DIESEL ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18662226 titled 'DIESEL ENGINE
Simplified Explanation: This patent application describes a diesel engine equipped with an exhaust after-treatment device that includes a Diesel Particulate Filter (DPF) and a Selective Catalytic Reduction (SCR) system. The DPF collects particulate matter from the exhaust gas, while the SCR reduces nitrogen oxides by adding urea. The DPF is positioned on one side of the engine in a direction perpendicular to the engine's front-rear and up-down directions.
Key Features and Innovation:
- Diesel engine with exhaust after-treatment device
- Includes DPF for particulate matter collection and SCR for nitrogen oxide reduction
- DPF positioned on one side of the engine in a specific direction
Potential Applications: The technology can be applied in diesel engines across various industries such as automotive, marine, and power generation.
Problems Solved:
- Reducing harmful emissions from diesel engines
- Improving air quality by purifying exhaust gases
Benefits:
- Lower emissions of particulate matter and nitrogen oxides
- Compliance with environmental regulations
- Enhanced engine performance and efficiency
Commercial Applications: The technology can be utilized in the automotive industry for vehicles that require efficient emission control systems, potentially leading to cleaner transportation and reduced environmental impact.
Prior Art: Readers interested in prior art related to this technology can explore patents and research papers on diesel engine exhaust after-treatment systems, DPFs, and SCR systems.
Frequently Updated Research: Stay informed about the latest advancements in diesel engine exhaust after-treatment technologies, emission control strategies, and sustainable transportation solutions.
Questions about Diesel Engine Exhaust After-Treatment Technology: 1. What are the key components of an exhaust after-treatment system in a diesel engine? 2. How does the addition of urea help reduce nitrogen oxides in the exhaust gas of a diesel engine?
Original Abstract Submitted
A diesel engine is provided with an exhaust after-treatment device for purifying exhaust gas. The exhaust after-treatment device includes a DPF that collects a particulate matter included in the exhaust gas, and an SCR that reduces nitrogen oxides included in the exhaust gas through addition of urea. The DPF is arranged to extend in an engine width direction orthogonal to both the engine front-rear direction and an up-down direction, on one side of the engine front-rear direction with respect to the DPF. The DPF and the SCR are attached to the diesel engine.
