How the Parts of an Engine Lubrication System Work

The lubrication system in an engine performs the function of reducing wear and tear and ensuring smooth functioning of the moving parts of the engine.

Why is a lubrication system needed?
When different working components, for example, parts of an engine move while working, they constantly rub against each other. A direct consequence of this is wear and tear of these parts. Other consequences are performance speed and noise. Imagine a number of strong metal parts inside an engine rubbing against each other continuously at high speed. They create a lot of noise. Apart from the noise, since there is friction, which in other words is resistance, a lot of energy is wasted on the extra effort needed in the working of these moving parts.

What a lubrication system does
An engine lubrication system performs three important functions

Lubrication oil decreases engine wear by occupying the space in between the moving components like bearings shafts etc. Thus, the moving parts of the engine do not come into contact directly, but move on a layer of lubricating oil between them. This saves a lot of power in the engine system as a whole.

When engine parts move, they produce heat due to friction. This heat has to be removed for proper functioning of the engine. The lubricant oil receives this heat and goes back to the oil pan where it is cooled. Some engines also spray oil on the back of the piston, which thus cools it.

The oil seals the area between the walls of the cylinder and piston rings. This reduces the leakage of gases from the combustion cylinder of the engine

Parts of an engine lubrication system

  • Oil Pump: The gear type of oil pump has a pair of gears. The space between the gears are filled with oil. This oil pump sends oil through the filters to the main bearings and other parts. Main bearings and rod bearings are lubricated enough to perform their functions in an adequate manner. In the rotor oil pump type, there is an inner and outer rotor. As the inner rotor is driven, it drives the outer rotor, forming gaps in between them for the oil to pass through. As the oil which enters the rotors is already is under pressure, it is forced into the outlet.
  • Oil Pan: Oil also flows through the grilled holes and flows into the cylinder head lubricating the galleries, it then returns to the oil pan from where it was taken.
  • Oil Cooler: Oil cooler is a system which prevents excess-heating of lubricant oil. For this, oil is circulated through lines that carry hot oil.

Things to Know About an Emergency Brake

When you are learning to drive, you will have some idea about almost all the components and controls that are directly involved in the working of a car. This may include, the steering mechanism, acceleration, transmission and braking. When you finish learning and become a driver, these separate mechanisms will simply function in your mind as a single unit through intuition. But, there is a component that does not easily fit into your driving intuition without exclusive study and thought about it. It is the emergency braking system in a car. It is different in functionality than other mechanisms of a vehicle because, it technically overrides the braking system in the car and has the lowest regard for the nature and the possible processes the other working components may be in. In other words, the emergency brake, does not ‘work’ with the vehicle as a whole, but stands alone only to be used in emergency situations. So, a little care needs to be taken in selectively learning how an emergency brake works and how to handle it in different situations.

Facts to keep in mind about an emergency braking system:

  • Using the emergency brake other than emergency situations will severely damage the braking system. So, if it happens, check your brake discs and other parts of the braking system to make sure everything is fine.
  • The emergency brake can be used as a parking brake. While parking in an uphill position, make sure to activate your parking brake.
  • In automatic transmission vehicles, it is better to set the emergency brake before you release the service brake pedal. This will help to keep the vehicle’s weight off the transmission gears.
  • It is possible that one can forget that the emergency brake is on. To avoid riding off with the emergency brake on, tighten it as hard as possible.
  • In some vehicles, the emergency brakes engage the front wheels and not the back. So, before using an emergency brake, make sure the kind of mechanism that is involved.
  • Always remember, using an emergency brake in a brake failure, is not a perfectly safe option. It is only a counter-measure, and a last resort to stop the vehicle.
  • To use the emergency brake in a brake failure while riding, one should have a deep understanding of car dynamics, road conditions and a quick grasp of the surrounding. Because, as much as an emergency brake can stop the car, at high speeds, it may fishtail, lockup or skid making you lose all control of it.
  • It is best to keep the emergency brake under check always. This is because, brake wires might disengage in case of rusting. This is dangerous as it happens unexpectedly, and when you need it the most.
