摘要： PURPOSE:To obtain a good air-fuel-mixed state over a wide operation range in an independent, cylinder-to-cylinder injection system, in which fuel is injected in a synchronized manner with a suction stroke, by sending the injected fuel onto a combustion chamber side, taking advantage of an air flow-velocity at which no wall surface slagging is formed. CONSTITUTION:In controlling a fuel injection valve 7, which is arranged at a suction port, based on output signals from an engine speed sensor 8, a crank angle sensor 9, a cooling water temperature sensor 10, and an inlet sensor 11, a range of the air flow velocity, that is lower than a critical air flow velocity Vpc, in which no wall surface slagging takes place to an inlet pipe of an injected fuel passage, is obtained first from sine-wave-resembled air flow velocity characteristics in the vicinity of the inlet valve in the range from valve-opening to valve-closing of the inlet valve in each cylinder. Next, a valve-opening position of a fuel injection valve 7 is decided, based on an air feeding valve opening position corresponding to the air flow velocity lower than Vpc. When the range of the air flow velocity lower than Vpc varies because of a change in the engine speed, the starting time of the valve opening of the fuel injection valve 7 is varied, according to the variation of the range.

摘要： PURPOSE:To simplify a fuel injection valve in structure and reduce its cost as well as improve on responsiveness at transition duration by attaching an adapter, with two nozzles, to a tip part of the pintle type fuel injection valve and locking it through a space between. CONSTITUTION:An adapter 10 with two nozzles 14 is attached to a tip part 8 of a pintle type fuel injection valve 3 and clamped through a spacer 9 between. When a driving pulse is inputted into this fuel injection valve 3, a pintle 11 is lifted up, the seat part 16 opens, and fuel in a fuel sump 17 flows out along the pintle 11 as being metered by an orifice 18. Thus, a structure is simplified, and cost becomes very inexpensive. In addition, responsiveness at transition duration is yet more improvable.

摘要： PURPOSE:To obtain stable starting performance by setting the quantity of reference starting injection fuel allocated to the injector of a throttle valve part to a higher value when the temperature is lower. CONSTITUTION:Injectors 20 and 31 are located at an intake port part 6 and a throttle valve part 2, respectively. A means 34 calculates the reference starting injection quantity TST as the necessary quantity of fuel and a means 35 sets the rate KDISST of the reference starting injection quantity allocated to the injector 31 of the throttle valve part to be higher when the temperature is lower. According to this allocation rate KDISST quantities Tit and Tip of fuel injected from a pair of the injectors 31 and 20 are calculated by a calculating means 36 and 37, respectively and outputted by the means 38 and 29 to related injectors 31 and 20. So when fuel of almost necessary quantity is ejected from the injector 31 of the throttle valve part is ejected with the engine at a low temperature, injected fuel is made finer with the air of air stream flowing around the throttle valve 2 and atomized in an intake manifold 3 to form premixture quickly.

摘要： PURPOSE:To improve a mixing characteristic of air-fuel mixture as well as to aim at the promotion of lean combustion and reduction in fuel consumption by making a partial cylinder fuel injection valve and premixed fuel injection valve take partial charge of a fuel quantity corresponding to a request air-fuel ratio for partial load driving or the like on the basis of a setting ratio. CONSTITUTION:A premixed fuel injection valve 12 is used in combination with a partial cylinder fuel injection valve 11 at a time when it is at least in a partial load driving area of an engine, whereby a fuel quantity corresponding to a request air-fuel ratio of the engine is alloted and sprayed on the basis of the setting ratio of both these valves. At this time, each fuel injection timing of these valves 11, 12 provides a phase difference in consideration of flow delay time of fuel. With this constitution, the premixed fuel injection valve 12 sprays the fuel quantity allotted at a setup position of the partial cylinder fuel injection valve 11 and an intake passage 16 at the more upstream than an intake manifold 15. This fuel is premixed with air in the intake passage 16 before reaching to an intake port of the engine, and it is distributed to each cylinder 13 of the engine together with a fuel spray out of the partial cylinder fuel injection valve 11 on an air flow in the intake passage.

摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine excelling in combustion stability.
SOLUTION: The internal combustion engine has a first variable valve train capable of continuously varying a first lift characteristic among lift characteristics of an intake valve and a second variable valve train capable of continuously varying a second lift characteristic different from the first lift characteristic. When load required for the internal combustion engine is in reducing transition and a target value (D4) of the first lift characteristic is larger than a first lift characteristic maximum load attainment valve (D3) at which load attainable at a present value (B4) of the second lift characteristic and a present engine rotation speed is the maximum, the target value (D4) of the first lift characteristic is shifted to a position which is equal to or smaller than the first lift characteristic maximum load attainment valve (D3) and in which required load is attained at the present value (B4) of the second lift characteristic and the present engine rotation speed. The target value (D4) of the first lift characteristic can be prevented from becoming too large and causing deterioration of the combustion stability.

摘要： PROBLEM TO BE SOLVED: To avoid a problem wherein, when an engine is stopped through an idle state, a lift/operating angle of an intake valve remains small and a necessary amount of intake air for a next start is not secured. SOLUTION: It is judged that the internal combustion engine is in a state before stop when a shift lever position of an automatic transmission is in a P-range position. When a P-range switch swP is tuned on at time T after stop of a vehicle, a target opening of a throttle valve is changed from a throttle valve target opening B1 in normal time to a throttle valve target opening B2 before stop and suction vacuum gets behind variation of the throttle valve opening and varies as C1. A target angle of a first variable valve operating mechanism for controlling the lift/operating angle of the intake valve is fixed at a predetermined value D1 for start. When a key is tuned off in this state and the engine is stopped, the first variable valve operating mechanism stops while being in a position suited for the next start, and when the next start, the intake air amount minimum required for the start is secured immediately after start of cranking.

摘要： PROBLEM TO BE SOLVED: To prevent uncomfortable feeling of a driver by suppressing the fluctuation of driving force in a vehicle due to excessive power even when the excessive power is generated. SOLUTION: When a gear is shifted to a low gear ratio in a transmission 13, a controller 1 allows a first motor generator 11 to be operated for power generation so as to reduce the rotation speed of an engine 10 and allows a second motor generator 12 to be operated for power running with the use of the generated power. In this case, the controller 1 determines the generation of the excessive power by comparing the generated power of the first motor generator 11 with the requested power of the second motor generator 12. When it is determined that the excessive power is to be generated, efficiency is reduced in at least one of the first and second motor generators 11, 12. COPYRIGHT: (C)2007,JPO&INPIT
