摘要： PURPOSE: To preliminarily prevent the speed change shock by providing a speed increasing request judging means to judge the degree of the speed increasing request and an up-shift limiting means to limit the up-shift associated with the release of the deceleration control according to the judged degree of the speed increasing request. CONSTITUTION: When an accelerator pedal is returned and the deceleration is requested while a vehicle is running with its prescribed speed change shift, the deceleration is controlled to indicate the down-shift from the speed change shift. When the accelerator pedal is stepped in to request the speed increase while the deceleration is controlled, a speed increasing request judging means 1 judges the degree of the speed increasing request. An up-shift limiting means 2 limits the up-shift associated with the release of the deceleration control according to the degree of the speed increase request. For example, when the judged degree of the speed increasing request is large to some extent, the up- shift associated with the release of the deceleration control is prohibited. As a result, no up-shift is generated during the torque change associated with the speed increasing request, and the shock can be preliminarily prevented.

摘要： PROBLEM TO BE SOLVED: To improve cleanliness of exhaust gas and fuel consumption performance by making gaseous fuel collide against intake air flow, and evenly mixing air with the gas fuel. SOLUTION: In this mounting method for an injection valve of a natural gas engine, an injection valve 6 is arranged on a side wall of an intake pipe 27 in a downstream of a throttle valve 25. An injection port of the injection valve 6 is directed opposedly to intake air for injecting natural gas fuel only in the intake stroke. The injection valve 6 is arranged on the outer side of a bent portion of the intake pipe 27, and also in the downstream thereof. The natural gas fuel is injected to an area where velocity of the outer intake air is relatively higher compared to the center axis of the bent portion.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of malfunction such as rough idle by stabilizing a combustion condition for a period leading from just after starting to a steady condition. SOLUTION: An electronic control unit(ECU) 41 executes the open loop control of the solenoid 11a of an idle speed control valve (ISCV) 11 as intake air quantity adjusting means until a cooling water temperature reaches a predetermined degree after an engine 1 is started. After the cooling water temperature is reached the predetermined temperature, the ECU 41 continues the open loop control for delay time, and executes normal feedback control after lapse of the delay time. The delay time is set more longer the more the intake temperature is lower. Therefore, the delay time, that is, convergent time until the opening of the ISCV 11 reaches a target opening is lengthened in case that the temperature of the combustion chamber 1a of the engine 1 is yet lower although the cooling water temperature has reached the predetermined temperature. Therefore, at a point of time when the temperature of the combustion chamber 1a of the engine 1 is sufficiently raised, the real opening of the ISCV 11 is lowered to the target opening.

摘要： PURPOSE: To prevent recurrence of malfunction resulting from speed dropping while a vehicle is decelerating. CONSTITUTION: An electronic control unit(ECU) 41 duty-controls the solenoid 11a of an ISCV (Idle Speed Control Valve) 11 based on a learning value when an engine 1 is in an idle condition. While a vehicle is being driven with the engine 1 not in an idle condition, but in excess of a fixed speed, the solenoid 11a is subject to open loop control, when the target opening of ISCV11 is increased to an opening obtained by adding the correcting value to the learning value. While the vehicle is running above the fixed speed, the opening of the ISCV11 is always increased and controlled. It is thus possible to prevent engine speed from dropping largely even if the vehicle becomes in a decelerating condition during running.

摘要： PURPOSE: To improve acceleration ability and fuel consumption by a method wherein the engaging and disengaging state of a lockup clutch is detected and a shift is controlled by employing a map which is differed with a time during release of a lockup clutch and a time during engagement of a lockup clutch. CONSTITUTION: An automatic transmission comprises a torque converter 1 with a lockup clutch 7; a three-shift part being a main shift part; and an overdrive 3 being an auxiliary shift part. A given shift speed is established in such a way that an oil pressure fed from an oil pressure control device 10 is controlled by a solenoid valve. In the shift control, two kinds of maps responding to the engaging and disengaging state of the lockup clutch 7 are provided as a control map. During release of the lockup clutch, a first map having a shift up line and a down shift line set to the higher throttle opening side than the shift up line is employed. During lockup clutch engagement, the second map set to the relatively lower throttle opening side is employed to effect shift control.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration in exhaust emissions by quickly controlling the air-fuel ratio to a stoichiometric one in switching between a main fuel supply amount correction air-fuel ratio control and auxiliary fuel supply amount correction air-fuel ratio control.
SOLUTION: An LPG engine 1 comprises: a main fuel control valve 42 and an injector 11; an oxygen sensor 55 detecting the air-fuel ratio; and an electronic control unit (ECU) 4 correcting a main fuel supply amount by a main fuel control valve 42 based on a detected air-fuel ratio, corresponding to an operational status or correcting the auxiliary fuel supply amount by the injector 11 based on the detected air-fuel ratio. In switching between the air-fuel ratio control by the main fuel supply amount correction and an air-fuel ratio control by the auxiliary fuel supply amount correction, the ECU 4 converts a correction amount after the switching based on a predetermined supply ratio, so that the main fuel supply amount correction amounts and the auxiliary fuel supply amount correction amounts before and after the switching become the same, and controls the main fuel supply amount correction amount or the auxiliary fuel supply amount correction amount during the switching to be at a predetermined rate of the correction amount before the switching.

摘要： PURPOSE: To prevent the sudden drop of rotating speed by a load even when the load is added at idling, thereby avoiding a trouble by the drop. CONSTITUTION: An electronic control unit(ECU) 41 open-loop controls the opening of an ISCV(idle speed control valve) 11 when an engine 1 is in idling state, particularly, when the shift position is changed from N-range to D-range. The value in which a prescribed value is added to the duty ratio up to that time is first set as a D-range duty ratio. Thereafter, the D-range duty ratio is gradually damped by the damping ratio portion. At that time, the rotating speed change ratio is calculated, and the damping ratio is set on the basis of it. Namely, when the decreasing degree of rotating speed is high, the damping ratio is set to a small value. Therefore, even when the adding degree of load is slightly differed according to individual engines 1, the intake air quantity can be regulated in conformation to the load.
