How a motorcycle engine works?

If you own a motorcycle, then you don’t need a therapist! Riding a motorcycle gives you ultimate pleasure, soul satisfaction, and happiness. But have you ever thought about how a motorcycle engine works? Modern bike engines are designed with a lot of advanced technologies. Sometimes, it can be a daunting question to think about how an engine works, and if you want to know the engineering behind a motorcycle’s engine, keep reading! 

How a motorcycle engine works?

The mechanism of the motorcycle engine is very simple to understand. They are designed with cylinder blocks, ahead with valve trains, and pistons. The pistons (inside cylinder) block moving up and down, driven by fuel-air mixture power, which is initiated by the ignition spark. The valve closes and opens through the combustion chamber to allow the flow of the fuel-air mixture. Pistons move in a perpendicular matter where the crankshaft transforms the energy produced due to pistons’ rotatory motion.

Then the rotational force obtained from the pistons gets transmitted into the motorcycle’s rear wheel. Now on the combustion chamber’s roof side, the spark created from the spark plug ignites the air and fuel mixture to start the combustion. This part is called the process of ignition.

The piston inside the motor is connected to the rod, which is called the connecting rod. The rod connects the crank, which is also known as a large axle. As soon as the combustion pushes the conrod and piston down, it turns the crank. The gasses burning inside the small spaces keep expanding rapidly. The combustion chambers floor is the top of the piston that slides down into the cylinder walls. And that is the main reason it’s called Cylinder! 

Crank’s momentum swings the piston back up and con rod to back up the cylinder immediately. This process helps the cylinder to push out all the exhausting gases out through the small valves. The valve’s opening and closing mechanism’s timing is controlled by a chain that runs through the crank back above the valves. When the combustion chamber’s insides are filled with air and petrol, the ignition spark starts up your motorcycle. 


Phew, The mechanism of how a motorcycle engine works is pretty long right. But thanks to the latest technology that gave us these amazing engines to run our motorcycles. Motorcycle engines are classified into three characteristics in general, depending on the capacity of chambers. If you are looking to buy a new one, check the engine horsepower, capacity, and a few other things to see if the engine power matches your speed requirements. The engine is the powerhouse of a motorcycle, so it’s always better to know more about it.
