Catalytic converter

Recirculation (EGR) devices, and the Catalytic Converter. The EGR valve opens from back pressure from the car 's exhaust and channels it back into the combustion chamber combining the exhaust with intake air, the amount of oxygen in the mixture is reduced and its combustibility is also decreased, which causes fuel to burn at a lower temperature and produces less nitrous oxide (Lampton). In addition to the EGR circuit is the catalytic converter, “the job of the catalytic converter is to convert…

Imagine a reaction between magnesium metal and a dilute acid like hydrochloric acid. The reaction involves collision between magnesium atoms and hydrogen ions. Increasing the number of collisions per second increases the rate of reaction. Catalytic converters use metals like platinum, palladium and rhodium to convert poisonous compounds in vehicle exhausts into less harmful things. For example, a reaction which removes both carbon monoxide and an oxide of nitrogen is: Because the exhaust gases…

to see my fingernails again. She was a familiar face around the shop, given that neighborhood thieves had routinely targeted her car. This time, though, they had gone too far. Someone had crawled underneath the car and cut out the valuable catalytic converter, and she couldn’t afford a replacement. When I looked at her and said, “That’ll be $563,” her face turned pale. She looked like she was about to faint. My time spent as a mechanic started with an accident of my own. I was driving home after…

Colorado gets about 15.9 inches of rainfall per year. Rain used to be one of the best things that could happen in this state, but as humans pollute our world more and more, rain is becoming harmful. Our precious rainfall is becoming more and more acidic, which is causing harm to plants, wildlife, buildings, and humans. This acidic rain is commonly referred to as acid rain and more properly known as acid deposition. This research will thoroughly examine acid rain, it’s causes, the effects on the…

The atomic number of 45 belongs to the element rhodium which is derived from the Greek word Rhodon meaning rose. It was first discovered in 1803 by William Hyde Wollaston, an English chemist. it is known as one of the PGM (platinum-group metals). Canada, Russia and south Africa are one of the top three producers of rhodium as south Africa as main exporter. It is usually found together with other PGMs as ores mined in its reserves. People who love jewelries are often attracted to the rarity of…

formation of acid rain. Catalytic converters, the part of car exhaust systems that breaks down nitrogen gases, form nitrous oxide via their catalytic process. This resulting nitrous oxide is 300 times more powerful than carbon dioxide as a greenhouse gas (EPA). According to the EPA, nitrous oxide composes about 7.2 % of the gases responsible for global warming. Vehicles with catalytic converters created nearly half of that nitrous oxide. HEV still possess a catalytic converter, however, they…

Engines have had emissions control since the 1970s. Emissions controls were first introduced to engines because a growing number of people had difficulty breathing, and many illnesses attributed to the harmful emissions produced by the internal combustion engine. The environment also held noticeable damage in certain areas which resulted in the EPA (Environmental Protection Agency) being created. The regulations are updated every few years by the EPA. Most big industries frown upon the EPA…

abatement we have adsorption systems like: Bio filters, Activated carbon, Flares, Thermal oxidizers, Catalytic converters, Absorption (scrubbing), Vapor recovery systems, Cryogenic condensers.(C.C.Tawari, et,al, 2012). 4.1.4 Other Devices. Acid Gas and SO2 control: This has do with both the dry scrubbers and wet scrubbers as well as flue gas desulfurization. Mercury control: These include electro-Catalytic Oxidation also known as ECO, Sorbent Injection Technology, furan control and K-Fuel…

When buying a vehicle, some people look at the type of fuel it uses and what the cost of the fuel is when they are buying it. Two of the most common fuels are Gasoline and Diesel. This isn't easy since the price at the gas stations keep changing and the way each are used and measured are different. Here are a few things to show some things you can consider. Diesel fuel is denser than gasoline and contains about 11% more energy per volume. Both fuels relatively cost about the same diesel…
