Summary:

A new electronic sensor has been developed to measure the time-resolved concentration of carbonaceous particulate matter (PM) emitted in engine exhaust. One application of the sensor could be to provide cycle-resolved feedback on the carbonaceous PM concentration in the exhaust to the engine control unit (ECU), thereby enabling real-time control of engine operating parameters to lower PM emissions. Another promising application is to monitor the performance of particulate traps. The sensor was tested in exhaust flows from a single cylinder diesel engine and from a steady-state acetylene diffusion flame in a flow tunnel. Steady-state engine measurements were made at constant speed and variable load, and transient measurements were performed during engine start-up and accelerations. The sensor response was compared with an opacity meter and with gravimetric filter measurements. The output of the sensor compared well with exhaust opacity for the transient measurements and to filter mass loading for the steady-state tests. A correlation was developed between the sensor signal and the particulate mass accumulated on filter papers
