Description

The internal-combustion engine of liquid cooling
The present invention relates to a kind of internal-combustion engine of liquid cooling, this internal-combustion engine comprises at least one cylinder block and multiple cylinder with coolant jacket, wherein, coolant jacket has towards the bottom of crankcase with towards the top of cylinder head sealing plane, and bottom has as the wave mode profile seen at the side view of cylinder block, wherein, between the bottom at coolant jacket recording along cylinder-bore axis direction in the region of at least one the first motor Transverse plane that comprises cylinder-bore axis and top first distance is larger than the second distance in the region of at least one the second motor Transverse plane between two adjacent cylinder.
U. S. Patent the 5th, has described for 080, No. 049A a kind ofly for having the cylinder block of internal-combustion engine of some cylinders, and wherein, each cylinder cover institute that is cooled surrounds.Coolant jacket has wave mode profile in a longitudinal side of cylinder block, little in the region of the first transverse engine plane that wherein, the bottom of coolant jacket is comprising cylinder-bore axis from the distance of cylinder head sealing plane in the region internal ratio of the motor Transverse plane that comprises cylinder head screw axis.
Also by the internal-combustion engine of the liquid cooling of the known a kind of coolant jacket with analogous shape of AT504 983B1.
JP2011-106 398A1 discloses a kind of cooling structure for internal-combustion engine, wherein, cold get to be enclosed within the first and second motor Transverse planes there is uniform height.Distance between bottom and the top of coolant jacket is only little in other region in territory, end face lateral areas internal ratio.
WO95/21323A1 discloses a kind of cooling system of the two-stroke internal-combustion engine with the some cylinders that surrounded by coolant jacket.The bottom of coolant jacket is provided with wave mode profile, and in the region of the motor Transverse plane between two cylinders via U-shaped tributary circuit and vertical passage portion section and the coolant collecting device of flow below being communicated to.
Also become known for the coolant jacket of crankcase by CN2 751 151Y, this coolant jacket bottom as formed with wave mode pattern as seen in side view.Cold get cover little in the region of the second motor Transverse plane of the first motor Transverse plane internal ratio between two cylinders that comprises cylinder-bore axis apart from the distance of cylinder head sealing plane.Thus, the cooling of region to height heat load will be improved.
Particularly in the region of outside cylinder, there is relatively large cylinder deformation.
Therefore the distortion that, the object of the invention is to avoid these shortcomings and reduce outside cylinder.
This realizes in the following way according to the present invention: the cold cover of getting has three kinds of different heights, wherein, at least one end region between cold bottom of getting cover and top, at coolant jacket-less than the distance in the region of the second motor Transverse plane between two adjacent cylinder compared with the distance of the 3rd in the region of the good motor longitudinal plane extending at cylinder-bore axis.
If at least one end region, the distance between bottom and top reach distance between bottom and top approximately 90%, better for approximately between 50% to 70%, can realize particularly preferred result.
Due in the end region of coolant jacket, along the contraction of cylinder-bore axis direction, the stationary temperature that can reduce on the one hand cooling in this region and realize thus cylinder block distributes, and the structure of cylinder block can be firmer on the other hand, and can significantly reduce thus distortion.
, explain in more detail with reference to the accompanying drawings the present invention below, wherein:
Fig. 1 illustrates according to the coolant jacket of the cylinder block of the first embodiment of the present invention with side view;
Fig. 2 illustrates coolant jacket with plan view;
Fig. 3 illustrates coolant jacket with front view;
Fig. 4 illustrates the coolant jacket of cylinder block according to a second embodiment of the present invention with side view;
Fig. 5 is illustrated in known cylinder seat and is out of shape according to the quadravalence of outside cylinder in cylinder block of the present invention.
Fig. 1 to 3 illustrates the coolant jacket 1 of the cylinder block (not being shown in further detail) of the internal-combustion engine with four cylinders 9, and described coolant jacket 1 surrounds cylinder liner.Visible in side view as shown in FIG. 1, the bottom 2 of coolant jacket 1 is shaped with wave mode pattern so that bottom 2 from the height H of cylinder head plane 3 as along cylinder block longitudinally as shown in increase and reduce.Specifically, the distance H in the region of the first motor Transverse plane 5 that comprises cylinder-bore axis 4 is for example, than the distance in region that extend between two cylinders, the second motor Transverse plane 7 of extending by the axis 6 of the cylinder head screw hole for cylinder head screw larger.
Between the bottom 2 of coolant jacket 1 and top 3, in the end region 8 of outside cylinder 9-specifically extend the distance H in the region of motor longitudinal plane 13 of (span occupies) at cylinder-bore axis 4 2less than the distance in the region of the second motor Transverse plane 7 between two cylinders 9.The distance H between top 3 and bottom 2 in the end region 8 of face side 1a, 1b 2be in the region of the first motor Transverse plane 5 top 3 and bottom 2 between ultimate range H approximately 50% to 80%.
Fig. 4 and Fig. 6 illustrate the coolant jacket 1 for three cylinder IC engines, wherein, in Fig. 4 for compared with profile as suggested in the present invention, use dotted line 10 that the profile of known coolant jacket is shown.By will be apart from from H 2' be reduced to H 2realize the remarkable improvement that carrys out the quadravalence cylinder deformation in the region of mark with the reference character 11 in the deformation pattern shown in Fig. 5.Former deformable contour represents with the dotted line 12 ' in the deformation pattern of Fig. 5, and has the distance H of reducing 2deformable contour represent with reference character 12.
Can be by reducing the distance H of the end region 8 adjacent with outside cylinder between the top 3 of coolant jacket 1 and bottom 2, that be arranged in coolant jacket 1 2increase the rigidity of cylinder block.
