TH4226B - Direct injection diesel engine - Google Patents

Abstract

This invention involves direct injection diesel engines. In which the intake valves and fuel injectors are located on the cylinder head, the valve seat of the intake valve is placed on the surface of the combustion chamber. at the cylinder head in such a way that the basin surrounding the seat of the tongue makes a loud noise said to be able to bring the air that is sucked into the fuel injector and there is a gap around the fuel injector which can be contacted with the basin around the valve seat to receive cool air that is sucked in to cool the fuel injectors

Claims (4)

1.Direct injection diesel engine Which consists of Cylinder head with intake and nozzle mounting holes Has a mushroom-shaped tongue For opening / closing the said intake channel And has a fuel injector attached It is located within the nozzle mounting cavity with a reservoir for air flow between the surface of the combustion chamber. With the shoulder pads of the said intake compartment By creating a shoulder spacer Such a basin collapsed from the surface of the combustion chamber as Said of the aforementioned cylinder head And there are basins for receiving air currents Between the open end of the said nozzle mounting hole and the surface of the said combustion chamber With such open end having a collapsed part Entering from the surface of the aforementioned combustion chamber Basins for the air flow And basins for receiving current Such air Were arranged to communicate with each other Make a space between the said nozzle and the said fuel injectors. By allowing the said gap to contact Basins for receiving such air currents The width of the loudspace Say it must be wide enough so that at the beginning of the suction cycle The sucked air can flow into the gap. Through the air flow basins and the air flow basins respectively for cooling from the said fuel injectors A characteristic feature of the components is (a) a conical basin for receiving air currents. (cone-shaped) (b) The injection hole at the front end of the fuel injector is positioned in the air chamber. In a manner not to file Out of the surface of the combustion chamber enters the combustion chamber and (c) the injection hole can be considered in the middle of the receptacle basin Cone-shaped air stream 2.Direct injection diesel engine According to claim 1, where the aforementioned intake and the part near its exit (entrance to the combustion chamber) is made up of an eddy current and a section. The rest of the said intake since the extension of the room. The eddy current To its entrance, it is a channel through the eddy chamber, the surface of which is formed From circulation with the axis of the intake valve as the center And the passage is connected in line with the surrounding surface of the eddy chamber. 3.Direct injection diesel engine According to claim 1, where the cylinder head has an additional component, there is an exhaust port and an exhaust valve for the said exhaust channel. The shoulder pads of the tongue cough It is created as a basin on the surface of the room. Such combustion And the cylinder head said Causing a vapor reservoir Broken up between The surface of the combustion chamber and the seat spacer of the said exhaust flange. The exhaust chamber is in contact with the air chamber. 4.Direct injection diesel engine According to any one of the 1 to 3 claims Where the injectors of the fuel injectors are placed in the air chamber (4 claims, 2 pages, 4 photos).
