Claims17
1-16. (canceled)
A vehicular fluid injection system comprising:
- a storage tank;
- an injection line;
- a heating system, wherein the heating system comprises at least one electrical heating element in the tank powered by a power source;
- and
- a voltage converter positioned between the power source and the at least one heating element.
A controller for a vehicular fluid injection system including a tank including at least one heater,
- the controller being an electronic control unit (ECU) integrating a voltage converter configured to provide the heater with a substantially constant voltage over at least a portion of a power range supplied by a battery of the vehicle.
A method for heating at least one part of a vehicular fluid injection system including a tank, with at least one resistive element in the tank receiving an electric current from a power supply, and in which a voltage convertor is positioned between the power source and the at least one heating element, the method comprising:
- providing the at least one resistive heating element with a substantially constant voltage over at least a portion of the power range supplied by the power source.
