Spare parts for your VW exhaust system

CONSTRUCTION OF THE VW EXHAUST

Depending on the engine, the exhaust system can consist of one or two strands. The catalytic converter and muffler are connected by pipes and vary according to engine power and type. It is important to note that engine performance is not affected by exhaust back pressure. The entire system is connected to the sub-floor by flexible suspension elements. Vibrations and mechanical stress on the vehicle can even cause the system to touch the ground. Which can lead to a problem and result in the replacement of certain spare parts. Another problem is corrosion. This occurs after hot exhaust gases condense in cold places. The positioning of the component and mounting brackets plays a major role in soundproofing. Because in addition to engine noise, the exhaust system itself can also produce noise through vibrations and pass them on to the body. However, engine noise is mainly muffled by mufflers in the exhaust system.

SOUND INSULATION

Every VW produces exhaust noise. They are created by the gas ejection from the cylinders. Of course there are fans of this noise who love it especially in sports cars. However, the noise at the tailpipe must comply with certain EU regulations. That is why silencers are used. These minimize the noise by reducing the sound energy of the exhaust gas. Absorption and reflection of the sound are two ways to do this. Reflection silencers work by placing tubes in chambers that prevent sound from spreading. Exhaust gases are divided and spread over different long pipes. According to this, waves can self-level each other after being deflected or repelled. Absorption silencers use porous material (glass fibers, rock wool) that absorbs sound waves. This transforms sound energy into heat. Exhaust flow can be easily routed through tubes in the muffler and sound is picked up through small holes in the material. Reflection attenuates mid and lower frequencies. That is why one uses combined reflection-absorption systems that serve several frequencies. All processes usually take place in the silencer, but there are also other sound-damping elements that can help. Resonators, catalytic converters and exhaust flaps can minimize frequencies with a high interference factor.

LAMBDA SENSOR

As the name suggests, the lambda probe is a sensor for the oxygen concentration in the engine. This part regulates the exhaust emissions of diesel, petrol and gas engines. Every modern petrol engine runs at an optimal ratio of air and fuel. The mixing ratio fluctuates around the value λ = 1, at which complete combustion is achieved. The lambda probe measures the residual oxygen content in the exhaust gases and can thus determine the mixture ratio. The residual oxygen content is compared with the oxygen content in the air. With a result of λ < 1, the mixture composition is rich, i.e. the mixture had more fuel and too little air for ideal combustion. Conversely, at a value λ > 1, the mixture is lean, i.e. low in fuel. The lambda probe part is attached to the catalytic converter. The value is communicated to the engine control unit as an electrical voltage. If the mixture is lean, the quantity of fuel injected is reduced; conversely, if the mixture is rich, it is increased. Two lambda sensors can be installed in a vehicle for perfect exhaust gas values. One in front of the cat - control probe and one after the cat - diagnostic probe. Thus, the diagnostic probe checks whether the control probe is working properly.

VW- GERMAN BRAND QUALITY WITH A GREAT TRADITION

The first VWs were designed by Ferdinand Porsche in the 1930s. They carried their most important function in their name: They should be simple vehicles at a reasonable price, which should grant the normal people a new form of mobility and freedom. Mass production began at the end of the 1930s, and even after the end of the Second World War VW was able to recover from political influence and become a manufacturer of passenger cars for the general public.
