An Investigation of Diesel Odor in an Air Aspirated Spray Burner and a CFR Diesel Engine

Diesel Exhaust Odor and Irritants: A Review

“…Marshall and Seizinger 35 found odor level increases at either high or low loads for mid-and high-speed ranges, and both the Lesley study and the Marshall study found that an oxidation catalyst in the exhaust reduced odor levels. Reading and Greeves 24 found no consistent speed and load trends with two direct injection and two indirect injection engines; and Ingram, 31 Petrow et al, 36 and Petrow and Cernansky 37 found little effect on odor intensity except during extreme operating conditions when tests using small direct and indirect injection engines were conducted. quenching.…”

Comparison of diesel engine exhaust using chromatographic profiling techniques

“…The effect of engine load or air to fuel ratio (A/F) can be examined by using the AVL data where engine load was varied. As the load increases (A/F ratio decreases), the amount of fuel delivered to the engine increases and the level of odor might be expected to increase (11), although consistent behavior is not necessarily 192 Environ.
