When the engine is operating in a medium/low load range, when the piston is located near compression top dead center, the injection nozzle
The required amount of fuel is supplied in the form of a liquid column with strong penetrating force toward the wall of the front combustion chamber. Part of the supplied fuel evaporates on the high-temperature wall of the combustion chamber to form a lean air-fuel mixture within the combustion volume, and the rest of the fuel evaporates along the wall of the combustion chamber toward the spark plug. It concentrates in the vicinity and forms a rich mixture with good ignitability. As a result, slow stratified combustion can be achieved within the front eight self-combustion chambers.

When the engine is in a high load range, in order to obtain high output, it is necessary to spread the combustion in the combustion chamber into the cylinder, and in addition to supplying fuel into the combustion chamber as in the case of medium and low load ranges. Before that, when the piston is in a position from the intake stroke to the first half of the compression stroke, fuel is supplied into the cylinder with a weak penetration force so that the fuel can be easily atomized from the injection nozzle.

In this case, the fuel is atomized using the swirl formed within the cylinder during the intake stroke, forming a thin air-fuel mixture within the cylinder.

As mentioned above, the fuel supply into the combustion chamber in the medium/low load range and high load range must be directed toward the concave wall of the combustion chamber on the top surface of the piston when the piston is near compression top dead center. Therefore, the injection nozzle is oriented at a shallow angle with respect to the top surface of the piston.

For this reason, when supplying fuel into the cylinder in a high load range, the injected fuel is directed toward the cylinder wall.
Further, there is not much distance between the injection port of the injection nozzle and the cylinder wall surface.

In the above-mentioned high load range, when fuel is supplied into the cylinder, the fuel is injected in a state where it is easily atomized, so a small amount of fuel is atomized by swirl before reaching the cylinder wall surface. When the amount of fuel supplied into the cylinder increases, unatomized liquid fuel comes into contact with the cylinder wall.

As a result, not only does the atomization and mixing of the fuel deteriorate, but the lubricating oil on the cylinder wall is washed away by the fuel, increasing the friction between the piston and cylinder, increasing the amount of lubricating oil consumed, and further increasing the amount of lubricating oil consumed. fuel gets mixed in and causes dilution.
