How your bike's exhaust improves its performance

November 24, 2013 13:20 IST

Ever wondered what keeps away the gases that are formed when fuel is burnt within the engine? Well, it's an important part of the bike.

The exhaust system works hard to take care of the bike and prevent any harmful impact of the gases developed during combustion on the bike's performance.

The role played by the exhaust system not only entail protection but also works for the improvement of performance. Read on to know how a bike's exhaust system improves its performance.

Primary functions of the exhaust system in bike's performance

Removal of toxic waste

As explained above when engine burns fuel to power the bike a lot of toxic waste like poisonous gases are generated. It is important to drive out these gases to ensure proper and smooth working of the bike.

The exhaust system serves as a vent through which these waste gases are channeled out of the bike's system. Choking and subsequent breakdown of the engine is prevented as the gases are channeled out of the engine by the exhaust system.

Noise reduction

Gases generated during the fuel combustion would have ordinarily created tremendous amount of noise if, they were let out to escape directly. Instead of directly releasing the gases out of the engine, the exhaust system channel's these gases out of the bike through muffler, plates and other equipments which aid in substantial reduction of noise.

Mufflers absorb the sound energy from the passing gases while they are removed from the bike.

Reduction is green house emissions

Environmentally unfriendly gases like nitrogen oxides and carbon monoxide are released during the combustion process. Catalytic converter within the exhaust system of the bike prevents the escape of these harmful gases into the environment. It transforms carbon monoxide into water vapour and less harmful carbon dioxide. This aids in reduction of emission of green house gases.

Other functions of the exhaust system in bike's performance

Improving performance of engine

The diameter of the exhaust pipe controls the gas flow and velocity generated. Larger pipe diameter leads to increase in the flow of gases which causes reduction in the velocity and torque of the bike. While smaller diameter of pipe reduces fuel efficiency.

Reducing back pressure on engine

Back pressure on the engine which is created because of obstructions in the exhaust pipe can negatively impact the engine performance. Back pressure can substantially lower the engine's power and fuel efficiency. Exhaust system should, therefore, prevent incidence of back pressure on the engine.

Improving fuel economy

Exhaust system lead to an improvement of engine power. Increased engine power means that the engine requires lesser fuel to move the bike forward. Exhaust system helps in improving fuel economy of the bike.

Exhaust system of the bike plays a critical role in the proper functioning and performance of the bike. Take proper care of the exhaust system and reap rewards as the exhaust system improves your engine performance and fuel economy!
