Earlier in the Engines section we saw how 4 stroke & 2 stroke engines work ! We might like to give a thought on which is better one OR which has more advantages. So in this article we are going to discuss about the differences, advantages & disadvantages of 4 stroke & 2 stroke engine. more “Differences, Advantages & Disadvantages of 4 stroke vs 2 stroke engine”
In my previous article, we learned how 4 stroke engines work ! This time we will learn about the second type of engine i.e 2 stroke engine. The 2 stroke engine is a type of Internal combustion engine where one power cycle is completed with two strokes of the piston during only one rotation of crankshaft. The first commercial two-stroke engine involving in-cylinder compression is attributed to Scottish engineer Dugald Clerk.
The 2 stroke engine performs all the same steps which are performed by 4 stroke engine – suction, compression, expansion & exhaust; but the 2 stroke engine performs these all steps in only 2 stroke unlike the 4 stroke engine which completes one power cycle in 4 strokes. more “How does a 2 stroke engine work ?”
These are the most basic engines used in cars & bikes i.e Four stroke cycle petrol engine OR 4 stroke engine(often called). It is very easy to understand until & unless you wanna do all the thermodynamic calculations & all that stuff ! more “How does a 4 stroke engine work ?”
We have travelled thousands of kilometers in trains, but we haven’t given a thought about how do trains turn during a curved path ? Both the wheels are connected through an axle & obviously are of same diameter. But,when a train takes turn, the outer wheel has to cover more distance than the inner one…! How is this possible ? How can the outer wheel cover more distance than the inner one even when both the wheels have same diameter ??? 🙁 more “How do trains turn without differential ?”
