A few fast responses and facts about Two and Four Stroke Engines.

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:

• 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!

Every once in a while, someone starts a campaign to lower gasoline prices by urging everyone not to purchase any gas on a certain date. The chosen date is far enough in the future to allow for a massive e-mail and newscast campaign to spread the news far and wide throughout the land and get everyone geared up for the big day. The idea is that the resulting surplus of unsold gas would force distributors to lower the prices in order to be able to unload the stuff. There are two problems with that idea: 1) almost no one participates and 2) those who do participate buy their gas either the day before or the day after the target date, so the net result is the same amount of gas is sold and the price stays too high.

I have noticed that most drivers completely ignore the speed limit on the freeway. Where I live, the freeway speed limit in the city is 65 mph. It is quite possible to drive that fast in the right hand (“slow”) lane and have people come up on your bumper and give you an annoyed look as they go around you because they think you are driving too slowly! 80 mph in the left hand (“fast” or “passing”) lane is normal, as are people in hurry braiding in and out of lanes because they think their time is more important than yours and you are in their way. You might not want to hear this, but such driving wastes gas! The same gas you complain and moan about every time you fill out at the pump gets wasted out on the freeway by such drivers. Maybe even YOU??? (Nah………..)

According to the website Howstuffworks, the best mileage can be achieved by driving between 40-60 mph. Now I’m here to tell you that driving 40 mph on the freeway will get you one of three things: 1) a ticket for impeding the flow of traffic 2) into - or becoming the cause of - and accident 3) killed. However, driving at 60 mph won’t cause any more dirty looks than driving at 65, as long as you stay in the right hand lane. You won’t cause any accidents, and you won’t get a ticket for impeding traffic. Again, according to Howstuffworks, gas mileage decreases rapidly at speeds above 60 mph. So you are wasting gas and wasting money by driving faster than 60 mph.

Now I can hear you already: “But, I’m late!” Plan ahead, and leave a couple of minutes earlier. Think about it for a minute. If you drive 65 mph for one whole hour, you will only be 5 miles farther down the road that if you drove 60 mph for that same hour. Those of you who spend a whole hour commuting are usually not driving 65 miles. You are driving more like 10 miles, crawling along at jogging speeds. This won’t work for that sort of commute. However, if your drive is such that you have the option of driving faster than 60 mph, DON’T! Set your cruise control at 60 mph, slow down and save.

The beauty of this system is that you benefit from it even if no one else participates! There is a very real possibility that you could fill up your tank one less time per month. That would save you $20-$50 per month, which is $240-$600 per year. Spend it on Christmas presents. Splurge a little on your vacation. There are lots of ways you could enjoy the extra money. And if other people participate, because more and more people would be buying one less tank of gas per month, the supply really would go up because the demand really would be down, and that would mean lower prices which would benefit everybody (except maybe OPEC, and they don‘t need the money.) Try it!

There is nothing more fun than spending a day racing and performing tricks on your ATV. However, it is important to always check your ATV tire before you start. Many ATV accidents are caused by ATV mud tires that are either over or under inflated. If your tire is not close to the recommended pressure amount, you could lose control of your ATV. Also, be aware that the tire pressure can vary greatly just from temperature changes throughout the day. When buying ATV tires, make sure that the tires you are buying are compatible with either the ATV you have or the ATV you are planning to buy. As a general rule, sport-utility ATV’s should have mid sized tires, while sport ATV’s, which are usually used for racing and stunts, should have larger sized tires. If you do not know what tire size is correct for your bike, consult your ATV manual.

While ATV mud tire prices are generally a little high, you will get what you paid for. The higher quality ATV tires will last much longer, provide more traction, and remain effective long after the discount tires have been worn down. Also, higher quality ATV mud tires have been proven to be generally safer than the cheaper models. If you are not able to afford a high quality tire, make sure to properly maintain your ATV tire, and check the tire pressure often.

Dunlop motorcycle tires have been long known for their high quality and reliability. Worldwide, motorcyclists of all skill levels depend on Dunlop motorcycle tires. In fact, Dunlop tires are used by more motorcyclists than any other brand. This is largely because of Dunlop tire’s devotion to excellence. In order to learn how successful the company is today, it is necessary to look at the company’s history. In 1888, John Boyd Dunlop invented the first practical pneumatic tire. In doing so, he created a whole new industry. Using innovative technology, Dunlop introduced the first use of Kevlar belts in motorcycle tires and produced the first original-equipment radial street tire. Dunlop tire also continues to lead the industry with new ideas, like the 20-inch front tire for off-road use. Dunlop leads the motorcycle tire industry in its continuing research to improve the motorcycle tire. Also, Dunlop is still the only company to make motorcycle tires in the United States.

It is important to take care of your Dunlop motorcycle tire. Be sure to properly maintain it by storing it properly and maintain suspension settings in exact compliance with the vehicle owner's manual. If your motorcycle tires are improperly maintained, it could lead to flats, low tire pressure, or other potentially dangerous situations. If you don’t have any experience maintaining your motorcycle tire, be sure to take your motorcycles in to the motorcycle dealer for regular maintenance checks.
