In the modern era, exhaust emissions have become a significant concern, particularly within the automotive industry. Diesel vehicles, known for their robust performance, face scrutiny for their pollutant emissions, such as Nitrogen Oxide (NOx). Fortunately, advancements in technology have presented cutting-edge solutions to tackle this issue. Three key technologies—Exhaust Gas Recirculation (EGR), Positive Crankcase Ventilation (PCV), and Diesel Oxidation Catalyst (DOC)—work synergistically to reduce harmful emissions from diesel trucks. Fuso Trucks in Indonesia have successfully integrated these technologies, showcasing their commitment to environmental sustainability and regulatory compliance. The incorporation of EGR, PCV, and DOC in Fuso Trucks not only helps in significantly lowering NOx emissions but also enhances the overall performance and longevity of the vehicles. By utilizing these innovative technologies, Fuso Trucks are leading the way in creating a cleaner and more sustainable future for the transportation industry in Indonesia.
The Trio of Emission-Reducing Technologies
Exhaust Gas Recirculation (EGR)
EGR functions by recirculating a portion of the exhaust gases back into the combustion chamber. This process lowers the combustion temperature, thus suppressing the formation of NOx. EGR is also effective in reducing other harmful emissions, such as particulate matter (PM). However, the implementation of EGR can lead to increased fuel consumption, particulate matter, hydrocarbons (HC), and carbon monoxide (CO) emissions, as well as engine wear. To mitigate these issues, diesel engine manufacturers employ additional technologies, such as reducing lubricating oil consumption, increasing fuel injection pressure, and utilizing higher diesel oxidation catalysts.
Positive Crankcase Ventilation (PCV)
PCV prevents exhaust gases from the crankcase from polluting the atmosphere. These gases, rich in oil vapor and hydrocarbons, are routed back to the intake manifold, where they are burned in the combustion chamber. This system maintains cleanliness and pressure in the engine room, extending the life of engine oil and reducing the likelihood of oil leaks. PCV is crucial in preventing the formation of sludge by removing water vapor and combustion residue from the engine room.
Diesel Oxidation Catalyst (DOC)
DOC plays a vital role in converting NOx into more environmentally friendly gases, such as nitrogen and oxygen. It is particularly effective at higher engine operating temperatures and also helps reduce hydrocarbon and CO emissions. DOC consists of a honeycomb structure coated with precious metals, housed in a stainless steel container. As hot exhaust gases flow through the structure, a chemical reaction converts pollutants into less harmful components.
Impact on Fuso Trucks
The integration of EGR, PCV, and DOC in Fuso trucks not only benefits the environment but also enhances engine performance and longevity. These technologies help Fuso trucks meet stringent Euro 4 emission standards, ensuring compliance with regulations in Europe and Indonesia. Fuso’s commitment to reducing emissions is exemplified by their adoption of these technologies in the Canter and Fighter X trucks, equipped with Common Rail technology to maximize engine power and efficiency.
eCanter: The Future of Sustainable Trucking
Mitsubishi Fuso’s revolutionary all-electric truck, the eCanter, offers significant benefits for both business owners and the environment. The eCanter produces zero exhaust emissions, helping to reduce air pollution and support government efforts to improve urban air quality. Additionally, the eCanter delivers substantial operational cost savings, up to 40% more efficient than conventional diesel trucks. With fewer moving parts, maintenance and upkeep costs are lower. The eCanter is also equipped with advanced safety features, such as the Electronic Stability Program (ESP), Lane Departure Warning System (LDWS), Acoustic Vehicle Alert System (AVAS), Intelligent Headlight Control (IHC), and a rearview mirror integrated with a rear camera.
