These different outboard engines share some qualities. Both the two-stroke and the four-stroke need a mixture of fuel and air to be transported to the cylinder. Next the mixture must be put under pressure and then explode. This combustion for both engine types produces the smoke that you see coming from the tail pipe. It is essential that the innards of your engine are harmonious in both systems because this ensures that your engine running in this cycle.
A four-stroke outboard engine works basically like this:
First, the mixture is drawn down with the piston, which moves down the cylinder. This action concludes that first stroke.Then, the piston moves up again pressurizes the mixture and together with its piston rings it safeguards against troubles for the engine. This is the second stroke.
The third stroke consists of the explosion itself which twists the crankshaft. The piston, having been moved down by the explosion, moves the appendage joined to the crankshaft. The fourth stroke consists of the process settling down into its original state. This occurs when the crankshaft, in motion from the explosion, uses its appendage to place the piston back where it was before. This process also helps the burned gases to leave the engine.
You'll notice that this cycle produces a rocking, back-and-forth motion.
The two-stroke engine functions in a similar way, however there are some differences:
The significant difference here is the absence of conventional intake and exhaust valves. The ports in the four-stroke outboard engine function as valves, pushing gas in and out of the chamber. What the four-stroke can do in four individual strokes, the two-stroke outboard engine does in only two fluid motions. Another difference between the two outboard engines is that the four-stroke produces two turns o the crankshaft while the two-stroke produces only one. The valves in the four-stroke need some maintenance, occasionally. The two-stroke engines are without crankcase oil, are less efficient and produce more gases harmful to the environment.
