This is how the exhaust system of an engine functions. The gases are then directed to the muffler, and released through the tailpipe. Once the harmful gases have been taken care of, the filtered exhaust gases travel through the resonator a resonator performs the job of reducing the noise produced by the engine. The gases are collected in a common pipe connected to the manifold or header and are further directed to the catalytic converter, which is designed to reduce or neutralize harmful, polluting gases. The resulting gases are channelized into the vehicle’s exhaust through either the manifold or the header. In the last stroke, the engine rids residual gases generated due to the combustion of fuel via an outlet valve designed to channel them to the vehicle’s exhaust system.Įach cylinder head is connected to a separate pipe, protruding from the exhaust manifold or header. Each stroke performs a function, the first one is for intake, the next is for compression, then combustion, and the last one is for exhaust. A four-stroke engine uses four strokes to complete one cycle of combustion of fuel. Let’s take the example of a four-cylinder, four-stroke gasoline engine to make things easier. Check it out! Working of an Engine’s Exhaust System
To understand manifolds and headers, it’s essential to understand briefly, the functioning of an engine’s exhaust system.įurther explained is a manifold/header’s role in the exhaust process, and a detailed comparison between the two. Most exhaust systems consist of a manifold or header, a catalytic converter, a silencing central section, a muffler, and a tailpipe.Įach of these parts is either meant to reduce the discharge of harmful pollutants, or to reduce the noise generated by the engine. One supplies fuel to it, and the other channels the smoke from the burnt fuel to the vehicle’s exhaust system. Copper GasketsĬopper gaskets are used in manifolds as well as headers to make them airtight and avoid exhaust noise and gas leakage.Īny and every car engine has majorly two types of valves. exhaust header comparison to understand the differences between these major components of a vehicle’s exhaust system.
This WheelZine post undertakes an exhaust manifold vs. It is situated between the two cylinder banks on V-8 engines.Although exhaust manifolds and headers seem to perform similar functions, they have substantial differences between them. The intake manifold has mounted a side of the cylinder block in L-head engines and on the side of the cylinder head in I-head engines. The carburetor is mounted on the intake manifold. Except where the superchargers or governors are used, the intake manifold is constructed so that, when the carburetor is attached to it, the mixture can reach each cylinder.
The intake manifold is a cast iron or aluminum tube for carrying the air-fuel mixture from the carburetor to the engine intake port.

It is usually made of cast iron so that it is capable to resist the high temperature of the exhaust gases.
