Exhaust Tips: The original purpose of the exhaust system was to safely route exhaust gases from the engine so that they could be eliminated into the environment while providing attenuation of combustion noise. However, exhaust gas contains components that are harmful to human health and/or the environment. As a result, the emission levels of these exhaust gas components became regulated. Since regulated emissions levels are often much lower than the levels that can be achieved through in-cylinder control measures, exhaust gas must be treated after it leaves the engine. Thus, while exhaust systems continue their original functions, they have evolved into one of the important elements used for pollution control and reduction in modern engines.
The exhaust system is usually connected to an exhaust manifold, which collects exhaust gases from the exhaust ports of the engine cylinders. In light-duty applications, catalytic converters and diesel particulate filters (DPFs) can be mounted in a close-coupled position to the exhaust manifold or in the underfloor position. The choice of location is determined by space availability and the desired temperature profile, with the closest coupled location providing exposure to the highest possible exhaust gas temperature.

Design Criteria

The exhaust pipe must be carefully designed to carry toxic and/or harmful gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with toxic exhaust gases such as hydrocarbons, carbon monoxide and nitrogen oxides if they are not properly vented. Also, the exhaust gases from most types of machines are very hot. The pipe must be heat resistant, and it must not pass through or near anything that could burn or be damaged by the heat. And A chimney serves as an exhaust pipe in a stationary structure. It is important for an internal combustion engine to have the exhaust system “tuned” (see tuned exhaust) for optimum efficiency. Also, it should meet the regulation norms made in each country. In China, China 5; in European countries, Euro 5; In India, BS-IV, etc.,

Exhaust Tips: A Working Exhaust System

After the fourth cycle of the combustion engine, exhaust gases are generated. The exhaust manifold is connected to the engine and is made in such a way that it has pipes leading to all the cylinders. It has only one output. The manifold collects all the exhaust gases from the different chambers at the same time and pushes them through a single pipe. The opening and closing of the exhaust manifold are controlled by a poppet valve. After the exhaust gases are collected they travel through piping to the catalytic converter. Stock piping is made in such a way that they can cut down on the cost of the car. So they have unnecessary tapers which affect the exhaust gas pressure and can cause back pressure which results in loss of performance. We’ll discuss this after we finish the ‘Exhaust System Job’.
An oxygen sensor is used to check the amount of oxygen in the exhaust gas. Too much oxygen means the car is not using enough fuel and too little oxygen means too much fuel is being used. This data is transferred to the TCU and it alters the fuel delivery accordingly.

Exhaust system tuning

Aftermarket exhaust parts can increase peak power by reducing the back pressure of the exhaust system. These parts can sometimes void factory warranties, although EU Block Exemption Regulation 1400/2002 prevents manufacturers from rejecting warranty claims if aftermarket parts match the quality and specifications of the original parts. So Many automotive companies offer aftermarket exhaust system upgrades as a subcategory of engine tuning. This is often quite expensive as it usually involves replacing the entire exhaust manifold or other large components. However, these upgrades can significantly improve engine performance by reducing exhaust back pressure and reducing the amount of heat that escapes from the exhaust in the under-bonnet area. This lowers the under-bonnet temperature and consequently lowers the intake manifold temperature, thereby increasing power. It also has the positive side effect of preventing heat-sensitive components from being damaged.
Backpressure is most commonly reduced by replacing the exhaust manifolds with headers. Which normally have smoother bends and wider pipe diameters. Exhaust heat management helps reduce the amount of exhaust heat coming out of the exhaust pipe and components. A major solution for aftermarket upgrades is the use of a ceramic coating applied through thermal spraying. This not only minimizes heat loss and reduces back pressure, but also provides an effective way to protect the exhaust system from wear and tear, thermal erosion and corrosion.

Exhaust Tips Exhaust System

Exhaust Tips: An exhaust system is a set of piping used to carry away exhaust gases from a controlled combustion inside a motor engine. And The burnt gas from inside the engine is known as the “exhaust”. The exhaust system consists of two operating components. The first component is related to the removal of exhaust gases from the cylinders. This occurs when a pulse of hot gas is released from the cylinder and into the header primary tube. The second component is the speed of the pressure wave. The variation obtained in the port when the exhaust valve is opened. By manipulating these pressure waves occurring in the second component. The cylinder in the first component can be cleared to allow the flow of fresh charge.
When the exhaust valve in a four-stroke piston engine opens, the pressure in the cylinder will be above atmospheric pressure. And the pressure at the valve in the exhaust port is near one bar (atmospheric). The rapidly changing pressure difference across the valve aperture allows exhaust gas to flow through the opening. And this causes the pressure behind the valve in the port to rise rapidly. Since the velocity of the exhaust gas flow at any point is proportional to the pressure gradient and the cross-sectional area at that point. Small changes in the header can increase the velocity at a given RPM.
If the diameter of the header is too small. It will result in reduced gas flow, increasing the pressure gradient. This situation can cause the tuning gain to be offset. Therefore, the selection of tubing diameter is very relevant in designing the exhaust system. The exhaust pipe needs to be designed in such a way that it carries toxic and other gases
