ABSTRACT:
A fuel preheating system for an internal combustion engine wherein a preheater includes a body member having defined therein a pair of serially connected, generally parallel bores defining a flow passages through which a flow of fuel may be passed for heating thereof by elongated electric heaters extending within the passages and including a heating element encompassed by helical coils of a heat exchange structure. At least some of the coils of the heat exchange structure define plural tortuous flow paths extending generally axially of the heater. The heat exchange structure has some coils with portions which are maintained in engagement with the heater and other portions which are maintained in thermal conducting and supporting engagement with peripheral wall portions of the flow passage such that a temperature control device carried on an exterior surface portion of the body member operatively interacts with the heaters to control the supplying of energy thereto for heating the fuel passing through the preheater in response to the temperature of the body member.
