There is one thing you will notice under the bonnet of a modern car that is use of plastics over engine. But why every single car has these plastic engine covers? Why do car manufacturers bother to spend extra time and money to make them?We will answer all these questions in this article.
Under the plastic cover we have fuel lines,spark plugs,fuel injectors,alternator and many other mechanical components.Plastic cover is used with engine to serve following purpose:
1.) A plastic engine cover hides wires and fuel lines, while making them still quite easily accessible. A nicely dressed engine bay typically means that some components can be hard to reach for repair. When you have a big piece of plastic hiding everything, you don’t have to worry about the looks – it is the cheapest way to keep the engine bay looking tidy. This is equivalent to cleaning the mess off of your desk straight into the drawer – out of sight, out of mind.
2.) It provides good insulation that gives a cooler surface that are safer for the general person to interact with. This also helps keep the bonnet cooler.
3.) Plastic engine covers can be heat-resistant and absorb vibrations, making the sound of the engine just that little bit quieter.
4.) Cover keeps fluids below the cover. In a car with high speeds, usually more oil splatter and coolant being thrown around, up on the hood, etc. If you take cover off, you would find some oil, grease and/or dried coolant under it.
5.)Plastics are easily manufactured to cover the complex engine shape, light weight and are inexpensive.
So,these are the reasons for the use of plastic cover over engine. It is likely that in the future, engines are going to be tucked away even more and not accessible without specialized equipment.
