How Does A Chainsaw Engine Work?

There is nothing as strong as a tree. A thick tree trunk can take days to cut down when you don't have the right tool. Fortunately, there is a solution. A chainsaw. A chainsaw makes work easier.

A job that can take days, take only a few hours.... sometimes minutes, depending on the  thickness of the tree trunk. The question you're now asking yourself is: How does a chainsaw engine work.

The Main Parts Of A Chainsaw

If you understand the main parts of a chainsaw, you'll know it's a working mechanism. I promise you, it's not that hard to understand.

  • A saw blade built into a chain and wrapped around the metal guide bar
  • A small cylindrical gasoline

The chain on the saw looks like the one that you see on the bicycle running around the sprocket. The only difference here is that, it has 30 sharp teeth mounted at an interval.

How It works?

Step 1: Fuel

The first step is to fill the gas tank. The fuel should be enough to handle the project. In other words, your engine shouldn't be dead  when you are working. For that reason, make sure that the fuel is enough. A typical gas powered chainsaw consumes 0.5 liters of gas. Depending on the one you buy, look at the requirement

Step 2: The Combustion process

This process takes place in the cylinder, where the fuel-air mixture burns to generate energy that cause the piston to move back and forth. The engine runs using a two stroke action.

Step 3: Conversion motion

Now, the chainsaw engine comes into contact with a piston leading to  the conversion motion of the piston.  Another thing that takes place is the  power going to  the centrifugal clutch using the drive shaft. When this happens the chainsaw engine starts to move.

The engine continues to  move, but the chain won't spin  unless you want to cut the wood. For safety purposes, never let the chain spin when not in use. It not only wastes the energy and it's also dangerous for you.

Keep in mind that the more the engine moves, the more it consumes more fuel. Which  can be a little bit expensive to run. To save on the cost of fuel, you need to use the clutch more often.

You see, the centrifugal clutch is known for linking the  engine to pull the throttle. This prevents the chain from spinning and the chainsaw goes into the idle motion.

At this point, the clutch disengages from the movement of the chain in the idle state, protect the user from injuries and save fuel. The one thing that you should not forget is the guide. The guide bar gives the  chain more room to spin. Most guide bars come from the long steel plate material.

The working mechanism of the chainsaw engine  is not rocket science. But more importantly, is knowing how to keep yourself safe. Accidents do  happen with chainsaws, that's why it's important you understand their working mechanism
