What are the main items tested in vehicle exhaust emission inspections?
1 Answers
Vehicle exhaust emission inspections primarily test for CO, HC, and smoke opacity in motor vehicle exhaust. Below is an introduction to automotive exhaust pipe knowledge: 1. Definition: The automotive exhaust bellows, also known as the flexible exhaust pipe, is installed between the engine exhaust manifold and the muffler. It creates a flexible connection for the entire exhaust system, serving to reduce vibration and noise, facilitate installation, and extend the lifespan of the exhaust muffler system. 2. Material selection: Ferritic stainless steel has a small thermal expansion coefficient, high thermal conductivity, excellent resistance to high-temperature oxidation under repeated heating and cooling conditions, and good corrosion resistance.
