Advantage That Can Simulate Actual Vehic
Advantage that can simulate actual vehicle operating conditions, with four advantages: first test cycle includes idle, acceleration, constant speed and deceleration of various work conditions, to reflect the actual driving of vehicles when emission characteristics; second is that it is transient condition, to overcome the old methods can not detect a problem with oxygen sensor EFI car out of control
Thereby increasing the exhaust airfuel ratio caused by defects in the sewage; Third, high detection accuracy, false positives rate was only 5 The following; Fourth can detect carbon monoxide, hydrocarbons and nitrogen oxides three kinds of pollutants, and to g km that is conducive to urban vehicle pollution emissions statistics, motor vehicle pollution control in urban development planning has practical
Significance . Reporter has learned that Beijing in the implementation of Simple Transient method, the test field on the vehicle exhaust testing commissioned a rigorous management. Beijing Municipal Environmental Protection Bureau has developed inspection system, the establishment of a database of vehicle emissions were seized, and motor vehicle exhaust gas detection field test line to install a video monitoring system.
