There are two main critical components of performance exhaust systems for cars which require constant cleaning: diesel particulate filter (DPF) and catalytic converter. These parts are the hot spots of issues related to a car’s efficiency. It has been reported that a lot of cars fail emission tests due to unacceptable conditions of the exhaust.
- The cause of issues on catalytic converter and DPF
Carbon deposits accumulate inside the performance exhaust system overtime. This reduces efficiency and more harmful gases are produced as time goes by. The modern diesel vehicles use DPFs which perform the same function but have the ability to remove and store a huge number of particulate than the converters do. Diesel engines burn up built-up deposits but when the DPF is clogged up, the whole unit will need replacement due to diminished efficiency; and the cost is very high. This problem of catalytic converters and DPFs are worsened by fuels of poor quality.
- Do DIY cleaning products really work
These are additives which contain particular chemicals which enter the exhaust systems to decompose toxic deposits in the catalytic converter or DPF. They are then expelled out through exhaust tips. The cleaning agents have no effects on other sections of the engine. The cheapest products are the most popular and they come in bottles from prominent motor stores and online market. The cost varies depending on quality. The liquid cleaner is poured into the vehicle's fuel tank just the way fuel is filled in. Then the vehicle is driven for around 15 to 30 minutes. The instructions on usage must be followed carefully. You will find these cleaning products in most garages and they tackle all exhaust dirt from fuel injectors all the way to the exhaust tips.
The operational lives and mileage of vehicles vary significantly. As such, the cleaning products are not similar and some may not provide a permanent solution in a single application. Studies show that these additives can reduce toxic emissions by 60% if used four times in a year.
