2-Stroke V/S 4-Stroke - Which Is Better and Why?

There are many different methods and technologies applied to vehicular engines. The stroke in an engine is a very important concept that you must know to fully understand how your bike performs. There are two types of strokes found in two-wheelers, namely 2-stroke and 4-stroke. You need to be aware of this when you buy your bike, as it will help you to get a suitable bike insurance plan as well.

What Is a Stroke In A Bike?

To function properly, the engine requires fuel, which is a mixture of petrol and air. It burns the fuel and releases the fumes. This process propels power and makes the bike move forward. The process happens in two or four strokes (movements) of the piston within the combustion cylinder. In a 2-stroke engine, the entire combustion process happens in two complete movements of the piston. In a 4-stroke engine, there are four distinct movements.

Difference Between 2-Stroke And 4-Stroke Engine

Listed below are the key differences between a 2-stroke engine and a 4-stroke engine. Take a look for a better understanding:

1. Movements

The entire combustion process is completed in two full movements of the piston in a two-stroke bike. In the case of a four-stroke bike, four different movements happen for four different actions which are intake, compression, combustion, and exhaust.

2. Fuel

The oil in a four-stroke bike is very pure and not mixed with fuels of any other kind. This makes it more fuel-efficient. However, in a two-stroke bike, the oil is mixed with certain lubricating fuels to make the process smoother.

3. Valves and pipes

There are separate valves for the intake and exhaust functions in the 4-stroke bikes. However, in the 2-stroke bikes, you will find chambers that open and close as the piston moves up and down. Furthermore, the exhaust pipes in the 2-stroke vehicles are found to be larger than those of the 4-stroke engines.

There is no clear winner between the 2 stroke vs 4 stroke bikes. You get good models in both categories. Go over the bike features and choose the one that meets your requirements and budget.

Conclusion

As mentioned above, you will need to get a suitable bike insurance plan when you buy your bike, whether it is a 2-stroke or 4-stroke. Depending on a basic third party bike insurance policy may not be enough, so explore the comprehensive plans to see which one is best suited for you.
