Abstract
An electric control fuel injector is used for reducing fuel consumption and waste gas emission of a diesel engine. The technical scheme of the electric control fuel injector includes that the electric control fuel injector is mounted on a high-pressure direct injection diesel engine, and the diameters of fuel injection nozzles range from 0.12 millimeter to 0.18 millimeter. By the aid of redesign of the structures of the fuel injection nozzles closely related to emission and fuel economy of a vehicle, the fuel spray atomization of the electric control fuel injector is effectively improved, fuel consumption and waste gas emission of the diesel engine are greatly reduced, and the electric control fuel injector can guarantee that emission of the diesel engine meets the requirements of euro IV emission standards when being used on the diesel engine.
Description
Technical field
The utility model relates to a kind of high pressure direct injection diesel engine electric-controlled fuel injector, belongs to technical field of engines.
Background technique
Along with the fast development of automotive industry, automotive exhaust gas and fuel economy more and more are subject to people's attention, and in order to satisfy fuel economy rules and emission regulation demands, diesel fuel injection system constantly improves.The experiment and studies show that, the structure of diesel engine electric-controlled oil ejector nozzle opening and vehicular discharge and fuel economy all have substantial connection, and the nozzle opening structure of existing electric-controlled fuel injector is all undesirable, can not satisfy low oil consumption and low emission standard-required, remains further to be improved.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of energy to satisfy the electric-controlled fuel injector of low oil consumption and low emission standard-required.
The alleged problem of the utility model realizes with following technical proposals:
A kind of electric-controlled fuel injector, it is installed on the high pressure direct injection diesel engine, and the diameter of the nozzle opening of described oil sprayer is 0.12～0.18 millimeter.
Above-mentioned electric-controlled fuel injector, the number of described nozzle opening are set to 7, and the axis of 7 nozzle openings is along evenly distributing with the coaxial same conical surface of nozzle holder, and the cone angle of the described conical surface is 153～159 degree.
The utility model all has the structure of the nozzle opening of substantial connection by redesign and vehicular discharge and fuel economy, effectively improved electric-controlled fuel injector oil bundle nebulization efficiency, greatly reduce the oil consumption and the toxic emission of diesel engine, on diesel engine, use, can guarantee that diesel emission satisfies the requirement of Ou Si standard.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an outline drawing of the present utility model;
Fig. 2 is the utility model nozzle opening structural representation.
Each label is among the figure: 1, housing; 2, nozzle opening.
Embodiment
Enhancing along with the countries in the world environmental consciousness, the Abgasgesetz increasingly stringent, also more and more higher to the emission request of diesel engine, diesel engine generally adopts high-pressure common rail fuel injection technology at present, oil sprayer is as strength member in the system, and its nozzle opening structure plays an important role.
Referring to Fig. 1, Fig. 2, the utility model provides a kind of electric-controlled fuel injector, its redesign determines that the technical parameter of nozzle opening is: the nozzle opening diameter is 0.12～0.18 millimeter, flow is 760 ml/min, the quantity of nozzle opening 1 is 7, and oil bundle cone angle is 153～159 degree, and maximum can produce the injection pressure of 1500～2000bar, be provided on the diesel engine of 82～87 millimeters of cylinder diameters, 84～96 millimeters of strokes, 84～120 kilowatts of power and use, discharging guarantees to satisfy the Ou Si standard.
