What does the exhaust manifold do in an engine?
Exhaust System The exhaust manifold receives the air/fuel mixture from the multiple cylinders in your vehicle’s engine. It collects the fuel/air mixture from each cylinder, whether you have four, six, or eight cylinders.
What is engine exhaust system?
The exhaust system collects the exhaust gases from the cylinders, removes harmful substances, reduces the level of noise and discharges the purified exhaust gases at a suitable point of the vehicle away from its occupants. The exhaust system can consist of one or two channels depending on the engine.
Why do we need an exhaust system?
Your vehicle’s exhaust system is designed to take care of toxic emissions your car produces. It will 1) direct harmful hydrocarbons away from the driver and passengers, and 2) reduce the air polution your car releases into the environment, helping keep the air clean.
Where is the exhaust manifold in an engine?
It consists of an exhaust manifold mounted on the cylinder block or head, catalytic converter, and tailpipe/silencer. The exhaust manifold is a set of pipes that carry exhaust gases from the cylinder head to the silencer.
What are the different types of engine manifolds?
Types of Manifolds in Engine: 3. Intake Manifold 3.1. Constructional Details with Parts: 3.2. Working Principle 4. Exhaust Manifold 4.1. Constructional Details and Parts 4.2. Working Principle Manifolds are separate sets of pipes connected to the cylinder head which provide the air-fuel mixture and the exhaust gases, these are known as manifolds .
When do exhaust gases pass around the intake manifold?
When the engine is cold, all the exhaust gases pass around the intake manifold. When the engine is warmed up, a part of the exhaust gases goes around it, and when the engine is fully warmed up none of the exhaust gases passes around the intake manifold, but goes directly to the exhaust pipe as shown fig.

What is the working principle of a manifold?
Working Principle Manifolds are separate sets of pipes connected to the cylinder head which provide the air-fuel mixture and the exhaust gases, these are known as manifolds . It is usually made of cast iron so that it is capable to resist the high temperature of the exhaust gases.
What do you need to know about the exhaust manifold?
Important Facts You Need to Know About Exhaust Manifold. A huge part of this system is the exhaust manifold, which is used to vent gases away from the engine. This specific component extends from the cylinders to the exhaust pipe as it collects and moves exhaust away from the engine. When the pistons reach the exhaust stroke,…

Where does the exhaust come from in a diesel car?
An exhaust system from a diesel passenger car is illustrated in Figure 1. The exhaust system is typically connected to the exhaust manifold, which collects exhaust gases from the engine cylinders’ exhaust ports.
What should be considered when designing an exhaust system?
Well-designed exhaust systems collect exhaust gases from engine cylinders and discharge them as quickly and silently as possible. Primary system design considerations include: Minimizing resistance to gas flow (back pressure) and keeping it within the limits specified for the particular engine model and rating to provide maximum efficiency.
