exhaust system is designed to remove the products of combustion of the engine, and output them to the environment.This must be ensured a reduction in the noise pollution to acceptable limits.As with any other set of devices, the system consists of several basic components, such as exhaust valve and the channel, the muffler, the resonator, and connecting tubes and collars.The exhaust system has a simple and clear principle - waste gas coming through the pipeline in the silencer, and then in the main, with maximum decreases as the noise level, and the concentration of harmful substances.Of interest is the internal structure of the muffler.The latter consists of a plurality of dampers and partitions, made in one-piece body.Chess order of all these "obstacles" in the way the products of combustion contributes to a significant loss of speed.As a result, the output is a so-called "soothing" gases which subsequently dissolve in the atmosphere.
For example, thanks to this device are delayed and sent back many harmful compounds (nitrogen oxides, hydrocarbons, carbon oxides).Let's see some more recovery system of nitric oxide into the intake manifold.The main reason for the formation of compounds - a high temperature in the combustion chamber.Reducing the concentration of the substance can be effected by lowering the working temperature.The most simple and effective to implement it by returning a portion of the educated emissions.Such exhaust gas recirculation reduces the temperature of combustion of the fuel mixture, but the composition of the latter, and the ratio of substances remain unchanged.Moreover, oscillation may assume cardinality indicators neznachitelnym.Sistema Exhaust many current models of cars comprises in its catalyst structure, which is designed for neutralization and purification of exhausts.
main types of malfunctions of the vehicle system can be called the increase in the noise level and increasing the concentration of harmful substances emissions.The exhaust system due to its low position with respect to the earth's surface can be partially or completely damaged.In addition, a trip on uneven areas with a high probability can lead to a breach of the density of the connecting portions.All of this entails the loss of integrity of the system and, consequently, an increase in noise pollution from your car.In turn, the negative change of the exhaust gas mixture may be the result of incorrect settings of control systems or pollution discharge devices.
exhaust system for long and effective use imposes certain requirements for operation: connecting pipes, resonator and muffler must not be in direct contact with the other structural elements of the vehicle.This precaution will provide not only keeps your tools Exhaust, but also will protect neighboring system.
