Abstract (en)
[origin: DE102006022357B3] The process involves permanently measuring a gas pressure (P) and gas temperature (T) in a fuel tank (2) of a motor vehicle. An actual vapor pressure of an integral part of a compressed natural gas mixture, e.g. methane, ethane, propane and butane, is determined from the measured temperature and the measured gas pressure in the fuel tank. The actual composition of the gas mixture is determined by an algorithm under consideration of actual fuel consumption during dropping of the vapor pressure of the integral part of the gas mixture in the fuel tank. An independent claim is also included for a device for the determination of the composition of a gas mixture of a fuel tank.
