Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water.
-alumina supports along with a small amount of lanthanum oxide can efficiently turn the carbon monoxide in automotive exhaust into carbon dioxide at temperatures as low as 40 ?Celsius, Most of the pollutants from a modern automobile are emitted during the first 30 seconds of starting a car, when the catalyst is still being warmed.
With a new DC/DC converter, the heating discs of the electrically heated EMICAT catalyst ( earlier post ) can now also be supplied with electricity in high-voltage vehicles. EMICAT heated catalyst and the new DC/DC converter. It is already in use in vehicles with a pure combustion engine or in mild hybrids.

Over the past few months, we have converted it to DME together with our partner FPT. In addition, the valves and valve seat inserts were converted to materials suitable for DME. An electrically driven compressor for precise exhaust gas recirculation is also used. This is done via exhaust gas recirculation (EGR).
It then sprays the treated sea-water into the exhaust funnel, where CO 2 is converted into bicarbonates, SO 2 into sulfates and NO x into nitrates through natural chemical processes. The process water is collected, filtered, and pumped into an aft tank for further processing, and eventually returned to the ocean.

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al.
The catalyst removes the gaseous pollutants and now also solids such as particulates from the exhaust gas flow. The well-known three-way conversion catalyst—in use in North America since 1976 and in Europe since 1986—is now capable of removing considerably more than 95% of the undesired substances from the exhaust gas flow.
The new options would reduce some economic and procedural impediments to clean alternative fuel conversions while maintaining environmental safeguards to ensure that acceptable emission levels from converted vehicles are sustained. EPA expects the streamlined approach to result in a cost savings for many converters. Intermediate age.
The demonstration of ClearFlame’s engine technology was implemented by taking a Class 8 diesel truck running on a Cummins X15 500hp 15L heavy-duty engine—commonly used for long-haul truck and off-highway applications—and converting it to run on renewable E98 ethanol.
The high-performance, three-way catalytic (TWC) converter is one of the workhorses of emissions reduction for gasoline engines. This function is crucial in current TWC, in which the oxygen partial pressure in the exhaust must be regulated to be near the ideal air-to-fule ration (A/F = 14.6). —Machida et al.
These clusters are more reactive than the single atoms and, hence, exhaust gases can be much better removed. Among others, they are applied in nearly all combustion processes to reduce pollutant emissions. To convertpollutants, they usually have to react with oxygen in the catalyst. Graphics: Florian Maurer, KIT).
It, or a scaled-up version, could also provide a solution for the Asian motor vehicle fleet, in which two-stroke engine vehicles constitute a major share—and contribute significantly to air pollution. Everything else—pistons, porting and crankcase, bearings, exhaust, etc.—were Lubrication proved to be an issue.
This gasoline reduces gas pollutants emitted from the exhausts of engines manufactured after 2009 by up to 60% for nitrogen oxides (NO x ), 45% for carbon monoxide (CO) and 55% for hydrocarbons (HC). (California, Europe, Japan, South Korea, and several other countries have gasoline sulfur limits of 10 ppm. Earlier post.).
While properly engineered conversion systems can reduce or at least not increase emissions, poorly designed systems can lead to much more pollution. The revised procedures will vary based on the age of the vehicle or engine being converted. Exhaust, Evap, and OBD testing. MY >= current calendar year - 1. Intermediate age.
Exposure to these pollutants was most elevated in the coach located closest to the locomotive: geometric means were 126,000# cm -3 for UFP, 249 μm 2 cm −3 for LDSA, and 17,800 ng m −3 of BC; these concentrations are much higher than those previously reported for other modes of public transportation.
This newly developed ENSs could improve low-temperature automobile exhaust treatment. Meanwhile, hydrocarbons, such as propylene (C 3 H 6 ) and propane (C 3 H 8 ) are typical automobile exhaust gas pollutants and must be converted to carbon dioxide (CO 2 ) and water (H 2 O) before they are released as exhaust.

Ozone (O 3 ) is a dangerous air pollutant that is highly reactive and causes both short- and long-term adverse health effect and also disrupts plant growth. Ozone is formed when nitrogen oxide from exhaust is irradiated with UV light and releases an oxygen atom, which reacts with an oxygen molecule (O 2 ) to form an ozone molecule (O 3 ).
The exhaust manifold is integrated directly in the cylinder head, which reduces the number of parts and overall weight. For maximum efficiency, the three-way catalytic converter is located right at the engine outlet and equipped with two lambda sensors. This system has two advantages. And two, it helps to warm up the cabin faster.
Scientists from Tokyo Metropolitan University have developed a low-temperature catalyst for removing NO x gas from industrial exhaust using ammonia. Nitrogen monoxide (NO) and nitrogen dioxide (NO 2 )—nitrogen oxides (NO x )—are common atmospheric pollutants created by burning fossil fuels, coal and natural gas.
With respect to the emissions updates, the OEMs must also provide proof that the changes do not negatively impact any other parameters relevant for type approval—such as pollutant and CO 2 emissions, fuel consumption, noise and engine power. Excessively high pollution affects air quality in many German cities.

However, SIDI engines also have the potential for increased pollutant formation, and require either careful control of combustion for reduced engine-out emissions, or an exhaust after-treatment systems similar to those under development for diesel vehicles. Lean-burn (i.e., a high air-to-fuel ratio) SIDI (e.g.,
Low pressure EGR (exhaust gas recirculation). Lower pressure EGR (exhaust gas recirculation). The use of EGR cuts emissions by recycling exhaust gases and re-injecting them into the combustion chamber to bring down high combustion temperatures and minimize the production of oxygen, two factors which favour the production of NO x.
Due to their high oxygen concentration, they suppress pollutant formation in combustion. This opens the door for alternative strategies for the engine operation, including new engine concepts and exhaust gas aftertreatment systems.
