ABSTRACT:
A system for controlling the temperature of gaseous fuel for a coolant cooled engine having a liquid to gas converter where the coolant is adapted to heat the converter. The system includes a gas temperature sensor adapted to measure the temperature of gas exiting the converter and a valve means adapted to regulate the flow of coolant into the converter. A control means determined when said gas temperature falls below a pre-determined value and opens the valve to cause an increased flow of coolant into the converter thus heating it. The system further includes an embodiment where the control means causes the valve means to close only when the temperature of gas exiting the converter is greater than a pre-determined value. A coolant temperature sensor also ensures that the valve can not be completely closed off unless the coolant temperature is above a pre-set value such as 50 degrees Centigrade.
