Abstract

The invention discloses an engine, a lubricating system thereof and an engineering machine. The lubricating system of the engine comprises an oil pump and a speed ratio adjusting device. An input shaft of the speed ratio adjusting device is used for being connected with a power output shaft of the engine, an output shaft of the speed ratio adjusting device is connected with an input shaft of the oil pump, and a speed ratio adjusting end is arranged on the speed ratio adjusting device. The engine, the lubricating system and the engineering machine have the advantage that the pressure outputted by the oil pump of the lubricating system of the engine can be increased when the engine runs at an idle speed, so that the lubricating performance of the engine in an idle speed state is improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine lubricating system and an engine and engineering machinery provided with the engine lubricating system. Background technique [0002] When the engine is working, normal oil pressure must be maintained. Excessive oil pressure will destroy normal lubrication conditions, such as easy to damage oil seals and oil pipes, and consume engine power. Too low oil pressure will also destroy the lubricating conditions of the engine, resulting in poor lubrication, cooling and cleaning effects, which will cause adhesive wear of parts. [0003] At present, the speed ratio between the engine oil pump speed and the engine speed is fixed. The higher the engine speed, the higher the oil pump speed, and accordingly, the greater the oil pressure. When the engine is in an idle state, its speed is very low, and the speed of the oil pump is also very low, so that the oil pressure is relatively low, whi...
