Description

Technical Field

[0001] The utility model relates to an engine device, and in particular to an engine device suitable for being applied in a driving object device. Background Art

[0002] In recent years, research and development efforts to improve fuel efficiency, which contributes to energy efficiency, have been underway to ensure more people have access to affordable, reliable, sustainable, and advanced energy. However, heating the oil in vehicle engines remains a challenge within these technologies.

[0003] In the prior art, a container, serving as a driven device, can be equipped with an engine device as a power source and a refrigerating machine for transporting frozen goods. For example, the container loaded with frozen goods is mounted on a vehicle, such as a truck, towed by a tractor, allowing the container, serving as the driven device, to move in the direction of travel of the truck. The engine device comprises an engine body, an oil pan, and an exhaust pipe. The engine body and exhaust pipe can be mounted at the rear or front of the vehicle for exhaust, and the oil pan can be located at the bottom of the engine body. For example, an oil passage is provided to guide the oil to the exhaust pipe, where it passes through an oil heating unit located inside or outside the exhaust pipe before returning to the engine body. Heating and heating can be controlled by opening or closing a control valve in the oil passage according to the oil temperature. Alternatively, fins can be installed in the oil pan adjacent to the exhaust pipe to increase the heated surface area, thereby heating the oil flowing into the oil pan. However, using a control valve and oil passage to direct oil to the exhaust pipe is not only complex and costly, but also poses a risk of burnout when the control valve is closed, as the oil temperature in the passage rises. Furthermore, installing fins within the oil pan limits the production process and can increase weight. Therefore, improvements are needed to improve the heating methods used to increase the temperature of the engine unit.

[0004] In order to solve the above-mentioned problems, the present invention aims to achieve an improved oil heating effect by using a heating means with a simplified structure, and further contribute to energy efficiency. Utility Model Content

[0005] The utility model provides an engine device, which can improve the heating effect of oil by using a heating means with a simplified structure.

[0006] The utility model provides an engine device, which is suitable for use in a driven object device and includes: an engine body, which is mounted in front of the driven object device in a front-to-rear direction and drives the driven object device as a power source; an oil pan, which is arranged at the bottom of the engine body; and an exhaust pipe, which is arranged in front of the engine body, wherein the exhaust pipe extends from the front of the oil pan through the side of the oil pan to the rear of the oil pan and extends along the rear surface of the oil pan.

[0007] In an embodiment of the present invention, a rear section of the exhaust pipe extending along the rear surface of the oil pan extends obliquely behind the oil pan.

[0008] In an embodiment of the present invention, the exhaust pipe is arranged to match the oil level in the oil pan.

[0009] In an embodiment of the present invention, the engine device further includes a catalyst component disposed in front of the engine body, and the exhaust pipe extends on the downstream side of the catalyst component.

[0010] In an embodiment of the present invention, the driven device includes a container carrying a refrigerator, and the engine body, the oil pan, and the exhaust pipe are arranged in front of the container.

[0011] Based on the above, in the engine device of the present invention, an engine body is mounted in front of a driven device as a power source, an oil pan is disposed at the bottom of the engine body, and an exhaust pipe is disposed in front of the engine body. The exhaust pipe extends from the front of the oil pan, through the sides of the oil pan, to the rear of the oil pan, and along the rear surface of the oil pan. This allows the oil in the oil pan to be heated by heat energy dissipated from at least the portion of the exhaust pipe surrounding the sides and rear of the oil pan. In particular, when the driven device on which the engine device is mounted is moving forward (e.g., driving), outside air flows from the front of the driven device and the engine device to the rear. In this case, at least the portion of the exhaust pipe surrounding the sides and rear of the oil pan is not directly exposed to the outside air blowing from the front (i.e., the heat energy in the lateral and rear sections of the exhaust pipe is less likely to be dissipated by the outside air), allowing the oil in the oil pan to be effectively heated. As a result, the oil absorbs the heat energy from the exhaust pipe, heating it earlier and reducing friction in the low-load operating range during the warm-up period. Accordingly, the engine device of the present invention can improve the heating effect of the oil through a heating method with a simplified structure.

[0054] Below, with reference to the attached Figure 1 The embodiments of the present invention are described below. Figure 1 This is a partially enlarged schematic diagram of a driven device equipped with an engine device according to an embodiment of the present invention. Figure 2 yes Figure 1 The engine installation shown is a three-dimensional schematic diagram from the front perspective, Figure 3 yes Figure 2 The engine installation shown is a three-dimensional schematic diagram from the rear perspective, Figure 4 yes Figure 2 The engine unit shown is a plan view from the bottom. Figure 5 yes Figure 2 The engine unit shown is a cross-sectional view of the oil pan and exhaust pipe after partial cutting. Figures 1 to 5The specific structures of the engine device 100 and the driven device 50 equipped with the engine device 10 in this embodiment are described. However, this is only an example and the present invention is not limited thereto and can be adjusted according to needs.

[0055] Please refer to Figures 1 to 4 In the present embodiment, the engine device 100 is suitable for application in the driven object device 50, and the engine device 100 includes an engine body 110, an oil pan 120, and an exhaust pipe 130. The engine body 110 is mounted in front of the driven object device 50 in the front-to-rear direction X, and drives the driven object device 50 as a power source. The oil pan 120 is provided at the bottom of the engine body 110 (i.e., below the up-down direction Z). The exhaust pipe 130 is provided in front of the engine body 110. Among them, the exhaust pipe 130 extends from the front of the oil pan 120 through the side of the oil pan 120 (i.e., one side of the left-right direction Y) to the rear of the oil pan 120, and extends along the rear surface 120S of the oil pan 120 (as shown in FIG. Figure 3 and Figure 4 shown).

[0056] Specifically, in this embodiment, Figure 1 As shown, the driven device 50 is, for example, a container including a refrigerator 52, and the engine body 110, the oil pan 120, and the exhaust pipe 130 of the engine device 100 are arranged in front of the container as the driven device 50 ( Figure 1 The portion of the driven object device 50 where the refrigerator 52 and the engine device 100 are mounted is shown as an example. That is, the entire engine device 100 is mounted on the front portion of the driven object device 50 (for example, on the front wall of the outer shell 54 of the driven object device 50). The refrigerator 52 includes, for example, a radiator 52a, a refrigerator compressor 52b, a refrigeration component 52c, and a cooling water pipe 52d connecting the radiator 52a and the engine body 110. The specific structure of the refrigerator 52 and the driven object device 50 can be adjusted according to needs. In addition, the container carrying the refrigerator 52 can be used to transport frozen goods, for example, by installing the container (driven object device 50) loaded with frozen goods on a vehicle (not shown) such as a truck towed by a traction device, so that the container serving as the driven object device 50 can move along the direction of travel of the truck. However, the driven device 50 is not limited to a container equipped with the refrigerator 52 , and may be a container equipped with no refrigerator 52 , or may be another device or another vehicle driven by the engine device 100 as a power source.

[0057] The present invention is not limited thereto and can be adjusted according to needs.

[0058] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, the engine body 110 of the engine device 100 includes, for example, a cylinder 111 composed of a cylinder cover 111a, a cylinder head 111b, and a cylinder block 111c that are stacked in the vertical direction Z, a chain case 112 provided on the side of the cylinder 111 (i.e., on one side in the left-right direction Y), and an intake manifold 113 (e.g., connected to the cylinder head 111b) at the rear of the cylinder 111. Figure 3 In addition, the intake manifold 113 of the engine body 110 is connected to the air cleaner 116 (as shown) through the air duct 114 and the throttle valve 115. Figure 2 and Figure 3 As shown) and guides, throttles and purifies the air. As an example, the engine body 110 is provided with a driving component (such as a pulley 117 and a belt 118) on one side of the cylinder 111 in the left-right direction Y. Figure 1 As shown), it is connected to the driven object device 50 and serves as a power source to drive the driven object device 50. However, the present invention does not limit the specific structure of the engine body 110, which can be adjusted according to needs.

[0059] In addition, in this embodiment, Figure 2 and Figure 3 As shown, the oil pan 120 of the engine device 100 is a housing structure that is generally flat, disc-shaped, or box-shaped and extends on a plane. It is disposed at the bottom of the engine body 110 along the lower surface of the engine body 110, thereby receiving oil (not shown) from the engine body 110. The dimensions of the oil pan 120 in the front-to-back direction X and the left-to-right direction Y are generally corresponding to the dimensions of the engine body 110 (e.g., Figure 2 and Figure 3 A clutch bell housing 122 is provided on one side of the oil pan 120 in the left-right direction Y. The clutch bell housing 122 extends upward relative to the oil pan 120 in the vertical direction Z, thereby serving as a partition between the cylinder block 111c and the refrigerator compressor 52b when the engine device 100 is mounted on the driven device 50 (as shown in FIG. Figure 1In addition, an oil filter 124 may be provided in front of the oil pan 120 for filtering the oil in the oil pan 120. However, the present invention does not limit the specific structure of the oil pan 120, which may be adjusted according to needs.

[0060] Furthermore, in this embodiment, if Figures 2 to 4 As shown, the exhaust pipe 130 of the engine device 100 is a tubular member for exhaust, and has a front section 132, a side section 134, and a rear section 136 extending from the front of the engine body 110 through the side to the rear. The exhaust pipe 130 is provided at the front surface of the engine body 110 (as shown in FIG. Figure 2 ), and the front section 132, the side section 134, and the rear section 136 sequentially extend from the front of the oil pan 120 through the side of the oil pan 120 (for example, the space between the oil pan 120 and the clutch cover 122) to the rear of the oil pan 120 (as shown). Figure 3 As shown). Figure 4 As shown, the exhaust pipe 130 surrounds the front, side, and rear sides of the oil pan 120, and a portion of the exhaust pipe 130 (i.e., the rear section 136) extends along the rear surface 120S of the oil pan 120. As an example, Figure 3 and Figure 4 As shown, the length L1 of the rear section 136 of the exhaust pipe 130 is greater than the length L2 of the side section 134 of the exhaust pipe 130 and greater than the length L3 of the front section 139. However, the present invention does not limit the specific structure of the exhaust pipe 130, which can be adjusted according to needs.

[0061] Through the above configuration, in the engine device 100 of this embodiment, as Figure 4 and Figure 5 As shown, the oil in the oil pan 120 can be heated by the heat energy emitted from at least the side and rear parts of the exhaust pipe 130 surrounding the oil pan 120 (for example, the side section 134 and the rear section 136). In particular, when the driven object device 50 equipped with the engine device 100 moves toward the front (for example, driving), the outside wind flows from the front to the rear of the driven object device 50 and the engine device 10. At this time, at least the side and rear parts of the exhaust pipe 130 surrounding the oil pan 120 (for example, the side section 134 and the rear section 136) will not directly receive the outside wind blowing from the front (that is, the heat energy of the side section 134 and the rear section 136 of the exhaust pipe 130 is not easily blown away by the outside wind), and can effectively heat the oil in the oil pan 120 (for example, Figure 5As shown in the figure, the oil absorbs the heat energy from the exhaust pipe 130 and heats up early, reducing friction in the low-load operating range during the warm-up period. Thus, the engine device 100 can improve the oil heating effect through a simplified heating method.

[0062] Furthermore, in this embodiment, if Figure 3 As shown, the rear section 136 of the exhaust pipe 130 extending along the rear surface 120S of the oil pan 120 extends obliquely behind the oil pan 120. As an example, the rear section 136 of the exhaust pipe 130 can be provided with a length greater than the long side of the rear surface 120S of the oil pan 120. That is, the rear section 136 of the exhaust pipe 130 is provided obliquely corresponding to the diagonal line of the rear surface 120S of the oil pan 120, so that the length L1 of the rear section 136 of the exhaust pipe 130 is greater than the length L4 of the long side of the rear surface 120S of the oil pan 120 (as shown in FIG. 1 ). Figure 3 As shown in the figure, the area receiving the heat from the exhaust pipe 130 is increased, and the oil in the oil pan 120 can effectively absorb the heat from the exhaust pipe 130, heating it earlier, thereby effectively heating the oil in the oil pan 120. However, in other embodiments not shown, the rear section 136 of the exhaust pipe 130 can also extend horizontally behind the oil pan 120. The present invention does not limit the location of the exhaust pipe 130, and it can be adjusted according to needs.

[0063] Furthermore, in this embodiment, if Figure 5 As shown, the exhaust pipe 130 is provided to match the oil level H in the oil pan 120. As an example, the oil pan 120 is a housing structure that is generally flat, disc-shaped, or box-shaped, so that the oil level in the oil pan 120 is also generally flat and parallel to the bottom surface of the oil pan 120. In addition, a portion of the exhaust pipe 130 (e.g., the side section 134 and the rear section 136) extends from bottom to top in the vertical direction Z and extends obliquely through a height position corresponding to the oil level H in the oil pan 120 (e.g., Figure 3 As shown). In this way, the exhaust pipe 130 is set corresponding to the oil level H in the oil pan 120 (as shown). Figure 5 (as shown), the area receiving the heat from the exhaust pipe 130 is increased, and the oil in the oil pan 120 can effectively absorb the heat from the exhaust pipe 130, heating it earlier, thereby effectively heating the oil in the oil pan 120. However, in other embodiments not shown, the rear section 136 of the exhaust pipe 130 may also extend horizontally behind the oil pan 120 at a height corresponding to the oil level H in the oil pan 120. The present invention does not limit the location of the exhaust pipe 130, and it can be adjusted as needed.

[0064] In addition, in this embodiment, Figure 2 and Figure 3 As shown, the engine device 100 further includes a catalyst component 140. The catalyst component 140 is disposed in front of the engine body 110, and the exhaust pipe 130 extends downstream of the catalyst component 140. As an example, the catalyst component 140 is disposed between the front surface of the engine body 110 and the end 138 of the exhaust pipe 130 corresponding to the front section 132. That is, the exhaust pipe 130 is connected to the engine body 110 via the catalyst component 140 at the end 138 corresponding to the front section 132. In this way, the exhaust gas from the engine body 110 first passes through the catalyst component 140 before flowing into the exhaust pipe 130. In addition, because the catalyst component 140 converts harmful substances in the exhaust gas into harmless substances through a chemical reaction, and the conversion action is performed at a high temperature, the exhaust gas temperature on the downstream side of the catalyst component 140 is higher than the exhaust gas temperature on the upstream side. Thus, by locating the exhaust pipe 130 downstream of the catalyst component 140, the exhaust gas flowing into the exhaust pipe 130 can be heated to a high temperature, thereby effectively heating the oil in the oil pan 120 via the high-temperature exhaust pipe 130. However, the present invention does not limit the location of the exhaust pipe 130 and the catalyst component 140, nor the presence or absence of the catalyst component 140, and these can be adjusted according to needs.

[0065] In summary, in the engine device of the present invention, the engine body is mounted in front of the driven device as a power source, the oil pan is disposed at the bottom of the engine body, and the exhaust pipe is disposed in front of the engine body. The exhaust pipe extends from the front of the oil pan through the sides of the oil pan to the rear of the oil pan, and extends along the rear surface of the oil pan. Preferably, the rear section of the exhaust pipe extends obliquely behind the oil pan, and / or the exhaust pipe is positioned to match the oil level within the oil pan. In this manner, the oil within the oil pan can be heated by heat energy emitted from at least the portion of the exhaust pipe surrounding the sides and rear of the oil pan. In particular, when the driven device equipped with the engine device is moving forward (e.g., driving), outside air flows from the front of the driven device and the engine device to the rear. At this point, at least the lateral and rearward portions of the exhaust pipe surrounding the oil pan are shielded from direct wind blowing from the front (i.e., heat energy from the lateral and rearward sections of the exhaust pipe is less likely to be dissipated by the wind), effectively heating the oil within the oil pan. This allows the oil to absorb heat from the exhaust pipe, heating up early and reducing friction in the low-load operating range during the warm-up period. Consequently, the engine system of the present invention achieves enhanced oil heating efficiency through a simplified heating method.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
