of assembly of thermostat 6.
Engine cylinder cover of the present utility model is one EGR channel of casting processing on cylinder cap, can be filled in EGR channel
With cooler for recycled exhaust gas core, waste gas is cooled down by the water in cylinder cap thermostat, eliminates the phase of the disengaging cooling water channel of traditional cylinder cover
Part is closed, while waste gas is directly entered in cooler core, led to after cooling by passing through EGR exhaust bend pipe after exhaust manifold again
Cross EGR intake elbows and enter EGR assemblies, eliminate the parts such as former external cooler for recycled exhaust gas, reduce the parts such as former cooler for recycled exhaust gas
Installing space.
Above-described embodiment only expresses several embodiments of the present utility model, and its description is more specific and detailed, but simultaneously
Can not be therefore understands that being the limitation to the utility model patent scope.It should be pointed out that the ordinary skill people for this area
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With new protection domain.Therefore, the utility model patent and protection domain should be defined by appended claims.
