Modern exhaust systems will still be being refined by their particular producers are therefore able to perform additional functions than a couple of years ago. Exhaust systems are designed to discharge current fumes from the engine of the car outside while minimizing noise emission. Their aim is to cut back to a minimum the actual release of harmful for your environment and human health compounds made by burning fuel in the actual engine. They affect both for you to optimize the operation. An exhaust system in the car consists of the next elements: an exhaust manifold muffler exhaust pipe, catalyst, and optionally particulate filtration (DPF), which however is used only in the modern diesel engine designs. The first component of the system is the exhaust manifold, whose task is to get gases from the cylinder next to a common duct as well as turbine inlet nozzle having turbocharged engines. The conduit, which discharges the exhaust gas through the turbine, or directly from the actual collector is disposed so. lambda probe, which is the composition of the exhaust gas sensor. Using the signal through the microprocessor involved in motor control such adjust the fuel metering exhaust gas to the optimal, or even close to that level. Another device is area of the exhaust system, which in common parlance is referred to as a catalyst. Its aim is to vary the poisonous gases, which include carbon monoxide, hydrocarbons and nitrogen oxides inside neutral carbon dioxide, water vapor and nitrogen propane. This occurs due carried out chemical reactions which occur inside exhaust gas. The next segments of the system are ordinary pipes and silencers which are connected to the total inside series. Today there are being used two types of silencers, namely the absorption silencers in addition to chamber. The former are liable for high frequency attenuation involving sound, and the chamber mufflers have the effect of suppressing low frequencies. It is possible to employ a combination of both dampers together. In diesel engines, the latest generation, as already mentioned, is used diesel particulate filtration, the so-called. DPF. It is a extremely interesting device, whose main task is to capture from flue gases very harmful particles. By its specific design DPF are able to self-cleaning, and therefore the large contamination of the filter unit motor control dispenses an additional fuel quantity, so that the temperature rise inside filter and immediate getting rid of out carbon blacks that have accumulated there. Such a system allows an extremely long service life of the filter, without the need with regard to removal and cleaning this manually, or replacement.
