。(Prior art) This application was filed by making the central axes of the front and rear chambers of the pre-combustion chamber eccentric to opposite sides with respect to the central axis of the fuel injector, and creating a jet impingement surface between the front and rear chambers. We have already proposed a pre-combustion chamber for a diesel engine that has a stepped section.
0898). Due to its structure, starting is easier, but the combustion noise immediately after starting is a little louder.Also, since the vortex velocity is reduced by the jet impingement surface, it is easy for carbon to build up at the tip of the fuel injector. The angle of the spray changes, and the noise tends to increase during low idle and cold conditions.On the other hand, in order to increase the vortex velocity, the vortex combustion chamber is shaped like an elongated sphere, an egg, or a smooth shape approximating this to the cylinder center aKG. In addition to improving the cross-sectional shape of the nozzle, the nozzle is made up of a main round hole and a pair of connecting paths that extend laterally and are connected to this round hole. It has already been proposed that the main combustion chamber side is large and the vortex combustion chamber side is small, so that the connecting path becomes fan-shaped and widens toward the main combustion chamber side (Japanese Patent Publication No. 57-59410 )

In order to merge, a cavity phenomenon occurs on both the left and right sides of the main jet, and in the cavity part of the main jet, of course,
The auxiliary jet flow that has flowed into the swirl combustion chamber via the side channel is also difficult to reach, resulting in insufficient mixing of the air and the smell from the fuel injection valve. In this way, complete air-fuel mixture formation is not achieved in the swirl combustion chamber, and therefore the combustion performance tends to deteriorate.

The aim is to improve the turbulence combustion chamber so that complete mixture formation can be achieved within the vortex combustion chamber.

なる。極低温時はグロープラグｌＯを使用する。The air jet flowing from the main combustion chamber 7 to the vortex combustion chamber l via the nozzle 6 is caused by the shape of one side of the nozzle 6 being round holes 6a as shown in FIG.
The combustion chamber l is formed by the groove-like slit portion 6b.
As shown in FIG. 3, the velocity distribution within the jet is strong in the central portion of the main jet supplied from the round hole 6a, and gentle in both side portions of the secondary jet supplied from the slit portion 6b. As a result, there is no cavity where the air is thin on both sides of the main air jet (the front side and the back side in FIG. 1). That is, the slit portion 6b
The cavities on both sides of the main jet are eliminated by the secondary jets supplied from the main jet. For this reason, the air-fuel mixture is quickly formed within the swirl combustion chamber l. Also, when the combustion gas in the swirl combustion chamber 1 flows into the main combustion chamber 7, the slits 6b on both sides of the round hole 6a create a sub-combustion gas flow beside the main combustion waste flow, and the flow of combustion gas in the main combustion chamber 7 A combustion gas flow is formed in which the flow velocity is high toward the center and becomes slower toward the outside, and the main combustion chamber 7
The combustion air inside is fully utilized. The fuel injection valve 5 is mounted in an inclined position such that the angle θ is 20 to 25° with respect to the center line 02-Ox of the swirl combustion chamber, and injection is directed toward the center of the swirl combustion chamber l. With such a structure, the spray is not easily discharged into the main combustion chamber 7 at the time of starting, and the ignition at the time of starting the engine 11 is improved. Use a glow plug IO at extremely low temperatures.

改善される；低温始動時の騒音もよくなる。(Effects of the Invention) According to the present invention, since the cross section of the combustion chamber nozzle 6 has a special shape, the thin flow into the vortex combustion chamber 1 is strong in the center and gentle on both sides, and the mixture is formed quickly. It will be held on. When the combustion gas in the swirl combustion chamber 1 flows into the main combustion chamber 7, secondary combustion gas flows are generated on both sides of the main combustion gas flow from the slits 6bK on both sides, and the distribution of the combustion gas flow is faster in the center. A gentle gas flow is formed on the outside of the main combustion chamber 7.
The combustion air inside the engine can be fully utilized, improving combustion performance; noise during cold starting is also improved.
