Jan 20, 2022 · 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 in fig.

Engine manifold is a complex tubular structure that is used for the exchange of input and exhaust fluids from an IC engine. Engine manifolds generally have one opening on one side and more than one opening on the other side, this means that the single tube branches into several branched tubes. The input fluid gets disturbed evenly among the branche...
As discussed earlier the engine manifold transports fluid in and out of the engine. For these purposes, there are two types of engine manifold. 1. Intake manifold and 2. Exhaust manifold
An intake manifold is a complex structure of pipes with one input end and several output ends. The intake manifold is also known as the inlet manifold. As the name suggests an intake manifold is used to deliver the fluid into the cylinder block via an inlet valve. The fluid entering the diesel engine is air and the fluid entering the petrol engine ...
The exhaust manifold is a complex structure of tubes with several input openings and one output opening. These are used to remove the exhaust gases out from the engine via exhaust/outlet valves. It allows the burnt gases containing carbon and other chemical toxins to vent out from the engine to the silencer of the vehicle.
The exhaust gases leaving from each cylinder of a multi-cylinder engine require proper emission without generation of back-pressure. The input openings of the exhaust manifold are connected to each of the cylinder blocks. The exhaust gases are collected by each opening and then are released through a single output tube which is connected to the sil...
Leakage is a common problem with the exhaust manifold.Due to excess heat Corrosion may occur.Results in the noisy operation of the engine.- Exhaust Manifold. Exhaust gases leaving the engine first travel through the exhaust manifold. The manifold collects the exhaust gases from the individual ports in the engine’s cylinder head, then routes those gases to the rest of the exhaust system.
- Catalytic Converter. The catalytic converter is an emissions control device that converts harmful exhaust gases into water, carbon dioxide, and nitrogen.
- Oxygen Sensors. Oxygen sensors measure the amount of oxygen (or the concentration of combustibles) in the exhaust gases leaving the engine. Modern vehicles have both upstream and downstream oxygen sensors.
- Exhaust Pipes. Various exhaust pipes connect the parts of the exhaust system together. The pipes are often made from aluminized or stainless steel to protect against rust and corrosion.
Nov 22, 2019 · So, it blocks the exhaust gases from entering the exhaust pipe. Instead, it forces them thru’ the intake manifold’s passages to reach the exhaust manifold and pipe on the opposite bank. Working: As the engine warms up, more gases pass directly into the exhaust pipe, and less go through the intake manifold passages.
Aug 16, 2015 · An exhaust manifold is not the most efficient design, but it is the most simple, most direct, and least expensive method of routing the engine’s exhaust pulses out of the engine. Most exhaust manifolds do not provide an equal length of exhaust flow cylinder-to-cylinder before the individual cylinder gases combine and enter the exhaust piping.
Feb 13, 2010 · The automobile exhaust manifold and the intake manifold are different engine components, although the auto novice often mistakenly sees them as the same. To complicate things, the intake manifold and the exhaust manifold both process automobile fuel or gases. One (the intake manifold) processes raw fuel, the other (the exhaust manifold ...
