What are the motor vehicle exhaust testing equipment?

Simple working condition method like C T machine simple working condition method is to use professional equipment to simulate the actual constant speed driving condition of the car on the road without moving the position, and through the instrument settings, give the car The corresponding loading amount simulates the state of the car when loading cargo or climbing a hill, and then detects the car's exhaust emissions at this time. The original "double idle method" used in the test only conducts exhaust gas detection under two conditions: low idle speed with no fuel in neutral and high idle speed with fuel in neutral. However, the car does not start, which leads to insufficient engine combustion and is at idle. in loading status. The exhaust emission results detected in this way are definitely quite different from the actual driving conditions on the road. The simple working condition method is used to simulate actual driving conditions for detection, which is more scientific than the original double idle speed method, and the detection results are closer to the actual situation. The original idle speed detection method is like a stethoscope; while the simple working condition method is more like a CT machine, which can not only detect the real data of the vehicle's exhaust emissions while driving, but also diagnose the current problems of the vehicle, which is targeted. to perform repairs.
