Abstrakt: “Global warming” or “climate change” is caused by rising fossil fuel emissions, harming the environment and agriculture. Immediate solutions for sustainable growth are needed. Diesel engines, although efficient and durable, produce more pollutants than gasoline engines and are widely used in power-intensive applications. Reducing these pollutants is essential for environmental and public health, achievable through new technology. The article reviews methods for cleaning diesel exhaust, noting that emission after-treatment devices lose efficiency over time, affecting engine performance. Emphasizing durability, it highlights maintaining high purification standards to meet regulatory and environmental goals. The costs of diesel exhaust purification units vary based on technology complexity, material quality, and application scale. Advanced systems like selective catalytic reduction (SCR) and diesel particulate filters (DPF) require significant investments to ensure efficiency and durability. Installation costs, particularly for retrofitting, can be substantial, and ongoing maintenance and replacement parts add to long-term expenses. Despite these high initial and operational costs, these units are essential for complying with environmental regulations and reducing health risks from diesel emissions. Economic burdens can be alleviated through government incentives and subsidies that promote cleaner technologies.
