MS 171 そしてMS 251 両方とも best chainsaws STIHL製. The main difference between them is their engine displacement; MS 171 has a 31.8cc engine, 一方、MS 251 has a 45.4cc engine. それに加えて, MS 251 is designed to be tougher and more durable, as it’s built for professional use, 一方、MS 171 is designed for homeowner use. Engine Displacement The engine displacement of a chainsaw refers to the amount of fuel and air the saw can draw in during each cylinder cycle. 一般に, for chainsaws this metric is measured in cubic centimeters (cc), which indicates how many cubic centimeters of air and fuel the engine can take in at once.

Power output refers to a variety of different measurements used to describe how much of an engine’s power is being produced. Power output can be measured in horsepower (HP), which is the amount of power produced per minute and is the unit most people are familiar with. でも, horsepower is somewhat misleading, as it doesn’t always represent the best way to compare different engines. 例えば, an engine may have a higher horsepower rating, but if it produces more heat or doesn’t use its power efficiently, it will not be as effective as one with a lower horsepower rating that does those things well.
So for the purpose of this article, I’m going to talk about two measurements that are both more direct and interesting ways of comparing different engines: A two-stroke engine, such as the one on a STIHL MS 251 チェーンソー , has two strokes to complete each cycle (move forward, move backwards).
