摘要： PROBLEM TO BE SOLVED: To ensure stable low temperature combustion by switching first combustion having rate of inert gas in a combustion chamber much more than a rate of inert gas where a soot generating rate becomes a peak level, and second combustion having few inert gas rate, and moving a first operating region to a high load side toward reducing an air-fuel ratio. SOLUTION: In a diesel engine 1 wherein EGR gas is re-circulated to an intake passage 17, a soot generating rate is gradually increased in the case where a rate of inert gas in a combustion chamber 5 is increased, a fuel and gas temperatures at the time of combustion are reduced lower than a soot generating temperature, and soot is hardly generated. First combustion wherein there is a rate of inert gas in the combustion chamber much more than a rate of inert gas where a soot generating rate becomes a peak level and the soot is hardly generated, and second combustion having few inert gas rate are freely switched. An operating region is divided into a first operating region of a low load side where first and second combustion are carried out, and a second operating region of a high load side, and the first operating region is moved to the high load side toward reducing an air-fuel ratio.

摘要： PROBLEM TO BE SOLVED: To immediately approach an air-fuel ratio a target air-fuel ratio when a first combustion and a second combustion are changed over. SOLUTION: A first combustion that an exhaust gas recirculation(EGR) gas amount in the inside of a combustion chamber 5 is larger than an EGR gas amount that a generation amount of soot is peaked and soot is hardly generated, and a second combustion that the EGR gas amount in the inside of the combustion chamber 5 is smaller than the EGR gas amount that the generation amount of soot is peaked, are selectively performed. When changing over from the first combustion to the second combustion, the opening of a throttle valve 20 is temporarily made larger than a target opening, and after that, the opening is returned to the target opening.

摘要： PROBLEM TO BE SOLVED: To extremely decrease a generation amount of soot and NOX during low load operation of an engine. SOLUTION: First combustion wherein a recirculation exhaust gas amount fed in a combustion chamber is higher than a recirculation exhaust gas amount available when a generating amount of smooth is increased to a peak and second combustion wherein a recirculation exhaust gas amount fed in a combustion chamber is lower than a recirculation gas amount is lower than a recirculation gas amount available when a generating amount of sooth is increased to a peak are selectively switched. When first combustion is switched to second combustion or the second combustion is switched to the first combustion, an exhaust gas recirculation factor is changed in a step-form manner.

摘要： PROBLEM TO BE SOLVED: To materialize the sure fixing at mounting and improve the work efficiency at removal, concerning a mounter for a wire harness for locking a wire harness capable of mounting and removal. SOLUTION: This mounter is provided with a mounting member 3 attached to a wire harness 2, and a holder member 4 possessing the first regulating part (plate spring 8 and a lock plate 14) for regulating the vertical dislocation of the mounting member 3 in mounting condition and the second regulating part (a locking step 10 and a side face 17) for regulating the parallel motion of the mounting member 3 in mounting condition. And, out of the first and second regulating parts, at least one side is constituted to be elastically shiftable, and also this is constituted such that one regulating part shifts by the drawing- apart force in the case of having moved the wire harness 2 in the drawing-apart direction to the mounting face, and that the regulation to the mounting member 3 by the other regulating part is released.

摘要： PURPOSE: To provide a vehicle operation device which can be adjusted to an operation force matching a driver. CONSTITUTION: The operation lever 20 of the vehicle operation device 12 is made rotatable in the front-rear direction of a vehicle around a shaft part 18 to make possible braking operation by rotating the operation lever 20 forward and acceleration operation by rotating the operation lever 20 backward. The operation lever 20 is provided with a pin 42, which presses the piston 26 of an operation force adjusting cylinder 22 in a cylinder body 24. The operation force to the stroke of the piston 26 of the operation force adjusting cylinder 22 is adjustable, and consequently the front-rear directional operation force of the operation lever 20 can be adjusted to an operation force matching the driver.
