lubrication of two stroke gasoline engine

There was friction parts mutual movement, which decrease the temperature of friction and wear of parts and reduce the friction power loss, all need lubrication.Between cylinder and piston to produce a burning, high temperature, lubrication is more required.Crankcase preloading scavenging type two-stroke machine, crankcase is the cylinder closed sometimes, but sometimes will.Sweep the airway open, there are scavenging air high-speed flow, as long as the crankcase entities product oil, instantly blown into the cylinder.Will cause a small amount of lubricating oil into the cylinder gasoline engine smoke, and speed up the carbon deposit, a large amount of oil into the cylinder can make spark plug ignition, causing gasoline engine stalled.Two-stroke machine lubrication, and there is no too much oil into the cylinder, must adopt special lubrication method, and the use of special oil sawing ShuaiJia gasoline engine is mixed lubrication mixture fuel through the carburetor atomized particles, crankcase compression, gasoline vaporization, gradually melts in soluble in gasoline engine oil into smaller particles, part of the suspension in the gas, incomplete combustion through out of the cylinder, the back part of the adhesion on sports played the lubrication and friction surface oil adhesion on the friction surface oil by air blowing, some splash, the rest along the wall gradually slip into the cylinder, in addition to the cylinder, piston group has a role in lubrication, and seven airflow spray scattered.Under various conditions, the gasoline engine is 35:1 plead for the requirement of the engine oil consumption, medium speed about 50:1
