[0036] like Figures 2 to 7 As shown, a compact engine includes an engine body, which includes a housing 1 and a cylinder head 2 integrally formed on the housing. A cylinder head 3 is mounted on the cylinder head. The engine body also includes a fuel tank 4, an air filter 5, and a muffler 6 mounted on the housing. The cylinder head is integrally formed on one side of the upper end of the housing, tilted outward and upward, such that the cylinder head is axially angled with the housing.

[0037] Thus, in the engine structure described above, the cylinder head is integrally formed by tilting it outward and upward on one side of the upper end of the housing, so that the cylinder head and the housing are arranged at an angle, making the vertical dimension of the entire engine structure smaller and the vertical layout more compact.

[0038] In this specific embodiment, the included angle between the cylinder head axis and the housing is 25° to 45°.

[0039] This design, with the angle between the cylinder head and the housing set to 25° to 45°, makes the angle between the cylinder head and the housing set more reasonable.

[0040] In this specific embodiment, the angle between the cylinder head axis and the housing is 32°.

[0041] Therefore, setting it to 32° makes the angle more reasonable.

[0042] In this specific embodiment, two mounting blocks 7 are arranged in pairs on the upper end of the housing and on the side away from the cylinder head. A support block 8 is arranged on the upper side of the cylinder head, and the oil tank is arranged above the support block and the two mounting blocks. The support block is connected to one end of the oil tank, and an upwardly mounted mounting plate 9 is detachably connected to the two mounting blocks. The upper end of the mounting plate is connected to the other end of the oil tank.

[0043] In this way, the fuel tank is positioned directly above the tank body, and is installed by connecting and fixing the mounting plate and support block to the mounting block. This makes the fuel tank layout more compact and the installation of the fuel tank more stable and reliable.

[0044] In the embodiment, the mounting block comprises a slanted section 10 at the lower end, which is arranged obliquely upwards and outwards, and the upper end of the slanted section is bent horizontally outwards to form a horizontal section 11.

[0045] In this way, the mounting block is simple and reasonable in structure design, and the mounting plate can be conveniently mounted and fixed.

[0046] Further, the mounting block, the supporting block and the box body are integrally formed.

[0047] Further, the mounting block and the supporting block are detachably connected together through connecting screws.

[0048] Further, a connecting rod is integrally arranged between the two mounting blocks.

[0049] In the embodiment, the muffler is arranged at one side of the oil tank, and the length direction of the muffler is arranged along the longitudinal direction of the oil tank; one end of the muffler is provided with a connecting port, and an exhaust connecting pipe 12 is connected to the connecting port; the other end of the muffler is connected to a connecting plate 13 arranged below the other end, and the connecting plate is fixed to one of the mounting blocks.

[0050] In this way, the muffler is arranged more reasonably, and the muffler can be conveniently arranged and installed, and is more stable and reliable after installation.

[0051] Further, the connecting plate is fixed to the mounting block through connecting screws.

[0052] In the embodiment, the air filter is arranged at one side above the cylinder head, and an air inlet connecting pipe 14 is connected to the cylinder head, and the distal end of the air inlet connecting pipe is arranged upwards and connected to the air filter.

[0053] In this way, the air filter, the muffler and the oil tank are arranged more reasonably in the horizontal direction, and the three components are more compact.

[0054] In the embodiment, a cylinder head cover 15 is arranged on the cylinder head; the oil tank is connected to an oil injection pump 17 on the box body through an oil pipeline 16, and the output port of the oil injection pump is connected to an oil injector on the cylinder head through an oil outlet pipeline 18.

[0055] In this way, the structure is simple and reasonable, and the connection between the components is more convenient.

[0056] Further, a scalding protection cover 19 is arranged outside the muffler.

[0057] In summary, the engine structure has the characteristics of simple and compact structure design, convenient installation and arrangement of each assembly, and improved installation stability of each assembly.
