Investigation of correlation between diesel fuel cold operability and standardized cold flow properties

Abstract

Role of diesel fuel in the mobility is unquestionable despite of diesel scandal. There are several approaches to substitute partially at least it, but in commercial utilization the real alternative is not found yet. Diesel fuel main disadvantage beside the environmental factors is the application properties in cold weather. In the presented research there is an overview and evaluation about the main classification methods of winter properties of diesel. The result is, that CFPP and CP have lower and lower correlation with the newest engine technologies and a new method would be necessary to able to predict the winter behavior of diesel in real conditions. In the paper a specification of a new test equipment is presented.
