Description

Technical Field

[0001] The invention relates to the technical field of cylinder cooling of an internal combustion engine, in particular to a cylinder of an internal combustion engine. Background Art

[0002] An engine block is a structure that contains the cylinders and other components of an internal combustion engine. In early automotive engines, the engine block consisted of just the cylinder block, with a separate crankcase attached. Modern engine blocks often integrate the crankcase with the cylinder block as a single component. The engine block also typically includes elements such as coolant passages and oil galleries. The term cylinder block is often used interchangeably with engine block, although technically a modern engine's block (i.e., multiple cylinders in a single component) would be classified as a monoblock.

[0003] An engine is a machine that converts chemical energy into mechanical energy. Its conversion process is actually the process of the working cycle. Simply put, it generates kinetic energy by burning the fuel in the cylinder, which drives the reciprocating motion of the piston in the engine cylinder, thereby driving the connecting rod connected to the piston and the crank connected to the connecting rod to make reciprocating circular motion around the center of the crankshaft to output power.

[0004] The engine's cylinder block is where the fuel burns, and the fuel combustion will generate a lot of heat. If the heat of the cylinder block is not reduced in time, it may cause damage to the cylinder block. Existing cooling methods include wind cooling and water cooling. When using natural wind to reduce the temperature of the cylinder block, the heat of the cylinder block is taken away by a steady stream of wind. However, when the wind blows, the contact time between the wind and the cylinder block is very limited. Usually, the wind will leave as soon as it touches the cylinder block, which will greatly reduce the cooling effect on the cylinder block, causing the engine to be damaged due to excessive temperature after long-term use.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For example, see Figures 1 to 10 The present embodiment provides a cylinder block of an internal combustion engine, including a cylinder block 7, a piston groove 4 is provided on the upper surface of the cylinder block 7, a sealing shell 1 is fixedly connected to the upper surface of the cylinder block 7, two sealing shells 1 are provided, the upper surface of the other sealing shell 1 is fixedly connected to the lower surface of the cylinder block 7, a mounting frame 3 is fixedly connected to the side of the sealing shell 1, a cooling pipe 6 is also provided on the side of the cylinder block 7, an air intake assembly is provided in the cooling pipe 6, and the air intake assembly includes:

[0043] In this embodiment, the motor vehicle equipped with the cylinder body will have wind resistance during driving, and the wind will enter the cooling pipe 6 through the intake pipe 5, and then contact the surface of the cylinder body 7 through the cooling pipe 6, so that the natural wind will take away the heat on the surface of the cylinder body 7 during the flow, thereby achieving a cooling effect, and when the wind enters the intake pipe 5, it will also push the wind deflector 12 to move in the direction of the intake pipe 5, thereby driving the fixing plate 15 to slide in the fixing cylinder 29, and then compressing the spring 16. When the motor vehicle stops, it will also recover under the action of the spring 16;

[0044] The setting of the air intake assembly cools the cylinder body 7 through natural wind, thereby preventing the cylinder body 7 from being damaged due to temperature increase during long-term operation. The setting of the shielding net 11 prevents foreign matter from entering the air intake pipe 5 and damaging the air intake pipe 5. In addition, the wind deflector 12 can be closer to the air inlet of the air intake pipe 5 during the movement of the motor vehicle, thereby further reducing the possibility of foreign matter entering the air intake pipe 5.

[0045] It is worth noting that, in this embodiment, the air inlet enlargement component is arranged in the air inlet pipe 5, and the air inlet enlargement component includes:

[0046] A movable column 18, a wind deflector 19 and a wind deflector 21, the end surface of the movable column 18 facing the wind deflector 12 is fixedly connected to the end surface of the sliding rod 14, the surface of the movable column 18 is slidably connected to the inner wall of the fixed cylinder 29, and the surface of the movable column 18 is also provided with an arc-shaped sliding groove 22 which is not connected at the first position;

[0047] A fixed column 23, the surface of the fixed column 23 is slidably connected to the groove wall of the arc-shaped slide groove 22, the end surface of the fixed column 23 is fixedly connected to the inner wall of the second windshield plate 21, and the inner wall of the second windshield plate 21 is slidably connected to the surface of the movable column 18, and the outer surface of the second windshield plate 21 is rotatably connected to the inner wall of the intake pipe 5;

[0048] The end face of the fixed cylinder 29 away from the wind shield 12 is fixedly connected to the end face of wind shield 19, the outer surface of wind shield 19 is fixedly connected to the inner wall of the air inlet pipe 5, the inner wall of wind shield 19 is slidingly connected to the surface of the movable column 18, the end face of wind shield 19 is rotatably connected to the end face of wind shield 2 21, and the end faces of wind shield 19 and wind shield 2 21 are staggered to provide air inlets.

[0049] In this embodiment, when the wind deflector 12 moves toward the direction of the air inlet pipe 5, it will drive the sliding rod 14 to move toward the inside of the air inlet pipe 5, further pushing the moving column 18 to move toward the inside of the air inlet pipe 5, thereby driving the fixed column 23 to slide in the arc-shaped slide groove 22, and further driving the wind deflector 21 to rotate. Since the end faces of the wind deflector 19 and the wind deflector 21 are provided with staggered air inlets, the wind deflector 19 does not rotate, while the wind deflector 21 rotates, so that the air inlets on the wind deflector 19 and the wind deflector 21 can be gradually aligned, so that natural wind can enter the air inlet pipe 5, and the greater the distance that the sliding rod 14 moves toward the inside of the air inlet pipe 5, the greater the rotation angle of the wind deflector 19 will be, so that the range of the wind deflector 19 and the air inlets on the wind deflector 21 will be larger, and the natural wind will enter more smoothly.

[0050] The setting of the air inlet enlargement component drives the wind shield plate 21 to rotate when the wind shield plate 12 moves in the direction of the air inlet pipe 5, and the greater the distance the wind shield plate 12 moves, the greater the rotation angle of the wind shield plate 21 will be, so that the range of alignment between the wind shield plate 19 and the air inlet on the wind shield plate 21 will be larger, so that the cylinder body can automatically adjust the amount of air intake according to the driving speed, thereby further improving the cooling effect on the cylinder body, and when the wind shield plate 12 returns to its original position, the wind shield plate 21 will also return to its original position, so that the air inlet on the wind shield plate 19 and the wind shield plate 21 will be staggered, further preventing foreign matter from entering the air inlet pipe 5.

[0051] Embodiment 2, based on the above embodiment:

[0052] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.10 The blocking component is also arranged in the air intake pipe 5, and the blocking component includes:

[0053] A set of baffles 24 and moving rods 20, the end face of the moving rod 20 is fixedly connected to the end face of the moving column 18 facing the inside of the intake pipe 5, the surface of the moving rod 20 is also fixedly connected to the limit ring 32, the surface of the moving rod 20 is provided with a through push groove 31, the groove wall of the push groove 31 is slidably connected to the disc block 30, the arc surface of the disc block 30 is fixedly connected to the right angle frame 25, the right angle end of the right angle frame 25 is rotatably connected to the rotating column 26, both ends of the rotating column 26 are fixedly connected to the inner wall of the intake pipe 5, and the end of the right angle frame 25 away from the disc block 30 is fixedly connected to the end face of the baffle 24

[0054] In this embodiment, when the wind shield plate 12 moves toward the direction of the air intake pipe 5, it will also drive the moving rod 20 to move toward the inside of the air intake pipe 5, so that the disc block 30 is pushed to move by the pushing groove 31, and the right-angle frame 25 is further rotated with the rotating column 26 as the axis, which will drive the baffle plate 24 to deflect, so as to expand to slow down the natural wind from the cooling pipe 6.

[0055] The setting of the blocking component drives the baffle 24 to deflect while the wind baffle 12 moves in the direction of the intake pipe 5, thereby expanding to slow down the natural wind coming out of the cooling pipe 6, thereby increasing the time the natural wind stays in the cooling pipe 6, thereby increasing the contact time between the natural wind and the cylinder body 7, improving the efficiency of the natural wind in carrying away heat, and further improving the cooling effect on the cylinder body 7.

[0056] Embodiment 3, based on the above embodiment:

[0057] See also Figure 2 , Figure 4 and Figure 8 The cooling water assembly is arranged in the cooling pipe 6, and the cooling water assembly comprises:

[0058] A water spray row 9 and a fixing rod 8, one end of the fixing rod 8 is fixedly connected to the surface of the water spray row 9, and the other end of the fixing rod 8 is fixedly connected to the side of the cylinder body 7. The side of the water spray row 9 facing away from the cylinder body 7 is fixedly connected to the water inlet pipe 2, and the side of the water spray row 9 facing the cylinder body 7 is fixedly connected to the atomizing nozzle 13, the water spray end of the atomizing nozzle 13 penetrates the inner wall of the cooling pipe 6, and the inner wall of the cooling pipe 6 is also fixedly connected to the water outlet pipe 10;

[0059] Spring 27, one end of spring 27 is fixedly connected to the end face of the water spray row 9 facing the cooling pipe 6, the other end of spring 27 is fixedly connected to the pressure sensor 28, the end of the moving rod 20 away from the wind deflector 12 penetrates the inner wall of the cooling pipe 6, and the end face of the moving rod 20 that penetrates the inner wall of the cooling pipe 6 abuts against the end face of the pressure sensor 28.

[0060] In this embodiment, when the moving rod 20 moves toward the inside of the air intake pipe 5, the moving rod 20 will be driven to squeeze the pressure sensor 28 and the spring 27, further driving the pressure sensor 28 to move toward the direction of the water spray row 9, and then the pressure sensor 28 uses the pressure it receives to transmit a signal to the atomizing nozzle 13, so that it sprays the atomized coolant into the cooling pipe 6 and mixes it with the natural wind in the cooling pipe 6, so that it is mixed more evenly in the cooling pipe 6, and when the pressure on the pressure sensor 28 is large, the spraying amount of the atomizing nozzle 13 is large, and when the pressure on the pressure sensor 28 is small, the spraying amount of the atomizing nozzle 13 is small;

[0061] The setting of the cooling water component sprays atomized coolant into the cooling pipe 6 through the atomizing nozzle 13, and mixes it with natural wind to make it mixed more evenly in the cooling pipe 6, thereby further improving the cooling effect on the cylinder body 7, and also utilizes the pressure sensor 28 so that the spraying amount of the atomizing nozzle 13 is different when the pressure sensor 28 is subjected to different pressures, thereby further saving the use of coolant.

[0062] Working principle: When the cylinder block of an internal combustion engine is used, the following steps are performed:

[0063] S1: First, the wind resistance generated by the motor vehicle equipped with the cylinder body during driving is used to drive the wind deflector 12 to move toward the direction of the intake pipe 5, so that the device can cool the cylinder body 7;

[0064] S2: Then, the wind shield plate 12 moves toward the direction of the air inlet pipe 5, driving the sliding rod 14 to move toward the inside of the air inlet pipe 5, thereby driving the wind shield plate 2 21 to rotate, so that the wind shield plate 1 19 is gradually aligned with the air inlet on the wind shield plate 2 21, so that the natural wind enters the air inlet pipe 5;

[0065] S3: At the same time, the second moving rod 20 is also driven to move toward the inside of the air intake pipe 5, and then the baffle 24 is deflected under the action of the rotating column 26, so as to be expanded to slow down the natural wind coming out of the air intake pipe 5, thereby improving the cooling efficiency;

[0066] S4: The movement of the moving rod 20 will also squeeze the pressure sensor 28. The pressure sensor 28 uses the pressure to transmit a signal to the atomizing nozzle 13, so that it sprays atomized coolant into the cooling pipe 6 and mixes the sprayed atomized coolant with the natural wind to improve the cooling effect on the cylinder 7;

[0067] S5: Finally, when the motor vehicle equipped with the cylinder block stops, the wind deflector 12 is restored under the action of the spring 16, and further drives the wind deflector 21, the baffle 24 and the pressure sensor 28 to restore.
