    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.

    Abstract: PROBLEM TO BE SOLVED: To certainly start an engine. SOLUTION: When the engine does not completely explode within a predetermined time after engine start by driving a starter motor and a fuel pump (S100 to S104), the driving of the fuel pump is stopped for a predetermined time (for example, 3 sec) and is restarted after a predetermined time (S106 to S110). The driving of the fuel pump is temporarily stopped because repeating of driving and stopping of the fuel pump frequently allows removal of a foreign matter even when the foreign matter intrudes into the fuel pump to cause a starting failure. Thus, the fuel pump is normally driven, so that the engine is started further certainly. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a cooling device for an internal combustion engine which prevents a sudden temperature fall of cooling water circulating in the internal combustion engine. SOLUTION: A warming-up control means 50 controls a pump 38 for a heat accumulation tank and a three-way selector valve 30 and warms up the engine by supplying the hot cooling water pooled in the heat accumulation tank 36 to the engine 10. When temperature of the cooling water returned from a heater core 44 to the engine 10 is below that of the cooling water discharged from the heat accumulation tank 36, the warming-up control means 50 controls the three-way selector valve 30 and adjusts a flow rate of the cooling water circulating through the heater core 44 and the engine 10 below a predetermined flow rate.

    Abstract: PROBLEM TO BE SOLVED: To improve judging accuracy when the existence of failure of a switching mechanism for switching an exhaust passage is judged, in relation to an exhaust passage switching device for an internal combustion engine. SOLUTION: A switching mechanism 70 is disposed to switch the exhaust passage with a main passage 30 and a bypass passage 32 by leading negative pressure of an intake manifold 14. The switching mechanism 70 is provided with a switching valve 34, a diaphragm mechanism 40, a negative pressure supplying piping 50, and a VSV 52. When the VSV 52 is turned on, negative pressure is supplied to a transformation chamber 44 of a diaphragm mechanism 40, a diaphragm 42 is deflected, and then, the switching valve 34 is closed interlockingly therewith. The existence of the failure of the switching mechanism 70 is judged on the basis of pressure of the negative pressure supplying piping 50 when the VSV 52 is turned on. Before the VSV 52 is turned on, namely, in a condition in which the VSV 52 is turned off, in the case where pressure in the negative pressure supplying piping 50 is not held to the atmospheric pressure, failure judgment of the switching mechanism 70 is inhibited on the basis of pressure of the negative pressure supplying piping 50.

    Abstract: PROBLEM TO BE SOLVED: To check whether or not an intake air pressure compression degree change means is set so as to increase the intake air to a high-pressure compression degree during the cranking of the engine in the internal combustion engine having the intake air pressure compression degree change means capable of changing an intake air compression degree in a cylinder at the time of starting of the engine. SOLUTION: Whether the intake air compression degree is set to a high value or not is judged by the anti-cranking reaction of the internal combustion engine to a cranking by an electric motor. In the anti-cranking reaction, a variation in crank shaft speed in an increasing process by cranking or a magnitude of a cylinder pressure relative to the crank shaft speed are detected.
