Abstract
The utility model relates to a double-spiral chamber air inlet channel of a diesel engine, which belongs to the field of diesel engine parts and determines the air valve arrangement mode according to an air cylinder cover skeleton model. Two spiral air channels are arranged on a cylinder cover, respectively provided with a main spiral air inlet and an auxiliary spiral air inlet on the side surface of the cylinder cover and respectively enter an air cylinder from air inlet throats of the cylinder cover. The double-spiral chamber air inlet channel has advanced performance, reasonable structure, optimized shape and short development period, can rapidly accomplish development operation and completely meet the requirements of the modern light diesel engine on the air inlet system.
Description
Technical field
The utility model belongs to the parts and components of diesel engine field.
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 utility model is determined the diesel engine double helix chamber intake duct of valve arrangement according to the cylinder head skeleton pattern.
The utility model has two spiral air flues on cylinder cap, two spiral air flues have main spirally inlet air mouth and secondary spirally inlet air mouth respectively in the side of cylinder cap, and two spiral air flues enter cylinder interior at cylinder cap air inlet aditus laryngis respectively.
The utility model is advanced in performance, rational in infrastructure, Shape optimization, construction cycle short, can finish development fast, satisfies the requirement of modern light diesel engine to gas handling system fully.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model has 4, two spiral air flues 4 of two spiral air flues to have 1, two spiral air flue 4 of main spirally inlet air mouth 2 and secondary spirally inlet air mouth to enter cylinder interior at cylinder cap 3 air inlet aditus laryngis 5 respectively respectively in the side of cylinder cap 3 on cylinder cap 3.
Determine the inlet characteristic development goal according to the requirement of combustion system, determine the valve arrangement according to the cylinder head skeleton pattern then.Because the utility model is to be applied on 4 valve diesel, so intake duct adopts 2 valve schemes, and according to the requirement of air cylinder head structure intensity, inlet and exhaust valve has adopted and has been arranged in parallel.Because being 4 cylinder integral type cylinder head, arranges this type, structural strength, high and low cycle fatigue are very strict, as adopt single air-intake type intake duct will cause one-sided stress to concentrate, have a strong impact on the requirement of high and low cycle fatigue, and single air-intake type intake duct also is unfavorable for the air movement in rationalization's cylinder.For this reason, we have adopted the double-screw type intake duct, and two helical intakes cooperate organizes air inlet.This intake duct arrangement not only makes air cylinder head structure more rationally (greatly having reduced stress concentrates), and is easy to realize finishing fast the adjustment of interior air mass flow of cylinder and air spin intensity.
The utility model is realized by the following method: after having determined valve arrangement and position size, the utilization 3 d modeling software carries out three-dimensional intake duct model design.The draft angle and the joint line that at first think about each intake duct before the design beginning are designed two independent spiral inlet ducts then.After the design of intake duct threedimensional model is finished, design the last lower body (being convenient to turn over the system resin mould) of intake duct blowing box again; Use CNC processing technology (CAM) and process lower body on the blowing box.Last lower body is assembled together and turns over system resin intake duct sample post.Adjusting on Steady Flow Test Rig on this basis then and revising the intake duct shape makes its air inlet situation satisfy the requirement of combustion system.Turn over then and make resin intake duct sample post, resin intake duct sample post shapes at this moment is the shape that finally is applied on the cylinder head.The reverse generation three-dimensional data model of intake duct sample post that application laser camera technique will finally be finished is used for cylinder head model checking, cylinder head jacket design and intake duct trial-production mould development.
