GLOBAL DIESEL ENGINE CATALYST MARKET
The earliest diesel catalysts were simple oxidation catalysts designed for CO and HC conversion and were developed in the 1970s for underground mining applications. These catalysts subsequently developed into different specialised diesel oxidation catalysts, such as those used to reduce PM emissions in the 1990s. SCR catalysts and NOx adsorber catalysts are two catalyst technologies that have been developed to reduce diesel NOx emissions.
Catalysts for emission control were originally used in spark-ignited gasoline engines. TWC technology, which was introduced in the 1980s, became an essential component of the stoichiometric spark-ignited engine. The TWC catalyst, which works on the basis of non-selective catalytic reduction of NOx by CO and HC, necessitates that the engine be run at a nearly stoichiometric air-to-fuel (A/F) ratio. The diesel oxidation catalyst (DOC) is named for its capacity to accelerate the oxidation of exhaust gas components by oxygen, which is abundant in diesel exhaust.
Carbon monoxide (CO), gas phase hydrocarbons (HC), the organic portion of diesel particles (OF), and non-regulated pollutants such as aldehydes or PAHs can be oxidised to innocuous compounds and therefore controlled utilising the DOC when passed over an oxidation catalyst. An essential function of the DOC in modern diesel aftertreatment systems is to oxidise nitric oxide (NO) to nitrogen dioxide (NO2) as a gas required to maintain the operation of diesel particle filters and SCR catalysts used for NOx reduction.

|1||A study by the UPV/EHU-University of the Basque Country is proposing perovskites to combat the problems surrounding diesel engine emissions||perovskites are a priori emerging as a good way of reducing the cost and prolonging the service life of catalytic converters based on noble metals, such as platinum, palladium, or rhodium. The main drawback of these noble metals is that they are very expensive and also have low thermal stability. So if we can partly replace these metals by perovskites, we will be able to cut the cost of the system and extend its service life.||Global||This would enhance better Adoption and better technologies harnessing.|
GLOBAL DIESEL ENGINE CATALYST MARKET DYNAMICS
DOC is an outstanding example of a pollution control device that may be used to modify or retrofit (add) a diesel engine in order to reduce emissions. Diesel oxidation catalysts are classified into two types: two-way catalytic converters and three-way catalytic converters. The usage of a diesel oxidation device or technology may be found in almost all vehicles powered by diesel engines, including passenger diesel cars, urban transit buses, heavy duty trucks, and off-highway equipment. The diesel oxidation catalyst market is used in the construction, mining, material handling or logistics industries, power generating, maritime & utilities, locomotives, and other industries.
The adoption of tight and stringent emission regulations throughout the world is a significant driver for the diesel oxidation catalyst industry. Another driver for the diesel oxidation catalyst market is the increased use of diesel cars. Because a diesel engine gets greater mileage than a gasoline engine, it is more cost effective. As a result, diesel engines are used for large-scale transportation of products or people. The diesel oxidation catalyst installed in the engines of these cars is expected to aid in meeting the set emission limits.
Diesel engines have gained popularity over gasoline engines over the previous decade due to their greater fuel efficiency, dependability, and longevity, which has been accompanied by a favourable fuel tax position in numerous nations. At the moment, diesel engines power around 60% of all new European automobiles. Catalytic converters were originally used in spark-ignited gasoline engines. A diesel engine catalyst (DOC) is an aftertreatment component that converts carbon monoxide (CO) and hydrocarbons to carbon dioxide (CO2) and water.

RECENT TECHNOLOGICAL TRENDS IN GLOBAL DIESEL ENGINE CATALYST MARKET
Early diesel oxidation catalyst (DOC) formulations were designed with a high removal efficiency of gas phase pollutants such as carbon monoxide and hydrocarbons in mind. Carbon monoxide and hydrocarbon emissions from diesel engines were many times greater when they were first introduced in the 1970s than they are now. The early diesel catalysts were employed in tight spaces, such as underground mining, where air quality was crucial. The use of fuels with lower sulphur content (500 ppm S) enabled the DOC to achieve minor to moderate reductions in PM emissions.
The most recent technology has been the SCR Technology for the Diesel Engines of various commercial and industrial applications. Selective Catalytic Reduction (SCR) is a sophisticated active emissions control technology system that injects a liquid-reductant agent into the exhaust stream of a diesel engine via a specific catalyst. Typically, the reductant source is automotive-grade urea, also known as Diesel Exhaust Fluid (DEF). It is dubbed “selective” because it decreases NOx levels inside a catalyst system by utilising ammonia as a reductant. The chemical reaction is known as “reduction,” and the DEF functions as the reducing agent, reacting with NOx to turn the pollutants into nitrogen, water, and trace quantities of CO2. In the exhaust stream, the DEF can be quickly degraded to create oxidising ammonia. SCR technology alone may reduce NOx emissions by up to 90%.
The DEF initiates a chemical reaction that transforms nitrogen oxides into nitrogen, water, and trace quantities of carbon dioxide (CO2), all of which are naturally present in the air we breathe and are subsequently ejected via the vehicle exhaust. SCR technology is intended to allow nitrogen oxide (NOx) reduction processes to occur in an oxidising environment.
Tires are the heart and soul to operational mechanism of the EV at all times throughout its life that contributes to being the least expensive conglomerate part onboard the vehicle. The EVs tyres need to be technologically advanced and better modified through various requirements being fulfilled at all times. the additional weight of any batteries and electric motor is offset by increasing the load-bearing capacity of the tire carcass, as indicated on most tires by an XL symbol on the sidewall. Energy losses due to tires are of particular concern to EV manufacturers. With rolling resistance accounting for up to 20% of a vehicle’s energy consumption.
Nett Technologies Inc is part of the much-required development and research of the DOC and other catalyst for the diesel-based engines being used in vehicles, commercial and industrial segment of operations. It has most recently produced the M Series Metallic DOC equipment within the market. It falls under the Metallic DOC technology with the M-Series DOC being ideal for Off-road application (construction, mining, material handling, utility), On-road, Power Generation, Marine, Gantry Cranes and Locomotive industries. The Mufflers are built entirely from corrosion resistant materials: aluminized and stainless steels. The DOC Catalytic Mufflers match or surpass the original muffler in sound attenuation and back pressure characteristics with addition of superior emissions performance.
JGC is one of the large-scale producers of the diesel engine catalysts in the market. JGC C&C has developed many kinds of diesel HDS catalysts since the 1990’s. The requirement for HDS catalyst became high and widespread. The catalyst activity for diesel HDS has escalated in the past 15 years to correspond with the strictness of fuel regulations. CDS-LS110 and Altimate-L1 are dramatically improved HDS activity for sulphur free diesel production.
