EXHAUST MANIFOLD DETAILED VIDEO

An exhaust manifold is a system which is used to vent exhaust gases away from an engine. The manifold extends from the cylinders to the exhaust pipe, collecting and moving exhaust away from the engine. Exhaust can be harmful to inhale, making it very important to have a fully functional exhaust manifold; because it can sometimes be difficult to detect an exhaust leak, people may inhale exhaust gases without being aware of it.

When the pistons in the engine reach the exhaust stroke, they push the exhaust fumes up into the exhaust manifold. The manifold consists of a series of pipes which connect to the cylinders and then consolidate in a central large pipe which vents to the exhaust pipe. A series of gaskets are used to create tight seals so that exhaust cannot escape from the cylinders.

One of the most common problems which can arise with an exhaust manifold is damage to the gasket which acts as a seal. In this case, the manifold needs to be unbolted so that the gasket can be removed and replaced. Another issue which can commonly arise is rust, especially in salty environments. If rust eats through the pipes of the manifold, they can start to leak exhaust fumes into the engine compartment. In a car, these fumes can enter the passenger compartment, making people sick.

                                        The 1.2-liter unit, a three-cylinder gasoline engine, can appropriately power a mid-class passenger car with a power output per liter of up to 120 kilowatts (163 hp). Compared to typical gasoline engines in this vehicle class, this is a downsizing by half—with up to 30 percent less fuel consumption.
                                    The technology demonstrator uses cutting-edge technology: forged pistons, two overhead composite camshafts with double camshaft adjustment, four valves per cylinder, direct injection, air-water charge air cooling, cooled exhaust gas recirculation, and cooled lightweight valves. A further technical highlight is the completely integrated intake module, in which the air filter, charge air cooling, noise suppression, three individual throttle flaps, and introduction of exhaust gas recirculation are accommodated. To consistently minimize fuel consumption, frictional loss was also drastically reduced: with the use of innovative coatings on piston pins, piston rings, and cylinder running surfaces.
