  • Patent number: 4934330
    Abstract: The invention utilizes a closed-loop type fuel heating system which will simultaneously and continuously heat the diesel fuel in both tanks as found on all tractor trailers. The purpose of heating the diesel fuel is to prevent fuel clouding, waxing and ice formation in the fuel lines. Waxing is known to cause sticking of the fuel injectors. Appropriate valving and a control switch are included in the system to permit the heating system to be turned off in the warmer months when there is no possibility of the ambient temperature falling below thirty-two degrees Fahrenheit. Additionally, appropriate valving is provided to permit the heating source to be cut-off in the event that a leak in the heat exchanger should develop. In order to withstand the effects of vibrating, applicant has provided a multi-coil heat exchanger made of stainless steel.
