Modern exhaust systems are still being refined by their producers are therefore able to perform far more functions than a several years ago. Exhaust systems are designed to discharge informed fumes from the engine with the car outside while reducing noise emission. Their aim is to reduce to a minimum this release of harmful to the environment and human health compounds created by burning fuel in this engine. They affect both to be able to optimize the operation. An exhaust system within a car consists of the next elements: an exhaust manifold muffler harrow pipe, catalyst, and optionally particulate filtration system (DPF), which however is used only within a modern diesel engine models. The first component with the system is the harrow manifold, whose task is to recover gases from the cylinder adjacent to a common duct or maybe turbine inlet nozzle along with turbocharged engines. The conduit, which discharges the exhaust gas through the turbine, or directly from this collector is disposed and so. lambda probe, which is the composition with the exhaust gas sensor. Using the signal through the microprocessor involved in motor control so adjust the fuel metering exhaust gas towards the optimal, or even close to that level. Another device is section of the exhaust system, which in common parlance is named a catalyst. Its aim is to switch the poisonous gases, which include carbon monoxide, hydrocarbons and nitrogen oxides inside neutral carbon dioxide, water vapor and nitrogen propane. This occurs due performed chemical reactions which occur inside exhaust gas. The next segments with the system are ordinary pipes and silencers which can be connected to the total inside series. Today there are utilized two types of silencers, namely the absorption silencers in addition to chamber. The former are liable for high frequency attenuation regarding sound, and the chamber mufflers have the effect of suppressing low frequencies. It is possible to employ a combination of both dampers at the same time. In diesel engines, the latest generation, as already mentioned, is used diesel particulate filtration system, the so-called. DPF. It is a very interesting device, whose main task is always to capture from flue gases very pollutants. By its specific design DPF are able to self-cleaning, and therefore the large contamination with the filter unit motor control dispenses one more fuel quantity, so that the temperature rise inside filter and immediate using up out carbon blacks who have accumulated there. Such a system allows a really long service life with the filter, without the need intended for removal and cleaning the item manually, or replacement.
