Background technology
Caused unwanted combustion accessory substance is nitrogen oxides (NOx) and deposited in the form of cigarette ash or ash in diesel engine
Various solid particles, also referred to as particulate matter (or PM).According to various factors, such as fuel mass, operating parameter, start
Hydro carbons caused by machine type and technical conditions, the imperfect combustion from diesel fuel is in the form of PM or other emission bags
Include nitrogen oxides, NO and NO2.Otto engine emission is partially combusted fuel with HC and CO and nitrogen oxides
(NOx) form discharge.Due to the invention of internal combustion engine and the use of a large amount of oil-based fuels, its composition is improved, advanced hair
Motivation design reaches the limit of thermodynamics development.For the complex electronic equipment of fuel injection control, miniaturization technology provides non-
Often low fuel consumption and reduce unburned hydrocarbon and PM, but increase NOx discharges.During this time,
The application of the present invention, reducing pollutant effulent turns into the very important problem of global scale.
The technology of actual use for reducing NOx emission is mainly after-combustion processing, and traditional way is typically to increase
Running cost or fuel consumption.Water injection system is a kind of ancient and reliable noxious emission system reduced in internal combustion engine,
Pre-burning processing is acted on, particularly there is significant effect on NOx emission is reduced.Since World War II to today,
Many successfully actual life applications, such as after-market or original equipment manufacturer's device credentials, are sprayed with thin Sprayable
A small amount of water can improve the fuel efficiency of internal combustion engine and the discharge of tail gas.
Must be relatively small according to the water to the various researchs of Otto engine and actual test, injection, but i.e.
Make in the case where injecting big yield, diesel engine also can normal operation.Diesel engine manufacturers Daimler is run quickly, Wa Xi
Blue and Mitsubishi uses layered fuel-water-fuel injection system, and significant effect is obtained in terms of PM and NOx emission is reduced.In naval
In, even with salt solution.Water in the market automotive system is by the water addition of demineraliting or without addition alcohol
Combination.
Sum it up, such as automobile is arranged on, the diesel oil on the machine of fixed equipment (such as generator, crane, pump etc.)
The successful implementation of any flood pattern of engine meets ability claimed below depending on system：Part dimension is relatively small,
Can have what fast-changing engine loading was reacted immediately easily below hood or in automobile body
Ability, the ability of conventional drinking water can be used；In order that drinking water safety, using chemicals, (particularly chlorination is closed for developed country
Thing) handle and disinfectant, but these additives should not have any possible health risk.In total dissolved solidss (TDS) side
Face, in the U.S., Bureau for Environmental Protection (EPA) suggests not using the water containing the TDS for having more than 500/1000000ths (ppm).Averagely originally
Water contains about 350ppm TDS, although much for municipal or local water supply.These chemicals are for this hair
Bright is important, because once being handled by electrolytic cell, can become powerful water base oxidant so that the consumer goods can bear model
In enclosing.Under varying environment condition (such as -30 DEG C to+40 DEG C), even if flood pattern fails, the energy run completely is still kept
Power.
It it is known that the electrolysis of saline solution produces hypochlorite, and be also disclosed in first patent document, still
Their applications all not in automotive field.
