Abstract
(EN)
The present invention presents a device for calculating the pressure of a fuel tank, for calculating the pressure of a fuel tank to measure the amount of remaining fuel in the fuel tank of a compressed natural gas vehicle comprising the fuel tank, a regulator valve, a fuel rail, and an injector, the device comprising: an ECU for providing an injection flow amount of a fuel being injected from the injector, and an operation rate of the regulator valve; a rail pressure sensor for measuring and providing a rail pressure of the fuel rail for distributing the fuel to the injector; and a fuel amount calculation unit which derives a valve flow amount of the regulator valve on the basis of the rail pressure measured by the rail pressure sensor and the injection flow amount provided by the ECU, and which calculates, on the basis of the valve flow amount and the operation rate of the regulator valve provided by the ECU, a primary-side pressure of the fuel being introduced to the regulator valve, and which calculates the pressure of the fuel tank on the basis of the primary-side pressure.
