Description
Technical field
The utility model belongs to automobile technical field, relates to the supply preheating of motor car engine fuel and protection device for oil pump.
Background technique
Automobile is when using fuel, if fuel own temperature is higher than ambient temperature when spraying into cylinder, this is conducive to the aerial gasification of fuel, mixes better with air, and the explosive force of motor can be better, and burning and exhausting is more clean.
Especially to using first (second) alcohol to be the motor of fuel, oil feed pump is perishable is the difficult problem be never resolved, find in practice to use first (second) alcohol to be that the engine fuel injection pump of fuel is when the operating at voltages higher than certain, there is corrosion in electrode, the moving element serious wear such as oil pump bearing carbon brush cause shorten working life, if can ensure that oil pump normally works when operating voltage is reduced to certain voltage, greatly can extend again oil pump working life, make engine fuel system more reliable and more stable.Existing patented technology is only all to fuel preheating, and have larger change to the oil circuit of former car and circuit, as the preheating structure of Chinese patent 201220018716.0 1 kinds of automobile oil rail injectors, oily rail is wanted to the destructive transformations such as perforate, and only have a kind of function of fuel preheating.
Model utility content
The purpose of this utility model is exactly propose a kind of simple and practical solution for above-mentioned technical background.On the basis not changing the original control circuit oil circuit of automobile, realize fuel preheating, oil pump is protected, and reduces the object of fuel consumption.Fuel 11% (m100 methanol fuel) is about with installing this device under operating mode than not installing prosthomere.
The utility model object realizes by following technical proposal: a kind of automotive fuel preheating and protection device for oil pump, as shown in Figure 1, it is characterized in that, device upper part (1) is identical just as oil nozzle oil inlet end physical dimension outward, be convenient to be connected with oily rail oil outlet, lower part (2) is identical with oily rail oil outlet profile physical dimension, be convenient to be connected with oil nozzle oil inlet end, Preheating unit has heating resistor (3) and heating resistor mounting hole (4) and is arranged in heating resistor mounting hole (4) both sides and Fuel Fractionation hole (5) orthogonal and Uncrossed with heating resistor mounting hole (4).

Automotive fuel preheating and protection device for oil pump, is characterized in that, heating resistor (3) is in Preheating unit heating resistor mounting hole (4) central position, is drawn out to outer connection by wire.
Automotive fuel preheating and protection device for oil pump, is characterized in that, selecting suitable heating resistor parameter to realize allowing oil pump normally work simultaneously again can to the object of fuel preheating.
Automotive fuel preheating and protection device for oil pump; it is characterized in that; fuel preheating and protection device for oil pump are between former car oil nozzle oil inlet end and oily rail oil outlet end; each oil nozzle one_to_one corresponding one; and after the series connection of each heating resistor again with oil pump series-fed, realize oil pump overload protection function.
Automotive fuel preheating and protection device for oil pump, is characterized in that, in engine operation process, always Preheating unit is in fuel preheating working state.
Automotive fuel preheating and protection device for oil pump, is characterized in that, do not do destructive transformation, do not increase former car storage battery load to existing vehicular engine circuit oil circuit.
Automotive fuel first flows through this Preheating unit from oily rail oil outlet outflow and enters oil nozzle oil-feed port again, and between each automobile oil nozzle with oily rail, have a corresponding Preheating unit, enter oil nozzle again after all fuel entering oil nozzle oil-feed port all obtains preheating when motor runs.Realize before spraying into engine cylinder the shortest distance that flows through to the timely preheating of fuel.
The hot-swap feature of Preheating unit realizes like this, heating resistor is placed in device central position, current direction and fuel flow direction are orthogonal and do not intersect, fuel flows through Preheating unit by multiple tap hole being placed in heating resistor mounting hole both sides respectively, and the heat transfer by device in flow process realizes heat exchange.
The parameter of selecting properly heating resistor can realize fuel preheating simultaneously oil pump also can normally work and also there is overload protective function to oil pump.

Embodiment
As shown in Figure 1, design and produce a kind of Preheating unit, upper part (1) profile of Preheating unit is identical with oil nozzle oil inlet end, to insert oily rail oil outlet end reliably to connect, lower part (2) profile is identical with oily rail oil outlet end, oil nozzle oil inlet end is facilitated reliably to put on connection, Preheating unit has hot-swap feature, heating resistor mounting hole (4) can be placed in by electrified regulation resistance (3), the heat transfer making the material of heating equipment own is utilized to realize heat exchange by the Fuel Fractionation hole (5) being arranged in heating resistor mounting hole (4) both sides, oil nozzle oil inlet end is entered again after improving the temperature of fuel.
Each oil nozzle is worn a fuel preheating and protection device for oil pump and then is inserted oily rail oil outlet, and former car oil nozzle to be put on after Preheating unit as shown in Figure 5.
After access oil pump of connecting again after heating resistor (3) terminal of each fuel in advance and in oil pump protection thermal being connected by wire is insured, oil feed pump is powered.As shown in Figure 6.
Working principle: adopt repeatedly several times at ACC when engine cold-start---ON switch electric switch operates, period pauses several seconds, driver can hear oil pump pump oil operation sound and not ato unit operation, such operation only has pump oil process and does not have injection process, because fuel is static in oil nozzle oil inlet end Preheating unit, Preheating unit fuel can make pre-thermal resistor and heat exchanger heating because of the operating current of oil pump pump oil process, thus cause the fuel in Preheating unit to be heated to the temperature being easy to light, at this moment START ato unit gear ato unit is got to again, for using the motor that methyl alcohol is fuel, there is the positive effect improving cold start-up.When the fuel after engine start in Preheating unit is flowing, and each Preheating unit heating electric power only has several watts, so fuel temperature can not infinitely raise, the temperature being stabilized in a safety is run.It is more steady that preheating of fuel makes motor run, and preheating compensate for the gasification latent heat of fuel, and fuel straying quatity also reduces to some extent than not preheating, serves the effect of fuel saving.Pre-thermal resistor simultaneously in Preheating unit and oil pump are coupled in series, and under the prerequisite not increasing storage battery load, the electric power of pre-heat loss creates certain voltage drop thus reduces the operating voltage of oil pump on pre-thermal resistor.The pre-thermal resistor parameter of choose reasonable just can play and both ensure that oil pump normally worked, simultaneously pre-heating fuel again, and the effect of protection oil pump, during switch-off, FP Fuel Pump Relay power-off Preheating unit also stops fuel preheating.
The present utility model realizes the protection to preheating of fuel and oil pump under having the prerequisite not destroying former car circuit and oil circuit, structure is simply easy for installation, the advantage that highly versatile practicability is high.At a buick excelle, actually on Cherry's son of the east car to use, safety traffic 60,000 km(Buick cars) and 30,000 5km(Cherry son of the easts).
