||The emissions from heavy duty Diesel crankcases contain a number of hazardous compounds. Research has discovered some of them and it may be possible that there are some that have not yet been quantified. Nitrosamines (a potent carcinogen in animals and probably also in humans) are emitted from engines using fresh oil. These emissions seem to be a function of the type of oil used and some engine parameters such as crankcase flow rate of NOx compounds. Used lubricating oil has been shown to contain carcinogenic compounds such as benzo-a-pyrene. It has also been shown to be mutagenic. Therefore it can be concluded that the particulate portion of the crankcase effluent stream may start out after an oil change at a level containing few carcinogenic compounds but the level of these compounds increases with time. In conclusion, crankcases emit a variety of hazardous chemicals and evaluation of the costs and benefits of the control of these emissions should be seriously considered.
