摘要:
The present invention relates to a system for detecting the remaining quantity of liquid hydrogen stored in a hydrogen storage device. In this system, the remaining quantity of liquid hydrogen is calculated accurately without being affected by the previous state in a tank. The internal pressure of the tank is detected. A fixed heat quantity is applied into the liquid hydrogen. The pressure in the tank after the application of heat quantity is detected. The volume of phase-transited hydrogen gas is calculated based on the heat quantity applied into the tank. The change amount of pressure in the tank before and after the application of heat quantity is calculated based on the pressure and the pressure. The remaining quantity of liquid hydrogen in the tank is calculated based on the volume of hydrogen gas and the change amount of pressure.

Disclosed is a hydrogen supply apparatus which can mix an odorant with hydrogen gas even at a low temperature and can detect the leakage of the hydrogen gas. The apparatus comprises a gas storage portion which stores hydrogen gas therein, an odorant-addition portion which adds an odorant to the hydrogen gas fed from the gas storage portion, and a temperature control portion which controls the temperature of at least one of the hydrogen gas stored in the gas storage portion, the hydrogen gas fed from the gas storage portion and the odorant.

A start control apparatus for an internal combustion engine which guarantees excellent startability regardless of the nature of the fuel used. In addition, a fuel nature determining apparatus designed to prevent mistakes in the determining of the nature of the fuel. When conditions for beginning the starting of an internal combustion engine have been established, normal start control is performed in order to start the internal combustion engine. After the starting of the internal combustion engine has begun using the normal start control, if the starting is completed within a predetermined length of time, a determination is made that the fuel supplied to the internal combustion engine is of a light nature. If, however, the starting is not completed within a predetermined length of time, a determination is made that the fuel supplied to the internal combustion engine is of a heavy nature. In this case, after a predetermined length of time has elapsed, heavy fuel start control is performed in place of the normal start control so that the starting of the internal combustion engine will be quickly completed. According to the above method, the nature of the fuel is detected before the starting of the internal combustion engine is completed and, when the fuel is of a heavy nature, the start control can be altered to control which corresponds to the nature of the fuel.

An exhaust gas emission control apparatus is provided in an exhaust passage of a hybrid mechanism driven by an internal combustion engine and an electric motor. The apparatus has an adsorbent that adsorbs unburned fuel contained in exhaust gas when the temperature of the adsorbent is lower than a predetermined temperature, and that releases adsorbed unburned fuel therefrom when the temperature is at least the predetermined temperature. When the temperature of the adsorbent is lower than the predetermined temperature, the apparatus controls the hybrid mechanism to delay an increase in the temperature of the adsorbent.
