Currently automotive industry is facing bi-fold challenge of reduction in Greenhouse gases emissions as well as low operating cost. On one hand Emission regulations are getting more and more stringent on other hand there is major focus no customer value proposition. Engine blow by gases are one of the source of Greenhouse gases emission from engine. Blow by gases not only consist of unburn hydrocarbons but also carry large amount of oil. If oil is not separated from these gases, it will led to major oil consumption and hence increase total operating cost of Vehicle. In this paper, effort has been taken to develop a low cost closed crank case ventilation with oil mist separation system on diesel engine. For cost effective solution, two different design and configuration of oil mist separation system has been developed Further, engine with two different above said configuration has been tested for blow by gasses and oil consumption measurement on Engine test bed and vehicle to understand the behavior in real environment. Further results has been compare for both configuration and further actions proposed.
