![]() ![]() There are a lot of moving parts and a lot of action going on with an engine. Along with the spark which creates an explosion of that mixture to move those pistons up and down. These systems all work together to provide the engine with the proper fuel and air mixture. These three systems are the fuel, the electrical, and the air systems. These can get pretty complex and confusing to someone that does not have a mechanical background, or that has never worked as a mechanic. The powerhead has three primary systems which operate the engine. We recommend reading this article we wrote here on What Is An Outboard Powerhead! We won’t go into the powerhead break down here, but for more information on the powerhead. The cylinders with their pistons are the mechanical parts that make up the powerhead. So, as one piston is sent down by the explosion, it pushes the piston next to it up! Thus as each one is pushed down, they force the others up, and the motion will continue up and down, up and down until the fuel stops coming in! The Different Systems of the Powerhead One piston will be all the way up, then the next piston in the cylinder next to it will be in the fully down position. The engine keeps this up and down motion by placing the pistons opposite from each other. Let’s say you have four cylinders with each cylinder having it’s own piston inside of it. ![]() The engine will have different cylinders, each cylinder having it’s own piston. When the fuel explodes, it pushes that piston down. The engine takes in an explosive substance, being fuel, and then sets the fuel on fire. Meaning they require an explosion for them to continue in motion. These pistons use “combustion” to move up and down. On a boat, with an outboard, it spins the propeller which moves the boat either forward or backward. In a car, it eventually turns the wheels on the car, moving it forward. This up and down motion spins a driveshaft that has something attached to it. We’ll just give a quick, simple description.Ī combustion engine has pistons that move up and down. Without going into a huge lecture on how 2-Strokes and 4-Strokes operate. We will need to understand a little bit about a combustion engine in order to get a grasp of what these components do. Visit our store or call us today at 1-80.The top section of an outboard engine is made up of many different components which makes the engine run.
