    Abstract: An inverted non-stop apparatus of a multi-cylinder diesel engine for a free-fall lifeboat is provided. The apparatus includes a lubricating system and a breathing system. The lubricating system includes a machine body (101), an engine oil pump, and an oil pan (118). The breathing system is a diesel engine breather. A partition board (1181) is transversely provided in the oil pan (118) to divide a cavity of the oil pan (118) into a left cavity and a right cavity. The left cavity is an oil collection groove (1182), and the right cavity is an oil tank body (127A). A flange is provided at an opening of the oil tank body (127A) for fixing an oil tank cover (125) to form an enclosed lubricating oil tank (127). The engine oil pump is a double pump having oil inlets and outlets independent separately, which is formed by superposing upper and lower layers, wherein the upper layer is a lubricating pump (111) and the lower layer is an oil return pump (112). An oil suction port (114) of the oil return pump (112) is connected to the bottom of the oil collection groove (1182), and an oil outlet is connected to the lubricating oil tank (127). An oil inlet of the lubricating pump is connected to the lubricating oil tank (127), and an oil outlet is communicated with a main oil path (102) of the machine body. A breathing one-way valve (132) and an air pressure relief valve (131) are provided on the oil tank cover (125). The inverted non-stop apparatus of a multi-cylinder diesel engine for a free-fall lifeboat separate an engine oil collection function and an engine oil storage function borne by an oil pan of a diesel engine, so that no matter the diesel engine is longitudinally and transversely turned over and inverted, the diesel engine can operate normally.
