Abstract: PURPOSE: A fuel injection timing control method for a diesel engine is provided to keep fuel injection timing by compensating the difference of a fuel temperature and a predetermined temperature in a diesel engine including an EUI(Electronic Unit Injector). CONSTITUTION: For controlling fuel injection timing of a diesel engine, required fuel injection amount and fuel injection timing are calculated depending on a vehicle speed, a cam angle, a throttle valve opened degree, cooling water temperature, intake air temperature and intake air pressure sensed via a traveling state sensing unit(S10). The temperature of fuel is detected by a fuel temperature sensor on a fuel line supplied to an EUI, and an electrical signal is applied to an ECU(Electrical control unit)(S20). The ECU decides if the fuel temperature is included within a range of maximum, minimum and standard temperatures or not(S30). If the fuel temperature is included within the range, the ECU outputs fuel injection timing control signals depending on fuel injection timing mapping data of respective modes is outputted to the EUI(S40). If the fuel temperature is not included within the range, compensatory fuel injection timing control signals are outputted to the EUI(S50). And, fuel injection timing of the EUI is kept uniform and explosion force of an engine is maintained properly in winter. Therefore, the life of the engine is lengthened.

IPC: G11B27/36
Filed: 1997-07-24
Abstract: PURPOSE: A selective recall and preservation of continuously recorded data is provided to enable the effective recording and reproduction of events that transpired before the decis ion to record or reproduce them was made by enabling a human user to select for recall or preserved portions of audio, video or other data that have been continuously recorded on a finite extent of recording medium. CONSTITUTION: Analog audio data are acquired through a microphone, telephone similar transducer or input, converted into digital data at a sampling frequency by an analog-digital converter, and stored sequentially in a circular series of input buffers. In an arrangement typical of personal computers, a peripheral sound card incorporating an analog-digital converter acquires audio signals and stores them sequentially via direct memory access(DMA) in a queue of input buffers allocated by an application program. As each input buffer in turn becomes full, an interrupt signal or a message identifying the particular buffer is generated. When the application program receives this signal or message, the sound data are transferred from that input buffer to acquisition buffers in memory.
