A two-stroke engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust functions occurring at the same time. Another form of rotary inlet valve used on two-stroke engines employs two cylindrical members with suitable cutouts arranged to rotate one within the other – the inlet pipe having passage to the crankcase only when the two cutouts coincide.
The clue is in the name! A chainsaw has two main parts: a saw blade built into a chain, wrapped around a long metal guide bar, and a small, one-cylinder gasoline engine. Chainsaw helmets with visors offer some protection; so too do chainsaw uniforms. Wayne’s Chainsaw Museum: A short video tour of Wayne Sutton’s chainsaw museum in the United States, will hundreds of saws dating from about the 1930s.
These main parts work together in the above order to power and operate a chainsaw. Chainsaw maintenance varies depending on the type of chainsaw and the frequency of usage. The most popular ones include the best chainsaw for cutting firewood, what to look for in the best 18 inch chainsaw for bigger jobs, and the top rated chainsaws available.
The chain is the part of the chainsaw whose components do the actual cutting. The chain’s cutting part is called the cutter teeth or cutting link. Let us look at the cutting links that make the chain such a special component of the chainsaw.
how do chainsaw engines work Related Question:
How are chainsaws powered?
Chainsaw engines are traditionally either a two-stroke gasoline (petrol) internal combustion engine (usually with a cylinder volume of 30 to 120 cm3) or an electric motor driven by a battery or electric power cord. In a petrol chainsaw, fuel is generally supplied to the engine by a carburetor at the intake.
Does a chainsaw engine have valves?
These engines consist of relatively low weights and easy construction thanks to the absence of valves that reduce the weight of these engines. Almost anything, like a chainsaw, is made up of two-stroke engines.
Are STIHL chainsaws two-stroke?

Are chainsaws two-stroke engines?
These days, you’ll find two-stroke engines in all kinds of gas equipment, such as chainsaws, string trimmers, hedge trimmers and leaf blowers, largely because two-stroke engines have fewer moving parts, generate less heat and are in many ways more efficient for their size.
What does a decompression button on a chainsaw?
A decompression valve releases some of the compression from the combustion chamber during the starting procedure, making the engine easier to turn over when pulling the recoil rope.
