Exhaust gas analyzer Exhaust gas analyzer An exhaust gas analyser or exhaust CO analyser is an instrument for the measurement of carbon monoxide among other gases in the exhaust, caused by an incorrect combustion, the Lambda coefficient measurement is the most common. The principles used for CO sensors (and other types of gas) are infrared gas sensors (NDIR) and chemical gas sensors. "Carbon monoxide sensors are" used to assess the CO amount during an MOT test. In order to be used for such test it must be approved as suitable for use in the scheme. In UK a list of acceptable exhaust gas
Exhaust gas been operated for several hours, the amount of emissions can be very high. This occurs for two main reasons: Comparable with the European emission standards EURO III as it was applied on October 2000 In 2000, the United States Environmental Protection Agency began to implement more stringent emissions standards for light duty vehicles. The requirements were phased in beginning with 2004 vehicles and all new cars and light trucks were required to meet the updated standards by the end of 2007. In spark-ignition engines the gases resulting from combustion of the fuel and air mix are called exhaust gases. The
