Abstract
The invention discloses a cooling water jacket structure for cooling an engine, comprising a water jacket (2) of a cylinder body and a water jacket (1) of a cylinder cover. Cooling water enters from the cylinder body and then enters in the water jacket (1) of the cylinder cover through the water jacket (2) of the cylinder body; then, the cooling water enters in the water jacket (2) of the cylinderbody from the water jacket (1) of the cylinder cover and finally flows out of the cylinder body. Since the circulation of a cooling water flow from the water jacket of the cylinder cover to the waterjacket of the cylinder body is added, engine heat absorbed by the cooling water is more and more and the rise of the water temperature of the engine is quicker. The purpose of quickly heating the engine is achieved, which is beneficial to improving discharge performance after the engine is started.
Description
Technical field
The present invention relates to the cooling jacket structure of water-cooled automobile motor, relate in particular to the engine cooling water jacket structure of forming by cylinder block, cylinder head.
Background technique
The engine cooling water jacket structure is made up of block jacket and cylinder head jacket, traditional current are organized generally and are: cooling water enters from cylinder block one side, after block jacket, pass in the water jacket that head gasket enters into cylinder head, flow out from cylinder head one end then, be that in-engine water cycle is to flow to cylinder head from cylinder block, the import and export of cooling water lay respectively on the cylinder block and head.Cooling water also is after absorbing the heat of cylinder block earlier, absorbs the heat of cylinder head again, flows out from cylinder head at last.The circulation of this cooling water does not make full use of the burning liberated heat of motor, so the water temperature of motor rises slowly, is unfavorable for improving the emission performance after the engine start.
Summary of the invention
For the heat that effectively utilizes engine combustion to discharge, make Rapid Thermal machine after the engine start, thereby more help improving the emission performance after the engine start, the invention provides a kind of new engine cooling water jacket structure and current organizational form.
The invention provides a kind of engine cooling water jacket structure, comprise block jacket and cylinder head jacket, cooling water enters from cylinder block, enters into after block jacket in the cylinder head jacket, enter into again in the block jacket from cylinder head jacket then, flow out from cylinder block at last; Block jacket is provided with cooling water water inlet and cooling water outlet; Also be provided with two baffle plates on the block jacket, block jacket is separated into two-part, cooling water water inlet and cooling water outlet are separately positioned on these two-part; The block jacket bottom is designed to wavy shaped configuration along water (flow) direction, and the trough of this wavy shaped configuration is positioned at single cylinder block neutral position, the neutral position of crest between two cylinder block.
The present invention also provides a kind of motor, and motor comprises aforesaid engine cooling water jacket structure.
The present invention also provides a kind of cooling means of motor, and cooling water enters from cylinder block, enters into after cylinder block in the cylinder head, enters in the cylinder block from cylinder head then again, flows out from cylinder block at last.
The present invention reorganizes the water cycle of engine cooling water, makes it flow to cylinder head from cylinder block earlier, flows back to cylinder block from cylinder head then, and cooling water is all from the cylinder block inflow and outflow.Concrete flow direction is: cooling water enters from the block jacket inlet earlier, be up to the cylinder head jacket homonymy from block jacket one side, after walking around the head combustion chamber water route then, flow back in the block jacket homonymy from the cylinder head opposite side again, go out from this effluent of block jacket at last.Simultaneously in order to prevent that cooling water from only circulating in block jacket, and do not flow in the cylinder head jacket, therefore being provided with two baffle plates in block jacket, block jacket is separated into two-part, is that block jacket and cylinder head jacket are formed a circulation waterway by this structure.For better controlled water flow flows, the block jacket bottom design has wavy shaped configuration in addition, and trough is positioned at single cylinder block zone line, the neutral position of crest between two cylinder block.
The present invention turns back to this circulation of block jacket owing to increased cooling water flow from cylinder head jacket, the motor heat that cooling water is absorbed is more sufficient, therefore the water temperature of motor rises rapider, so just can reach the purpose of motor Rapid Thermal machine, thereby more help improving the emission performance after the engine start.
Description of drawings
Fig. 1 is that cylinder block of the present invention, cylinder head current are organized schematic representation.
Fig. 2 is a block jacket side view of the present invention.
Fig. 3 is a block jacket plan view of the present invention.
Embodiment
With reference to Fig. 1, the current tissue of jacket structure for water of the present invention is: cooling water enters into block jacket 2 from block jacket 2 water inlets 4 on diagram right side, side from block jacket 2 is up to phase the same side that cylinder head jacket 1 links to each other then, after walking around the head combustion chamber water route, be back to block jacket 2 homonymies from cylinder head jacket 1 opposite side, flow out from water outlet 3 at last.
With reference to Fig. 2, block jacket 2 bottoms are designed to wavy shaped configuration 5 along water (flow) direction, and trough is positioned at single cylinder block neutral position, the neutral position of crest between two cylinder block, thus more help cooling-water flow.
With reference to Fig. 3, block jacket 2 is by two baffle plate 6 separated into two parts, and cooling water flows into from water inlet 4, and the water outlet 3 from opposite side flows out then.Cooling water can be only flows in block jacket 2 and does not enter cylinder head jacket 1 like this, among the figure as can be seen the import and export position of cooling water all be positioned on the block jacket 2.
