We usually know two types of bike engines. Those two names are two-stroke engines and four-stroke engines. But many of us may not know what these two types of engines are. The two-stroke engines were originally used on many earlier model bikes. Of course, some bikes still use two-stroke engines. Today our topic is to know In this article, I will try to make things clear about the difference between these 2 stroke engines and 4 stroke engines. It seems like you are interested about how these two types of engines work. So let’s get started.

Two Stroke Engine Motorcycle
Now I am going to discuss here the two-stock engine. How does it work? There has one revolution of the crankshaft during one power stroke in the two-stock engine. In 2 stroke engines, the piston moves a total of 2 times. The 2 stroke engine is much lighter and costs much less to build and maintain. Another major problem with a two-stroke engine is that it is very expensive. Calculations show that it consumes about 1 gallon of oil per 1000 kilometers. And also it is not suitable for the environment.
Four Stroke Engine Motorcycle
After analyzing two stock engine, now I am going to discuss the four stock-engine. In fact, It has two revolutions of the crankshaft during one power stroke. The piston engine of four-stock is some less than a two-stock engine. It has a lesser ratio in terms of power to weight and it generated less smoke and shows more efficiency. The engines of four-stock are expensive due to lubrication and valves and are tough to manufacture.
Difference Between Two Stroke And Four Stroke Engine
At this time, I am going to present here all the different advantages and disadvantages of the two engines. The engine of two-stock is cheaper and simple for manufacturing, but the engine of four stocks is expensive to manufacture and it is basically heavier. In addition to the information, I have already arranged a list of two-stock engine and four stock-engine at a glance below. To get it, please follow the table below carefully.
Two stock | Four stock |
It has one revolution of the crankshaft during one power stroke | It has two revolutions of the crankshaft during one power stroke |
It generates high torque | It generates less torque |
Its uses port for fuel’s outlet and inlet | It uses valves for the outlet and inlet of a fuel |
Its engines result in lesser thermal efficiency | Its engines result in higher thermal efficiency |
It has a larger ratio in terms of power to weight | It has a lesser ratio in terms of power to weight |
It generates more smoke and shows less efficiency | It generates less smoke and shows more efficiency |
Requires more lubricating oil as some oil burns with the fuel | Requires less lubricating oil |
Due to poor lubrication, more wear and tear occurs | Less wear and tear occurs |
Engines are cheaper and are simple for manufacturing | Engines are expensive due to lubrication and valves and are tough to manufacture |
Engines are basically lighter and are noisy | Engines are basically heavier because its flywheel is heavy and are less noisy |
Which Engine Is Better Overall?
Now it is time to decide which engine is better. It must be said that the 2 stroke engine is very good in terms of performance. And its power is much higher. But, if we think from the overall point of view, then the 4 stroke engine is also perfect. If you need power and you have a lot of money in your pocket then 2 stroke engine is definitely good for you. And usually, a 4 stroke engine seems to be good for any rider. And just remember 4 stock engine is good for the environment.
