There are a couple, less parts for one therefore lighter. Also, 2 stroke engines fire every time the piston comes to the top. Which means every stroke is a power stroke. 4 stroke engines fire every other time.

Advantages of two stroke engine over a four stroke engine?
Explain the advantages of four-stroke engine over two-stroke engine
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
What kind of engines does NASCAR use?
NASCAR uses stock engines, with many of the racers using the engines created by Roush-Fenway. These are four stroke engines that reach horsepower of over 800.
What is two advantages of a four stroke cycle engine over a two stroke cycle engine?
Pollution - 4 stroke has far less unburnt hydrocarbon in the exhaust.
What is advantages four stroke engine?
When comparing to a two-stroke engine, the four-stroke engine has the following advantages.Fewer emissions. Since the crankshaft has its own oil reservoir there is no need to add oil to the fuel, meaning there is no oil burned in the fuel.Better fuel consumption. The four-stroke engine complete a full cycle in four-stroke. This gives it greater control over which ports open at which times. On a two stroke engine, fuel and air is being forced into the cylinder while exhaust is being forced out, this causes some fuel and air to flow directly through the cylinder and out the exhaust. Four-stroke engines are also directly fuel injected which allows greater control over fuel delivery.Longevity. The four-stroke engine has a lower power to weight ratio than the four-stroke engine. In this respect, the engine components aren't pushed as hard as a two-stroke. This allows them to last longer.
How to Choose an Outboard Motor?
Instead of buying a new boat, the best alternative may be simply purchasing a new motor. For those that have fishing boats and other working craft, he or she probably has an outboard motor, which are popular on these particular vessels. Outboard motors can be found in a number of places although it is best to purchase one from an authorized dealer or someone that is trustworthy. The reason for this is that simply outboard motors require special knowledge of engine parts to repair and refurbish. If the proper care and time is not taken for the repair, the motor could fail at the most inopportune time.Four Stroke EnginesThe most popular outboard engines of the present are the quiet and reliable four-stroke engines. These engines have recently made their debut over the last ten years because of their ease of use. Four-stroke engines do not use oil as two-stroke engines do, and they also use less gas than two-stroke engines. Also, the four-stroke engine is much quieter than the noisy two-stroke engine, which makes it far less intrusive for those long trips to the Gulf Stream. The only down-side to four-stroke engines are that they are more expensive than two-stroke engines. Four-stroke engines are also considered safer to purchase from classified advertisements or other places. Four-stroke engines do not require specialized repair personnel for general maintenance and small repairs. A 150 horsepower engine can be found for prices starting at $5000.Two Stroke EnginesTwo-stroke engines are the most traditionally used outboard motor on the market. They incorporate the use of oil in their gas tanks and are said to be able to attain more overall torque than four-stroke engines. Two stroke engines are great engines and can be found re-built for relatively cheap. For instance, $500 will get one a two-stroke outboard motor up to fifty horsepower. The best place to look for two-stroke outdoor motors are at authorized used boat dealers or licensed small engine repair shops. Two-stroke engines are different from other engines and takes one with specialized knowledge to make even the most general repairs.
What are the disadvantages and advantages of a jet engine over radial engines or piston engines used for aircraft's?
The advantages, you move over a lot more land in a lot less time. The disadvantages, Jet engines use a lot more fuel, and are a lot louder.
What makes a two stroke engine produce twice as much power as a four stroke?
A 2-stroke engine makes power every2 cycles were a 4-stroke makes power every 4.Hence 2x power. This is absolutely INCORRECT! A two stroke engine develops it's PEAK horse power twice as fast as a four stroke for the reason given but that is it. For a given displacement a four stroke engine will ALWAYS make more torque and horsepower than a two stroke engine of equal displacement. This is due to the fact that a four stroke engine cleans the cylinder of contaminated (exhaust) air, compresses the air/fuel to a more efficient level, and draws a cleaner air/fuel mixture into the cylinder as there is no slow burning, air/fuel mixture contaminating oil mixed in the combustion charge. I have over forty years experience working on engines, and can tell you, the ONLY reason two stroke engines have lasted this long, is due to the fact that they weigh less than an equivalent horsepower four stroke engine. If they DID develop more horsepower, the four stroke would not have become the standard internal combustion engine used in transportation, generators, air compressors and the like.

What does stroke mean for quad bikes?
Stroke refers to how the pistons move in the cylinder(s).The basic meaning is the length of the piston travel. Short stroke engines can turn over faster, but long stroke engines tend to have more pulling power.Stroke can also be used as 2-stroke and 4-stroke, which refers to the different work phases of the engine. 2-strokes give more power for their size, but they pollute more and often use more fuel. 4-stroke can be cleaner, but bigger, heavier, and have more parts.
What is the most common cam used in todays car engines?
Most common camshaft used in today's car engines is DOHC (Dual Over Head Camshaft). Most of the manufacturers in the world are using this cam shaft in their cars, as it is most practical and has a four stroke cycle and gives more breathing space to the engine.
How long will a power stroke 7.3 diesel engine last?
The Ford power stroke 7.3L diesel is one of the most reliable engines in production. Many will perform well over 500,000 miles.
