Petro-oil lubrication system

• In this method of lubrication system, the lubricating oil is mixed with the petrol and fed in to the engine cylinder during the suction stroke. The droplets of the partials cause the lubricating effect in the engine cylinder. This method of lubrication is used in small engines like motorcycles and scooters. This method is not much effective in large engines.
• The system of lubrication is used in scooters and motor cycles, particularly for two stroke engines about 3 to 6% of lubrication oil is added with petrol is the petrol tank. The petrol evaporates when the engine is working. The lubricating oil is left behind in the form of mist. The parts of the engine such as piston, cylinder walls and connecting rod are lubricated by being waited with the oil mist left behind.
• When the added oil is less, there will be insufficient lubrication and even result in seizure of the engine. If the added oil is more, it will lead to excess exhaust smoke and carbon deposits in the cylinder exhaust port and spark plugs.
