The parts that oil always passes in any engine are usually focused on the moving parts, not the static parts. The lubrication system of any engine is designed to send enough volume of oil to all the moving parts of the engine once the engine is in operation. Basically, a typical car engine will have oil flow in a pattern like from the sump, a reservoir under the crankcase , it is drawn through a wire strainer into the pump.

Most pumps have an output of several gallons per minute and can produce pressures of more than 60psi. From the pump, oil will be made to pass through the filter and into the main gallery drilled in the side of the crankcase. Drillings connect the gallery to the crankshaft main bearing housings such that once the engine is running oil will be forced under pressure between the rotating crankshaft journals and the bearings.

The oil supplied to the main bearing to link to the big-end bearings at the shaft base where the connecting rods are fixed such that the arrangement makes it possible for all the bearings located on the crankshaft to be pressure-fed with oil.

When the oil gets to the base of the connecting through the actions of the crankshaft, the oil will be taken from there. The rod may be drilled near its base so that a jet More of oil sprays the cylinder walls and the underside of the piston as the crankshaft rotates. Alternatively, the connecting rod may be drilled along its length so that pressurized oil from the big-end bearing is taken directly to the gudgeon pin to lubricate it. The camshaft operates at half engine speed, but it needs effective lubrication because of the high rubbing loads on the cams.

It is usual to pressure-feed the camshaft bearings and to splash or spray oil on the cam lobes. A push-rod engine with its camshaft mounted low in the crankcase has oil piped to the hollow rocker shaft, from where it lubricates the rocker bearings and push-rod ends. The excess oil will drip down the push-rod openings and coats the camshaft lobes on its way back to the sump. For engines with overhead camshaft, two systems are popular and the simplest among them is the rotating of the camshaft lobes dip into a trough of oil.

An alternative way is to spray the cam lobes with oil. This is usually done by a perforated oil pipe alongside the camshaft. Currently, he is working in the sheet metal industry as a designer.

So the rubbing part requires that some substance should be introduced between the rubbing surfaces in order to decrease the frictional force between them.

Automotive engine lubrication basics of investing A typical engine oil is carefully formulated to protect the valve train, the bearings and the piston assembly, despite the different lubrication requirements of these components. Table of Contents. Physicists are developing better oils and lubricants that promise to improve the fuel efficiency of cars and reduce greenhouse-gas emissions. Hydraulic oils are known in the market as hydraulic fluids or hydraulic liquids as well. Essentially, the ratio of shear stress to shear rate - the viscosity - remained constant at all shear rates.

In higher temperatures, thick oils maintain oil pressure and film strength, and support heavier loads. The way in which it varies with temperature, shear rate and pressure determines to a great extent how the lubricant performs in an engine. Most engine manufacturers design their components to operate with oils and greases within a certain viscosity range. Lubrita supply customers worldwide from biggest European ports!

It's the lubrication system's way of saying, "Settle down, kids. Oil filter: While Oliver and his friends are allowed to pass into the engine, the filter stops any dirt and debris the oil may have picked up on its last pass through the system. Spurt holes and galleries: Oliver giggles every time he says "spurt holes.

These are the little holes drilled in the crankshaft or other parts of the system that allow the oil to coat the bearings and cylinders that need to stay lubricated. Sump: After doing his job to keep the moving parts of the engine moving, an exhausted Oliver slides all the way down into the oil pan again, also known as the sump, to hang out until he's sucked back up the pickup tube -- and he's back on the job.

There are basically two types of oil systems in vehicles, both of which sound like types of walruses or something: wet sump and dry sump. Most cars use a wet sump system. The more you say it, the weirder it sounds. Wet sump. That means the oil pan is at the bottom of the engine , and the oil is stored there. Remember Oliver the oil molecule's lounge? It's kind of like he has a table next to the dance floor at the club. And in this strange metaphor, the dancers are pistons and bearings.

The advantage of a wet sump system is its simplicity. The oil is close to where it will be used, there aren't too many parts to engineer or repair, and it's relatively cheap to build into a car. Some cars, especially high-performance cars, use a dry sump system. That means the sump isn't underneath the engine -- in fact, it can be located anywhere within the engine compartment.

After Oliver does his job in the engine, he doesn't just drip into the lounge. He goes to the VIP room away from the dance floor. A dry sump system gets you a couple of bonuses: First, it means the engine can sit a little lower, which gives the car a lower center of gravity and improves stability at speed. Second, it keeps extra oil from soaking the crankshaft, which can lower horsepower. And, since the sump can be located anywhere, it can also be any size and shape.

Two-stroke engines , by the way, use a completely different type of technology. Scooters, lawn mowers and other two-stroke machines have the oil mixed right in with the gasoline. When the gasoline evaporates in the combustion process, the oil is left behind to do its slick business. Sometimes you have to do this yourself, measuring the correct amounts before filling the tank.

But sometimes, as in most motor scooters, there's an injection system that takes oil from the reservoir and mixes it with the gasoline for you in just the right proportions. Like lots of automotive journalists, I thought I knew exactly how the lubrication system worked. 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!

How an Engine Lubrication System Works. Engine Lubrication System: When two metallic surfaces under direct contact move over each other, they create friction which generates heat.

This causes excessive wear and tear of those moving parts. However, when a film of …. Published on: November 24, When two metallic surfaces under direct contact move over each other, they create friction which generates heat. However, when a film of lubricating matter separates them from each other, they do not come in physical contact with each other. Thus, lubrication is a process that separates the moving parts by supplying a flow of a lubricating substance between them.

The lubricant could be liquid, gas or solid. However, engine lubrication system mainly uses liquid lubricants. There are mainly four types of lubrication systems used in automotive engines which are:. It stores the engine oil and then circulates it within the engine.

Oil sump sits below the crankcase and stores the engine oil when the engine is not running. It is located at the bottom of the engine in order to collect and store the engine oil. The sump guard absorbs the hit from the uneven road and protects the sump from any damage. An Oil Pump is a device which helps to circulate the lubricant oil to all the moving parts inside the engine. It is generally located at the bottom of the crankcase, close to the oil sump.

The oil pump supplies the oil to oil filter which filters and sends it onward. The oil then reaches different moving parts of the engine through oil galleries. Even, small particles can choke the oil pump and galleries. If oil Pump gets blocked, then it can cause the severe damage to the engine or even complete seizure of the engine. To avoid it, the oil pump consists of a strainer and a by-pass valve.

Hence, it is necessary to change the engine oil and filter at regular intervals as recommended by the manufacturers. In order to get better performance and longer engine life, it is essential that the engine oil quickly reaches the moving parts of the engine. For this purpose, manufacturers provide oil galleries within the engine. The Oil Galleries are nothing but series of interconnected passages which supply the oil to the remotest parts of the engine.

Oil galleries consist of big and small passages drilled inside the cylinder block. The bigger passages connect to the smaller passages and supply the engine oil upto the cylinder head and overhead camshafts. The Oil Cooler is a device which works just like a radiator.
