Explained: V-twin, Stroke, And Valve In Bikes

Recognizing V-Twin 

Recognizing “V-Twin” 

Your motorcycle’s engine is a V-Twin. It also goes by the name “V2” engine. The number represents how many cylinders are in the engine; the V-Twin has two cylinders that have pistons. The interesting feature of this engine is its “V”-shaped arrangement of cylinders, which gives it its name. 

How are V-Twin engines set up on a motorcycle? 

There are two configurations for a V-Twin engine on a motorcycle: 

  • Transverse configuration 
  • Longitudinal configuration 

Transverse Engine Configuration 

You must visualise a 2D diagram of your bike in order to comprehend this configuration. Your engine would be situated between the two wheels on the same plane, its cylinders and crankshaft being visible and making a “V” shape. 

Longitudinal Engine Configuration 

In India, housing an engine on a plane perpendicular to your 2D bike’s plane is the second technique to place an engine on a 2-stroke motorcycle. This configuration is less common. Yet, because both cylinders have access to the air stream, it is thought to be superior for engine cooling. 

How Do V-Twin Engines Operate? 

Bike V-Twin engines function in the same way as any other car engine. The stages below outline the procedure: 

When the fuel intake is turned on, a carburettor pumps a mixture of fuel and air into the engine, where a spark ignites it. 

The gasoline and air mixture then ignites and explodes, pushing the pistons up and down until they experience these fuel-air explosions. This process is constant. 

The crankshaft attached to the V-Twin assembly is rotated by the action of the pistons, which transforms the heat energy of the fuel into rotational energy. 

Your bike’s back wheel receives this rotational energy from the transmission rails, which then propels it forward. 

Make sure you get two-wheelers insurance with adequate coverage to cover any unforeseen eventualities.

Recognising “Stroke”

A V-Twin engine’s combustion cycle has four stages: 

  • Take in fuel 
  • Compression of fuel 
  • Burning of fuel 
  • Expulsion of exhaust 

What do 2-Stroke and 4-Stroke engines in V-Twins do? 

V-twin engines are available in two variations: 

  • 2-stroke motors 
  • 4-stroke motors 

Functioning 4-Stroke Engine 

In contrast to a 2-stroke engine, a 4-stroke engine requires four piston strokes to accomplish one complete crankshaft rotation. 

Stroke 1 – The air-fuel combination enters the engine during the first stroke when the intake valve opens and the piston descends. 

Stroke 2 – in this stroke, all the valves are shut while the piston rises higher and compresses the air-fuel mixture. 

Stroke 3 – combustion occurs as the valves continue to be closed and the piston is in the compression position. 

Stroke 4: As the exhaust valve opens, all other valves remain closed. The piston advances while releasing gases. 

Recognising “Valves” 

The function of the valves of a V-twin engine is the same as that of any other valve in the real world. Their main job is to keep the energy and fuel in an engine where they belong. Depending on where a piston is in the combustion cycle, they serve as an inlet and an outlet.

A 2-stroke engine has “ports” instead of “valves,” as the name suggests. Three ports are present in a two-stroke engine: 

  • Induction port for air-fuel mixture 
  • Outlet to release exhaust gases 

A four-stroke engine, on the other hand, can have two or four valves. One valve is utilised for intake and the other for exhaust when there are two valves. Two valves are used for intake and two for exhaust when there are four. Do not forget to renew your insurance for two-wheelers on time.
