IPC: H01M6/42
Filed: 2002-07-24
Abstract: <P>PROBLEM TO BE SOLVED: To improve a current detecting accuracy by offset correcting a current detection value by detecting an offset value of a current sensor even during traveling of a vehicle.  <P>SOLUTION: An amount ΔV of a voltage drop of each of cells 1a-1d per predetermined time when only a cell voltage detector circuit 3d is connected to a main battery 1 is stored as a reference value. The amount ΔV of the voltage drop of each of the cells 1a-1d per predetermined time detected by the cell voltage detector circuit 3d is compared with the reference value, and the cell in which both the amount ΔV of the voltage drop and the reference value are equal, is extracted. A rate of the extracted cell occupying in all the cells 1a-1d of the battery 1 is obtained. When the rate is a predetermined rate or more, it is judged that discharging current or charging current does not flow to the current sensor 6, the output of the sensor 6 at that time is stored as the offset value, and the detected value of the discharging current or the charging current by the sensor 6 is corrected by the offset value.  <P>COPYRIGHT: (C)2004,JPO

Title: Improvement of fuel consumption of diesel engine using automatic electrothermal fuel heater, and exhaust emission control device
Inventor: FUJITA TOMIYUKI
IPC: F02M27/04
Filed: 2002-08-27
Abstract: <P>PROBLEM TO BE SOLVED: To improve fuel consumption by spontaneously heating fuel to a constant temperature to make the fuel injected from a fuel injection nozzle into fine particles for promoting fusion with air and increasing fuel efficiency, and simultaneously raising a temperature in a cylinder to further increase fuel efficiency due to its synergistic effect.  <P>SOLUTION: Fuel is transferred from a fuel tank 1 to an automatic electrothermal fuel heater 4 via a primary fuel filter 2 and a fuel flow meter 3, and spontaneously heated and expanded to a constant temperature set by a temperature setter 12 according to a flow rate. Compressed high temperature fuel is injected in a cylinder by a fuel injection nozzle 9. In this case, because an injection pressure is increased more than normal, smaller fuel particles are dispersed so as to heighten a fusing property with air and increase fuel efficiency. Along with perfect combustion, exhaust gas can be also purified. Because the high temperature fuel not used by a fuel injection pump 7 is returned to the automatic electrothermal fuel heater 4 and recycled so as to save electricity required for heating, an economical effect is larger. Therefore, this invention can contribute to resource exhaustive problems and environment improving problems.  <P>COPYRIGHT: (C)2004,JPO
