Mist lubrication system F · In two-stroke engines, the charge is compressed in the crankcase, and as such it is not suitable to have the lubricating oil in the sump. · Therefore, such engines are lubricated by adding 3% to 6% oil in the fuel tank itself. The oil and fuel mixture is inducted through the carburettor. · The fuel gets vaporized and the oil, in the form of mist, goes into the cylinder through the crankcase. · The oil that impinges the crankcase walls lubricates the main and connecting rod bearings, and the rest of the oil lubricates the piston, piston rings and cylinder.
· The main advantage with this system lies in the simplicity and low cost as the system does not require any oil pump, filter etc. What machine is it used for? · The mist lubrication system operates when the two-stroke engines · Mist lubrication systems which are used in machines are on the car engines. · Mist lubrication system usually needs on an engine to keep the engine perform as its high level possible. In simply for better performance.

Maintenance: · In terms of maintenance, the mist lubrication will cost low. · However it can have some serious damages which can lead to disadvantages while fixing. · This is not the best lubrication system out there. · While starting the engine is combust, some lubricating is also burnt and can cause a serious of major damages on the engine, · Another drawback would be, while lubricating the oil; it can produce acidic vapours during the combustion. This would lead to surface damage such as the parts of it inside can corrode away. Pressurized/Force Feed: Pressurized Lubrication: · Pressurized lubrication system is used in internal Combustion engines.
· At first the oil is forced by the oil pump from the crankcase to the main bearings and the camshaft bearings. · After that the holes drilled through the main crank shaft bearings journals. · Then the oil moves to the connecting rod. After all that work done then a pressure gauge is used to check the oil, if the oil is circulating inside the engines on the various parts. Draws oil from oil pan by means of oil pump. Pump forces oil through drilled and cast passages called oil galleries to crank and camshaft journals.
What machine is it used for? The common use of Force-feed/Pressurized Lubrication is in Internal Combustion Engines. In these systems, a pump forces oil into the engine and the bearings. If this pump stops workings or deteriorates, the engine will stop receiving oil and may suffer internal engine damage or engine failure. Pressurized/force-feed systems are manual. Maintenance: · The maintenance of a pressurized lubrication system is a difficult thing to do.
· Sometime it is important to check the engine regularly and check if the oil is working properly and if there is enough oil in the engine. · Some of the maintenance of pressurized lubrication is to change oil, checking the oil level, checking the oil quality or its condition, cleaning the filters, checking the spark plugs and see the cables and linkages lubricating properly. · The best way to check the engine is when the car is drives around 3000 miles. Then it would be ideal to check whole thing of the engine. Splash lubrication system Steps of working · The oil splashes inside the crankcase, over the cylinder and the piston. That is how it is call splash system lubrication. Supplies oil to moving by adding dippers to the bottom of the connecting rod.
Used primarily on small one cylinder engines. Splash lubrication is pretty primitive. A hook http://slideplayer.com/slide/5830279/ What machine is it used for? · Used in simple motors lawnmower’s, outboard boat engine and gear boxes.
· There is a reservoir of oil and as the gear/ bearing/ parts move through the oil the cause a fine spray of oil to spend over the rest of the parts. · They use oil with a higher viscosity. They are usually in a closed system. Maintenance: · Maintaining the combination of splash and pressurized system is all the same thing as how we would maintain the splash and pressurized system separately. · Some maintenance is to change oil, checking the oil level and cleaning the air filters. ·
