Basic Engine Topics are going to include all engine parts and operations.

So, Basic engine parts are usually referred to as:

  • Bottom end
  • Top end
  • Front end
  • Oil pan
  • Valve cover
  • Front cover

Parts like crankshafts, bearings, pistons, rings, cams, lifters, pushrods, and valve-train components are called hard parts. Consequently,  because they are the hard metal components inside of an engine.

There’s nothing more important to your vehicle’s performance than its engine.

So, The first rule of any auto repair job is never hurry! If things get rough, take a break. You may get a whole new perspective when you go back to work. Therefore, Keep distractions to a minimum. Also, Don’t panic if you hit a snag — sit quietly and think about it. If the parts fit together before, they’ll fit together again.

So, When an engine needs major repairs, you are faced with an important choice you can:

  • Replace the engine with a new
  • Remanufactured or used engine
  • Or you can repair or rebuild the original engine

As a result, Ignoring maintenance can lead to trouble: specific parts — or an entire system — can fail. So, Neglecting even simple routine maintenance can lead to poor fuel economy, unreliability, or costly breakdowns. It also may invalidate your warranty.

Here’s what happens as the engine goes through its cycle:

  • The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work.
  • Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful.
  • When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down.
  • Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to go out the tailpipe.

Now the engine is ready for the next cycle, so it intakes another charge of air and gas.
