Abstract

The utility model discloses an energy-saving and exhaust purification device of diesel engine, the technical proposal of which is that a continuous heating device for heating the diesel fuel flowing through the pipeline before the diesel fuel entering the oil injection gun, is arranged in the high pressure oil pipeline between the oil injection gun of diesel engine and the oil pipe joint of the oil injection pump. The heating device is directly connected with the oil injection gun, and the key point is that the heating device is composed of electric heater coil enwound on the heating pipe core and a cross and square communication part used for diesel fuel flowing in the heating pipe core. The utility model is easy to implement, as well the utility model can effectively heat the diesel fuel, enhance the combustion quality of diesel fuel, reduce the harmful gas in coking and exhaust of the combustion chamber of the engine, prolong the service life of the engine, and also solve the problem that the diesel is difficult to start and run in winter with low temperature.

Description

The energy-conservation exhaust gas cleaner of diesel engine

The utility model 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 the purpose of black smoke effect in energy-conservation and the elimination tail gas.

The firing effect of diesel engine not only is related to the power of diesel engine, also has 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 often because of the microthermal climate environment, starts the operation difficulty; Be that the driver feels one of problem of being tired of in brain.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, wasted the energy.Original applying number is " 94211006.4 and 99215880.X ", all be to the high-pressure oil passage of oil atomizer gun Electric heating appliance to be set at diesel injection pump, diesel oil is preheated processing, it is slow that the former exists the heat transfer of electric heating wire generation, thermal loss is big, and working life is short.The latter is communicated with fuel oil because of electric heating wire, and the sealing in the high-pressure oil passage causes very big difficulty to production and processing, unfavorable factors such as cost height.The designer is through for many years experiment repeatedly, and in conjunction with the physical layout of the mounting point of diesel engine, thinks that also there is the problem of dismounting inconvenience in above-mentioned technology.

It is good, handsome in appearance that the purpose of this utility model provides a kind of heats that can be installed on the existing diesel engine, and install, change all the energy-conservation exhaust gas cleaner of diesel engine easily.

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

The energy-conservation exhaust gas cleaner of a kind of diesel engine, it is that oil atomizer gun in diesel engine is to the pipeline of the high-pressure oil pipe between the oil connection of Injection Pump, diesel oil in the convection current by the road is installed, entering the oil atomizer gun previous crops device of heating continuously, heating equipment directly is connected with oil atomizer gun, and key is that heating equipment is by heating the electric heating wire that is wound with on the tube core and being that cross side's shape connectedness that fuel oil is circulated in the heating tube core constitutes.

Further scheme be behind the pad dress mica insulation sheet on the heating tube core again around on electric heating wire, will heat tube core again and pack in the crosswise connectedness, two electrodes of electric heating wire are sealed by resistant to elevated temperatures insulating material again, are fixed in the crosswise connectedness.Connectedness is made the square shape body of available spanner with crosswise connectedness location, saves and set up the hexagon nut position on connectedness, makes the equipment miniaturization easy disassembly.So just make an energy-conservation exhaust gas cleaner of diesel engine, only need two electrodes of handle assembly to be connected on the car accumulator respective electrode, on circuit, add control switch K, connect the Preheating unit power supply during startup earlier, open the oil circuit switch again, the electric heating wire that diesel engine is directly flowed through and generated heat is heated rapidly, is sprayed in the cylinder by oil atomizer gun again.Like this, diesel oil obtains the heating of electric heating wire tube core, and the oil temperature that raises expands fuel oil, for its burning preferably in cylinder provides the foundation.

The utility model has the advantages that: because the fuel oil in the heating tube core of flowing through is earlier through just entering oil atomizer gun after the heating of the electric heating wire on the tube core, improved the effect of preheating diesel oil greatly, electric heating wire and cross side's shape connectedness inner chamber on the heating tube core are sealed by high-temperature insulation material, isolated with air, thus the insulation insulating effect formed.Guaranteed safe in utilization, the working life that has prolonged electric heating wire.

Fig. 3, cross side's shape connectedness shape and structural representation;

Fig. 4, the utility model position in pipeline road reaches the Placement schematic representation with adjacent parts.

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 cross side's shape connectedness 4 of heating tube core 7 and installation heating tube core.The two ends of cross side's shape connectedness respectively have one

section inipple

3,6 to join with high-pressure oil pipe 13 and oil atomizer gun 10 respectively and are communicated with.The center of cross side's shape connectedness is a cavity 2 that can hold to heat tube core, and cavity is communicated as one with the inner chamber of the joint at two ends.Heating tube core 7 is installed in the joint inner chamber at two ends, and two joints are the gateway of pipeline road, and the diesel oil in the pipeline road must enter in the oil atomizer gun after the heating pipe heating again, makes diesel oil and heating tube core contact heating in the pipeline.

With reference to Fig. 2, two

joints

3,6 of cross side's shape connectedness 4 are shaped on screw thread, so that be communicated with and be connected with oil pipe 14 with high-pressure oil pipe 13 with oil atomizer gun 10, the sealing of assurance pipeline road and unimpeded.With reference to Fig. 3, heating tube core 7 dress pads are gone up insulating concrete mica plate 8, and make the part of two electrodes be in mouth of pipe place behind last electric heating wire 9; So that join, put spaghetti from the outer end of electrode 1,5 again and safe and reliable with 12 the two poles of the earth of the storage battery on the automobile.

With reference to Fig. 4, a joint 3 of Preheating unit is screwed in the filler opening of oil atomizer gun 10, again another joint 6 is connected with high-pressure oil pipe 13, two electrodes 1,5 of heating tube core join with 12 the two poles of the earth of the storage battery on the automobile, power control switch 11 on the circuit is that K switch is installed in the operator cabin, with easy-to-operat.
