    Abstract: PROBLEM TO BE SOLVED: To provide a control unit of internal combustion engine that suppresses the vibration generated when the operation of an engine is stopped. SOLUTION: When a predetermined stopping condition holds, an ignition timing of an engine is made to coincide with an ignition timing for maximum torque, and an idle operation with an intake air quantity less than the one during normal idle operation has been performed for a predetermined period of time (Step S120, S130), and subsequently the engine is stopped (Step S140). As a result, when the engine has been stopped, the pressure within a cylinder can be sufficiently lowered, and consequently the vibration generated when the engine is stopped can be suppressed.

    Abstract: PROBLEM TO BE SOLVED: To simplify a device necessary to preheat an engine and more promptly start the engine while preheating it. SOLUTION: A circulation pipe passage 61 forming a circulation passage of a heat exchange medium is provided with a heat storage tank 65 warming and holding the heat exchange medium heated by the engine 22 and a water pump 62 of which rotational shaft is mechanically connected to a crankshaft of the engine 22 for circulating the heat exchange medium inside the circulation pipe passage 61 and driven by rotational force of the crankshaft. When start of the engine 22 is instructed, if engine water temperature from a temperature sensor 23 is below predetermined temperature, cranking of the engine 22 is continued for predetermined time to preheat the engine 22. After the predetermined time passes, fuel injection and ignition are started to start the engine 22. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of the longitudinal vibration of a vehicle when the operating point of an engine is moved from a first operating line to a second operating line. SOLUTION: Based on the varying rotating speed (ne) of an engine, an electronic control unit obtains, in addition to the target torque (te*) of the engine, the target opening/closing timing VT* of an intake valve by a continuous variable valve timing mechanism, the target opening SVP* of a throttle valve by an actuator, and the target ignition timing IT* of an ignition plug (step S302). The values of the target opening/closing timing VT* are obtained by finely setting VT* so that the varying speed of the VT* matches the varying rotational speed ne of the engine. The values of the SVP* and IT* are also obtained in the same manner. COPYRIGHT: (C)2005,JPO&NCIPI

    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.
