Abstract

The utility model discloses an energy-saving tail gas purifying device for a diesel engine. A diesel engine fuel preheating device is arranged on the outer wall of a high-pressure oil pipe of the diesel engine, and the energy-saving tail gas purifying device is provided with a device which is used for continuously heating diesel flowing through the pipeline. The energy-saving tail gas purifying device is characterized in that an electric heating wire is mounted on a mica plate, and a pipe core is disposed in a metal shell so as to form the heating device. The energy-saving tail gas purifying device for the diesel engine is easy to be implemented, can effectively heat the diesel, improves combustion quality of the diesel, saves energy, purifies tail gas, and also solves the problem that the diesel engine is started and runs difficultly at low temperature in winter.

Description

The energy-conservation exhaust gas cleaner of diesel engine

Technical field:

The utility model belongs to a kind of device that is used in diesel engine preheating fuel oil, to reach the utilization ratio that improves fuel oil, realizes purpose energy-conservation and the elimination black smoke.

Background technique

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.Often because of the microthermal climate environment, start the operation difficulty and be one of problem that the driver feels put about.The reasons for the above problems are that the fuel oil before the entering DENG firing chamber is in the cold oil state always, inject in the cylinder through oil atomizer gun and can reduce chamber temperature, have influenced 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.

Original applying number is provided with Electric heating appliance for " 99215880X and 022065547 " in the high-pressure oil passage of diesel injection pump to oil atomizer gun; Diesel oil is preheated processing; The former is communicated with fuel oil because of electric heating wire, and the sealing technique problem in the high-pressure oil passage is given processing, produced and cause difficulty.The latter also because of being connected between oil atomizer gun and the high-pressure oil pipe, when Electric heating appliance is installed, make the two separation, also will be with the high-pressure oil pipe deformation process.During assembling, impurity can get in the oil atomizer gun, the adverse consequences that causes oil circuit to block.

Summary of the invention

The technical problem that the utility model will solve; It is deficiency to above-mentioned technology; Particularly little at the motor assembly space; And under the prerequisite of mounting or dismounting difficulty, provide a kind of need not to dismantle the high-pressure oil pipe that oil atomizer gun connects, on the outer tube wall of high-pressure oil pipe, make the electric heater of heating continuously but install one.

Concrete scheme is following:

A kind of diesel engine fuel oil Preheating unit; Be that the diesel oil of on the outer tube wall of the high-pressure oil pipe of DENG, installing in the convection current is by the road getting into the continuous heating equipment of oil atomizer gun previous crops; Heating equipment directly contacts with the high-pressure oil pipe outer tube wall; It is characterized in that heating equipment by installing around electric heating wire on the sheet mica and placing the metal shell body to constitute tube core, has 3 matrix cylindrical bodys in the housing inner chamber.

[0007] key is: heating equipment is by metal shell, cover plate, sheet mica, electric heating wire, wiring terminal, connection lead, fastening Luo Zhu constitute up and down.The housing inner chamber has the concave cylindrical body, and adapts with high-pressure oil pipe.Further scheme is: on the sheet mica of heating equipment, be wound with electric heating wire, wiring terminal and corresponding lead.Lower cover plate is fixed on the electric heating chip on the frame of heating equipment through fastening Luo Zhu, and simultaneously, cover plate is fixed on high-pressure oil pipe in the concave cylindrical body of housing inner chamber through fastening Luo Zhu.Like this, just make a diesel oil preheating device.Only need to be connected to two electrodes of Preheating unit on the electrode of car accumulator; In circuit, add control switch K; During startup, connect the power supply of Preheating unit earlier, diesel oil flows into and is equipped with in the high-pressure oil pipe of Preheating unit simultaneously; After electric heating, spurt in the cylinder, for fuel oil burning preferably in cylinder lays the foundation by oil atomizer gun.

The utility model has the advantages that: the Preheating unit preheating diesel oil, diesel oil is burnt in cylinder preferably, practiced thrift the energy, purified tail gas again, air quality is improved.

Embodiment

Below in conjunction with accompanying drawing,, scheme is specified as an embodiment.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 5, the diesel engine fuel oil Preheating unit mainly by housing 1 and the sheet mica of installing above the frame 7 and the electric heating wire 8 corresponding electric heating wire wiring terminals 6 of coiling, connects lead 5, upper cover plate 2, and lower cover plate 3, fastening Luo Zhu 4,9 constitutes.

The utility model mainly solves from Injection Pump 14 and flows into the high-pressure oil pipe 11 incomplete problem of diesel combustion through oil atomizer gun 10 injection entering cylinders again in view of the deficiency of existing technology.

With reference to Fig. 1, Fig. 2, Fig. 4, Fig. 5, at housing 1 inner chamber the cylindrical body of 3 spills is arranged, diameter is 6mm, matches with high-pressure oil pipe, upper cover plate 2 through fastening Luo Zhu 4, is pressed on high-pressure oil pipe 11 in the cylindrical body of spill.Lower cover plate 3 by fastening Luo Zhu 9, is pressed on the Preheating unit chip on the frame again.

During automobile starting, the power supply from storage battery 13 electricity levels is started working after the Preheating unit energising through K switch 12 closures, and heating high-pressure oil pipe 11 makes oily temperature rise continuously, from oil atomizer gun 10, sprays in cylinder.For burning preferably, diesel oil lays the foundation.

Promptly can be made into the disclosed fuel-firing preheating device of the utility model in a manner described, the energy-conservation of interests DENG arranged, purified tail gas again, air quality is improved.
