Water-Cooled Engines

There are so many different types of engines out there that it’s a challenge to remember how each one operates. So next time you’re filling your water-cooled engine up with Evinrude xd50 oil you may want to consider that because engines create so much heat during the combustion process they need to be cooled often. Water is much better at conducting heat than air. Water-cooled engines can often be found in motorized bikes.

Here’s how a water-cooled engine works: A water-tight jacket fits around the head and cylinder of the engine to carry heat away from the heart of the engine. The water is then circulated through the tubes in a loop from the cylinder to a radiator, where the water is cooled by air. The water then returns to the engine to pick up some more heat.
