The three-way catalytic converter is a metal device installed in the exhaust system of a vehicle. Its purpose is to reduce the pollutants released into the atmosphere when the internal combustion engine is running. They are made of precious metals, including platinum, palladium and rhodium.Although it was first introduced to the U.S. market in the 1970s due to EPA requirements. However, other countries began to pass laws mandating installation. That's because three-way catalytic converters have done an excellent job of reducing pollution in cities like Los Angeles, which have a serious "smog" problem.

The muffler is an important structural element of the exhaust system, without which the operation of a modern car is simply impossible. A car muffler has the following main functions.

Many attentive riders will notice that many supercars, modified cars and racing cars will spit fire from their tails when shifting gears, cornering or even braking, and they will make a bursting sound, which is very shocking. Someone can't help but ask: What is the principle of the rear end of the car? Does breathing fire harm the car? Most importantly, will my family car spit fire?

Friends who are familiar with car modification know more or less about the knowledge of exhaust tail pipes. Although the exhaust pipe at the rear of the car looks like a small part, its image will affect the appearance of the entire car.

Why do so many people love "sports cars" enthusiastically, and want to come to "cool, chic and expensive" can briefly summarize the reasons.

The muffler is an integral part of the vehicle exhaust system. It has two main functions: to adjust and reduce the noise of the exhaust system, and to help filter the exhaust gas in the engine. When your muffler is operating normally, it may not attract your attention, but you cannot ignore it because it is not in your daily sight.

With the increasing prosperity of many emerging markets, people have higher and higher expectations for personal travel. At the same time, the density of vehicles in global cities is gradually increasing. LMC Automotive estimated in 2017 that there are about 1 billion cars on the roads in the world, and this number may reach nearly 1.2 billion by 2018; Trend Force said that although the auto market has gradually weakened since 2018, plus due to the severe impact of the epidemic in 2020, the stocking kinetic energy of major module factories is obviously insufficient. However, the global auto market is recovering in 2021.
