Concrete enforcement is as follows
As shown in drawings, starting pre-heater of vehicle is made up of storage battery 1, power switch 2, gear chamber shower nozzle 3, controller 4, motor 5, thermal insulation layer 6, oil pump 7, oil distributing pipe 8, piston shower nozzle 9, high temperature heater (HTH) 10, magnetite 11, filter screen 12, housing 13, low-temperature heat 14, connection porcelain vase 15, insulation 16, oil return sensor 17, low-temperature sensor 18, oil distributing pipe inner heating device 19.Controller 4 is connected with the positive and negative polarities of storage battery 1 with power switch 2, and is connected with oil return sensor 17; Motor 5 connects controller 4 by electric wire and is connected with oil pump 7, connects oil distributing pipe 8 on the oil pump.Oil distributing pipe 8 is provided with gear chamber shower nozzle 3 and several pistons shower nozzle 9, and an end and the oil pump of high temperature heater (HTH) 10 are joined, and the other end is connected with low-temperature heat 14, is provided with between oil pump 7 and the high temperature heater (HTH) 10 to be connected porcelain vase 15.Oil return sensor 17, low-temperature sensor 18 are linked to each other with housing 13 by electric wire respectively.Upper and lower two skins of high temperature heater (HTH) 10 are respectively equipped with insulation layer 16.Low-temperature heater 14 is provided with magnetite 11, and the part of its whole top and insulation 16 is filtered net 12 and shrouds.Upper and lower two skins of oil pump 7 are respectively equipped with thermal insulation layer 6.
At first press and be contained in frame and make indoor power switch 2, low-temperature heating device 4 is work a period of times earlier, and this stage is a chilling process.Because ambient temperature is crossed low automobile or the motor resting period is long, lubricant oil in the oil sump 13 all condenses at this moment, can't suck the high temperature heater (HTH) 10 of second stage, as without the low-temperature prewarming process,, form the phenomenon of not having oil on every side when high temperature heater (HTH) exhaustion lubricant oil on every side, because without elementary low-temperature prewarming, it condenses, it is to have caught fire that the motor of this moment had both made, and can cause oil pump for engine oil suction difficulty, easily the accident of tile kilning.And temperature is too high, and it mainly is that engine start is not had help not only to have wasted electric energy, and is made because oil sump is a sheet iron, and it is very slow to transmit heat, and the low-temperature prewarming that refers to here is exactly the lubricant oil in the oil sump can be dissolved to open fully both can.In addition, the running difficulty of motor (referring to the winter low temperature state) has both made and has added or to have changed antifreeze lubricant oil still of no avail, and one is that antifreezing oil can not adapt to low temperature environment; Another reason is, through the parking an of night, all surface of the works of internal structure, all has residual lubricant oil to condense between the surface or bearing shell of parts after starting to quit work, and also is the difficult principal element of running.From the resistance between piston and cylinder sleeve, the resistance of crank mechanism, resistance (this resistance that is meant is that machine oil is paid the Adhesion force on parts) between gear chamber tooth and gear thus hold up into the engine running difficulty, this device is designed, low-temperature prewarming is to consider for the power supply of storage battery, we can not be too much the electric energy of loss storage battery, can reach the lubricant oil of 7-8 ℃ oil sump, controller 4 can stop its work.
The just dissolved lubricant oil process sensor of opening is to controller, control can be worked by actuating motor 5 automatically, drive oil pump 7 (this device can design the front end of oil sump or both sides all can) will just dissolved lubricant oil inspiration high temperature heater (HTH) after the oil pump work in 10, the high-temperature heating equipment suction inlet is provided with magnetite 11 and considers net 12 and prevents that iron filings and oarse-grained foreign material from entering, in order to avoid stop up 9 heating equipments of jet through special, can in the short time lubricant oil be heated to 80-100 ℃ at the utmost point, this installs 10 outer surfaces and is provided with thermal insulation layer 16 in addition, and it can be separated with subzero oil two temperature in the oil sump.This design is in order to reduce heat dissipation, there is no need the temperature of the lubricant oil of oil sump is done so high, also be for saving power, solve topmost problem with minimum electric weight, both heat supplies of piston-cylinder, crank mechanism and gear chamber, this device can attach together with low-temperature heat 14 and high temperature heater (HTH) 10, and there is thermal-protective coating 16 joint, be in order to reduce shared space proportion, the sump lubrication oil capacity required to motor do not have much influences.
When being sucked into, lubricant oil require temperature 80-100 ℃ of effect (to be located at housing 13 outsides before high-temperature heating equipment 10 arrives oil pump through heating as oil pump through oil pump, oil pump should add thermal insulation layer 6) afterwards motor is first with low-speed running by controller 4 controls, with oil distributing pipe 8 and oil pump 7 preheatings in advance, the heating equipment that be embedded in the oil distributing pipe 8 this moment is not necessarily worked, they could be by controller 4 startup work after having only low-temperature prewarming device 14 to quit work, because controller can not wait until that sump lubrication oil dissolves fully, but lubricant oil soon dissolve before with regard to actuating motor work, this design is for the problem of saving time.
Oil pump 7 and oil distributing pipe 8 self-preheatings after several seconds motor 5 by control gear 4 start run up after, with High Temperature High Pressure lubricant oil is delivered to oil distributing pipe, the heating equipment of burying underground in the oil distributing pipe can be heated to its 2 times, as reaching requirement from the oil pump temperature.Heating equipment 19 in the oil distributing pipe can not worked, but be lower than design temperature and require its work automatically, lubricant oil is delivered to wherein installation side in housing all of the installation of 6 shower nozzles 9 and oil distributing pipe of seven shower nozzles 3,9 of being located on the oil distributing pipe respectively behind oil distributing pipe 8, crux be shower nozzle installation should with the normal operation that do not influence connecting rod and no matter bent axle go to any angle and the lubricant oil of shower nozzle ejection, the space of swashing the skirt section that being mapped to live cold key seat and piston can both be as the criterion.
Scorching hot lubricant oil at first carries out preheating gradually to whole body with piston.A surplus gentle lubricating oil part flows downward to cylinder sleeve along the piston skirt, initial preheating lubricant oil can trickle very slow, have packing phenomenon, can be watered down by the high hot lubricating oil dilution of the thing followed, flow to behind the cylinder sleeve also to its preheating, the lubricant oil that cylinder sleeve and piston are adhered to is dissolved, to reduce its resistance to motion, also played simultaneously the tightness that increases between piston and cylinder sleeve, because piston that is heated and piston ring expand because of being heated, lubricant oil then can flow downward along cylinder sleeve and watt locate through casing wall to main shaft seat, also can be to its preheating, a main shaft seat watt box is heated, and contained lubricant oil is also dissolved between the main shaft, lose viscosity, also can easily turn round in the main axle bush place like this, flowed to oil sump again by the lubricant oil of exhaustion heat at last.
Another part lubricant oil can trickle downwards along the connecting rod place, to the Lian Wachu of connecting rod, bent axle and connecting rod bearing shell seat are heated.Reason is the same.
It mainly is that the gear chamber of motor is carried out preheating to establish a shower nozzle 3 on oil distributing pipe 8 in addition, this shower nozzle 3 is established three apertures, is become the injection of three fine rules to the different amount of gear chamber, its major part is heated,, reaches the purpose easily that turns round to reduce the interlock resistance between tooth and gear.Remaining lubricant oil is still continued heating after getting back to oil sump, go up a program repeatedly, at this moment engine cylinder-body has served as interim insulation cover, influence was little when the external temperature variation was worked to preheating, and all be that running gear to crux carries out direct preheating, both having made engine cylinder-body is ice-cold also can easily piloting engine, after preheating is finished, the sensor that is contained in enclosure interior can measure the temperature of lubricating oil return, when for example reaching 10 ℃, represent preheating to finish, signal is passed to controller, the controller prompting of sounding, notice preheating 9 is finished, finish warm, can reach, start, during machine time-20-30 ℃ of 2-3 minute-30-50 ℃ 5-6 minute, do not consume how many electric weight of storage battery yet.
This device is to be example with the regular engine oil, the non-congealable oil better effects if of if can annotating.In addition, after said process is finished, can also be connected with the lubricant oil oil circuit of motor, after the preheating of finishing the engine interior critical piece, controller can open automatically engine oil gallery valve, close and swash the mode spatter or spray High Temperature High Pressure, directly the lubricating oil path to motor carries out preheating, and its program belongs to the preheating insulation state.
