It is very important to supply the diesel fuel from fuel tank to combustion chamber in the case of cold start procedure. the paraffin hydrocarbons are easily solidified at low fuel temperature and it can be blocking the fuel supply to the high pressure fuel pump. In order to reduce the fuel crystallization (Waxing), it have been used to develop not only cold flow additives but also the proper mounting design of fuel filter. Block heater in the fuel filter assembly have been also contained to improve the cold start and prevent blocking the fuel supply in Common Rail Direct Injection System. Cold flow evaluation test standards, however, is not proposed in diesel fuel supply system to predict the cold startability in diesel vehicle. Due to researching the cold flow parameters and evaluating cold flow performance, we suggest the cold flow evaluation test procedure in diesel vehicle.
