[0033] Specifically, the first hard tube 201, the second hard tube 202, the third hard tube 203 and the fourth hard tube 204 are all components of the hard tube assembly 200 and can play a supporting role.

One end of a hose 211 is connected to the first hard pipe 201, and the other end of the first hose 211 is connected to the water inlet. The two ends of the first hose 211 are respectively connected to the first hard pipe 201 and the water inlet. One end of the second hose 212 is connected to the second hard pipe 202, and the other end of the second hose 212 is connected to the return water port. The two ends of the second hose 212 are respectively connected to the second hard pipe 202 and the return water port. The first hose 211 and the second hose 212 are not only convenient to connect, but also can reduce shock when connected to the engine and are not easily damaged. One end of the third hose 213 is connected to the third hard pipe 202. 3, and the other end of the third hose 213 is connected to the water inlet, both ends of the third hose 213 are respectively connected to the third hard pipe 203 and the water inlet, one end of the fourth hose 214 is connected to the fourth hard pipe 204, and the other end of the fourth hose 214 is connected to the water outlet, and both ends of the fourth hose 214 are respectively connected to the fourth hard pipe 204 and the water outlet. At this time, water can be taken from the engine 10 to heat the liquefier. It can be applicable to the direction of the water inlet and return pipes at different positions of the engine 10, thereby providing a sufficient heat source for vaporization and ensuring the smooth operation of the gas system.

[0034] Among them, such as Figure 1As shown, the connecting pipe assembly 20 also includes: two connecting bracket assemblies 220, the two connecting bracket assemblies 220 are respectively connected to the engine 10, and one connecting bracket assembly 220 is connected to the first hard pipe 201 and the second hard pipe 202, and the other connecting bracket assembly 220 is connected to the third hard pipe 203 and the fourth hard pipe 204. The connecting bracket assembly 220 can mainly provide connection and fixing functions to ensure the stability and safety of the structure. The two connecting bracket assemblies 220 are respectively connected to the engine 10, and one connecting bracket assembly 220 is connected to the first hard tube 201 and the second hard tube 202, and the other connecting bracket assembly 220 is connected to the third hard tube 203 and the fourth hard tube 204. One connecting bracket assembly 220 is respectively connected to the first hard tube 201, the second hard tube 202 and the engine 10, and the other connecting bracket assembly 220 is respectively connected to the third hard tube 203, the fourth hard tube 204 and the engine 10, so that the first hard tube 201, the second hard tube 202, the third hard tube 203 and the fourth hard tube 204 can be fixed on the engine 10, thereby ensuring the stability and safety of the overall structure of the engine system 1.

[0035] In addition, if Figure 1 、 Figure 3 and Figure 4 As shown, the two connecting bracket assemblies 220 each include: at least two connecting brackets 221, and the at least two connecting brackets 221 are spaced apart. The connecting brackets 221 can mainly play a connecting and fixing role. The two connecting bracket assemblies 220 each include: at least two connecting brackets 221, and the number of connecting brackets 221 included in the two connecting bracket assemblies 220 is greater than or equal to two. The at least two connecting brackets 221 are spaced apart. This can avoid interference between the multiple connecting brackets 221, and at the same time, the multiple connecting brackets 221 can be distributed over a wider range, and to a certain extent, it can also improve the supporting stability of the connecting bracket assembly 220.

[0036] Of course, if Figure 1 and Figure 4As shown, at least two connecting brackets 221 are each provided with a mounting hole 222, and the mounting hole 222 on at least one connecting bracket 221 is configured as a special-shaped structure. The mounting holes 222 primarily serve a mounting function. At least two connecting brackets 221 are each provided with a mounting hole 222. The connecting brackets 221 can be connected to the engine 10 and the first, second, third, and fourth rigid tubes 201, 202, 203, and 204 through the mounting holes 222, thereby securing the first, second, third, and fourth rigid tubes 201, 202, 203, and 204 to the engine 10. The mounting hole 222 on at least one connecting bracket 221 is configured as a special-shaped structure. This effectively improves the installation convenience of the connecting pipe assembly 20 and prevents installation failures due to dimensional errors. The connecting pipe assembly 20 can be secured to the rear and side of the engine 10 using two bolts and two nuts. This four-point fixation is more stable and reliable, reducing the risk of damage to the connecting pipe assembly 20 during use.

[0037] Furthermore, if Figure 3 and Figure 4 As shown, the connecting bracket 221 includes: a first connecting part 223 and a second connecting part 224, the first connecting part 223 is wrapped around the first hard tube 201 and the second hard tube 202, or the third hard tube 203 and the fourth hard tube 204, the second connecting part 224 is connected to the first connecting part 223, and the second connecting part 224 is connected to the engine 10.

[0038] It should be noted that the first connecting part 223 and the second connecting part 224 are components of the connecting bracket 221, and both can play a connecting role. The first connecting part 223 is wrapped around the first hard tube 201 and the second hard tube 202, or the third hard tube 203 and the fourth hard tube 204. At this time, the structural strength of the connecting pipe assembly 20 can be ensured while its direction is relatively constrained. The second connecting part 224 is connected to the first connecting part 223, and the second connecting part 224 and the first connecting part 223 are in a connected state. The second connecting part 224 is connected to the engine 10, the first connecting part 223 is connected to the first hard tube 201, the second hard tube 202, the third hard tube 203 and the fourth hard tube 204, and the second connecting part 224 is connected to the engine 10, so that the connection between the connecting pipe assembly 20 and the engine 10 can be realized. Among them, the first connecting part 223 can be wrapped around the first hard tube 201 and the second hard tube 202, or the third hard tube 203 and the fourth hard tube 204 in a semi-enclosed manner, and the first connecting part 223 can be wrapped around the first hard tube 201 and the second hard tube 202, or the third hard tube 203 and the fourth hard tube 204 by welding. This can make the weld smooth, the size accurate, the structure simple and elegant, and can ensure the firmness and reliability of the connection between the first connecting part 223 and the first hard tube 201 and the second hard tube 202, or the third hard tube 203 and the fourth hard tube 204.

[0039] In addition, Figure 1 As shown, the connecting pipe assembly 20 further includes a tightening member 230, which is provided at least at the first rigid pipe 201 and the second rigid pipe 202 to tighten the first rigid pipe 201 and the second rigid pipe 202. The tightening member 230 can effectively prevent excessive relative vibration between the connecting pipe assembly 20 due to the excessive cantilever of the connecting pipe assembly 20. The tightening member 230 is provided at least at the first rigid pipe 201 and the second rigid pipe 202 to tighten the first rigid pipe 201 and the second rigid pipe 202. The first rigid pipe 201 and the second rigid pipe 202 are provided on the side of the engine 10. The first rigid pipe 201 and the second rigid pipe 202 are long and need to be tightened and constrained. This can effectively prevent excessive relative vibration between the first rigid pipe 201 and the second rigid pipe 202 due to the excessive cantilever of the first rigid pipe 201 and the second rigid pipe 202, which can easily cause damage to the first rigid pipe 201 and the second rigid pipe 202. Of course, the tightening member 230 can also be set at the third hard tube 203 and the fourth hard tube 204.

[0040] It should be noted that if Figure 1As shown, the hose assembly 210 further includes a fifth hose 215 and a sixth hose 216. The fifth hose 215 is connected between the first rigid tube 201 and the third rigid tube 203, and the sixth hose 216 is connected between the second rigid tube 202 and the fourth rigid tube 204. The fifth hose 215 and the sixth hose 216 are both components of the hose assembly 210 and can serve as intermediate connections. The fifth hose 215 is connected between the first rigid tube 201 and the third rigid tube 203, with both ends of the fifth hose 215 connected to the first rigid tube 201 and the third rigid tube 203, respectively. The sixth hose 216 is connected between the second rigid tube 202 and the fourth rigid tube 204, with both ends of the sixth hose 216 connected to the second rigid tube 202 and the fourth rigid tube 204, respectively. At this point, the connecting pipe assembly 20 is connected, allowing water to be drawn from the engine 10 to heat the liquefier. This can be adapted to the directions of the water inlet and return pipes at different locations on the engine 10, thereby providing a sufficient heat source for vaporization and ensuring smooth operation of the gas system.

[0041] In addition, if Figure 1 As shown, the connecting pipe assembly 20 further includes a clamping member 240, which is clamped at the connection between the hard pipe assembly 200 and the hose assembly 210 to clamp the hose assembly 210 to the hard pipe assembly 200. The clamping member 204 can mainly fix and connect two or more components to ensure that they will not separate or move when subjected to external force or vibration. The clamping member 240 is clamped at the connection between the hard pipe assembly 200 and the hose assembly 210 to clamp the hose assembly 210 to the hard pipe assembly 200. At this time, leakage at the connection between the hard pipe assembly 200 and the hose assembly 210 during the vaporization process can be prevented, which may affect the service life of the engine system 1.
