Do You Know What The Difference Is Between A 2-Stroke Engine And A 4-Stroke Engine?

Operating Safety

Engines have evolved enormously in recent years drastically reducing the level of noise produced. As well as the level of pollution due to exhaust gases improving fuel consumption and operating safety.

Here in your Moto Magazine. We explain the main differences between one and the other as well as its advantages and weak points.

Broadly speaking we can say that the 2-stroke engine works by producing an explosion for each revolution that the piston makes to the crankshaft. While the 4-stroke propellant, an explosion occurs every two turns.

At present 4-stroke engines are much more popular than 2-stroke ones, since. As we will see below, they are more efficient and respectful of the environment. Today we only find 2-stroke engines in those mopeds with reduced power or certain Enduro or Motocross models.

 2 stroke engines

They are low-power engines, their composition and operation are much simpler than in the case of 4-stroke engines. This engine requires that the fuel pass through all parts of the cycle without mixing with the oil so that it can lubricate.

During its passage the oil burns which influences the strong odor that is given off and the greater contamination. In addition in these engines part of the fuel is wasted. Since it does not explode, causing greater wear although on the other hand they are cheaper to manufacture and their maintenance is less than in the other case at hand.

The only steps they go through in a 2-stroke cycle are compression and combustion intake as well as exhaust. With this simplification in operation it causes the engine to turn much faster than in a 4-stroke and that its nerve provides much more performance in acceleration.

In the event that you ride a 2-stroke motorcycle remember that since oil mixes with gasoline. It is essential to regularly check the level of the lubricant. That is why 2-stroke engines produce more smoke than 4-strokes. Because the spark plug is burning gasoline mixed with oil and not pure gasoline.

The two-stroke engine times it is much cheaper because it does not use valves in its mechanisms. Making it also much smaller than its older brother. Finally by working more times than the four-stroke engine a two-stroke machine can show greater wear.

4-stroke engine

Now in the larger engine, the 4-stroke, unlike the previous one, gasoline and oil do not come into contact. They tend to be larger and heavier, but consume less fuel, pollute less and are quieter.

The mechanism of these engines may seem simple at first glance, although since the lubrication zone is separated from the combustion zone inside to introduce gasoline and oil separately. A few more steps are necessary for them to work perfectly.

It uses an oil that lubricates the interior of the engine, and another that lubricates the cylinder liner (for this type of engine the oil you buy is separate) the motorcycle system.

Itself is responsible for mixing it with the gasoline so that the piston and the rings do not wear as they go up and down the cylinder.

This type of engine is made up of a greater number of parts, such as a cylinder, a connecting rod a spark plug two valves a crankshaft and other complex components that favor its correct operation.

Performance and efficiency

Taking into account that 4-stroke engines offer lower performance and efficiency, the strengths are diverse. Among the main advantages. We must highlight the considerable savings in oil which does not burn in the explosion so in this case it will not be necessary to control its level so regularly.

Verschil Tussen 2-Takt en 4-Takt Motoren this also causes a direct consequence in the reduction of odor and polluting emissions to the environment and its mechanics includes a more complex structure to ensure that the different tasks do not overlap and achieve a more efficient use of fuel, without wasting it as much as possible. minimum

This type of engine consumes less gasoline, which in turn results in less gas production and less pollution. Since its intervals between combustion explosions are wider less vibration and less wear are generated making it a more reliable engine.

A disadvantage of this motor is that it is more complex in its construction, weight and therefore the price increases, and therefore repairs tend to be more expensive.
