Abstract: PURPOSE: A dual common rail system is provided to prevent the time delay in the compressible fuel transmission from a high pressure fuel pump to a common rail caused by the compressible fluid characteristics and improve the starting response by filling a proper fuel amount in the rail in the case of engine start. CONSTITUTION: A dual common rail system includes main and sub common rails(21,23), first and second valves(24,28), and a high pressure fuel pump(26). The main common rail is mounted at a side of an engine for compressing fuel and sending the fuel to injectors. The sub common rail is mounted at a side of the main common rail to store the fuel partially. The sub common rail has a driving cam(23a) and a piston(23b) to press the stored fuel to be sent to the main common rail in response to a control signal of an ECU(Electronic Control Unit;22) in the case of engine start. The first valve opens or closes a portion between the main and sub common rails under the control of the ECU. The high pressure fuel pump is driven by the ECU to feedback the high pressure fuel into the sub common rail. The second valve sends the fuel back to the sub common rail from the main common rail through a leak off pipe(27) to obtain a target fuel pressure in the main common rail.

Abstract: PURPOSE: An intelligent SOC(System On Chip) designing method and a system for the same are provided to easily design a chip though a prior knowledge on an intellectual property, and to automatically calculate the number of IO pins and power pins. CONSTITUTION: The method comprises several steps. Data on analog intellectual property and digital intellectual property, applied to a specification and a design of a chip to be designed, is inputted(400, 401). The specification of the chip to be designed is compared with that of the analog and the digital intellectual property(402). If there exists an overlapped part of the analog and the digital intellectual property, the overlapped part is output. Otherwise, the intellectual property is modified and a new specification is extracted(403, 404). The extracted specification is applied in generating a circuit, and is combined with the overlapped part, the combined circuit is checked and the numbers of the IO pins and the power pins are calculated(405, 406, 407). The checked circuit and the pin numbers are inputted, and a layout is extracted(408). A mask is produced on a basis of the layout(409).
