Problems solved by technology

Although there are many categories of automotive fuel economizers, fuel additives, etc., most of them have no obvious effect, and some even damage the engine or cause secondary pollution.
Traditional emission reduction technologies, such as exhaust gas purifiers using precious metals such as Pd and Pt, are difficult to be widely used on a large scale due to reasons such as high price, easy poisoning, and resources.
Especially under high power and high fuel consumption operating conditions, such as heavy load, acceleration, climbing or rough roads, the existing fuel-saving and emission-reducing devices are often more difficult to show the effect

Embodiment 1

[0032] The outer shell of the fuel saver is PVC pipe with an outer diameter of Φ 0 =25.4m, length l 0 =250mm. Use BFe10-1-1 iron cupronickel for multi-slot alloy column Bar processing and production, outer diameter Φ 3 =9.9mm, length l 2 =20mm; the porous alloy sheet is made of a plate with a thickness of δ=2.0mm, and the outer diameter is Φ 2 =19.9mm, the number of alloy sheets n=3, the outer diameter Φ 2 =19.9mm, hole diameter ф=1mm, number of holes per sheet m=60; DC motor power w=50 watts.

[0033] According to the fuel consumption and emission test data of the diesel engine van with and without the fuel economizer on the fixed 78km road section around the city for many times, it is calculated that the fuel saving rate is 6% and the emission reduction rate is 31%.

Embodiment 2

[0035] The shell of the fuel saver is a copper tube with an outer diameter of Φ 0 =60mm, length l 0 =350mm, using BFe10-1-1 iron-nickel copper, for multi-slot alloy column Bar processing and production, outer diameter Φ 3 =43.9mm, length l 2 = 40mm; the porous alloy sheet is made of a plate with a thickness δ = 2.0mm, and the outer diameter is Φ 2 =53.9mm, number of alloy sheets n=9, hole diameter ф=1mm, number of holes per sheet m=400; DC motor w=100 watts.

[0036] According to the fuel consumption and emission test results of the diesel engine bus with and without the fuel economizer on the fixed 78km road section around the city, it is calculated that the fuel saving rate is 9.5%, and the emission reduction rate is 35%.

Embodiment 3

[0038] The outer shell of the oil saver is 304 stainless steel pipe with an outer diameter of Φ 0 =100mm, length l 0 =600mm, use BFe30-1-1 iron-nickel copper, for multi-slot alloy column Bar processing and production, outer diameter Φ 3 =81.9mm, length l 2 =50mm; the porous alloy sheet is made of plate with thickness δ=2.0mm, outer diameter Φ 2 =91.9mm, number of alloy sheets n=16, hole diameter ф=1mm, number of holes per sheet m=180; DC motor w=150 watts.

[0039] According to the fuel consumption and emission test data of mining trucks with and without fuel economizers traveling back and forth on a 28km mountainous road section, it is calculated that the fuel saving rate is 9.5%, and the emission reduction rate is 37%.

Abstract

The invention relates to a fuel saving and emission reducing machine applied to a diesel engine. The fuel saving and emission reducing machine comprises a cylindrical shell. A fuel inlet end cover and a fuel outlet end cover are respectively mounted at the front end and the rear end of the shell, a direct-current motor with a fuel inlet is arranged in a one-third cavity of the shell, the one-third cavity of the shell is close to the fuel inlet end cover, a multi-groove alloy column is fixedly arranged on a motor shaft of a rotor of the direct-current motor, a plurality of grooves are uniformly formed in the surface of the multi-groove alloy column, rollers are arranged in the grooves, a fuel outlet is formed in the fuel outlet end cover, a plurality of porous alloy sheets which are perpendicular to the axial direction of the shell and are uniformly separated from one another are arranged in a two-thirds cavity of the shell, the two-thirds cavity of the shell is close to the fuel outlet end cover, spacer sleeves are arranged among the porous alloy sheets, and a plurality of circular holes are uniformly formed in the porous alloy sheets. The fuel saving and emission reducing machine has the advantages that the fuel saving and emission reducing machine can be used for a long term and is simple in structure, convenient to mount, low in cost and ultra-long in service life, maintenance can be basically omitted, and the like.

Description

technical field [0001] The invention belongs to the technical field of fuel saving and emission reduction for diesel vehicles, and in particular relates to a fuel saving and emission reduction device applied to diesel engines. Background technique [0002] The annual sales volume of automobiles (including diesel vehicles) in my country has exceeded 20 million, ranking first in the world for three consecutive years. In 2012, the dependence on foreign oil has reached 56%, and the rapid increase of motor vehicles has also become the cause of large-scale haze weather. One, fuel saving and emission reduction has become the focus of attention of the whole society, which is of great significance to my country's energy security and environmental improvement. Although there are many categories of automobile fuel economizers, fuel additives, etc., most of them have no obvious effect, and some even damage the engine or cause secondary pollution. Traditional emission reduction technolog...
