    Abstract: PURPOSE: To highly efficiently purify components of HC, CO, NOx in exhaust gas of an internal combustion engine by converting total quantity of NOx in the exhaust gas to NOx in quantity to form N2 and H2 O by way of reacting with N2 , NH3 , etc., in proper quantities. CONSTITUTION: An exhaust passage 4 of an internal combustion engine 1 is branched to branch passages 4a, 4b in the downstream of three-way catalyst 11, and a denitrated/oxidated catalyst 15 is provided in an exhaust passage 5 after the branch passages join. An oxidated catalyst 13 is arranged in the branch passage 4a, and a dummy resistor 17 is arranged in the branch passage 4b respectively. Total quantity of NO in engine exhaust is once converted to N2 and NH3 by the three-way catalyst, NH3 in the branch passage 4a is converted to NOx in total by the oxidated catalyst 13. Proportion of exhaust flow rates of the branch passages 4a, 4b is set so that NOx in quantity to react with NH3 passing the branch passage 4b in proper quantities is generated by the oxidated catalyst of the branch passage 4a. NH3 and NOx in exhaust air react with the denitrated/oxidated catalyst after joining, and their total quantity is converted to N2 and H2 O.

    Abstract: PURPOSE:To set an ideal fuel injection timing in the all rotational range of an internal combustion engine, in a fuel injection timing control device for controlling the fuel injection timing to the internal combustion engine provided with a variable valve timing mechanism. CONSTITUTION:It is judged whether the opening timing of an intake valve set by a variable valve timing mechanism is an early opening timing or not (Step 100). When the opening timing is early, fuel is injected after a top dead point when the opening change rate TA of a throttle valve is a prescribed value (x) or more (Step 120) since the level of back blow is large. When the relation between YA and (x) is YA

    Abstract: PROBLEM TO BE SOLVED: To improve comfortableness in a hybrid vehicle. SOLUTION: In this hybrid vehicle 10, an ECU 100 can operate an engine 200 at its lean limit or combustion limit by performing MG1 feedback control.

    Abstract: PROBLEM TO BE SOLVED: To provide a technology capable of preventing hybrid system destruction caused by performing rich spike control. SOLUTION: An internal combustion engine control device is provided for a hybrid vehicle having an internal combustion engine capable of lean combustion and comprising an NOx storage reduction catalyst which holds NOx in exhaust gas and reduces held NOx according to an exhaust air-fuel ratio, and a generator which converts a part of energy generated by the internal combustion engine into electric energy. In idling operation of the internal combustion engine where the rotating speed of the internal combustion engine is not controlled by the generator, the execution of rich spike control of temporarily enriching the exhaust air-fuel ratio to reduce NOx held to the NOx storage reduction catalyst is forbidden. Alternatively, in the case of performing rich spike control in the idling operation of the internal combustion engine, throttle opening is reduced before performing rich spike control.

    Abstract: PROBLEM TO BE SOLVED: To efficiently operate an internal combustion engine in a hybrid vehicle.
    SOLUTION: In a hybrid system 10 a torque calculating part 100b calculates torque of an engine 200 from torque reaction of a motor generator MG1. A fuel consumption rate calculating part 100c calculates an instantaneous fuel consumption rate in the engine 200 on the basis of such the calculated engine torque, a fuel injection quantity and an engine speed.

    Abstract: PROBLEM TO BE SOLVED: To effectively operate an internal combustion engine in a hybrid vehicle even in a range where the efficiency in a hybrid vehicle is locally low. SOLUTION: In a hybrid system 10, a torque calculation part 100b calculates torque of an engine 200 from torque reaction force of a motor generator MG1. A fuel consumption rate calculation part 100c calculates an instantaneous fuel consumption rate in the engine 200 on the basis of a fuel injection amount and engine rotational speed. A working line updating part 100d updates a working line by executing a working point learning process on the basis of the calculated fuel consumption rate. When the engine 200 has the locally low efficiency range on the working line, a working point setting part 100f sets therein as a working point either having higher efficiency of a working point corresponding to required output or two working points switched and controlled to maintain the required output.
