A Tapered Element Oscillating Microbalance (TEOM) was used to measure transient diesel particulate emissions. Light duty IDI and DI engined vehicles were tested over the LA4 Drive Cycle. One vehicle, a 1.6 litre IDI diesel engined VW Golf (Rabbit), was also tested over the Japanese 10-mode and European ECE-15 Cycles. Transient particulate emissions were also measured from a heavy duty DI diesel engine tested according to the US Federal Heavy Duty Transient Test Procedure. The TEOM proved to be very flexible, permitting continuous particulate measurements to be made at each of the conditions studied. Particulate mass determined by the TEOM over a complete cycle was generally lower, typically by between 13 and 28%, than that measured using conventional gravimetric filtration procedures. A new calibration technique was devised which improved the correlation between TEOM and gravimetric results.
