Are Cold Filter Plugging Point and Cloud Point reliable enough to prevent cold-start operability problems in vehicles using biodiesel blends?
Despite being subjected to tight sustainability restrictions in the last decade (Directives 2009-28-CE, 2015-1513-CE, and EU-2018-2001), the use of biodiesel in compression ignition engines is still increasing in the European Union. As known, one of the main drawbacks of biodiesel is cold flow behav...

Despite being subjected to tight sustainability restrictions in the last decade (Directives 2009-28-CE, 2015-1513-CE, and EU-2018-2001), the use of biodiesel in compression ignition engines is still increasing in the European Union. As known, one of the main drawbacks of biodiesel is cold flow behavior, along with oxidation stability problems. According to European standards, the Cold Filter Plugging Point and Cloud Point methods are the ones used to ensure diesel vehicle operability in temperate and arctic climates, respectively, within the EU.
