Abstract
A gasoline engine fuel oil supply system comprises a gasoline tank, a fuel oil pump, a fuel oil common rail and nozzles, wherein the gasoline tank, the fuel oil pump, the fuel oil common rail and the nozzles are sequentially connected through pipelines. The gasoline engine fuel oil supply system is characterized by further comprising a low-boiling-point matter storage box, an output pipeline of the low-boiling-point matter storage box is connected with the pipeline between the gasoline tank and the fuel oil pump through a flow control valve. According to the gasoline engine fuel oil supply system, flash boiling spray is formed by adopting the mode that flash boiling of low-boiling-point matter drives traditional gasoline to be atomized, external energy sources do not need to be supplied, and the heat utilization efficiency of an engine is improved; a special nozzle structure is not needed, so that the cost of an oil spray system is reduced; and installation is easy, operation is convenient, and only a low-boiling-point matter supply pipeline need to be additionally arranged in the fuel oil supply system.
Description
Technical field
The present invention relates to technology of gasoline engine field, particularly a kind of gasoline engine fuel feed system.
Background technology
The extensive application of gasoline engine direct-injection system, enhances the transient response ability of gasoline engine, also improves its combustion simultaneously
Oily economy.But, directly jetting gasoline engine is difficult to start under cold start-up operating mode and exhaust particulate thing discharges too high problem always
It is academia, the emphasis of industrial quarters research.Research shows, realizes fuel oil and dodges boiling spraying, can show under identical engine operating condition
Write lifting fuel-oil atmozation, evaporation effect, reduce gasoline engine exhaust emissions, the effect of lifting fuel economy.At present, own
Can form such technology dodging boiling spraying, be substantially and realized by the scheme of heated fuel oil, that is, by way of heating
Improve the degree of superheat of fuel oil, thus forming sudden strain of a muscle boiling spraying.Although this scheme can significantly improve fuel-oil atmozation and evaporation effect,
In engine cold-start, it usually needs extra electrical heating, Electric heating typically requires heated nozzle and controls fuel oil temperature, greatly
Big increase nozzle design and manufacture cost；Electrical heating fuel oil temperature, needs to use external power source, inadequate environmental protection and energy saving；
Content of the invention
The technical problem to be solved in the invention is to provide a kind of gasoline engine fuel feed system, and this system is a kind of to be adopted
In fuel oil supply system, interpolation low-boiling point material is realized dodging boiling spraying, thus power without external power source to carry out to fuel oil adding
Heat；
1. adopt original no heating function nozzle, injection system cost need not be increased；
In order to realize the purpose of the present invention, technical scheme is as follows：
A kind of gasoline engine fuel feed system, including the gasoline fuel tank being sequentially connected by pipeline, fuel pump fuel common-rail
And nozzle, its feature is also low-boiling point material storage bin, and the output pipe of this low-boiling point material storage bin is through a flow control
Pipeline between valve processed and described gasoline fuel tank and fuel pump is connected.
As usual add conventional gasoline in described gasoline fuel tank, described low-boiling point material storage bin adds low boiling
Point material, when directly jetting gasoline engine is in cold start-up, driver or driver open flow control valve, control low-boiling point material and from vapour
The appropriate mixing of gasoline of fuel tank output, it is ensured that fuel oil can form sudden strain of a muscle boiling spraying really, promotes the burning of electromotor.Due to fuel oil
Middle low-boiling point material reaches enough degrees of superheat, makes fuel spray be internally formed microexplosion phenomenon, and rate is initially formed sudden strain of a muscle boiling spraying, thus
Realize the sudden strain of a muscle boiling spraying of overall spraying.Operating condition according to electromotor and running status, change the size of flow control valve,
Realize dodging boiling spraying using minimum low-boiling point material, reduce the consumption of low-boiling point material.
The invention has the beneficial effects as follows：
The present invention forms sudden strain of a muscle boiling spraying using dodging of low-boiling point material by the way of boiling drives conventional gasoline atomization, need not be outside
Energy resource supply, improves engine thermal utilization ratio；Without special nozzle structure, reduce injection system cost；Install simple,
Easy to operate, only need to add the feeding pipe of low-boiling point material in fuel oil supply system.
Brief description
Fig. 1 is the structural representation of gasoline engine fuel feed system of the present invention.
Specific embodiment
For making the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with instantiation, and with reference to attached
Figure, the present invention is described in more detail.
First refer to Fig. 1, Fig. 1 is the structural representation of gasoline engine fuel feed system of the present invention.As seen from the figure, the present invention
Gasoline engine fuel feed system, including the gasoline fuel tank 1 being sequentially connected by pipeline, fuel pump 3, fuel common-rail 5 and nozzle 6,
Also has low-boiling point material storage bin 2, the output pipe of this low-boiling point material storage bin 2 is through flow control valve 4 and described vapour
Pipeline between fuel tank 1 and fuel pump 3 is connected.
As usual add conventional gasoline in described gasoline fuel tank 1, add low in described low-boiling point material storage bin 2
Boilers, when directly jetting gasoline engine is in cold start-up, the gasoline in gasoline fuel tank 1 exports along pipeline, and driver or driver open
Flow control valve 4, and control the low-boiling point material from low-boiling point material storage bin 2 output proper with the gasoline that gasoline fuel tank 1 exports
Work as mixing, enter electromotor through fuel pump 3, fuel common-rail 5 and nozzle 6 it is ensured that fuel oil can form sudden strain of a muscle boiling spraying really, promote to send out
The burning of motivation.Because low-boiling point material reaches enough degrees of superheat in fuel oil, fuel spray is made to be internally formed microexplosion phenomenon, rate
It is initially formed sudden strain of a muscle boiling spraying, thus realizing the overall sudden strain of a muscle sprayed boiling spraying.Operating condition according to electromotor and running status, change
The size of vari- able flow control valve, realizes dodging boiling spraying using minimum low-boiling point material, reduces the consumption of low-boiling point material.
Experiment shows, apparatus of the present invention form sudden strain of a muscle boiling using dodging by the way of boiling drives conventional gasoline atomization of low-boiling point material
Spraying, without extra power supply, improves engine thermal utilization ratio；Without special nozzle structure, reduce injection system
Cost；Structure is simple, installs and easy to operate, and the feeding pipe that only need to add low-boiling point material in fuel oil supply system is
Can.
