Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of high-power air-start diesel engines, specifically relating to an external air-starting device for a high-power air-start diesel engine. Background Technology
[0002] Large-scale construction machinery is widely used in infrastructure, mining, transportation, and military industries. High-power air-start diesel engines are the main power source for large-scale construction machinery. The main starting method of high-power air-start diesel engines is air starting. In actual application, the original air starting system often encounters problems such as air cylinder damage and insufficient air cylinder pressure, which prevents the diesel engine from starting. Refilling or replacing the air cylinder wastes a lot of time. If an external air starting device is used, the above problems can be avoided. However, there is currently no external air starting device for high-power air-start diesel engines. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] This utility model proposes an external air starting device for a high-power air-start diesel engine to solve the technical problem of diesel engine failure to start due to damage to the original vehicle air cylinder or insufficient air cylinder pressure.
[0005] (II) Technical Solution
[0006] To address the aforementioned technical problems, this utility model proposes an external air starting device for a high-power air-start diesel engine. This device includes a high-pressure air cylinder, a high-pressure air hose, a universal quick connector, and a manual control valve. The output end of the high-pressure air cylinder, serving as the air source, is connected to the inlet of a high-pressure air hose. A universal quick connector is installed at the outlet of the high-pressure air hose, which is used to connect to the air starter of the diesel engine being started. A manual control valve is installed on the high-pressure air hose. By opening and closing the manual control valve, the high-pressure air cylinder supplies high-pressure gas to the diesel engine's air starter, thereby starting the diesel engine.
[0007] Furthermore, the external air starting device for the high-power air-start diesel engine includes two high-pressure air cylinders, and the output ends of the two high-pressure air cylinders are connected to the air inlet of a high-pressure air pipe.
[0008] Furthermore, the high-pressure air cylinders are made of carbon fiber.
[0009] Furthermore, the high-pressure air cylinder has a volume of 6.8L and a working pressure of 45MPa.
[0010] Furthermore, a pressure gauge is installed on the high-pressure air pipe to display the starting pressure.
[0011] (III) Beneficial Effects
[0012] This utility model proposes an external air starting device for a high-power air-start diesel engine, including a high-pressure air cylinder, a high-pressure air hose, a universal quick connector, a pressure gauge, and a manual control valve. When the original vehicle's air cylinder is damaged or the air cylinder pressure is insufficient, preventing the high-power air-start diesel engine from starting, the universal quick connector is connected to the air starter of the diesel engine to be started. The manual control valve is then opened, and the pressure gauge displays the starting pressure. High-pressure gas is then supplied to the diesel engine's air starter via the external air source from the high-pressure air cylinder, enabling the diesel engine to start normally.
