Exhaust Manifold Function, How It Works and Its Components

For car owners, you need to understand how the exhaust manifold works and its supporting components. This way, you can pay more attention to this component when checking the condition of your car. To satisfy your curiosity, let's look at the function and operation of the exhaust manifold as follows.

Function of the Exhaust Manifold

There are several functions of the exhaust manifold that you need to know. Here are the complete functions.

1. As a special pathway for exhaust gas from the engine

The exhaust manifold functions as a special pathway for the disposal of gases from the combustion residues in the engine. These gases will be expelled through the muffler part of the exhaust.

2. Maintaining engine performance

The next function is to maintain engine performance to remain optimal and efficient. This happens because the exhaust manifold has a pipe diameter that is specially designed and calculated. This special calculation and design make the engine power optimal and fuel consumption economical.

3. As a sound damper for explosions originating from within the engine

The next function is that the exhaust manifold can dampen sounds like explosions from within the engine. This sound usually occurs when the engine is undergoing the combustion process. If the exhaust manifold is not designed, the sound can make your ears hurt because it is so loud.

In addition, this sound can also become noise pollution that disturbs the comfort of other road users. Therefore, car manufacturers create exhaust manifolds to address this issue.

How the Exhaust Manifold Works

The operation of the exhaust manifold is quite simple. When the gas is expelled from the combustion results of the engine, gas from each engine cylinder will be channeled to the exhaust manifold.

Here, the gas will be combined into one. Subsequently, the gas will be channeled to the muffler and catalytic converter. This way, the exhaust emissions can be expelled properly and environmentally friendly.

Supporting Components of the Exhaust Manifold

Here are some components found around the exhaust manifold that support its function.

1. Exhaust pipe

This component functions as a conduit for exhaust gases coming from the exhaust manifold. With this component, the gas disposal process can run smoothly because the exhaust pipe connects other exhaust components with the exhaust manifold.

2. Catalytic converter

This component functions as a filter for pollutants or other harmful substances produced during the combustion process before being expelled, making the exhaust emissions environmentally friendly.

3. Muffler and resonator

This component smooths the process of expelling gas from the combustion residues of the engine. In addition, this component also creates back pressure. As is known, the muffler is one of the exhaust components that can dampen the sound of explosions from exhaust gases.

Typically, exhaust gases have a temperature of around 600 to 800 degrees Celsius with a pressure of about 3 to 5 bar. This condition can cause loud noises in the exhaust. With the muffler, you can control the noise level.

4. Muffler tip or tailpipe

This component serves as an exhaust accessory to make it look more aesthetic. In this component, exhaust gases simply pass through before being expelled by the exhaust into the open air. Currently, there are tailpipes on the market that can be used to re-filter exhaust emissions.

Immediately visit a nearby Daihatsu dealer or a professional workshop if the exhaust manifold and other components have issues, to avoid harming the environment.
