Abstract

The invention relates to the technical field of engines, in particular to a cold start auxiliary device and an engine. The cold start auxiliary device comprises a shell, an adjusting assembly, an elastic piece and an ejector rod; the shell is connected to an engine and provided with an oil passing cavity, the cavity wall of the oil passing cavity is provided with a first limit in a protruding mode, the shell is provided with an oil inlet and an oil return opening which are communicated with the oil passing cavity, the first limit is located between the oil inlet and the oil return opening, the oil inlet is connected to a main oil way of the engine, and the oil return opening is communicated with an oil pan of the engine. The adjusting assembly is arranged at one end of the oil passing cavity. The elastic piece is arranged on the adjusting assembly and located in the oil passing cavity. According to the cold start auxiliary device, the problem that cold start of a diesel engine is difficult in winter is solved, the maximum oil quantity of an oil pump of the diesel engine is limited, the structure is simple, reliability is high, manual operation is not needed, and the cold start auxiliary device is safer, convenient and easy to achieve.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a cold start auxiliary device and an engine. Background technique [0002] In the prior art, a starting oil quantity limit switch is added at the fuel injection pump rack at the front end of the engine. When starting, the limit switch is manually turned to the starting fuel quantity state to improve the starting performance of the diesel engine. Then turn the fuel limit switch back to the normal state to prevent the power of the diesel engine from being affected. This switch needs someone to operate beside the diesel engine every time the diesel engine is started, which increases the workload. There is a potential safety hazard when the diesel engine is started. In another prior art, a smoke limiter is added to the rack at the front end of the oil pump. Although unmanned operation is realized, the structure of the smoke limiter is complex and the failure rate is high. SUMMARY ...
