Organic Chemistry The first law of thermodynamics relates the work done on or by a system and the heat flowing into or out of it to the resulting change in its internal energy as 62 This is nothing more than a statement that energy is conserved. The sign conventions are that positive heat flows into the system and positive work is done by the system.

Consider the oil as the lifeblood of your engine. Without it, you can almost as certainly say goodbye to your ride or a myriad of expenses having the engine repaired or worse, replaced. Here are some of the more common reasons why engine oil is important. Prevents friction This is inarguably the most important reason why you need to put the right kind of oil into your engine.

Just look at it this way. Imagine your knee as the engine and the synovial fluid inside your knee joint as the oil. Now try removing the synovial fluid from your joint and you can actually hear your bones grinding together.

You will also not be able to move because it will be very painful. While the engine is not a joint, it is essentially made up of moving parts. You are looking at a multitude of metallic parts that can easily heat up because of friction.

As such, the primary purpose of engine oils is to lubricate these moving components including the various mechanisms that are responsible for their activities to help eliminate friction. And you already know that whenever friction is involved, heat is also present.

This is one reason the term fry an engine came about. Preventing friction between these moving metallic parts will help prevent them from grinding against each other, helping avoid damage to the components, and saving you from potentially costly repairs.

In worst cases, you might be better off getting a new car. Channels heat away from combustion cycle This is a natural consequence of the prevention of friction. It is inadvertent that heat will still be generated because of the movement of these individual metallic parts.

The good thing is that the oil also serves as an insulator so that any heat generated by these moving parts will not affect the combustion cycle.

We know that the primary purpose of the engine is to produce highly controlled explosions or combustion inside its cylinders. Now, if extraneous heat were applied into these controlled explosions, you can just imagine how problematic it will be for the engine.

Acts as a magnet for combustion byproducts The fuel that enters our engine through the fuel injection system or even the carburetor in older car models is essentially composed of chemicals that, when ignited to create the controlled explosions we have come to associate with car engines, can produce chemical byproducts because of the resulting chemical reaction.

This is where engine oil can help. Since these types of fluids are slick and highly viscous, they have the capability to attract and suspend all the unwanted byproducts of combustion.

For example, engine oil can put acids and silicon oxide into a thick suspension so that these will not go into the other parts of the engine and cause unwanted damage.

Minimizes oxidation We know that fuel has to be mixed with air to produce combustion. And you know what air contains? And whenever there is oxygen, the chemical process of oxidation is not far behind.

Can you imagine the internal combustion engine showing signs of corrosion everywhere? While we cannot stop oxygen from entering the engine remember, we cannot screen oxygen from the other gases entering our air intake we can, at least, minimize its oxidative effects by using the right engine oil.Learn more about Chemistry Electronics, Biology, Microscopy (Microscope), Amateur Radio, Photography, Radio Astronomy, Science, Home Learning and much more.

About BioSurplus Your equipment shouldn’t be a barrier to your work, but rather an engine that drives research forward. At BioSurplus, we provide valuable, quality used lab equipment at attractive prices to help power research and innovation. If you love your car, then you know just how important its engine is.

Taking good care of the car’s engine is a must and an inherent responsibility for every individual who owns a vehicle. And one of the best ways to care for your car’s engine is by using only the highest possible quality [ ]. The engine you are to experiment is a real heat engine that can be taken through a four stage expansion and compression cycle to do useful mechanical work by lifting small masses (apples).
