Car engine: principle of operation that you need to know!

When you sit in your car seat and press button to start, is it surprising to hear sound of a friction motor that makes you feel like power of whole world is under your feet?

So, today let's find out how a car engine works! A car engine usually uses a four-stroke four-cylinder engine, necessary understanding limits our capabilities today, so we will focus on this car engine. Four-stroke four-cylinder engines have some complexity, but basic principles are intuitive, as follows:

The first stroke is "suction stroke". During this time, intake valve in cylinder opens, piston moves down, and fresh air is “sucked in” from this intake valve and part of gasoline is “sucked out” at same time.

The second measure is called "compression measure". In this case, all doors in cylinder are closed, and piston compresses previously drawn gases (air and gasoline) upwards. Gasoline is compressed in cylinder, forming flammable gases. This process involves countless troubleshooting and car engine repairs.

The third stroke is "ignition stroke". During this process, combustible gases in cylinder ignite, creating an explosion that pushes piston down and cranks crankshaft. This process actually provides energy that powers your car.

Finally, return piston moves up, pushing exhaust gases out of cylinder through intake valve. It is worth noting that the above ideas are of a very theoretical nature. In fact, these processes occur simultaneously, and automotive engine designers must optimize this process for maximum efficiency.

The above is a brief introduction to how an automobile engine works. I hope it will help you and deepen your knowledge about cars.
