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.The electronic control unit (ECU) controls the EGR valve (4) to allow the exhaust gas to enter the intake manifold. On turbocharged engines, the control of the exhaust gas flow is also done by means of the throttle (5) which, when closed, lowers the pressure in the intake manifold and facilitates the flow of gases from the exhaust manifold.
May 14, 2024 · Clean EGR tube when experiencing rough idling, decreased fuel efficiency, or engine knocking. Replace if the tube is damaged, causing engine performance issues or persistent exhaust leaks. Consult a mechanic for inspection and accurate diagnosis before deciding to replace the EGR tube. Regular maintenance prevents costly repairs and ensures ...
Feb 25, 2024 · The exhaust gas recirculation (EGR) tube diverts gases from the exhaust manifold through the EGR system for burning in the combustion chamber. The symptoms of a faulty EGR tube are rough idling, stalling, knocking sounds, and an illuminated check engine light. While the EGR tube rarely clogs up, the ports leading to the throttle body can get ...

The system consists of an exhaust manifold, catalytic converter, O2 sensors, exhaust pipes, a muffler, a resonator, a tailpipe, and other miscellaneous components (e.g. gaskets, heat shields, and hangers). The leaking exhaust system can expose you to high amounts of carbon monoxide. An obstructed exhaust system can also create back pressure ...
