摘要： PURPOSE:To obtain optimum combustion condition of an engine by providing a blade angle adjusting unit on a supercharger, setting a desired combustion index, setting scavenging pressure with the set value at a rack position, setting a blade angle of a supercharger turbine by the scavenging pressure and an engine output and by correcting the blade angle properly. CONSTITUTION:Rotating number 11 of an engine 1, rack graduation 12, scaveng ing pressure 13 are detected by detectors 6, 5, 4 and a variable turbine blade senses a blade angle of a supercharger (VG supercharger). And these are converted to digital amount by A/D converters 101-105 and output L is calcu lated by an output calculator 110 by rotating number and the rack graduation. A combustion index is set by a setting unit 107 by instruction of a combustion control handle 3, and a set value Ps1 of scavenging pressure is set by a setting unit 108 from the rack graduation R1 and the combustion index C1 by a predeter mined function. A blade angle is set by the output and the output of the output calculator and compared with the present value of the blade angle, and added by correction to adjust 8 the blade angle.

摘要： PURPOSE: To remove soot by jetting out the gas extracted from the duct connected to a cylinder and led to a waste gas economizer.
CONSTITUTION: The gases extracted from the conduits A - D connected to the cylinder of an diesel engine, or to a waste gas pipe 10, a scavenging air receiver 13, a starting air tank 16 a cylinder gas extrocting hole 14 and a starting air hole 15 for example are selected by a chuange- over means 17. A desired, selected kind of gas is jetted into a waste gas economizer 2 through a conduit 1a and a soot removing nozzle 1. Therefore, the soot in said waste gas economizer 2 can be removed without causing the output of a generator turbine to be decreased by pressure flow of said jetted gas.

摘要： PURPOSE:To make it possible to maintain a high pressure over a wide load range, by connecting a closed container disposed therein a relief valve which opens a fuel pressure exceeding a predetermined value, to a fuel supply pipe through a branch pipe. CONSTITUTION:A fuel from a fuel tank 8 is pressurized by a fuel pump 2, and is then fed into a fuel injection valve 9 through a fuel supply pipe 3 with a given timing before the fuel is injected into a combustion chamber 1. At this time a part of the fuel in the fuel supply pipe is fed into a relief valve 6 disposed in a closed container 5 through a branch pipe 4. Fuel discharged from the relief valve 6 is all trapped in the closed chamber 5 and is then returned into a fuel supply tank 8 through a return pipe 7. Therefore, during normal load operation which is used for the most occasions, the pressure of fuel injection may be made to approach an allowable highest pressure as possible as it can, and therefore, it is possible to obtain a satisfactory cycle efficiency and combustion efficiency.

摘要： PURPOSE:To improve scavenging efficiency by making the upper swirl angle larger than the lower one, providing and twisting the axis of an air path of a scavenging hole in the vertical direction. CONSTITUTION:A scavenging hole 2 consists of a plurality of round hole arranged parallel to the axis of a cylinder. A straight line Y1-Y1 interconnecting the centers O1, O3 of the lowermost and uppermost circles in the outer peripheral portion of said hole 2 is inclined in the opposite direction to that of scavenging swirl stream S, while the upper swirl angle theta3 is made larger than the lower one theta1. In the beginning of opening the scavenging hole 2 by an piston, storing swirl S is given to the scavenging hole since the scavenging hole is provided with the larger swirl angle theta3 so that exhaust in a portion A is blown off. When the scavenging hole is opened to the bottom, the swirl angle is reduced to theta1 to scavenge exhaust in the center of a cylinder.

摘要： PURPOSE:To stop the pressure in an exhaust passage from being abnormally increased and prevent failure of a supercharger by providing a switch valve for opening a branch piping at fixed pressure or more, in the branch piping. CONSTITUTION:Exhaust gas exhausted from an engine flows in an exhaust collecting pipe 4 through an exhaust valve 2 and an exhaust pipe 3. After the exhaust gas is sent to a supercharger 5 and said supercharger 5 is driven after being transformed into static pressure in the exhaust collecting pipe 4, it is exhausted to a chimney 6. When the pressure in the exhaust collecting pipe 4 is abnormally increased and exceeds the set pressure of a switch valve 7, said valve 7 is opened and a part of exhaust gas in the collecting pipe 4 is exhausted to the chimney 6 through a branch pipe 10.

摘要： PURPOSE:To obtain a high scavenge pressure even if an auxiliary motor blower is eliminated, by utilizing a scavenge valve which slides on the inner surface of an engine cylinder and opens and closes scavenge holes, and a scavenge pump chamber in which a partition wall is provided in a scavenge sump so that a closed space is defined below the piston. CONSTITUTION:When the load of an engine is below 50%, a valve 54 is opened while a discharge valve 56 is closed to introduce high pressure air into an air cylinder 52 so that an air piston 53 serves as an air spring 53. As a piston 17 ascends, scavenge air is introduced from a scavenge air inlet chamber 41 into a scavenge air pump chamber 42 through a check valve 44. A scavenge port 12 is closed by a scavenge port valve 51. When a piston 17 descends, pressure in a scavenge chamber 42 increases so that scavenge air flows from the scavenge air pump chamber 42 into a scavenge air pump 19 through a check valve 45. Further, the piston 17 lowers to depress the scavenge port valve 51 overcoming the air piston 53 so that scavenge air flows into the cylinder through scavenge holes 12. When the load of the engine is above 60%, high pressure air in the air cylinder 52 is discharged so that the same scavenge operation is carried out as that in conventional engines.
