The negative wiring 16 is connected from the negative terminal 1b of the battery 1 to the vehicle body 20 made of iron. The various electrical devices 13 and the minus side of the generator 2 are connected to the vehicle body 20 by wires 17 and 18, and the engine body 3 and the vehicle body 20 are connected by wires 19. This is a so-called body earth configuration in which 20 is used as a negative side common body.

[0003]

By the way, in the conventional automobile diesel engine as described above, the minus wires 16, 17, 18, 19 and the like are screwed to the vehicle body 20 with stat screws (not shown). Because the contact resistance of the screwed part is large, back electromotive force due to the potential difference between the vehicle connection points and electric corrosion of the stud screw connection part occur, and it is said that various electrical components can not exert their performance sufficiently. There's a problem. In addition, a large amount of static electricity S is generated in the intake / exhaust system. However, due to the increase in the contact resistance, the static electricity is not discharged but is accumulated, so that the combustion efficiency is reduced, the engine output is reduced, and defective exhaust gas is generated. Had become.

A lot of static electricity is generated and accumulated in the vicinity, and a back electromotive force is generated due to a diode effect phenomenon. Such a phenomenon has caused a fuel component separation phenomenon, and the mixing ratio of fuel and air has become non-uniform, leading to a reduction in combustion efficiency and the generation of defective exhaust gas. On the other hand, exhaust pipe 1
Although a lot of static electricity S is generated by the flow of exhaust gas in 1,
Such static electricity is also accumulated without being discharged, and static electricity is generated and accumulated in the vicinity of the exhaust pipe 11. Such static electricity similarly causes a component separation phenomenon of exhaust gas, and carbon dioxide (CO 2), hydrocarbon ( A large amount of HC), SPM fine particles and the like are emitted, and there is a strong demand for improvement of exhaust gas components of such diesel engines.

On the other hand, for diesel engines, a method of attaching a special filter to an exhaust pipe to decompose and remove exhaust gas has been carried out. However, the installation cost is high and the filter needs to be replaced once a year. Furthermore, there is a problem that it is difficult to dispose of used filters, and there is a need for a low-cost and highly-sustainable measure for improving exhaust gas components.

The phenomenon of separation of fuel components is suppressed, and the combustion efficiency is improved. In addition, each of the wiring members 65 (65a to 65a)
c), when a current flows, a magnetic field is continuously generated around the wiring member.
a ′ to 7d ′ (especially the fuel immediately before being injected into the fuel injection nozzles 8a ′ to 8d ′), thereby improving the combustion efficiency and improving the poor exhaust gas component ( For example, generation of nitrogen oxides or the like is suppressed.

On the other hand, static electricity generated in the vicinity of the exhaust pipe 11 'and the connection pipe 11a' is also discharged through the wiring members 68 and 69 having low resistance, so that CO, CO2,
Generation of defective components such as HC, SPM fine particles, and nitrogen oxides can be suppressed. In addition, since the wiring members 67 and 68 are connected to the inlet hose 10d 'and the connection pipe 11a' of the exhaust pipe 11 'via the metal ring 57, the wiring members 67 and 68 are connected to each other.
The current flowing through 68 and the like also flows through the ring 57, and a magnetic field is also generated around the ring, and the magnetic field (lines of magnetic force) acts on air in the hose 10d 'and exhaust gas components in the connection pipe 11a'. In addition, the combustion efficiency of the engine is improved, and the generation of each of the above-mentioned defective components and nitrogen oxides (Nox) is suppressed. In addition, the fuel efficiency is improved by improving the combustion efficiency, and the vibration of the diesel engine is suppressed. That is, it was recognized that the effects of the present invention can be obtained by electrically connecting the fuel pipe, the generator, the intake system member, the exhaust system member, and the like to the fuel injection nozzle of the diesel engine with the wiring material.

As described above, according to the present invention, the negative terminal 1b of the battery 1 and the components of each system are connected by a highly conductive wiring material, thereby generating the fuel system and the input / exhaust system of the diesel engine. Back electromotive force and static electricity can be effectively removed, and the magnetic field continuously generated along the wiring material during operation of the engine acts on the intake air, fuel components and exhaust gas, so that the combustion efficiency etc. Can be improved, whereby the exhaust gas component can be improved.

Further, by performing the above-described wiring processing, the potential balance of each component can be balanced, and not only the exhaust gas can be improved, but also the combustion efficiency, the fuel consumption rate, and the efficiency of each device can be improved. The operation response can be improved, the low-medium speed torque of the engine, and the output can be improved.

Further, for example, even if the wiring material is damaged and the effect of the wiring processing is reduced, the performance of the engine is simply restored to the original performance, so that the safety is high, and the connection can be easily repaired only by returning the connection at the damaged portion. Therefore, the improvement of the exhaust gas component of the diesel engine can be realized at low cost.

Furthermore, since the action of the magnetic field generated by the current flowing through the wiring member is also used, a plurality of necessary parts such as a fuel pipe and an intake / exhaust system are required as compared with the conventional method of mounting a magnet at one place. By performing wiring processing, magnetic fields can be easily generated at a plurality of necessary locations, and a plurality of mounting positions can be easily selected in accordance with the characteristics of the engine to be subjected to the wiring processing. In the conventional magnets and the like, the effect disappears in a short time due to the influence of heat. However, in the wiring processing method of the present invention, the effect of heat is small, and the effect is continuously generated by the current flowing through the wiring material during the operation of the engine. Since the magnetic field lines are used, the effect can be maintained for a long time.

The wiring processing shown in FIG. 1, FIG. 2 or FIG. 6 and FIG. 7 of the present invention is merely an embodiment, and is not limited to such wiring processing. Therefore, if the wiring processing brings the effect of the present invention,
A part of the wiring processing shown in FIGS. 1 and 2 and the like may be omitted, or the wiring processing may be further added.

Further, the method for wiring an engine according to the present invention is not limited to a diesel engine for an automobile, but may be used as a generator for a vehicle, a heavy equipment for construction, a ship, a generator for a ship, a stationary generator, or the like. The present invention is also applicable to an engine, and is not limited to an automobile engine.
