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 device applied to a diesel engine, which comprises a barrel-shaped shell, and the front and rear ends of the shell are respectively equipped with a fuel inlet end cover and a fuel outlet end cover, and the shell rests on the three sides of the fuel inlet end cover. A DC motor with an oil inlet is installed in one part of the cavity. The motor shaft of the DC motor rotor is fixed with a multi-slot alloy column. The surface of the multi-slot alloy column has multiple grooves evenly distributed. There is an oil outlet on the fuel outlet end cover, and a plurality of porous alloy sheets perpendicular to the axial direction of the casing and evenly spaced are arranged in the two-thirds cavity of the casing close to the fuel outlet end cover. In the spacer sleeve, a plurality of circular holes are evenly opened on the porous alloy sheet. The invention can be used for a long time, and has the characteristics of simple structure, convenient installation, low price, long service life and basically no maintenance.

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...
