Diesel Exhaust System: Things to Know Before Buying

Having a truck is helpful for many people in finishing their tasks. So, whether it is the 4th gen Cummins or a Duramax, many people have dreamed of buying their diesel trucks. But before purchasing one, it is vital to learn about the different diesel components to know what your truck can do. It can help solve problems in the truck much easier should a crisis happen while driving. And one of the most crucial parts that people should study is the exhaust system.

An exhaust system acts as the guide for exhaust gases to go out of the car. It is essential for vehicles as it prevents the gas from entering the vehicle’s interior, causing the passengers to inhale harmful toxins. A typical diesel exhaust system comprises an exhaust manifold, catalytic converter, oxygen sensor, muffler, and tailpipe.

The exhaust manifold of the system is the one nearest to the engine, sucking in all exhaust gases that will be delivered out of the truck. It is commonly made of cast iron or steel and is designed to improve exhaust flow. Oxygen sensors are used to measure the level of oxygen in the exhaust. This information can be beneficial for the fuel economy and performance of the truck.

A truck’s catalytic converter converts harmful gases in the exhaust into water vapors and carbon dioxide. This component is responsible for keeping the emissions safe for the environment. Moving on, a muffler is accountable for reducing the noise emitted by the engine while the truck is running. And a tailpipe is the alleyway of the exhaust gas to the outside world.

Because of its function of emitting unwanted gases out of the truck, exhaust systems are one of the most regulated parts of a truck. Air pollution continually worsens every year. That is why cutting down the emission levels is one of the critical regulations enforced in recent years. These regulations have resulted in innovations in modern exhaust systems to ensure that you abide by the rules.
