Abstract: A heating system for liquefied gas fuel supply apparatus is applied to a liquefied gas fuel supply apparatus that causes a vaporizer to vaporize liquefied gas fuel and supplies the vaporized fuel to an internal combustion engine, the heating system including a circulation circuit and a heat insulating container. The circulation circuit circulates a heating medium between the vaporizer and an inside of the internal combustion engine. And, the heat insulating container stores the heating medium. In this case, the heat insulating container is disposed in the circulation circuit.

Abstract: A heating apparatus for a liquefied gas fuel supply system includes a heating unit, a detecting unit and a setting unit. The liquefied gas fuel supply system vaporizes liquefied gas fuel to supply the vaporized gas fuel to an internal-combustion engine. The heating unit heats the liquefied gas fuel before the liquefied gas fuel is vaporized. The detecting unit detects vapor pressure characteristic of the liquefied gas fuel. The setting unit sets an amount of heat to be applied to the liquefied gas fuel on a basis of a detection result by the detecting unit.

Abstract: A first signal generating apparatus generates unit angular signals at predetermined angular intervals, in relation to the revolution of a first rotary shaft. The first signal generating apparatus generates a first reference signal which has a different timing than that of the unit angular signals. A second rotary shaft completes one revolution while the first rotary shaft completes two revolutions. A second signal generating apparatus generates a second reference signal with every revolution of the second rotary shaft. A counting apparatus counts the unit angular signals and stores the counted value, and initializes the counted value every time the first reference signal is generated. An angular detecting apparatus determines whether or not the second reference signal is generated by the second signal generating apparatus. Based on the result of this inquiry, the angular detecting apparatus measures the rotational or angular displacement of the first rotary shaft.
