[T1394]Two And Four Stroke Engines
by Maricon Williams, Mar
Same in the case of motorcycle, you have to know the different motorcycle parts, their function and distinction so as to understand their chemistry and importance. Let us take internal combustion engine as an example. The best way to start is to have a substantial comparison. You have to know the types of engines in order to decide what’s best for you. You have to consider its pros and cons...

We have two types of motorcycle stroke engines – the two stroke and the four stroke engines. The first one involves two processes - compression and combustion. On the other hand, the cycle in four stroke engines involves intake, compression, combustion and exhaust.

If we are to give their advantages here are some. In two stroke engines, the engine fires, spark plugs ignite once every revolution of the crankshaft. It involves simple process with fewer parts. Its power is two times better compared to four stroke engines. In connection with the four stroke engines, they have proficient use of gas. They also give off lesser smoke than two stroke engines. Above all, they last longer.

How about the disadvantages? With the two stroke engines, you have to mix its oil with gas. This can be costly. They can also give off greater pollutants. The use of gas is also mot proficient. Lastly, they last less. With the four stroke engines, their drawbacks include their complicated nature since there are more parts to attend to, they only fire once every two revolutions, and they have half as powerful as the two stroke engines.

After knowing the positive and the negative sides of these two types of engine, you can now determine which of the two you like the most. It’s just a matter of what you like and what works for you.


Many years ago when I got hooked by motorcycles I started to hear about the two and four stroke engines... It seemed there were (and there still are) strong opinions in pro and con of each of the engine types.

As Internet wasn't available, and as I was worried about other aspects or motorcycle riding in that time, I left that question unanswered for a long time.

If this is your case or if your are interested about these two kind of internal combustion engines, in the next few lines I hope to give you a
few fast answers and some resources to get more in deep information.

Just keep reading...

Here are some facts about two and four stroke engines:

TWO STROKE ENGINES

Cycle - Two Strokes:

1.- Compression (intake+compression)
2.- Combustion (combustion+exhaust)

Take a look at the cycle in:
http://science.howstuffworks.com/two-stroke2.htm

Advantages of two stroke engines:

• The engine fires - spark plug ignites - once every revolution of the crankshaft.
• They produce twice the power than four stroke engines.
• They are much simpler than four stroke engines. Fewer parts to worry about.

Disadvantages:

• You have to mix two stroke engine oil with gas, and depending on your consumption, this might be expensive.
• They last less. Lubrication is not as efficient as in a four stroke engine with heavy oil.
• Do not use gas efficiently.
• Pollute more.

FOUR STROKE ENGINES

Cycle - Four Strokes:

1.- Intake
2.- Compression
3.- Combustion
4.- Exhaust

Take a look at the cycle in:
http://science.howstuffworks.com/engine4.htm

Advantages of four stroke engines:

• Last longer than two stroke engines
• More efficient use of gas
• Pollute less than two stroke engines

Disadvantages:

• More complicated. Many more parts to worry about.
• Half as powerful as two stroke engines (for equivalent engines)
• Fires once every two revolutions.

If you want to learn more about two stroke and four stroke engines, take a look at the pages I mention above. You will find extensive information and diagrams that will solve all of your doubts.

Well I hope this gave you some basic information and helped you answer some FAQ about two and four stroke engines! :-)

Enjoy the ride!
