The invention belongs to the technical field of engines, and provides an engine starting system, a starting method and a lubricating oil way cleaning method. In the lubricating oil way cleaning method, an engine adopts a pre-supply oil pump to flush a lubricating oil way, and after lubricating oil in a main oil way reaches a certain pressure, the engine is made to rotate at a low speed through a turning mechanism, all parts of the whole lubricating oil way can be flushed conveniently, particles in the lubricating oil way can be flushed out conveniently, and the car flushing effect is improved.According to the starting method, before the engine is started, the pre-supply engine oil pump is adopted for oil supply and pre-lubrication, after lubricating oil in the main oil way reaches a certain pressure, the engine is made to rotate at a low speed through the turning mechanism, the lubricating oil can cover the whole bearing, especially a bearing area, and after the set pressure is reached, the engine is started again; the lubricating state of a key bearing in the starting stage is enhanced, and starting abrasion is reduced. The vehicle flushing and starting process is automatically controlled, and the workload of people is reduced.
Description
technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine starting system. The invention also relates to an engine, a starting method and a lubricating oil passage cleaning method. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] In the existing technical solutions, for large-bore engines, especially large-bore diesel engines, static flushing is often used for flushing (flushing the lubricating oil circuit of the engine). After flushing for a period of time, the engine is manually cranked, and then static flushing is performed until The time required to complete the flush. Although the flushing of the lubricating oil circuit of the engine has been considered, it needs to be manually rotated regularly, which is time-consuming and laborious. [0004] The existing starting technology scheme provides a certain...
