  • Engine exhaust emissions monitoring device
    Patent number: 10416042
    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.
    Type: Grant

  • Method for detecting abnormally frequent diesel particulate filter regeneration, engine and exhaust aftertreatment system, and warning system and method
    Patent number: 9482124
    Abstract: A method is provided for detecting abnormally frequent diesel particulate filter (DPF) regeneration. The method includes measuring a pressure drop across the DPF and using the measured pressure drop to calculate a pressure drop based soot load estimate, calculating soot output from an engine model and using the calculated soot output to calculate an emissions based soot load estimate, comparing the pressure drop based soot load estimate with the emissions based soot load estimate, and providing a warning if a difference between the pressure drop based soot load estimate and the emissions based soot load estimate exceeds a predetermined.
