Forced lubricating system of single cylinder diesel

Abstract

The invention discloses a forced lubricating system of a single cylinder diesel. The forced lubricating system comprises an oil sump and an oil pump, wherein the oil sump is used for storing oil and cooling, the oil pump is arranged in a gear chamber cover, the oil sump is internally provided with an oil strainer, the oil is sucked by the oil pump through the oil strainer, an outlet of the oil pump is connected with an oil filter, the oil which is filtered by the oil filter can be respectively and forcedly delivered to an oil spray pump assembly, an air cylinder cover assembly and an engine body assembly after entering into an oil duct in an engine body, and oil return ports of the oil spray pump assembly, the air cylinder cover assembly and the engine body assembly are all communicated with the oil sump. According to the forced lubricating system disclosed by the invention, clear, full and forced circulating lubrication of the oil in the diesel is realized through the action of the oil pump and the oil filter, the phenomena of untimely abrasion, bearing bush hugging, cylinder scuffing and the like, which are caused by existing splash lubrication, of each moving piece of the diesel are overcome, the lubrication oil loss of a transmission gear set is avoided, the gear mesh noise and the oil temperature are reduced, the abrasion resistance of each moving piece is increased, and the service life of each moving piece is prolonged.

Description

technical field [0001] The invention relates to the technical field of single-cylinder diesel engines, in particular to a forced lubrication system for single-cylinder diesel engines. Background technique [0002] The diesel engine lubrication system is a very critical system. Because of its simple structure, the single-cylinder diesel engine mostly adopts the splash lubrication method. It rotates and stirs the oil through the gears and moving parts in the body to form oil mist to lubricate the piston, piston ring and cylinder liner; Lead the engine oil to the crankshaft journal to form an oil film to lubricate the crankshaft journal and connecting rod bearings, and connect the oil pipe through the camshaft hole of the main bearing seat to squeeze the lubricating oil from the spiral groove to the oil hole of the cylinder head cover for oil dripping when the camshaft rotates. Lubricate valve housing components. Although this traditional lubrication method can send lubricati...

AI Technical Summary

Problems solved by technology

Although this traditional lubrication method can send lubricating oil to the friction surfaces of the diesel engine, the lubricating effect is not very sufficient, and it is easy to cause premature wear of cylinder liners, pistons, piston rings, connecting rod bearing bushes, crankshaft journals, etc., seriously It will cause tile holding and cylinder pulling, and it will easily cause the transmission gear set to lose oil due to lubrication.
