  • Electrically heated diesel engine fuel conveying system
    Patent number: 4600825
    Abstract: The invention relates to a system for conveying fuel, preferably diesel fuel, to an engine, in particular a diesel engine. The invention includes a pipe, at least one filter and a fuel pump. At least one heating element is provided on a portion of the area of the surface of the filter and in the path of the diesel fuel for partially melting paraffin deposits of the fuel on the heated portion of the filter surface. The heating element extends over only a portion of the surface of the filter, for example over 0.02 to 20 percent of said surface relative to a diesel engine power of 36 kW to 4500 kW. The heating element may be controlled in response to fuel flow through the filter, the pressure difference between the downstream and upstream sides of the filter, absolute pressure on the downstream side of the filter, or in response to the temperature difference between the temperature of the fuel at points upstream and downstream of the filter.
