Description
Technical field
This utility model relates to motor vehicles, especially relates to a kind of engine crank case ventilation pipeline heating device.
Background technology
Along with country's increasingly stringent to automobile emission regulation, engine for automobile is all to use closed crankcase ventage
System, sends into motor intake manifold gas out in crankcase by the breather valve on valve cover top, returns burning, this
Sample both can reduce the discharge of crankcase pollutant, can improve again the economy of electromotor.
But, the northern area winter temperature in China is often less than-40 DEG C, after the long-time high-speed cruising of vehicle, from song
In axle box, gas out flows in crankcase bleed pipe, flow to by outside air input air filter delivery conduit (should be: outer
Boundary's cold air input air filter delivery conduit), air filter delivery conduit converges cool ambient air and crankcase gas out, enters back into
Motor intake manifold, because air gathers, is easily caused air filter delivery conduit and freezes with crankcase bleed pipe intersection and block up
Plug crankcase bleed pipe, causes the bent axle hypertonia in engine crankcase, and excessive pressure reduction causes oil sealing leakage of oil, time serious
Oil sealing is even made to come off, damage electromotor.Prevent the work no one always that the air pipeline of engine crankcase freezes in recent years
Capturing, someone considers to be demarcated by ECU, adds circuit and controls to solve the crankcase ventilation system of electromotor in extremely cold area
Ice formation issues, but not all area all can occur that ice blocks up phenomenon, is required for this ventilation preventing engine crankcase
The device that pipeline freezes, therefore its selling market is confined to extremely cold area, for drawing a snake and add feet to it the most a little, increases not
Necessity and cost.
Summary of the invention
The purpose of this utility model is to provide a kind of engine crank case ventilation pipeline heating device, and it passes through heater
In critesistor control the temperature of intersection, when low temperature, intersection is heated, thus avoids engine crankcase
In low temp area, ventilation duct occurs that ice blocks up situation, the most pre-anti-icing stifled phenomenon, so can save the relevant work of many demarcation
Make, selectively can use in different areas again.
The purpose of this utility model is achieved in that
A kind of engine crank case ventilation pipeline heating device, feature is: include heater, delivery conduit heater support
And crankcase bleed pipe, heater is made up of heater housings, copper pipe, critesistor and silica gel hose, " T " font and by thermoplastic
The heater housings that hard tube is made is made up of Socket casing and heated shell, the heating shell that Socket casing is through before and after being perpendicular to
Body, is provided with anelectrode, the negative electrode connected with 12V power supply on automobile storage battery, copper pipe and heating in the socket cavity of Socket casing
The inwall of housing is in closely cooperating, at the middle part inwall of heated shell in the side of Socket casing, the middle part of heated shell
It is provided with the critesistor groove of indent between wall and the outer wall of copper pipe, the inwall of critesistor groove is fixed with silica gel hose,
Being provided with the critesistor being close to copper pipe outer wall in critesistor groove, silica gel hose encases critesistor from the outside with isolation temperature-sensitive electricity
Resistance and heated shell, critesistor connect with electric fuse after two ends pass through wire respectively with the anelectrode in socket cavity, negative electricity
The most connected, the centre of copper pipe is that critesistor is for heating the heating chamber flowing through gas；Outer wall at the inlet end of heated shell
If with the bulge loop that the outer wall of outlet side is equipped with arterial highway band chamfering, forming heater air inlet corrugated tube and heater and give vent to anger ripple
Pipe, at the bottom of the inlet end outer wall for inspiration cool ambient air of air filter delivery conduit is provided with the delivery conduit heater of tubulose
Seat, the inwall at delivery conduit heater support is provided with gives vent to anger the supporting base corrugated tube of corrugated tube with heater, heated shell
The heater of outlet side give vent to anger the base corrugated tube of corrugated tube and delivery conduit heater support according to the connection of interference fit
Mode carries out ripple connection so that the outlet side of heater is arranged on the delivery conduit heater support of air filter delivery conduit,
The outlet side of crankcase bleed pipe according to the connected mode of interference fit, connected adding of inlet end with heated shell by ripple
Hot device air inlet corrugated tube is fixed together.
The shape of cross section of copper pipe be top layer be the cup head loop configuration of platform, in order to silica gel hose and critesistor
Axial restraint.
One it is provided with for the arrow indicating pipeline to install trend in the middle of the outer wall of heated shell.
Delivery conduit heater support is circular tube shaped.
This utility model is owing to being additionally arranged a heater at crankcase bleed pipe and air filter delivery conduit, in heater
Critesistor is made up of metal material, and the resistance value of critesistor is propped up and changed along with the change of ambient temperature, constant at voltage
In the case of, the resistance value of critesistor is proportional with ambient temperature, the resistance value of critesistor with ambient temperature rising and
Increase, reduce with the reduction resistance of ambient temperature.After 12V power supply connected by critesistor, when the temperature of the surroundings is low, temperature-sensitive electricity
The resistance value of resistance is less, and the heat that critesistor sends is relatively big, and the thermal energy conduction that critesistor sends, to copper pipe, makes copper pipe send out
Heat, it may be assumed that the crankshaft ventilation tube of electromotor and intersection's heating of air filter delivery conduit, heats the gas flow through, has reached heating
Purpose, thus prevent the party of cool ambient air and engine gas and occur that ice blocks up, and prevents the crankcase ventilation of electromotor
Pipe occurs that ice blocks up phenomenon；When ambient temperature is the highest, the resistance value of critesistor is the biggest, and the heat that critesistor sends is very
Little, the heats of heater is relatively low, is nearly at off position.
Critesistor is connected with copper pipe and silica gel tube by tin cream, so can directly transmit heat to copper pipe, with prevention
The crankshaft ventilation tube of electromotor freezes with the intersection of air filter delivery conduit, again can be by the temperature of heat insulation reduction heater housings
Degree.The two ends of heater lead to delivery conduit heater support and crankcase bleed pipe respectively according to the connected mode of interference fit
Crossing ripple to connect, such structure function is: 1, make heater and delivery conduit heater support and crankcase bleed pipe not
Easily pull-off is out；2, it is easily installed in dismounting, it is possible to promote the performance of part.
Therefore, this utility model has and controls the temperature of intersection by critesistor in heater, when low temperature pair
Intersection carry out heating thus avoid engine crank case ventilation pipe to occur in low temp area ice blocks up situation, the most pre-anti-icing
Stifled phenomenon, save the related work of many demarcation, can use in the environment of inclement condition, simple in construction, be easily achieved, exempt from
The advantage safeguarded, this utility model had both adapted to the overall situation that the most domestic weather differs, and can guarantee that again what vehicle used at Han Qu
Reliability.
