Description
Technical Field
The invention relates to diesel engine accessories, in particular to a cold start filter of a diesel engine.
Background
It is well known that diesel fuel forms paraffin crystals at low temperatures near the cloud point. Furthermore, at these cold temperatures, any water in the tank may form ice crystals. To prevent wax or ice blockage of fuel system components (e.g., filters) after a cold start, electric heaters are used in some prior art fuel delivery systems. Because new diesel fuel supply systems also have higher fuel supply and return for system cooling, the prior art electric heaters do not provide adequate de-waxing or de-icing for the increased fuel supply.
Typical temperature controlled recirculation systems for selectively transferring hot fuel to a fuel filter to dewax or de-ice the fuel filter during cold start-up are generally inadequate to dewax or de-ice near the fuel inlet because these devices are locked out of the tank. This is mainly because these devices are relatively large, otherwise they would take up too much space in the fuel tank. Further, these devices are far from the filter, and there are problems such as insufficient dredging of the fuel filter.
