Diesel Exhaust Odor and Irritants: A Review

“…Some researchers believe that engine speed is not an important parameter; 24 -29 ' 30 however, engine studies by Ingram 31 and passenger car studies by Springer 22 and Springer and Stahman 32 showed opposite trends and thus indicated that odor may not be a predictable function of power. It was thought that the high odor levels at no load, which can be accentuated at high speeds by misfire, could be minimized by advancing the injection timing at light loads to prevent misfire conditions.…”

“…Springer and Stahman, 32 Springer, 22 Hare, 42 and Such 10 report much higher odor levels for acceleration and deceleration transients than for steady state conditions. This behavior is also shown in Tables I and II.…”
