Learn About Engine Internal Parts With Easy Mechanics

Today we present to you the second episode of our new program, Easy Mechanics, to introduce you to the components of the car’s engine or what we call the engine internal parts.

After our colleagues Karim Deeb introduced in the first episode last Monday, the different types of engines, today we will inform you dear Arab GT followers, about what is inside the beating heart of your cars, the parts you find inside the engine block.

Watch The Video:

The car engine block is made of hard materials that can withstand high temperature and pressure. In the past, it was made of iron (there are some companies that still use iron), But nowadays most of car-manufacturers use aluminum because it is much lighter and it can withstand very high temperatures.

The internal parts of the engine block:

  • The cylinders, their numbers vary according to the type of engine.
  • The pistons or the “engine pistons”
  • The piston rings, which are available in two types; The top two rings— known as compression rings— are primarily for sealing the combustion chamber and achieving the ideal temperature in the combustion chamber, and the bottom ring— known as the oil control ring— is primarily for controlling the supply of oil to the cylinder wall, in order to lubricate the piston skirt
  • The connecting rods which connect the piston to the crankshaft.
  • The crankshaft, which is a rotating shaft usually made from metal, or forged steel. A flywheel is often attached to one end of the crankshaft to transfer power to the transmission and then to the wheels. While a Harmonic damper is attached to the other end of a crankshaft in order to reduce torsional vibration.


We hope to have provided you, dear Arab GT followers, with useful and simplified information within today’s episode of  Easy Mechanics program,  in the next episode, God willing, we will talk about the components of cylinder heads
