子となつていたのである。 Conventionally, an atomization means is placed inside the combustion chamber, and the fuel particles are initially diffused with a bright flame, and then the following fuel particles are immediately vaporized at high speed by the heat of combustion, promoting diffusion mixing and blowing out air in a partially premixed state. In a combustion device that performs flame-holding combustion in the hole, the overall or local mixture ratio in the premixed state, the jetting speed of air at the flame-holding hole, and the jetting condition directly affect the combustion state. However, because air was simply blown from the blower mechanism to the middle cylinder, instantaneous fluctuations and pulsating flow of the blown air caused unstable flame-holding, resulting in unburned matter being discharged and combustion noise. This was a contributing factor. In other words, the instantaneous fluctuations and pulsating flow of the blown air cause fluctuations in the jetting speed and jetting condition from each air jetting hole, resulting in changes in the mixture ratio between the middle cylinder and the auxiliary combustion cylinder (including local mixture ratios). ), changes in the balance position with the combustion speed of the flame may cause the combustion reaction to be incomplete, generating or emitting unburned substances (carbon monoxide, HC, aldehydes, etc.) and becoming a factor in combustion noise. It was.

方向に偏心させて設けたものである。 In order to achieve the above object, the present invention divides and adjusts the amount of air ejected into upper and lower parts inside the middle cylinder, and provides a divided cylinder that communicates with the upper part on the inside and the lower part on the outside, on the central axis of the middle cylinder. On the other hand, it is provided eccentrically in the direction away from the atomization means.

きる。 With the above configuration, instantaneous fluctuations or pulsations in the air volume and pressure of the air supplied from the air blowing mechanism are smoothed out, and the amount of ejection in each region of the premixing region and combustion region is also adjusted. The mixing ratio is kept stable and within a certain range. This results in the formation of a stable flame. Furthermore, because of the eccentricity, the amount of air ejected from the side where the fuel flies is large, so the amount of fuel that collides with the surface of the middle cylinder is also reduced. As a result, it is also possible to suppress layering due to the tar formation of the collisionally deposited fuel.

量が激減することによつて極力抑制される。 In the above configuration, first, when the motor 17 is energized and the blower mechanism is activated, combustion air is supplied to the middle cylinder 10 through the wind cylinder 20. is further smoothed by the rectifying grid 16 which serves as a resistor. Further, due to the inflow resistance and the limitation of the inflow amount by the inlet of the divided cylinder 15, the inflow amount is adjusted up and down the middle cylinder 10, and the eccentricity of the divided cylinder 15 causes the air to flow toward the spiral injection valve 3 below the middle cylinder 10. is supplied and ejected in larger amount than on the opposite side. Then, air is ejected from each air ejection hole 14 of the middle cylinder 10 to the premixing region b in the combustion chamber 6 and then to the combustion region a at a constant ratio. Further, after a certain time delay in the operation of the air blowing mechanism, the ignition device 4 is energized to generate a spark. Thereafter, liquid fuel pressurized by the operation of the fuel pump 2 is sprayed into the combustion chamber 6 from the spiral injection valve 3. Air of a certain amount or less (air excess ratio m<0.4) relative to the amount of fuel sprayed is ejected from the air injection hole 14 at the bottom of the middle cylinder 10 into the premixing region b, and is forced to mix with the fuel particles. ignition occurs after a certain mixing ratio is reached. At this time, collision of combustion particles onto the surface of the middle cylinder 10 is suppressed as much as possible due to the jet speed of a large amount of air jetted out from the air jet hole 14 in the lower part of the middle cylinder 10 on the side of the spiral injection valve 3 . The flame forms a swirling flame with high brightness due to diffusion combustion around the middle cylinder 10,
Move to the upper part of the combustion chamber 6. In addition, some of the flames stagnate at the bottom 9 of the combustion chamber 6, and new air is introduced into the fuel mass where the evaporation and vaporization of the fuel is further promoted by the radiant heat of the flame or the heat of the recirculated combustion gas. Combustion is performed while supplying. After this, the concentration of the premixture increases and moves to the upper part of the middle cylinder 10 without being combusted. Therefore, the bright flame immediately moves to the air nozzle 14 above the middle cylinder 10, takes in air from the nozzle 14, and changes into a non-bright flame while forming a single-hole flame. Thereafter, as the temperature inside the combustion chamber 6 rises, the rate of evaporation, vaporization, and mixing of the fuel particles in the air is rapidly accelerated, and the re-liquefied portion due to the collision of the fuel particles is also subjected to heat transfer in the liquefaction section. evaporate and
By promoting vaporization, a stable vaporized fuel concentration can be obtained. Further, a stable flame is formed by the rectified and divided air, that is, the air in a stable jetting speed and jetting state from each jetting hole 14. Furthermore, the accumulation of tar on the surface of the inner cylinder due to repetition of the above operation is also suppressed as much as possible by drastically reducing the amount of colliding fuel particles.
