An intake throttle valve is located in an intake passage upstream of first and second intake ports, such that intake air flows into mainly the first intake port to generate a swirl flow when an opening degree of the intake throttle valve is not larger than a predetermined value, and flows into both the first and second intake ports when the opening degree thereof is larger than the predetermined value. Furthermore, first and second fuel injection valves for respectively injecting fuel to the first and second intake ports are controlled to inject fuel from the first fuel injection valve when the opening degree of the intake throttle valve is not larger than about the predetermined value, and to inject fuel from both the first fuel injection valve and the second fuel injection valve when the opening degree of the intake throttle valve is larger than about the predetermined value.

The invention relates to the technical field of continuous wall constructions and discloses a device for utilizing dead load of concrete to eliminate a gap of a continuous wall. The device comprises asupporting frame. Evenly mixing plates are movably connected into the supporting frame. The bottoms of the evenly mixing plates are movably connected with rotating shafts. The bottoms of the rotatingshafts are movably connected with fixing pieces. The surfaces of the rotating shafts are movably connected with homogenizing plates. The inner portions of the homogenizing plates are movably connected with gears. The inner portions of the gears are movably connected with scroll springs. The surfaces of the scroll springs are movably connected with winding rollers. Accumulation at the position ofthe evenly mixing plates facilitates homogenization of the concrete in a later period; and concrete flowing out from the surfaces of the evenly mixing plates can flow to the surfaces of the homogenizing plates, so that the rotation speed of the gears on the surfaces of the rotating shafts becomes rapider. Due to the action of the scroll springs and the multiple homogenizing plates, the flowing concrete is accumulated firstly and then flows down from the surfaces of the homogenizing plates, each accumulation gives a certain speed to the concrete, and then the effect of utilizing the weight of the concrete to feed the concrete layer by layer so as to eliminate the gap is achieved.

The invention discloses a gas medium homogenization device for high-power laser diode sintering, which relates to the field of optoelectronic technology. The suction nozzles of the equipment are sealed and matched, and the support is provided with an intake passage and an exhaust passage that communicate with the intake pipe and the exhaust pipe, and the other ends of the intake passage and the exhaust passage communicate with the hollow area in the middle of the support. Install the bracket on the sintering table, so that the heat sink with solder is fixed to the connecting plate in the hollow area, a high-power laser diode is placed on the heat sink with solder, and the suction nozzle of the sintering equipment is adsorbed above the hollow area, reducing the gas Entering from the intake passage, it can fully cover the surface of the solder, which can fully restore the solder in the sintering area of ​​the laser diode chip, and then use the exhaust passage to export the reduced exhaust gas to form a complete circuit. The invention has the advantages of simple structure, homogenization of reducing gas, and improvement of consistency of solder reduction.

The invention relates to the technical field of continuous wall construction, and discloses a device for eliminating gaps in the continuous wall by using the self-weight of concrete, including a support frame, a mixing plate is movably connected inside the support frame, and a rotating shaft is movably connected to the bottom of the mixing plate. The bottom of the rotating shaft is movably connected with a fixed part, the surface of the rotating shaft is movably connected with a homogenizing plate, the inside of the homogenizing plate is movably connected with a gear, the inside of the gear is movably connected with a scroll spring, and the surface of the scroll spring is movably connected with a wired roller . Accumulation here is beneficial to the homogenization of concrete in the later stage; the concrete flowing out from the surface of the mixing plate will flow to the surface of the homogenizing plate, so the rotation speed of the gear on the surface of the rotating shaft becomes faster, due to the action of the vortex spring, and the homogenizing plate The number of concrete is multiple, so the flowing concrete will accumulate first and then flow down the surface of the homogenizing plate, and each accumulation will give the concrete a certain speed, so as to achieve the effect of using the concrete weight to pass into the concrete layer by layer to eliminate the void.
