Although simple in concept, the complexity of the internal combustion engine is mind-boggling. Most of the time we take it for granted when we turn the ignition key, shift into gear and step on the gas, but a marvel of mechanics, managing thousands of little explosions each minute, keeps us traveling smoothly down the highways and byways and streets where we live.

This video gives us an animated look at a virtual engine, from bare block to ignition. The inline-four engine is made by Deutz, an independent German machine manufacturer. See every component: casted this, braided that, spinning this, machined that. The animated video shows the engine assembling itself, then gives you an inside look at the combustion compartment, injecting fuel, igniting it and expelling the exhaust fumes.

As you marvel at the complexity of it all, remember that this is a relatively simple four-cylinder engine. Imagine throwing in a few more cylinders, a turbocharger or two, variable valve timing... you get the idea.

      Now, for comparison's sake, an electric motor:


      One moving part. Two bearing interfaces. No oil or coolant. No intake or exhaust.

      Consider how much easier to manufacture and service that is. Not that you would ever have to service it, since almost nothing can go wrong.

      Great video, though. The internal combustion engine is an impressive feat of engineering, complexity notwithstanding.

      Same thing for transmissions please. ?
      • 8 Years Ago
      Sure looks like a Honda B-series engine, but then again maybe most inline-fours look like that anyways.

      please send me some videos of ic engines,new designs,new modles of engines.

      Concerning rotary engines, have a look at mine.

      Excellant. thanks for nice service.

      In order of introduction:

      Engine block (big alu / magnesium)
      Piston bearings

      Engine head


      Head gasket

      Then, engine head goes on the engine block

      Oil pump
      Timing belt (in this case, timing chain)
      Timing belt cover

      Rocker cover with oil cap
      Rocker cover gasket

      Oil sump
      Oil filter



      Water / cooling in and out and piping

      Inlet manifold with throttlebody at the top right (silvery thing)


      Injectors (green)

      Electric wiring for injection and ignition system

      Spark plugs + distributor cap

      Engine turns over - Water pump goes on

      Auxhillary water pump goes on


      Exhaust manifold (gold coloured)

      Then demonstrates how an engine works when its running. Rather self-explanatory.

      Excellent. I like that. How do I save that to the desktop?
      • 8 Years Ago
      Superb video!

      Here's another one showing a simpler engine design:
