Abstract
The invention belongs to the technical field of automobile parts and particularly to a hybrid fuel supply spray nozzle. The hybrid fuel supply spray nozzle comprises a needle valve body and a needle valve. The needle valve is arranged in the needle valve body, the needle valve body comprises an upper portion and a lower portion, and the upper portion of the needle valve body is provided with a positioning hole. The hybrid fuel supply spray nozzle is characterized in that the upper of the needle valve body is provided with a gasoline jet channel and a methanol jet channel. By means of structural improvement, the hybrid fuel supply spray nozzle is applicable to a gasoline and methanol hybrid engine on the basis of meeting the structural requirements of an efficient fuel spray nozzle.
Description
Technical field
The invention belongs to auto-parts technical field, relate in particular to a kind of oil nozzle of mixing feed.
Background technique
Along with the fast development of China's economy and significantly improving of people's lives level, China and become gradually automobile and use big country.The quantity of automobile is just come among numerous families with very high growth rate.As an automobile, use big country, the energy consuming aspect automobile is inevitable considerable.Meanwhile, the consumption of the energy, is also the Tough questions that the whole world faces.Global oil price is soaring, and gas price goes up, and to industry, has caused impact, has also brought no small impact to autoist.Along with rapid economic development, modern more pays close attention to energy-conservation, reduction of discharging, and diesel emission standard is also improving.How when not reducing diesel engine power, reaching further energy-conservation, reduction of discharging has been extremely urgent thing.Due to age relation, what product specification was originally focused on is the watt level problem of diesel engine, and diesel emission and energy loss are not done to more concern.
Fuel injection nozzle matching is by connecting injector assembly, by injector assembly, with oil pump, connect mutually, when oil pump feed, by the spring force in injector assembly and the generation oil pressure of the diesel oil successively entering from oil nozzle high pressure inflow pipeline at seal face, then by the injection of jet orifice of needle valve, enter engine chamber.Because existing needle valve seat surface is too small, cross section at seal face place is too small, oil pressure can not seal up oil completely in the easy generation in seal face place, thereby reduced oil pressure, affected atomization quality, make to burn insufficient, reduced the needle-valve of the common oil nozzle of engine power by needle-valve footpath portion to-and-fro motion in needle-valve body mesopore, implement spray and close.Its mesopore plays dual parts slipper seal and guiding,
Auto-maker or the user of automobile are seeking energy-conservation measure and method.The research history using for two kinds of fuel mix of gasoline and alcohols for many decades, still, due to existing needle-valve body structurally, be mainly to coordinate relating to that single fuel of transmission supplies with.Although needle-valve Sliding velocity and stability are pretty good, also can reach oil nozzle rapid unlatching, close.But be difficult to meet the needs of the mixed fuel engine of novel high speed, high pressure, multi-injection.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of oil nozzle of mixing feed.This oil nozzle, by the improvement of structure, on the basis of topology requirement that meets high-efficient fuel spray nozzle, is applicable to the mixed fuel engine of gasoline and alcohol.
A kind of oil nozzle of mixing feed, comprise needle-valve body and needle-valve, described needle-valve is arranged among described needle-valve body, described needle-valve body comprises upper and lower, top at described needle-valve body is provided with positioning hole, it is characterized in that: on the top of described needle-valve body, be also provided with gasoline injection channel and methyl alcohol injection channel.
