摘要： PROBLEM TO BE SOLVED: To provide a fuel injection timing control method for a multicylinder internal combustion engine, allowing quick start of the engine. SOLUTION: At a calculation timing θc in each cylinder, a fuel injection parameter such as an injection timing or an injection amount is calculated. Cylinder pressure Ps at starting cranking and cylinder pressure Pd at a detection timing right after starting cranking are detected for each of the cylinders. In accordance with a change amount of each cylinder pressure, a cylinder is specified which has the earliest fuel injection timing after the detection timing, and a cranking angle θd at the detection timing is determined. When the cranking angle θd at the detection timing exists before the calculation timing θc (a solid line) in view from an intake bottom dead center, fuel injection is performed in order from the specified cylinder. When the cranking angle θd at the detection timing exists after the calculation timing θc (a broken line), fuel injection is performed in order from a cylinder which has a fuel injection timing next to the specified cylinder.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of preventing purifying of exhaust gas from becoming insufficient due to lowering of temperature of an exhaust emission control device including a catalyst after the engine is restarted, in the case of the engine being temporarily stopped by economic running control or hybrid control. SOLUTION: In this internal combustion engine, when the amount of inactive gas inside a combustion chamber is increased, the generated amount of soot increases and reaches its peak. The exhaust emission control device including the catalyst having an oxidation function is positioned in the engine exhaust passage. Before the engine is temporarily stopped, an operating mode is performed wherein the generated amount of substances, which causes an exothermic reaction in the exhaust emission control device, increases. The substances generating exothermic reaction are unburned HC and CO. In the operating mode, control is performed so that the amount of inert gas inside the combustion chamber is more than the amount of inert gas wherein the generation amount of soot is at its peak. Before the engine is temporarily stopped, the operating mode is performed at least during a set time. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a control method in starting an engine of a diesel hybrid vehicle for suppressing the generation of white smoke in starting the engine. SOLUTION: Combustion pressure waveform is monitored in starting the diesel engine 11, and a combustion rate to a fuel injection quantity is computed from the combustion pressure waveform. When the combustion rate is a preset reference value or less, the diesel engine 11 is stopped, and a changeover to EV travel by the motor generator 17 is made to suppress the generation of white smoke. When the charged state of a battery 20 becomes a preset lower limit value or less after the EV travel, the diesel engine 11 is restarted to carry out high load side operation, and the battery 20 is charged.

摘要： PROBLEM TO BE SOLVED: To provide a technology for preventing creep torque from being set low by the stop of an engine in a stop and start control system of an internal combustion engine. SOLUTION: This stop and start control system of the internal combustion engine comprises a transmission allowing automatic clutch operation in gear shifting and an automatic stop/start means automatically stopping and starting the internal combustion engine. The control system also comprises a transmission control means for changing the creep torque while performing the clutch operation of the transmission. The transmission control means lowers the creep torque when an engine rotational speed is lowered to a specified rotational speed or lower, and based on the lowered amount of the creep torque, changes the set conditions for the creep torque and does not changes the set conditions when the engine is stopped and started by the automatic stop/start means.

摘要： PROBLEM TO BE SOLVED: To provide a controller for a power source for a hybrid vehicle which can bring actual torque close to the feeling of torque production that the driver originally requests. SOLUTION: The assisting torque of a motor which is generated according to the difference between the torque requested by the driver and the real torque of an internal combustion engine decreases because the limitation processing is performed at decision of the driver-requested torque itself, when the torque transmitted to the axle changes suddenly at the speed change of the internal combustion engine or at the start of the vehicle or the like. Here, the motor-assisting torque is increased by relaxing the above limitation, whereby this controller can bring the actual torque close to the torque generation feeling that the driver originally requests.

摘要： PROBLEM TO BE SOLVED: To transmit torque of a rotary device to wheels and control reduction of a speed change response property when performing speed change. SOLUTION: A controller for a power train for vehicles is provided with a power transmitting member, speed change gears mounted on the power transmitting member and capable of relatively rotating together with the power transmitting member, a synchronizing mechanism synchronizing the rotation speed between the speed change gears and the power transmitting member and performing speed change so that the power transmitting member and the speed change gears are connected with each other to rotate together, and a rotation device connected with the speed change gears in a power-transmittable state. In the controller, a synchronization control means (step S1 or step S3) controlling increase of time necessary for synchronization between the speed change gears and a power transmitting shaft during the speed change is arranged by differentiating first output control of the rotation device when performing the speed change and second output control of the rotation device when not performing the speed change.
