Abstract
The invention relates to a double-intake passage, which is characterized in that four valves including air inlet and exhaust valves are distributed in rhombus while the air inlet passages are respectively a helical air inlet passage and a tangential air inlet passage. The helical air inlet passage clockwise organizes the airflow motion in a cylinder and the tangential air inlet passage is positioned at the left side of the helical air inlet passage. The helical air inlet passage independently organizes the eddy motion in the cylinder. The tangential air inlet passage is utilized to ensure more air inflow and integrated with an air inlet tank as a whole in the entrances to the two air inlet passages. The double-intake passage of the invention has advanced performance, reasonable structure, optimized shape and short development period and the development can be quickly completed, thus completely meeting the requirements of a modern heavy-duty diesel engine for an air inlet system.
Description
Technical field:
The present invention relates to a kind of double-air-intake type intake duct, be applied on 4 valve diesel.
Background technique:
At present, in motor, guarantee air inflow enough in the cylinder and reasonably organize air movement most important engine performance.Intake duct is arranged in the cylinder head, and reasonably the air flue shape of intake duct layout and optimization not only has material impact to air inlet in the cylinder, but also the layout of air cylinder head structure intensity, heat transfer and cylinder head inner water sleeve is all had material impact.Reasonably intake duct layout and shape have not only guaranteed the requirement of combustion system to air inlet, and can make the structural configuration of cylinder head more reasonable, thereby have guaranteed cylinder head extremely requirement of harshness aspect intensity and heat transfer.
Summary of the invention:
The object of the present invention is to provide a kind of double-air-intake type intake duct, it is divided into a helical intake with intake duct, a tangential air flue, and two air flues are organized air inlet separately; The intake duct arrangement not only makes air cylinder head structure more rationally promptly greatly reduce stress and concentrates, and realizes finishing fast the adjustment of interior air mass flow of cylinder and air spin intensity.
Technological scheme of the present invention is achieved in that double-air-intake type intake duct, it is characterized in that: totally 4 valve diamondwises of intake and exhaust distribute, and intake duct is respectively one is spiral inlet duct, one is tangential inlet duct, spiral inlet duct is for organizing air motion in the cylinder clockwise, tangential inlet duct is positioned at spiral inlet duct left side, the ingress of two intake ducts and the inlet box individual integral body that permeates.
Good effect of the present invention is: its air-flow that has not only reduced between two intake ducts is interfered, and the requirement of the strength of vortex in can realizing in a big way.In the ingress of two an intake ducts and inlet box integral body that permeates, simplified being connected between intake duct and the suction tude, and advanced in performance, rational in infrastructure, Shape optimization, construction cycle are short, can finish development fast, satisfy of the requirement of modern heavy-duty diesel engine fully gas handling system.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Embodiment:
The present invention will be further described below in conjunction with accompanying drawing: double-air-intake type intake duct, it is characterized in that: totally 4 valve diamondwises of intake and exhaust distribute, and intake duct is respectively one is spiral inlet duct 1, one is tangential inlet duct 2, spiral inlet duct 1 is for organizing air motion in the cylinder clockwise, and tangential inlet duct 2 is positioned at spiral inlet duct 1 left side.Spiral inlet duct 1 is organized eddy motion in the cylinder separately, utilizes tangential inlet duct 2 to guarantee more air inflow, in the ingress and the inlet box 3 of two intake ducts individual integral body that permeates.
The intake duct working procedure is: in engine working process, air enters into inlet box 3 by air-strainer, enters in the cylinder by spiral inlet duct 1 and tangential inlet duct 2 respectively then.Because the influence of spiral inlet duct 1 structure shape, the air that enters in the cylinder by spiral inlet duct 1 turns clockwise around cylinder axis, thereby guarantee that cylinder combustion oil and air mixing get more even, and enter air in the cylinder except further enhancing oil gas mixed effect by tangential inlet duct 2, and can also increase and enter air quantity, guarantee that fuel oil gets more abundant burning.
