Description

Technical Field

[0001] The utility model relates to the technical field of loader accessories processing, in particular to a loader starting auxiliary device in an ultra-low temperature environment. Background Art

[0002] In extremely cold and low-temperature areas, especially when the temperature is below minus 30 degrees Celsius, cold starting of loaders becomes a huge challenge. Faced with such an environment, loaders are often difficult to start smoothly, causing considerable trouble for drivers and operators. In order to solve this problem, people sometimes try to start the loader through some special methods, such as removing the pipeline behind the air filter, spraying ether and other combustion aids directly into the intake manifold multiple times, and igniting multiple times to force starting. However, this starting method is not a long-term solution and there are many problems and risks.

[0003] First, continuous and frequent ignition in a low temperature environment will greatly consume the battery power of the vehicle. In most cases, the battery power of the vehicle has been consumed to the point where it cannot drive the starter before the engine is successfully started. This requires reliance on an external power supply for auxiliary starting, which further increases the complexity and risk of the operation. Secondly, frequent and repeated starting attempts will not only cause the starter to overheat, but may even cause damage to the starter. The starter is a key component in the loader starting process. Once it is overheated or damaged, it will directly affect the normal starting and operation of the loader.

[0004] Therefore, facing the problem of loader starting in low temperature environment, we need to find a more reasonable and effective solution. Utility Model Content
