Description

The diesel engine fuel oil Preheating unit

This practicality newly belongs to a kind of device that is used in diesel engine pre-heating oil, to reach the utilization ratio that improves diesel oil, realizes purpose energy-conservation and elimination black smoke effect.

The firing effect of diesel engine not only is related to the power of diesel engine, has also had influence on the quality problems of air ambient.For the diesel engine user, also bad because of burning, oil consumption is big, increases expenditure, and reduces motor working life etc.Especially as the diesel engine that uses on the automobile, to winter,, start difficulty often because of the microthermal climate environment, be one of problem of feeling put about of driver.The reasons for the above problems are that the fuel oil that enters before the diesel engine firing chamber is in the cold oil state always.Injecting in the cylinder through oil atomizer gun, can reduce chamber temperature, influencing the burning quality of diesel oil in cylinder.So, both reduced the power output of motor, again because of incomplete combustion, form black smoke and discharge, polluted air.For addressing this problem, with regard to how the diesel oil that enters before the cylinder is carried out preheating, as a kind of exploration, people have proposed some technological schemes.As application number is the patented technology of " 95217895.8 " and " 94211006.4 ", all is on the pipeline road of diesel engine Electric heating appliance to be set, and diesel oil is preheated processing.Though former structure simply, is installed and is changed and is not easy.The heat that the latter then exists the electric heating wire generation must just heat the diesel oil in the flowing pipe after insulator and tube wall.Therefore, heat is transmitted slow, and thermal loss is also big, causes the thermal efficiency low.Actual effect is undesirable.

The purpose of this utility model just provides a kind of mainly being used on the diesel car, installs to change conveniently, and can be directly to the diesel engine fuel oil Preheating unit heating of the diesel oil in the flowing pipe, that improve the diesel engine fuel oil combustion efficiency.

The scheme that realizes above-mentioned purpose is as follows:

A kind of diesel engine fuel oil Preheating unit is mounted in the high-pressure oil pipe pipeline between the oil connection of the oil atomizer gun of diesel engine and Injection Pump, and the diesel oil in the convection current is by the road entering the oil atomizer gun previous crops device of heating continuously; Heating equipment directly is connected with oil atomizer gun, key is that heating equipment is to be made of a billiard table shape connectedness and a heating pipe, heating pipe is plugged in the billiard table shape connectedness inner chamber, electric heating wire is installed in the inner chamber of heating pipe, has a pair of through hole and billiard table shape connectedness intracavity inter-connection on the intracavity sidewall of heating pipe

Further scheme is the spaghetti that is installed with electric heating wire two electrodes at heating pipe inner chamber oral area closely, make heating pipe in the billiard table shape connectedness of packing into after, guarantee that oil circuit is the seal chamber of a tight sealing.

The heating pipe bottom is shaped on a hexagonal spiral shell head, and body top is shaped on screw thread, in order to using a nut to reach the convenience of heating pipe dismounting and assurance pack into sealing and steadiness in the billiard table shape connectedness.

So just make a diesel engine fuel oil Preheating unit, only need two electrodes of Preheating unit are connected on the car accumulator respective electrode, on circuit, add control switch K.During startup, connect earlier the power supply of Preheating unit, open the oil circuit switch again, directly the flow through electric heating wire of heating of diesel oil is heated rapidly, is sprayed in the cylinder by oil atomizer gun again.Like this, diesel oil obtains the direct heating of electric heating wire, and the oil temperature that raises is for its burning preferably in cylinder provides the foundation.

The utility model has the advantages that:, and they are fixed as one by nut and sealed electrical circle because heating pipe is to insert in the inner chamber of the billiard table shape connectedness that is communicated with oil circuit.Electric heating wire in the heating pipe is in the oil circuit, directly with the diesel oil contact heating, has improved the effect of preheating diesel oil greatly; In a single day electric heating wire in the heating pipe burns out, and only need unclamp the clamping nut on heating pipe top, can change heating pipe.And needn't tear more multi-part in the oil circuit open, thereby change conveniently.The inner chamber of electrode and heating pipe is made insulation processing by spaghetti, and tube chamber is sealed.The safety of use and the seal request of oil circuit have been guaranteed.

Below in conjunction with accompanying drawing,, scheme of the present utility model is specified as an embodiment.

With reference to Fig. 1,2,3,4, the utility model is made of the billiard table shape connectedness 3 of heating pipe 4 and installation heating pipe.Respectively there is one section inipple 2,8 at the two ends of billiard table shape connectedness, join with high-pressure oil pipe 21 and oil atomizer gun 18 respectively and are communicated with, and the center of billiard table shape connectedness is a cavity 12 that can hold heating pipe, and cavity is communicated as one with the inner chamber 11 of the joint at two ends.The cavity of tube chamber 13 for connecting of heating pipe 4.On the cavity lower sides, have to logical through hole 17 gateway that is communicated with billiard table shape connectedness cavity 12 as heating pipe 4 inner chambers 13.Make the diesel oil in the pipeline road after heating pipe 4 heating, enter oil atomizer gun 18 again, the diesel oil in the pipeline is directly contacted with electric heating wire 16.The bottom of heating pipe 4 is shaped on hexagonal spiral shell head 1, and body top is shaped on screw thread, so that packing the heating pipe 4 of billiard table shape connectedness 3 into, by nut 6 the two is tightened together.

With reference to Fig. 2, two joints 2,8 of billiard table shape connectedness 3 are shaped on screw thread, so that with oil atomizer gun 18 and high-pressure oil pipe 21 affixed and connections, the sealing of assurance pipeline road and unimpeded.With reference to Fig. 3, two

electrodes

5,10 of heating pipe 4 penetrate from arbitrary mouth of pipe 15 of heating pipe 4 behind the good electric heating wire 16 of attaching, make electric heating wire place the inner chamber of heating pipe 4, and the part of two electrodes is in outside the mouth of pipe, so that join with 20 the two poles of the earth of the storage battery on the automobile; Outer end from

electrode

5,10 puts spaghetti 14 again, makes spaghetti 14 with the mouth of pipe 15 jam-packs at heating pipe 4 two ends and make encapsulation process, makes it oil-proof.With reference to Fig. 1,2,3, after heating pipe 4 is handled well, above its hexagonal spiral shell head 1, be inserted in seal washer 9, and then billiard table shape connectedness 3 is inserted in from electrode 5 upper ends of heating pipe 4, a pair of through hole 17 that rotates to heating pipe 4 sidewalls is on the line of two joints, 2,8 inner chambers 11 of billiard table shape connectedness 3 and ends; Be inserted in a seal washer 7 from heating pipe 4 upper ends again, compress, promptly make a diesel engine fuel oil Preheating unit with nut 6.

With reference to Fig. 4, the joint 2 of Preheating unit is screwed in the filler opening of oil atomizer guns 18, tighten by the hexagonal spiral shell head 1 on the heating pipe 4, affixed good another joint 8 again with high-pressure oil pipe 21.Two

electrodes

5,10 of heating pipe 4 join with 20 the two poles of the earth of the storage battery on the automobile, a power control switch K19 is installed on the circuit gets final product.

The utility model is mainly used in preheating diesel oil on the diesel car, reaches to improve the oil inflame quality, reduces oil consumption, the purpose of protection air ambient.Power control switch K19 is installed in the operator cabin, with easy-to-operat.
