Title: State detecting method for car battery
Inventor: TANAKA AKIFUMI
IPC: H01M10/48
Filed: 1993-05-18
Abstract: PURPOSE:To enhance reliability by setting two voltage detecting points between the open circuit voltage of a battery and the constant voltage region of an alternator and detecting the end of service life of the battery when the battery voltage rises through the two detecting points within a predetermined time thereby suppressing the erroneous detection. CONSTITUTION:A car battery BT, an alternator G, an engine E, and a load L mounted on the vehicle are connected with comparators ICA, ICB for detecting VA voltage and VB voltage, respectively. When a power supply voltage LB exceeds the VA voltage, output OA of the ICA goes 'H' to produce a transient current depending n the time constant T0 of a CR circuit 4. Consequently, a voltage is induced across a resistor 4 and the output OC of a comparator ICC goes 'H' within 0.2-0.3sec. When the power supply voltage LB rises to the vicinity of the point VB within the time T0=0.2-0.3sec, output OB of the comparator ICB also goes 'H' and an alarm light LED is lighted. This method suppresses erroneous display thus enhancing the reliability.

IPC: F02B17/00
Filed: 1983-07-29
Abstract: PURPOSE:To improve the ignitability and reduce the energy loss of an engine by injecting fuel in a prescribed time from the latter half of a suction stroke to the compression stroke when the load is light, and at a prescribed time in the former half of a suction stroke when the load is heavy and by reducing the air injection quantity corresponding to the fuel quantity. CONSTITUTION:When the load of an engine is light, the fuel is injected from an injection valve 21 against a sparking plug 20 at a prescribed time in the latter half of a compression stroke, which facilitates the ignition and combustion even the fuel quantity is small. In this time, the suction air to a suction passage 8 is not limited and the pumping loss is reduced. On the other hand, when the load is heavy, the injected fuel is dispersed into the combustion chamber 7 by the air from a suction passage 2 and a swirl control valve 10 is opened and the swirling in the combustion chamber 7 is accelerated, thus the fuel is atomized and vaporized. Moreover, when stratiform air intake is not performed air injection is not required for the atomization and vaporization of the fuel, which decreases the air injection quantity and the energy loss is reduced.
