Two and Four Stroke Engines - Fast and Simple Answers

Many years ago when I got hooked by motorcycles, I started to hear a lot about 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 back then, I left that question unanswered for a long time.

If this is your case or if your are interested in 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 depth 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:

o The engine fires - spark plug ignites - once every revolution of the crankshaft.

o They produce twice the power than four stroke engines.

o They are much simpler than four stroke engines. Fewer parts to worry about.

Disadvantages:

o You have to mix two stroke engine oil with gas, and depending on your consumption, this might be expensive.

o They last less. Lubrication is not as efficient as in a four stroke engine with heavy oil.

o Do not use gas efficiently.

o 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:

o Last longer than two stroke engines

o More efficient use of gas

o Pollute less than two stroke engines

Disadvantages:

o More complicated. Many more parts to worry about.

o Half as powerful as two stroke engines (for equivalent engines)

o 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! :-)

Honda Super Cub and 50cc Honda Cub - The Volkswagen Beetle of Motorcycles!

A very clever design: the Honda Super Cub was the combination of a moped and a scooter. It attracted many people due to its friendly and non intimidating look. People who before had felt threatened by bigger motorcycles, approached and adopted this model very quickly.

It was a versatile motorcycle and had enough power to carry two passengers or a passenger with luggage. Its large diameter tires and wide seats made the ride almost as comfortable as the touring bikes from that time.

>> Honda 50cc Cub and Super Cub FACTS

- In 1952 Honda built 7000 units of this bike which represented the 70% of the entire production of Japanese motorcycles for that year.

- Thanks to this model Honda Motorcycles were absolute market leaders during 1953 and 1954.

It's worth mentioning that those were very competitive days. There were many manufacturers competing for a very fast growing and demanding market.

- The Honda Super Cub was the equivalent of the Ford T or the Volkswagen Beetle for automobiles. As of 1992 Honda Motorcycles had built 20 million of these machines.

- The Honda 50cc Super Cub was exported to 120 countries.

As the Volkswagen Beetle, the Honda Super Cub didn't change much through time. Just take a look at the technical data below:

1959 Honda Super Cub Specifications

-> Four stroke horizontal engine. -> 49 cc of displacement -> Three speed semi-automatic gearbox. -> U-shaped frame in stamped steel. -> Weight: 155 lbs. (70 kg.) -> Speed: 35 mph (57 kph)

1992 Honda Super Cub Specifications

-> Four stroke horizontal engine. -> 49 cc of displacement -> Three speed semi-automatic gearbox. -> U-shaped frame in stamped steel. -> *Weight: 122 lbs. (55 kg.) -> *Speed: 50 mph (80 kph)
