Every internal combustion engine needs oil for lubrication, but two-stroke engines take their oil regularly along with gasoline.

Since two-stroke engines have fewer moving parts, they are easier to manufacture, and logic would dictate they would be easier to maintain. That couldn't be further from the truth due to friction.

How hard could it to be to build a two-stroke internal combustion engine (ICE) from scratch? This is a challenge that [Camden Bowen] gladly set for himself, while foregoing such obvious wastes of t… ...

Since two-stroke engines are more polluting, they were banned for most street motorcycles. Still, they are used on lighter applications such as lawnmowers, generators, or go-karts.

As for lubrication, the fuel and air coming into a 2 stroke will contact all internal components of the engine. Because of this, you need to mix oil (the lubricant) with fuel before putting it in ...

Two strokes have fewer working parts that can go wrong, and they don’t require oil changes. What is the disadvantage of a 2-stroke engine over a 4-stroke engine? One of the biggest disadvantages of a ...

Two-stroke engines used to be ubiquitous in dirt bike racing, thanks to their lightweight construction and horsepower. Packed in a dirt bike frame, they make a motorcycle playful in the corners ...
