Abstract
The utility model relates to a single cylinder one-cover double-layer water jacket and is characterized in that: an independent cylinder cover is arranged on each cylinder of an engine, the water jacket of the cylinder cover is separated into an upper layer and a lower layer; a water inlet is arranged on the lower layer of the water jacket; a water outlet is arrange on the upper layer of the water jacket; a through hole is arranged between the upper layer and the lower layer of the water jacket; the water inlet and the water outlet are connected to different water channels of a cylinder body. Through combination of single cylinder one cover and double-layer water jacket, the distributing conditions of stress and cooling flow of the cylinder cover during the working process are greatly improved, and the cylinder cover is made to have quite high reliability on low-cycle and high-cycle fatigue problem.
Description
Technical field:
A kind of single-cylinder one-cap double-layer water sleeve that the utility model relates to is applied on the CA6DN1 motor.
Background technique:
At present, in multicylinder engine, cylinder head generally adopts the layout of individual layer integral water jacket.From the aspect of performance of cylinder head, the cooling water flow of cylinder head individual layer water jacket distributes and to be difficult to the layout that reaches desirable, and is limited to the cooling effect of cylinder head.In addition, in the motor practical work process, situations such as individual layer water jacket cylinder head stress deformation, heat load, low cycle fatigue are also undesirable, bring great difficulty to design work.
Summary of the invention:
The purpose of this utility model is to provide a kind of single-cylinder one-cap double-layer water sleeve, in single-cylinder one-cap formula motor, cylinder cap is designed to double-layer water jacket, single-cylinder one-cap combines with the layering water jacket, cylinder head stressing conditions in the course of the work is improved, and cylinder head has very high reliability on low week and intermediate and high cycle fatigue problems.
The technical solution of the utility model is achieved in that single-cylinder one-cap double-layer water sleeve, it is characterized in that: on each cylinder of motor independently cylinder head is installed, cylinder head jacket is separated into two-layer up and down, lower layer of water puts and is provided with water inlet, upper water puts and is provided with water outlet, be provided with through hole between the water jacket upper and lower layers, intake-outlet is connected on the different water channels of cylinder block.
Good effect of the present utility model is that the design of layering water jacket is divided into double-deck control with the cylinder head cooling water flow, this cooling requires high zone to be isolated in the lower floor of double-layer water jacket in design near the air flue bridge of the nose district, can make herein that current reach rational designing requirement, thereby make cylinder head reach optimum cooling effect.
Owing to be provided with dividing plate between double-layer water jacket, the strength and stiffness that this has increased cylinder cap greatly are greatly improved its reliability.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 moves towards schematic representation for double-layer water jacket current of the present utility model;
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described: single-cylinder one-cap double-layer water sleeve as shown in Figure 1, it is characterized in that: independently cylinder head 1 is installed on each cylinder of motor, cylinder head 1 cover is separated into two-layer up and down, lower floor's water jacket 2 is provided with water inlet 3, upper strata water jacket 4 is provided with water outlet 5, be provided with through hole 6 between the water jacket upper and lower layers, intake-outlet is connected on the different water channels of cylinder block.
Adopt double-layer water jacket in the In-line multi-cylinder engine cylinder head, can improve the mechanical propertys such as rigidity, intensity of part.The current control of cylinder cap double-layer water jacket more helps the cylinder head current and distributes.
As shown in Figure 2, current at first pass through the beneath layer of cylinder head water jacket, significant points such as positive cooling airway bridge of the nose district, and the through hole between the water jacket upper and lower layers flows into the upper strata water jacket then, gets back to cylinder block by water outlet at last, cools off other parts.Cooling water at first enters cylinder head, it is cooled off, and then get back to cylinder block, cools off other parts, and so greatly the cylinder head that makes high heat load of degree is fully cooled off, and it is more reasonable to make that current distribute.
