Abstract
A water jacket structure of a turbo supercharged engine cylinder body of a split type camshaft cover comprises cylinder body water jackets, a centrifugal water pump, water inlets of the water jackets and a water bridge leading to a cylinder cover water jacket. The water jacket structure of the turbo supercharged engine cylinder body is characterized in that according to the cylinder body water jackets, four circular cylinder body water jackets connected in series are symmetrically arranged between the cylinder body and a cylinder sleeve, kidney-shaped water channels leading to a cylinder cover are arranged on the upper portions of the circular cylinder body water jackets, the water bridge leading to the cylinder cover water jacket is arranged between the four circular cylinder body water jackets connected in series, and a water outlet of the centrifugal water pump is communicated with the water inlets of the water jackets. The water jacket structure of the turbo supercharged engine cylinder body has the advantages that the water jackets cover the upper region of a combustor, the contact area of the water jackets and the outer wall of the combustor is large, heat can be more effectively exchanged, the water outlet is big in size and water flow is smooth, quantity of flow is large, and exchange is rapid. In a manufacturing process, molding sand is relatively easy to clear, and cleanliness is ensured.
Description
Technical field
The utility model belongs to the motor vehicle gasoline technical field of engines, specifically a kind of motor car engine turbosupercharged engine block jacket structure.
Background technique
During motor car engine work, the component temperature that the heat that high-temperature fuel gas and friction generate can make raises, thereby causes distortion, reduces its mechanical strength and rigidity, and destroys lubricant film; Enter the air (or inflammable mixture) of cylinder owing to strongly be heated, specific volume increases, so that the actual gas weight that enters in the cylinder reduces.The high temperature of motor can also make inflammable mixture produce pre-ignition, causes the motor malfunction, and these all can make engine performance descend.When overheat condition is serious, also may make damage of components.Therefore, must suitably be cooled off motor.
The block jacket of motor car engine is being undertaken the magnificent mission of cooling off cylinder body, block jacket reasonable in design can guarantee that motor works under optimum state of temperature, generally speaking, cooling water temperature in the water jacket is best at 80 ~ 95 ℃, water temperature over-high, can damage component, destroy lubricant film, can cause complete machine to scrap when serious; Water temperature is too low, heat can be dispersed in the atmosphere too much, this just must loss part fuel, the fuel oil consumption is increased, and machine oil viscosity increased when low temperature, increased the frictional resistance of part movement, output power is reduced.
Summary of the invention
The purpose of this utility model provides a kind of increase and enters the water yield, the turbosupercharged engine block jacket structure of balanced cooling air cylinder body.
The purpose of this utility model is to realize like this, it includes block jacket, centrifugal water pump, water jacket water intake, lead to the water bridge of cylinder cover water jacket, it is characterized in that: block jacket is the circular cylinder body water jacket of symmetrically arranged four series connection between cylinder block and cylinder liner; Also be provided with the kidney-shaped water channel that leads to cylinder cap on the top of circular cylinder body water jacket, between the circular cylinder body water jacket of four series connection, also be provided with the water bridge that leads to cylinder cover water jacket; The pump outlet of centrifugal water pump is connected with the water jacket water intake.
Described kidney-shaped water channel quantity is corresponding 20 kidney-shaped water channels that arrange.
For having reduced the flow resistance of cooling water, the water jacket water intake is the level and smooth streamline structure of helical.
The utlity model has following advantage:
1, cooling water enters the water jacket water inlet by centrifugal water pump, because this place is the level and smooth streamline structure of helical, reduced the flow resistance of cooling water, make cooling water can pass through exit of pump, the more unobstructed water jacket that enters has guaranteed that motor works under optimum temperature.
2, the water jacket in the cylinder block left side is designed with the acclivitous water bridge in three roads, leads to cylinder cover water jacket, makes Cooling of Cylinder Head more even.
3, increased the cooling water flow that leads to cylinder cap.
4, this novel also have simple and reasonable, long service life, the advantage such as safe and reliable.
Description of drawings
Fig. 1 is the stereochemical structure simplified schematic diagram of the utility model block jacket;
Fig. 2 is the state simplified schematic diagram of the utility model on engine cylinder;
Fig. 3 is the state simplified schematic diagram of the utility model on the engine cylinder section;
Fig. 4 is the simplified schematic diagram that concerns of the utility model and cylinder head water jacket.
The symbol description of accompanying drawing major component: 1-pump outlet, 2-lead to the water bridge of cylinder cover water jacket, 3-kidney-shaped water channel, and the 4-block jacket,
5-water jacket water intake, the 6-centrifugal water pump.
The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example only is the utility model example wherein; do not represent the right protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claims.
Embodiment
Example 1
Shown in Fig. 1～4, the utility model is four cylinder engine, and 4 among the figure is block jacket, the circular cylinder body water jacket that this block jacket 4 is symmetrically arranged four series connection between cylinder block and cylinder liner; Also be provided with the kidney-shaped water channel 3 that leads to cylinder cap on the top of circular cylinder body water jacket 4, between the circular cylinder body water jacket 4 of four series connection, also be provided with the water bridge 2 that leads to cylinder cover water jacket; The pump outlet 1 of centrifugal water pump 6 is connected with water jacket water intake 5.
The block jacket working principle: by shown in Figure 1, cooling water is from the pump outlet 1 of centrifugal water pump 6, the water jacket water intake 5 of flowing through, enter block jacket 4, carry out cool cycles, enter cylinder cover water jacket via water channel 2 and 3 again, thereby finished the cooling procedure of cylinder block.
