Ultrafine Emissions

Modern engines maximize efficiency and are also known to reduce carbon dioxide Ultrafine Emissions, especially in case of ones which inject fuel at high pressure. However, they may also release finer polluting particles that are associated with cancer, lung and heart ailments, and Alzheimer’s disease. To know how bad these particles are affecting the environment, many European researchers are analyzing exhaust particles in great detail, thus playing a crucial role in development of cleaner cars.

More Insights into the New Study Regarding Cleanup of Tiny Particles

Tiny particles emitted by combustion engines contain poisonous substances that pollute the atmosphere. They are one of the main sources of poor air quality, which overall causes the premature death of thousands of European citizens every year. This number is estimated to be more than 500000, which is greater than 10 times the number of people who are killed in road accidents. According to Professor Zissis Samaras, an expert in automotive emissions from Aristotle University of Thessaloniki in Greece, particulate pollution could actually be getting worse than before, even though various particulate filters are introduced for different types of engines.

In order to tackle the long term adverse health effects of Ultrafine Emissions, a research project called DownToTen aims to measure automotive exhaust particles up to ten billionths of a meter, or ten nanometers. This could help car manufacturers design engines in future that can emit fewer of the fine particulate pollutants, consequently safeguarding health and protecting the environment. The project is investigating particles directly released by a car’s engine, and as well as their relationship with older particles already in the air. In this case, the older particles go through a process called atmospheric ageing. Atmospheric ageing is when particles have already entered the environment where they can react with different compounds or get attached to various other substances. This action can end up changing their nature.
