The air inlet structure is provided with an air inlet, which is positioned at the side of the cylinder head, the air inlet structure includes two air valves arranged on the cylinder head, an vertical air inlet pipe and a spiral air inlet pipe, and the two air valves respectively are connected with the vertical air inlet pipe and spiral air inlet pipe, which is provided with an air inlet conditioning, which is connected with an electric control system, which is connected with the temperature sensor arranged inside the cylinder of the diesel engine. The utility model can improve the power of the diesel engine, achieving automatic control of the air inlet amount and eddy current strength, and reducing fuel consumption and smoke emission, and can be widely used in the manufacturing industry with multi-cylinder multi-valve diesel engine cylinder head.
Description
Technical field
The utility model relates to a kind of multi-cylinder diesel engine air flue, especially has four valve four-cylinder diesel engine air flues of twin-inlet.
Background technique
Existing multi-cylinder diesel engine intake duct is divided into spiral or tangential.Defectives such as domestic diesel engine generally adopts single intake duct at present, and single intake duct diesel engine exists power low, and oil consumption is big, and smoke intensity is big.Four valve four-cylinder diesel engines are because air inflow increases, and therefore, single intake duct can not meet the demands.Though and employing double air passage diesel engine has increased air inflow, can not the parameter of air flue eddy current be controlled, therefore can not further improve diesel engine power, reduce oil consumption, reduce smoke intensity.
Summary of the invention
The technical problems to be solved in the utility model is to overcome deficiency of the prior art, a kind of power that can improve diesel engine is provided, reduce oil consumption, reduce smoke intensity, meet the toxic emission requirement and can prevent the four valve four-cylinder diesel engine air flues that four-valve cylinder head cracks.
For solving the problems of the technologies described above, the utility model provides a kind of four valve four-cylinder diesel engine air flues, comprise cylinder head and the intake duct structure that is arranged on the described cylinder head, described intake duct structure is provided with the air inlet inlet, described air inlet inlet is arranged on the side of cylinder head, described intake duct structure comprises and is arranged on two intake valves that are provided with on the cylinder head, and a tangential intake duct and a spiral inlet duct, two intake valves are connecting tangential inlet duct and spiral inlet duct respectively, in described spiral inlet duct, be provided with an air inlet regulating device, this air inlet regulating device is connected with an automatical control system, this automatical control system be arranged on that temperature transducer is connected in the cylinder of diesel engine.
Wherein, described temperature transducer is collected the data in the cylinder of diesel engine, this temperature transducer is an electrical signal with data conversion, described automatical control system receives described electrical signal, and sending control signal to described air inlet regulating device, described air inlet regulating device receives described control signal and regulates air inflow.
As a kind of improvement of the present utility model, described tangential inlet duct and spiral inlet duct comprise split air inlet guide channel, described air inlet guide channel is communicated with the air inlet inlet, and near intake duct is a spiral inlet duct apart from the air inlet entry position, and intake duct far away is a tangential inlet duct.The part of the cylinder head between described two intake valves is the bridge of the nose structure of " U " font.
Because adopt above technological scheme, the utility model compared with prior art has following benefit:
1. raising diesel engine power;
2. realize the automatic control of air inflow and strength of vortex;
3. reduce oil consumption, reduce emission smoke intensity.
