    Abstract: PROBLEM TO BE SOLVED: To provide a heat storage system for dispersing a load on a pump.
    SOLUTION: The heat storage system operates a warm-up pump 18 in a warm-up stroke and does not operate it in a heat storage stroke. Alternatively, in the heat storage stroke, a heater pump 15 is operated to accelerate the collection of hot water. The collection of the hot water can also be accelerated by increasing the rotating number of a circulation pump 3. Since a great load is exerted on the warm-up pump 18 during warm-up stroke, the heat storage stroke is executed by another pump, whereby the operating frequency of the warm-up pump 18 is reduced and the life of the warm-up pump 18 is elongated.

    Abstract: PROBLEM TO BE SOLVED: To provide a vehicular engine warming-up device capable of improving collecting efficiency of warm water, and having a thermal storage system.
    SOLUTION: The vehicular engine warming-up device comprises a heat radiating portion radiating the heat of cooling water, and a heat accumulator 10 storing the cooling water that is warmed up over a specified temperature, in an engine cooling water system. The heat radiation capacity of the heat radiating portion is made to be variable, and when the heat accumulator 10 collects the warm water, the heat radiation capacity of the heat radiating portion is made to be small. The heat radiating portion is a radiator.

    Abstract: PROBLEM TO BE SOLVED: To provide a starting device for an internal combustion engine, suppressing the occurrence of great vibration in the internal combustion engine following wastefully increased pressure in a combustion chamber getting into the first compression stroke after starting the engine in a warm-up completed condition.
    SOLUTION: At starting the engine in the warm-up completed condition, torque to be granted to a crankshaft 9 for cranking is lowered in a certain period from starting the engine to arriving at the top dead center of the compression stroke. Thus, the torque to be granted to the crankshaft 9 is set to be such a value that the rotation of the crankshaft 9 is stopped in the certain period to make an engine speed into zero. When the rotation of the crankshaft 9 is stopped, a time required for releasing a preset amount of gas from the combustion chamber 2 being in the first compression stroke after starting the engine is accurately kept in the period and pressure in the combustion chamber 2 is lowered. Consequently, there is no wastefully increased pressure in the combustion chamber 2 after resuming the cranking.

    Abstract: PROBLEM TO BE SOLVED: To appropriately restrain waste of power in an electric motor while realizing a quick engine starting even at low temperature. SOLUTION: In this device, motoring of the engine 10 is performed by a motor generator (M/G) 11 until a revolution speed reaches a predetermined target revolution speed, and firing is started at a predetermined timing after motoring starting, thereby controlling starting of the engine 10. An increasing degree of the revolution speed of the engine 10 during motoring is monitored, and the target revolution speed is corrected based on the increasing degree. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a crank angle detection device for an internal combustion engine capable of detecting the rotation angle of the crankshaft of the engine more accurately.
    SOLUTION: A crank angle calculating part 38 calculates the estimated value of a crank angle which is the estimated value of the rotation angle of the crankshaft 24 based on a motor angle signal outputted by a motor angle sensor 34 and the rotation ratio set value of the engine 10 which is the internal combustion engine and a starter generator 22 which is a motor. The rotation ratio correction part 40 compares an actual crank angle signal outputted by a crank angle sensor 30 with the estimated value to obtain an error in the value, thereby correcting the set value.
