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 on customer value proposition.In engine emission the blow by gases are one of the source of greenhouse gases from engine. Blow-by gases not only consist of unburnt 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.Considering the above challenges, effort taken to develop a low-cost closed crankcase ventilation with oil mist separation system on diesel engine. For cost-effective solution, two different design and configuration of oil mist separation system 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 compared for both configuration and further actions proposed.
