Dimensions of Diesel Fuel Performance: Design, Depressants, and Response 660371
The ability of a diesel vehicle to utilize the improved cold flow properties imparted by pour depressant additives depends upon fuel system design and fuel type. The most critical part of the diesel fuel feed system is the suction filter or screen. Pour point depressants, when used in responsive fuels, delay blocking of this filter by wax. In a well-designed system, depressants extend the warmup period sufficiently to permit continued operation. At the threshold temperature for unsatisfactory operating conditions, the extra margin provided by depressants can be all important.
