How Does A Car Engine Work- Full Process Step By Step

Did you ever question yourself how does a car engine work? And got confusing answers? Then this article is just for you. Here I will describe briefly how to get power from petroleum and how does car engine works. You are going to find many interesting facts in this article. Hoping that this article will remove all of your confusion about the car engine. So let’s begin.

How Does Car Engine Work?

There are many cooking pots in the car engine, called cylinders, where the fuel is burned. These cylinders are made of solid metal and are sealed on all sides. But the cylinders can be open or closed on one side, as is the case with bicycle pumps. The cylinder has a very tight-fitting piston that can move up and down in the cylinder. Each cylinder has two valves or gates at the top, which can be turned on or off very quickly. The inlet valve supplies air and fuel to the cylinder from the carburetor (fuel injector). The outlet valve releases the ignited gases. At the top of the cylinder is a spark plug, which helps to ignite the fuel.

The bottom of the cylinder rotates on an axis called the crankshaft. This crankshaft starts rotating the gearbox, and the wheel starts turning from the gear. A typical car engine has at least 4 cylinders, but a car engine can have up to 6, 8, 12 cylinders: the more cylinders, the more powerful the car. Most cars or any vehicle today run on petroleum; batteries are an excellent idea but can’t give mileage like liquid fuel. Petroleum has a lot of energy, which is not available anywhere else.


The engine is almost perfect, but not perfect. Because some energy is expended in the step by step stage, from the cylinder to the wheel. Only 15-20 percent of your fuel is used for wheeled horses, and the remaining 60-65% is consumed somehow. I mean, if you pay 100 rupees for a petrol car, then only 15 rupees for a horse!


So this is the science and engineering behind car engines. Do you understand how to cross the road by filling the liquid fuel? Automobile engineering is not an easy task, yet I tried to describe it as simply as possible. If you still have a question or want me to tune in to the next one in more detail, be sure to let me know in the comments below. If you like the tune, be sure to share it with your friends!


How To Get Power From Petroleum?


Not just cars, but trucks, buses, trains, ships, Aeroplan’s – everything works on fuel made from petroleum. Petroleum is a thick, black, energy-rich liquid fuel that lies behind the Earth’s crust, and by fencing it off, we’re burning up huge fuel shortages. Petroleum is purified from the earth’s crust and converted into fuel liquids like petrol, kerosene, diesel, etc. Petroleum fuels are made from hydrocarbons; That means it contains most hydrogen and carbon atoms inside. Coal, paper, wood, etc., are also made up of hydrocarbons.

It is possible to burn the hydrocarbons in a fire and extract beneficial energy from there. During combustion, hydrogen, and carbon combine with air to produce carbon dioxide gas and water, generating heat. This process is called combustion, which releases a huge amount of energy. People have been generating energy for millions of years by burning hydrocarbons; this is how fire and the use of fire were discovered. But ordinary fires are much more inefficient, as well as a waste of energy.

Some Common Car Engine Layouts

There are many similar parts in neoteric engines. You will find combustion chambers, spark plugs, pistons, and more inside the modern engine. But based on the arrangement of those parts, engine layouts can differ significantly. Usually, car manufacturers choose the layout to think that they can fit properly in their car and intend the car to perform. Here, you are going to see some common car engine layouts. Keep reading.

Straight Or Inline Engine Layouts

All the engine cylinders are linearly arrayed in the straight engine, and the engine is situated parallel to the car’s length. It means it goes from the front of the engine bay to the back. This engine layout is sometimes called inline engine layouts.

Flat Or Boxer Engine Layouts

You may know the meaning of flat. This layout keeps the engine in a flat position as possible. This engine layout is also known as the boxer layout; the layouts’ cylinders are laid down flat in both directions. A flat or boxer type layout keeps the car centre, which makes the car easier to handle.

V Engine Layouts

It is not a flat layout nor straight layout. This layout has its cylinders arranged at an angle in a V-shape. This layout allows the car to fit more cylinders in a smaller place. And Having more power in a smaller area makes the V engine layout ideal for luxury high-performance vehicles.

What Do For Engine’s Better Performance?



A lot of energy is wasted when you cook something with a fire in a normal oven. The heat spreads in all directions, only a small amount of heat can go into the cooking utensils, and less heat enters the cooking. Car engines tend to be more efficient; it loses less energy and consumes more energy. The fuel is burned in a container in the car’s engine, then most of the heat from the fuel is converted into mechanical energy, and then the car starts moving to convert it into kinetic energy.
