煙を発生し易くなる。更に、エンジンが新しいう
ちは黒煙は余り出ないが、古くなると出易くな
る。これはエンジンにおける圧縮圧力が低下する
ことによるものと考えられる。 In cars equipped with diesel engines, almost no black smoke is emitted when the car is running at a constant speed, and there is also little black smoke when the air-fuel ratio is relatively low. On the other hand, during startup, the temperature of the combustion flame is lowered by the particles of the fuel spray and the walls of the combustion chamber, which prevents complete combustion and tends to generate soot and smoke. Furthermore, during rapid acceleration, the temperature rise in the combustion chamber does not accompany the sudden increase in fuel, resulting in incomplete combustion, which tends to generate black smoke. Furthermore, when the engine is new, it doesn't emit much black smoke, but as it gets older it becomes more likely to emit black smoke. This is thought to be due to a decrease in compression pressure in the engine.

なうようにする。 This invention takes out a portion of the engine oil from the engine's oil pressure switch mounting hole, and controls the amount of oil in an oil amount control box that is operated in conjunction with the control arm of the injection pump that is operated by the accelerator. 1 is a black smoke prevention device for a diesel engine characterized by injecting it from an injection nozzle disposed in a manifold and inhaling it into a cylinder together with intake air, and the drawings show an embodiment thereof. In the figure, 1 is a diesel engine, 2 is a cylinder head, 3 is a manifold, and 4 is an air cleaner. 5 is a hydraulic switch, and an oil extraction pipe 6 is installed in its mounting hole.
Allocate. 7 is a mounting bolt for the oil extraction pipe 6. The oil extraction pipe 6 extends to the manifold 3, and an oil injection nozzle 8 is provided at its tip.
facing inside manifold 3. Reference numeral 9 denotes an oil quantity control box, through which the oil extraction pipe 6 is passed to adjust the oil quantity. The oil amount control box 9 adjusts the oil amount in conjunction with the movement of a control arm 12 of the injection pump 11, which is operated according to the degree of depression of the accelerator pedal 10.

る。 To explain an embodiment illustrating the operation of the present invention, when the accelerator pedal 10 is depressed, the oil amount control box 9 is actuated via the control arm 12 of the injection pump 11, and the amount of engine oil is adjusted according to the degree of depression. part into the oil take-out pipe 6. The oil is then injected from the oil injection nozzle 8 due to the negative pressure within the manifold 3. The oil is warmed by the heat of the engine, so when it is injected, the air it comes into contact with is warmed, so air that has been warmed to some extent is drawn into the combustion chamber.
As a result, the temperature rise in the combustion chamber does not cause incomplete combustion without a sudden increase in fuel, and black smoke is no longer generated. In addition, this injected oil improves the adhesion between the valve and the valve seat, and prevents oil film from adhering to the cylinder inner wall, piston, piston ring, etc., which reduces compression pressure and prevents their wear. It will also be done.
