[0002] As a power generating device, the engine can convert other forms of energy into mechanical energy. In order to facilitate the operator to control the engine, the existing general engine includes an operating unit for controlling the start and stop of the engine. Since the two-cylinder engine has excellent performance in combustion efficiency, it is widely used in various industries.

[0003] For example, Chinese patent document CN113825899B discloses an internal combustion engine, which has a first fuel pump that draws fuel through a fuel filter and a second fuel pump that supplies fuel to a fuel injection device, and includes: a first fuel piping that connects the fuel filter with the first fuel pump and the second fuel pump, and the second fuel pump is set to a high pressure compared to the pressure of the first fuel pump; and a second fuel piping that connects the second fuel pump with the fuel injection device, and the fuel injection device injects fuel into a combustion chamber formed in a cylinder portion of the internal combustion engine. A shielding wall that covers the outside of the cylinder portion is provided between at least a portion of the second fuel piping and the cylinder portion, and the shielding wall has a retaining portion that retains at least the first fuel piping and the second fuel piping.

[0004] For another example, Chinese patent document CN212473347U discloses an engine control box, including a box body connected to the engine housing, on which a voltage regulator, an isolator and / or an alarm light and / or a start switch and / or a damper switch are centrally arranged. When in use, a plurality of control components are first assembled centrally on the control box, and then the control box is assembled on the engine. This extremely simple solution cleverly solves the problem that the wiring on the engine is messy and the installation, replacement, and maintenance of the engine and its components are extremely inconvenient. The engine control box provided by the utility model not only makes the structure of the engine periphery more compact and the space more spacious, but also reduces the difficulty of assembling the control components and improves the assembly efficiency. The prior art solves the structural arrangement of the voltage regulator, isolator, damper switch, and start switch, but there are problems such as large space occupation and inconvenient operation.

On the one hand, it can shorten the length of the control harness of the start-stop control device, which can reduce the use of consumables and the storage space of the control harness. On the other hand, it can make full use of the characteristics of the V-shaped structure of the two-cylinder engine and the space on the upper part of the air guide cover. The structure is compact and can reduce the space occupied by the engine.

[0007] Preferably, the start-stop control device is arranged not to exceed the side contour line of the first wall of the air guide housing. In this solution, it can be ensured that the start-stop control device does not occupy the circumferential space, making the overall structure more compact.

[0008] Preferably, the start-stop control device is arranged on the right side of the machine body. In this solution, the start-stop control device is arranged on the right side for more convenient operation by the user.

[0009] Preferably, a mounting seat is provided on the cylinder located on the right side of the machine body, and the start-stop control device is installed on the mounting seat. In this solution, the arrangement of the mounting seat can make the overall structure more compact and reliable.

[0010] Preferably, the mounting seat is provided with a lifting hole for lifting the machine body. In this solution, the start-up control mounting seat is used as the lifting hole, avoiding the use of a separate mounting seat, saving costs and simplifying the assembly process.

[0011] Preferably, the start-stop control device includes an electric start switch, a throttle switch and a damper switch.

[0012] Preferably, a throttle control assembly is also provided on the machine body, the throttle switch is connected to the throttle control assembly via a throttle cable, and the throttle switch is connected to the throttle control assembly via a throttle cable.

[0013] The utility model has the following beneficial effects: the utility model fully utilizes the space on the upper part of the air guide cover shell, has a compact structure, can reduce the space occupied by the engine, and shortens the length of the control harness of the start-stop control device; it can also save costs and simplify the assembly process.
