It is made up of\u00a0a series of chambers and pipes, begins at the engine and extends to the very back of the vehicle. The vast majority\u00a0of vehicles have 4 cylinder engines with a single exhaust\u00a0running the length of the vehicle. However high performance vehicles\u00a0such as V8’s can have twin\u00a0exhausts as shown in the image below. <\/a> <\/p>\n The main culprit for exhaust damage or wear is rust and it can cause a multitude of problems. \u00a0Depending on the severity it\u00a0can lead to complete exhaust failure or structural damage. Did you know? Going on several short journeys in your vehicle\u00a0can accelerate exhaust erosion. After a short drive the water vapor cools and turns back into a liquid\u00a0leading to a higher chance of rust formation.<\/p>\n 1. Exhaust manifold<\/strong> Exhaust manifolds are located on the engine of a vehicle. Their function is to collect the exhaust gases from the engines cylinders and guide it through the rest of the exhaust system. It ensures that the Common Problem<\/em>: Exhaust manifolds are prone to damage\u00a0from one of two things. The first is the exposure to cycles of extreme pressure and heat. The manifold then becomes\u00a0so worn that it is unable to withstand the heat and cracks begin to form. Cracks can develop into small holes causing complete failure. The second reason is when the exhaust system hangers or mountings<\/a>\u00a0break and the\u00a0exhaust manifold is put under extra pressure that it is not designed for.<\/p>\n 2.\u00a0Oxygen Sensor<\/a><\/strong> These sensors are normally located on either side of the catalytic converter. Their function is to measure the amount of oxygen in the exhaust system.\u00a0It uses this information to add or reduce fuel in the combustion process\u00a0to Common Problem:<\/em> Oxygen sensors can become worn and give\u00a0less accurate measurements over time. Modern vehicles\u00a0will have an alert on the dashboard when the sensor is malfunctioning. Replacing them can save a considerable amount of money in the long run as oxygen sensors are vital\u00a0for fuel economy.<\/p>\n \n 3.\u00a0Catalytic Converter<\/a><\/strong> Catalytic converters are found between the manifold and the silencer. Their function is to convert pollutants in the exhaust fumes to less harmful ones.\u00a0 Common Problem:\u00a0<\/em>Catalytic\u00a0converters can become blocked or choked. The symptoms of a blocked catalytic converter are\u00a0a noticeable lack of power, a sense of heat from the floor of the vehicle\u00a0or a smell of sulfur (or rotten eggs).<\/p>\n 4.<\/strong> Diesel Particulate Filte (DPF)<\/a><\/strong> Their functions is\u00a0to remove the particulate matter or soot from the exhaust gas\u00a0of diesel engines. Common Problem:<\/em>\u00a0Due to their purpose DPF’s can become clogged over time and in extreme cases may need to be replaced. DPF’s go through a process called regeneration which aims to clear out the soot but in order for it to go through this process specific driving conditions have to be met. There is a danger that it can become clogged beyond the ability of the engine managements ability to clean\u00a0it.<\/p>\n Driving diesel vehicles\u00a0short distances without the engine heating up sufficiently is likely to\u00a0lead to clogged DPF problems. To prevent this from happening additives such as the JLM Diesel DPF ReGen Plus<\/a><\/strong>\u00a0can be added to the fuel. It is ideal for use on vehicles that are often driven on short journeys or around towns. Alternatively a long drive on a\u00a0motorway while holding the engine at higher RPM (i.e. use a lower gear than normal whilst sticking to the speed limit) can help it to begin the regeneration\/cleaning cycle. If the DPF is already blocked then the\u00a0JLM Diesel Particulate Filter Cleaner<\/a><\/strong> can be used. Simply add the entire contents of the 100ml bottle to a full tank of diesel. The concentrated formula is extremely effective and is designed to be used when the amber DPF warning light is illuminated on the vehicle’s dashboard. <\/p>\n Muffler<\/a>\u00a0(also known as a Silencer)<\/strong> Mufflers\u00a0are located toward the end of an exhaust system. Their function is to reduce the noise that comes from the fuel combustion process and Common Problem:<\/em> If the silencer is\u00a0damaged it\u00a0will make the vehicle\u00a0sound considerably different or louder. Examining the muffler can help to determine if it’s working correctly. Check for holes or\u00a0rust, if there are signs of rust it may indicate a more serious problem within the muffler. Be careful not to touch an exhaust pipe while it is still hot.<\/p>\n Exhaust Pipes<\/strong><\/a> <\/p>\n The components outlined above are all linked by exhaust pipes and their function is to direct the gas through the various parts\u00a0before it exits from the tail pipes Common Problem: <\/em> As mentioned above<\/a>\u00a0rust is the main culprit when it comes to exhaust damage or erosion. The linking exhaust pipes can become so rusted that small holes form.<\/p>\n Exhaust System Guide & Common Problems<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2657","post","type-post","status-publish","format-standard","hentry","category-uncategorised"],"yoast_head":"\n![\"golfgti113\"](\"https:\/\/www.imagetin.com\/images\/micksgarage-ie\/421a2477-0\/golfgti113_75bf31.jpg\")

<\/a> High performance twin exhaust on a V8 engined car While most of us will only see the tail pipe (the very end) of an exhaust system, the average length of one is about 3 metres and\u00a0consists of 6 main components depending on the fuel it consumes: <\/p>\n\n

Common Problems with the Exhaust System<\/h3>\n
<\/a> New vs Old Rusty Exhaust In rare cases the exhaust pipe can become so eroded or damaged that it will become loose and start dragging on the road. If this happens you should take your vehicle\u00a0to the nearest mechanic or exhaust specialist. If it is not safe to drive the vehicle\u00a0you should ring for road side assistance and\u00a0take care not to inhale any of the toxic fumes. If you hear rattling under the vehicle\u00a0it could mean something has become loose such as a bracket, heat shield or a piece of exhaust pipe. It’s important to get your exhaust system examined if this is the case. Loose exhaust parts or missing brackets can put additional structural stress on the exhaust system and damage other expensive components. We supply a wide range of exhaust mounting kits<\/a>\u00a0to repair such damages. <\/p>\nExhaust Components<\/h2>\n
toxic gasses do not enter inside the vehicle\u00a0to the passengers. <\/p>\nget\u00a0the best fuel to air mixture. <\/p>\nIf one was fitted to your vehicle\u00a0originally, a catalytic converter is required by law and it will fail the NCT or MOT if it is removed. <\/p>\nThe introduction of the\u00a0Euro 5<\/a><\/strong>\u00a0emission regulation\u00a0in 2009 meant that diesel vehicles\u00a0would require the fitment of a\u00a0DPF to meet the new emission standards. <\/p>\ndirect the fumes out of the exhaust system.
