Abstract
An exhaust emissions monitoring device includes a pipe adapted to mount to the tailpipe of a vehicle and includes a cable for connecting to the vehicle engine control unit (ECU) and power system. The pipe defines an internal flow passage to allow exhaust to flow through. A plurality of sensors is mounted on the pipe and each sensor extends through an access port formed on the pipe wall to be exposed to the internal flow passage. Exhaust properties and constituents are sensed by multiple sensors for each constituent, there are two or more sensors for each of NOx, temperature, ammonia, particulate matter. The sensors communicate data signals to a processor/data logger also mounted on the pipe.
