napaisip lang bat kaya linagay or bat kaya na imbento pa ang egr kung ang main purpose lang ay bawasan ang NOx...mukahang mas marami pang bad effects lalo na sa diesel

In diesel engines

By feeding the lower oxygen exhaust gas into the intake, diesel EGR systems lower combustion temperature, reducing emissions of NOx. This makes combustion less efficient, compromising economy and power. The normally "dry" intake system of a diesel engine is now subject to fouling from soot, unburned fuel and oil in the EGR bleed, which has little effect on airflow, however, when combined with oil vapour from a PCV system, can cause buildup of sticky tar in the intake manifold and valves. It can also cause problems with components such as swirl flaps, where fitted. Diesel EGR also increases soot production, though this was masked in the US by the simultaneous introduction of diesel particulate filters.[6] EGR systems can also add abrasive contaminants and increase engine oil acidity, which in turn can reduce engine longevity.[7]

Though engine manufacturers have refused to release details of the effect of EGR on fuel economy, the EPA regulations of 2002 that led to the introduction of cooled EGR were associated with a 3% drop in engine efficiency, bucking a trend of a .5% a year increase.[8]

what do you think?
for me mas gugustuhin kupang maglinis ng intake at ng EGR every 20k or 30k km kaysa contribute to the pollution...

bat kaya may mga taong kayang bumili ng napakamahal na sasakyan then ipapa disable nila ang EGR para maiwasan masira ang sasakyan in expense of mother earth, to be specific the air that we breath in?

sa palagay ko lang di natin kaagad napapansin ang epekto ng NOx sa atin pero in the long run may mga taong(malay mo ikaw mismo na nag pa disable ng EGR) magsa suffer parin dito dahil sa mga taong walang pakialam sa mother earth basta wag lang maisra ang sasakyan..ang sasakyan pweding i maintain ng maayos para di masira diba pweding imaintain din si mother earth para di masira?


Health effects ng NOx

NOx reacts with ammonia, moisture, and other compounds to form nitric acid vapor and related particles. Small particles can penetrate deeply into sensitive lung tissue and damage it, causing premature death in extreme cases. Inhalation of such particles may cause or worsen respiratory diseases, such as emphysema or bronchitis, or may also aggravate existing heart disease.[8]

NOx reacts with volatile organic compounds in the presence of sunlight to form Ozone. Ozone can cause adverse effects such as damage to lung tissue and reduction in lung function mostly in susceptible populations (children, elderly, asthmatics). Ozone can be transported by wind currents and cause health impacts far from the original sources. The American Lung Association estimates that nearly 50 percent of United States inhabitants live in counties that are not in ozone compliance.[9]

NOx destroys ozone in the stratosphere.[10] Ozone in the stratosphere absorbs ultraviolet light, which is potentially damaging to life on earth.[11] NOx from combustion sources does not reach the stratosphere; instead, NOx is formed in the stratosphere from photolysis of nitrous oxide.[10]

NOx also readily reacts with common organic chemicals, and even ozone, to form a wide variety of toxic products: nitroarenes, nitrosamines and also the nitrate radical some of which may cause biological mutations. Recently another pathway, via NOx, to ozone has been found that predominantly occurs in coastal areas via formation of nitryl chloride when NOx comes into contact with salt mist.[12]
