The oil mist is generated in the generator by moving the dry air through a venturi. It will make a low-pressure area and the oil will be siphoned from the reservoir. The oil enters the distribution network because it is an atomized form. There should be sufficient pressure in the distribution header to impart a velocity to the oil mist. At the oil mist, distribution manifold flow is laminar will be changed to turbulent flow through the distribution channel.
The oil mist is injected into the bearing housing for bearing lubrication and the manifold is used to collect the coalesced oil particles from the drop points. In the wet sump system, an oil pan is present at the crankcase, sump from which the lubricating oil is pumped to various engine components by a pump.
After lubricating these parts, the oil Bows back to the sump by gravity. It is collected up by a pump and circulated through the engine lubricating system. The strainer is a fine mesh screen that prevents foreign particles from entering the oil circulating systems. A pressure relief valve is provided which automatically keeps the delivery pressure constant and can be set to High value.
When the oil pressure exceeds that for which the valve is set, the valve opens and allows some of the oil to return to the sump thereby relieving the oil pressure in the systems.
Most of the oil from the pump goes directly to the engine bearings and a portion of the oil passes through a cartridge filter which removes the fluid particles from the oil. This reduces the amount of contamination from carbon dust and other impurities present in the oil. Since all the oil coming from the pump does not pass directly through the filter. The advantage of Wet sump lubrication system is that clogged filters will not restrict the flow of oil to the engine.
Light-duty engines use this type of lubrication system. But when I had to actually write it down, listing each part and how the oil moved through the engine, I realized I only had the vaguest idea of how it all went down.
I'm also guilty of talking about wet sump and dry sump systems as if I had a clue. Now that I do have a clue, thanks to my research for this piece, I'll be even more insufferable. The one thing I did know for sure was that bit about two-stroke engines and mixing the oil with the gasoline. I'm the proud owner of a two-stroke cc scooter with an injection system, so I don't have to premix. Now if I could only find a sidecar for the dog Sign up for our Newsletter!

Other Systems. How an Engine Lubrication System Works. You may know the basics, but do you really know exactly how your car's lubrication system works, where the oil goes and what it's actually oiling? See more pictures of car engines. Engine Lubrication System Technology " ". There are two types of oil systems in vehicles: wet sump and dry sump. What are the components of a lubrication system?
Oil pan, pickup tube, oil pump, pressure relief valve, oil filter, spurt holes and galleries, and sump. Why is lubrication important in the engine? A well-oiled engine allows the vehicle to run on less fuel at a lower temperature with less effort. All of this means less wear and tear on the moving engine parts, which can ideally save you money in the long run.
What is the purpose of lubrication in engines? To create less friction and make the vehicle run better. How are two-stroke engines lubricated? Is anyone developing lifetime engine oil?
What's new in synthetic oil technology? This reduces the amount of current flowing in the circuit. The indicating unit consists of two coils that balance the movement of the pointer on a scale, in a manner similar to the electrically operated fuel gauge. The metal thermostat type oil pressure indicator is similar to the bimetal thermostat furl gauge. It consists of an engine unit and a dash unit. The oil pressure on a diaphragm distorts the engine unit thermostat blade, and this distortion produces a similar distortion in the dash unit thermostat blade, causing the oil pressure to indicate on the dial.
In many motor vehicles, the engine oil pressure is indicated by a warning light. The light comes when the ignition switch is turned on and the oil pressure is low. The circuit user four-stage diaphragm switch which operates a warning a lamp according to the oil pressure required for different engine feeds.
Fig shows an oil pressure warning lamp with a four-stage diaphragm operated switch. When the oil exerts pressure on the diaphragm the projection attached to it presses the uppermost contact bar, breaking the contact between the two projection further movement of the diaphragm deflects the second bar, and so on up to the fourth stage. Each of these four stages is brought into a circuit with the warning lamp by a selector switch operated in conjunction with the speed-o-meter.
In this way, the warning lights up only when the oil pressure falls below the value corresponding to the minimum engine speed. Email Address. Saif M.
