Description
Art
The present invention relates to a kind of thermal insulating type automobile engine preheater.This thermal insulating type automobile engine preheater forms primarily of thermo jug, water pump, valve and water pipe.
Background technique
North of China is cold for winter, and usually the water freezes as it drips, and such as the Harbin lowest temperature once reached-52.3 DEG C.During low temperature, vehicle accumulator there will be electricity shortage, and spark-discharge fire is weak, and simultaneously fuel oil was not easily atomized and lighted winter, and therefore a lot of vehicle there will be the phenomenon that difficulty in starting maybe cannot start.And cold start-up oil consumption consuming time, tail gas pollution is serious, and the wear extent of cold start-up parts is equivalent to normally travel 300km.In addition, easily form carbon deposit during low temperature in firing chamber, cause the phenomenons such as piston ring sticking, compressive force is not enough, and engine power declines.Therefore, temperature important in inhibiting when improving automobile engine starting how is fast studied.
Automobile engine preheater is mainly divided into " gas " hot preheater, " water " hot preheater and " oil " hot preheater three class both at home and abroad at present.
" gas " hot preheater carries out preheating to car engine air admittance.This type of Motor Engine Cylinder intake air preheater is arranged in the intake manifold of motor car engine, intake air preheater comprises ribbon heater and installs the preheater seat of ribbon heater, be fixed on and be positioned on the porcelain pad basin assembly of preheater seat frame in the framework that ribbon heater is placed in preheater seat, preheater seat frame is provided with the positive source tenminal block and power cathode tenminal block that connect ribbon heater two terminal.Air enters cylinder by intake manifold, and when starting preheater, heating element generates heat, makes air heats enter in cylinder, and the gas and the fuel mixture that enter engine cylinder-body are fully warmed-up.
Cooling liquid heats by " water " hot preheater electrical heating method, thus makes the overall preheating of motor car engine.Antifreeze liquid in body can be improved about 40 DEG C in 20 minutes by such preheater connection 220V power supply.Its advantage is that volume is little, and the distance between particularly importing and exporting only has 3.5cm, and take up room so actual very little, install very easy, can directly be connected on warm braw Circulation pipe or short circle pipe, nearly all automobile does not need to change former car pipeline.
" oil " hot preheater carries out preheating to fuel feeding.Structure comprises oil inlet pipe and the filter cleaner that is communicated with it and heater plug.Feature is: the solenoid valve pipeline between filter cleaner and heater plug being connected with a control heater plug fuel feeding, solenoid valve two ends are connected with filter cleaner and heater plug respectively by oil pipe.Its advantage is: when needing heater plug to work, and connects solenoid valve circuit, makes its valve open, and diesel oil passes through solenoid valve through filter cleaner, then through oil inlet pipe supply heater plug; When heater plug does not work, disconnect solenoid valve circuit, valve closing, the oil circuit towards heater plug is disconnected, and bears the oil pressure towards heater plug by solenoid valve, greatly reduces because the fault of leakage of oil does not sternly appear in ball valve sealing.
A few class automobile engine preheater all adopts electric energy conversion to become heat energy thus reaches preheating object above.Wherein most of preheater (being mainly " water " hot type) adopts external 220V power supply mode of heating, and such preheater consumes outside electric energy, and operating process is loaded down with trivial details, and will near power supply.Separately have fraction to adopt Vehicular accumulator cell heating, the lead-acid battery that current automobile extensively adopts, during winter low temperature, capacity of battery diminishes, and efficiency for charge-discharge is low, therefore adopts the low energy consumption of the storage battery efficiency of heating surface large.
In view of above analysis, current automobile engine preheater development trend mainly contains and improves thermal transition efficiency and reduce thermal loss." water " hot type preheater extensively adopted at present adopts electrothermal wire heating mostly, and heating efficiency is low.Existing part research at present adopts electromagnetic inductive heating principle, and the high-frequency alternating magnetic field produced by electromagnetic induction coil forms eddy current on the surface of heater, and these eddy current overcome the resistance acting of heater, give out heat, thus reach direct-fired object.
The thermal insulating type automobile engine preheater that the present invention relates to utilizes energy during thermo jug preservation engine high-temperature, and uses when being supplied to motor car engine low temperature.
Summary of the invention
In motor car engine work after 10 minutes, coolant temperature can reach 90 DEG C, and after engine stop work, coolant temperature is reduced to ambient temperature gradually.Therefore, the present invention adopts the mode store heat of series connection thermo jug, during for motor car engine cold-starting.
The technical solution adopted for the present invention to solve the technical problems is: thermal insulating type automobile engine preheater forms primarily of by thermo jug, water pump, valve and pipeline.Thermal insulating type automobile engine preheater belongs to " water " hot preheater, and installation method and conventional pre-heater are substantially identical, is arranged on car engine cooling system, is connected in lesser circulation by preheater.
When motor car engine quits work, coolant temperature is the highest, now starts preheater switch, pump working, in engine-cooling system high temperature coolant and insulation fill with in the cooling liquid of lower temperature complete and once exchange.
When motor car engine normally works, thermal insulating type engine preheater does not work, and does not also affect engine-cooling system and normally works.
When engine temperature is lower, when difficulty in starting maybe cannot start, start preheater, in engine-cooling system the cooling liquid of lower temperature fill with insulation in the higher cooling liquid of temperature complete and once exchange, the cooling liquid of higher temperature makes engine cylinder-body rapid temperature increases, thus plays the effect of preheating.Need certain hour because engine coolant cools naturally, therefore about again strike sparks without the need to preheating in half an hour after engine misses; And the insulation effect of thermo jug is also limited, generally can to maintain in 24 hours temperature at about 50 DEG C, after starting preheater, temperature cylinder can bring up to more than 20 DEG C, therefore can have good pre-heat effect in 24 hours.
The major advantage of thermal insulating type automobile engine preheater is: without the need to ABAP Adapter, does not limit by power supply; Power consumption is few, and only need storage battery power supply to be circulated by hot and cold water, energy consumption almost can be ignored.The thermal insulating type automobile engine preheater that the present invention relates to is compared with electric heating type preheater, energy-conservationly can reach more than 80%, even and if ambient temperature is very low, the temperature that motor normally starts also can be reached, even fast a lot of than electrically heated on preheat time.
