DESCRIPTION OF EMBODIMENTS
[0023] Embodiments of this application are described in detail below. The embodiments described
with reference to the accompanying drawings are examples.
[0024] The following describes a cylinder body 1 according to an embodiment of this application
with reference to FIG. 1 to FIG. 4.
[0025] As shown in FIG. 1, the cylinder body 1 according to this embodiment of this application
includes a cylinder body water jacket 20. The cylinder body 1 may mainly provide a
mounting and fastening function. The cylinder body water jacket 20 refers to space
between an inner housing and an outer housing of the cylinder body 1. Coolant may
circulate in the water jacket to take away heat formed by the cylinder body 1.
[0026] As shown in FIG. 1, the cylinder body 1 further includes a plurality of cylinder
barrels 11. The cylinder barrel 11 defines a space for movement of a piston, the piston
may smoothly slide back and forth in the cylinder barrel 11, and the cylinder barrel
11 is also a place in which fuel and oxygen fully mix and burn to generate energy.
Energy generated by fuel combustion pushes the piston and transfers force to a wheel,
so that the wheel rotates to drive a vehicle to move.
[0027] As shown in FIG. 1 and FIG. 3, the cylinder body water jacket 20 includes a cylinder
barrel water jacket 21 and a secondary water jacket 22. The cylinder body 1 is provided
with a liquid inlet 12, the cylinder barrel water jacket 21 and the secondary water
jacket 22 are separately connected to the liquid inlet 12, the cylinder barrel water
jacket 21 is disposed at the plurality of cylinder barrels 11, and the secondary water
jacket 22 is in communication with a cylinder head water jacket 29. To be specific,
coolant may enter the cylinder body 1 from the liquid inlet 12. A part of the coolant
may flow into the plurality of cylinder barrels 11 through the cylinder barrel water
jacket 21, to cool and lower temperatures of the plurality of cylinder barrels 11.
The coolant obtained after cooling the plurality of cylinder barrels 11 may be discharged
from the cylinder barrel water jacket 21. The other part of the coolant may enter
the secondary water jacket 22. The secondary water jacket 22 provides a communication
function, so that the coolant can enter the cylinder head water jacket 29 through
the secondary water jacket 22, to cool and lower a temperature of a cylinder head.
[0028] In this way, the secondary water jacket 22 is provided, so that coolant can directly
enter the cylinder head water jacket 29 through the secondary water jacket 22. In
this way, the coolant can independently flow through the cylinder barrel water jacket
21 and the cylinder head water jacket 29, and the coolant does not need to pass through
the cylinder barrel water jacket 21 before flowing into the cylinder head water jacket
29, thereby implementing allocation of coolant flow to the cylinder barrel water jacket
21 and the cylinder head water jacket 29, and improving cooling efficiency of the
cylinder body 1 and the cylinder head.
[0029] As shown in FIG. 1, the secondary water jacket 22 is disposed on a side of the cylinder
barrel water jacket 21 away from the plurality of cylinder barrels 11. In other words,
the cylinder barrel water jacket 21 may separate the secondary water jacket 22 from
the plurality of cylinder barrels 11. In this way, heat of the plurality of cylinder
barrels 11 may be emitted to the cylinder barrel water jacket 21, and an amount of
heat of the plurality of cylinder barrels 11 emitted to the secondary water jacket
22 may be reduced, to prevent heat emitted by the plurality of cylinder barrels 11
from affecting coolant in the secondary water jacket 22, thereby improving a cooling
effect of the coolant in the secondary water jacket 22 on the cylinder head.
[0030] Optionally, as shown in FIG. 1, the cylinder body 1 further includes a plurality
of first throttles 40, and the plurality of first throttles 40 are spaced apart on
the secondary water jacket 22. The first throttle 40 may provide a throttling function.
A plurality of first throttles 40 are disposed on the secondary water jacket 22, and
the plurality of first throttles 40 are spaced apart. In this way, a pressure-stabilized
water cavity may be formed when the secondary water jacket 22 discharges coolant,
so that the coolant can flow more smoothly into the cylinder head water jacket 29,
and flow of the coolant at cylinder positions of the cylinder head water jacket 29
is more uniform, thereby reducing a pressure loss.
[0031] As shown in FIG. 2, an engine includes a cylinder gasket 2, and the cylinder gasket
2 may provide a sealing function, to prevent leakage of coolant in the cylinder barrel
water jacket 21 and the secondary water jacket 22, thereby ensuring a cooling effect
of the cylinder barrel 11 and the cylinder head. The cylinder gasket 2 is provided
with at least one liquid outlet 15, the at least one liquid outlet 15 is in communication
with the secondary water jacket 22, and the at least one liquid outlet 15 is in communication
with the cylinder head water jacket 29. In other words, the coolant in the secondary
water jacket 22 may flow into the cylinder head water jacket 29 through the at least
one liquid outlet 15, to cool the cylinder head. In addition, there may be one liquid
outlet 15, so that coolant obtained after the plurality of first throttles 40 perform
throttling can form a pressure-stabilized water cavity at the liquid outlet 15. There
may alternatively be a plurality of liquid outlets 15, and the plurality of liquid
outlets 15 are disposed in correspondence with the plurality of first throttles 40.
In this way, flow of coolant at cylinder positions of the cylinder head water jacket
29 is more uniform, thereby reducing a pressure loss.
[0032] In addition, as shown in FIG. 1, the cylinder body 1 further includes a second throttle
30, and the second throttle 30 is disposed at two ends of the cylinder barrel water
jacket 21. The cylinder barrel water jacket 21 includes an intake-side water jacket
27 and an exhaust-side water jacket 28, the intake-side water jacket 27 is in communication
with the exhaust-side water jacket 28, the intake-side water jacket 27 is in communication
with the liquid inlet 12, and the second throttle 30 is disposed between the intake-side
water jacket 27 and the exhaust-side water jacket 28. The second throttle 30 may provide
a throttling function. The second throttle 30 is disposed at two ends of the cylinder
barrel water jacket 21, that is, the second throttle 30 is disposed in the cylinder
barrel water jacket 21, and the second throttle 30 is connected between the inner
housing and the outer housing of the cylinder body 1. In this way, the second throttle
30 may not only perform throttling on coolant in the cylinder barrel water jacket
21, but also improve overall structural strength of the cylinder body 1. It will be
noted that, compared with common throttling through a rubber rod, use of the second
throttle 30 reduces more costs.
[0033] The intake-side water jacket 27 is located on an intake side of the cylinder barrel
11. After entering the intake-side water jacket 27, coolant may cool the intake side
of the cylinder barrel 11. The exhaust-side water jacket 28 is located on an exhaust
side of the cylinder barrel 11. After entering the exhaust-side water jacket 28, the
coolant may cool the exhaust side of the cylinder barrel 11. The intake-side water
jacket 27 is in communication with the liquid inlet 12, so that the coolant can first
enter the intake-side water jacket 27 through the liquid inlet 12. The intake-side
water jacket 27 is in communication with the exhaust-side water jacket 28, so that
the coolant in the intake-side water jacket 27 can enter the exhaust-side water jacket
28.
[0034] The second throttle 30 is disposed between the intake-side water jacket 27 and the
exhaust-side water jacket 28, and the second throttle 30 is disposed at the two ends
of the cylinder barrel water jacket 21. To be specific, when the coolant in the intake-side
water jacket 27 is located at two ends of the cylinder barrel 11, only a small part
of the coolant enters the exhaust-side water jacket 28 because of throttling of the
second throttle 30. In this way, flowing of the coolant at the two ends of the cylinder
barrel 11 can be reduced. It will be noted that the intake-side water jacket 27 and
the exhaust-side water jacket 28 may alternatively be in communication at a junction
between two adjacent cylinder barrels 11. In this way, as much coolant in the intake-side
water jacket 27 as possible is enabled to enter the exhaust-side water jacket 28 through
the junction between the two adjacent cylinder barrels 11. Therefore, fluidity of
the coolant between the two adjacent cylinder barrels 11 can be improved, to better
perform cooling and temperature lowering between the two adjacent cylinder barrels
11, and further improve warm-up efficiency.
[0035] As shown in FIG. 1, the cylinder body 1 is provided with a cylinder head mounting
surface 13, the cylinder head mounting surface 13 is provided with a plurality of
mounting holes 14, the second throttle 30 is disposed between two adjacent mounting
holes 14, and the second throttle 30 is provided with a slot 301, and a cross section
of the slot 301 gradually increases in a direction away from the cylinder head mounting
surface 13. The cylinder head mounting surface 13 is a surface connected to the cylinder
head, and the cylinder head mounting surface 13 is provided with a plurality of mounting
holes 14, so that the cylinder head can be fastened to the cylinder body 1 through
the plurality of mounting holes 14, to form a whole with the cylinder body 1. The
second throttle 30 is disposed between two adjacent mounting holes 14, to prevent
a cylinder hole and the mounting hole 14 from being connected through the second throttle
30, thereby preventing an increase in the deformation amount of the cylinder hole.
[0036] In addition, the second throttle 30 is provided with the slot 301, and the cross
section of the slot 301 gradually increases in the direction away from the cylinder
head mounting surface 13. It will be understood that, the cross section of the slot
301 gradually increases in the direction away from the cylinder head mounting surface
13, and therefore an area in which the second throttle 30 is connected to and in contact
with the inner housing and the outer housing of the cylinder body 1 gradually decreases.
In other words, at a position close to a cylinder port, the area in which the second
throttle 30 is connected to and in contact with the inner housing and the outer housing
of the cylinder body 1 is largest. In this way, a structure of the cylinder body 1
at a position of the cylinder port is more stable and secure. When the cylinder head
is connected and mounted to the cylinder body 1, the cylinder port is not easily deformed.
In addition, this arrangement may make overall deformation of the cylinder body 1
relatively uniform and reduce impact on the cylinder body 1.
[0037] Certainly, as shown in FIG. 1, the cylinder barrel water jacket 21 disposed between
two adjacent cylinder barrels 11 defines an inter-cylinder water jacket 23, a cooling
channel 24 is formed in the inter-cylinder water jacket 23, and the cooling channel
24 connects the intake-side water jacket 27 and the exhaust-side water jacket 28.
With reference to the description above, the cylinder barrel water jacket 21 between
the two adjacent cylinder barrels 11 defines the inter-cylinder water jacket 23, and
the cooling channel 24 is formed in the inter-cylinder water jacket 23. In this way,
the coolant in the intake-side water jacket 27 can flow into the exhaust-side water
jacket 28 through the cooling channel 24, so that fluidity of the coolant between
the two adjacent cylinder barrels 11 can be improved, thereby better performing cooling
and temperature lowering between the two adjacent cylinder barrels 11.
[0038] It will be noted that, initially, a part of the coolant in the cylinder barrel water
jacket 21 flows through the intake-side water jacket 27, and a part of the coolant
enters the exhaust-side water jacket 28 through the second throttle 30. A part of
the coolant in the intake-side water jacket 27 flows into the exhaust-side water jacket
28 through the cooling channel 24, and a part of the coolant is discharged from the
liquid outlet 15 of the cylinder barrel water jacket 21. A part of the coolant in
the exhaust-side water jacket 28 flows from a water intake of a turbocharger to the
turbocharger, and a part of the coolant is also discharged from the liquid outlet
15 of the cylinder barrel water jacket 21.
[0039] Specifically, as shown in FIG. 4, the cooling channel 24 includes a first cooling
channel 25 and a second cooling channel 26, the first cooling channel 25 is in communication
with the second cooling channel 26, and both the first cooling channel 25 and the
second cooling channel 26 are disposed obliquely. To be specific, a part of the coolant
in the intake-side water jacket 27 may enter the exhaust-side water jacket 28 through
the first cooling channel 25 and the second cooling channel 26. In addition, both
the first cooling channel 25 and the second cooling channel 26 are disposed obliquely,
which helps process and dispose the first cooling channel 25 and the second cooling
channel 26, and may increase lengths of the first cooling channel 25 and the second
cooling channel 26, thereby increasing a flow range of the coolant between two adjacent
cylinder barrels 11, and improving an effect of performing cooling and temperature
lowering between two adjacent cylinder barrels 11 by the coolant.
[0040] In addition, as shown in FIG. 4, a junction between the first cooling channel 25
and the second cooling channel 26 is disposed close to a top of the cylinder barrel
11. It will be noted that the top of the cylinder barrel 11 is close to a combustion
chamber, and therefore, the top position of the cylinder barrel 11 is greatly affected
by a heat load. Because the coolant in the cooling channel 24 passes through the junction
between the first cooling channel 25 and the second cooling channel 26, the junction
between the first cooling channel 25 and the second cooling channel 26 is disposed
close to the top of the cylinder barrel 11. In this way, when passing through the
junction between the first cooling channel 25 and the second cooling channel 26, the
coolant can better cool and lower the temperature of the top of the cylinder barrel
11, thereby improving an overall cooling effect of the cylinder body 1. A distance
between the top of the cylinder barrel 11 and the junction between the first cooling
channel 25 and the second cooling channel 26 is about 14 mm, so that the junction
between the first cooling channel 25 and the second cooling channel 26 may be as close
to the highest temperature point of the cylinder hole as possible while satisfying
processing requirements. In addition, a diameter of the cooling channel 24 is about
3 mm, so that it can be ensured that the cooling channel 24 does not interfere with
a burr on the cylinder body 1 to prevent coolant leakage.
[0041] According to an optional embodiment of this application, as shown in FIG. 1, the
cylinder barrel water jacket 21 is inwardly recessed at a junction between two adjacent
cylinder barrels 11. It will be understood that the cylinder barrel water jacket 21
is inwardly recessed at a junction between two adjacent cylinder barrels 11. In this
way, when the coolant passes through the junction between the two adjacent cylinder
barrels 11, a contact area between the coolant and the junction between the two adjacent
cylinder barrels 11 may be increased, and the coolant is closer to the highest temperature
point between the two adjacent cylinder barrels 11, thereby further improving an effect
of performing cooling and temperature lowering between the two adjacent cylinder barrels
11 by the coolant. The cylinder barrel water jacket 21 has an inwardly recessed dimension
of about 3.5 mm at the junction between two adjacent cylinder barrels 11, and a depth
dimension is about 10 mm.

body 1 in any one of the foregoing embodiments, as shown in FIG. 5.
[0043] A vehicle 1000 according to this embodiment of this application includes the engine
