The Health Effects Institute (HEI) recently released a report saying that the new diesel engine used in automobiles is not as likely to increase lung cancer risk as people usually think.

HEI recently launched an independent investigation to explore whether diesel engines with new technologies have the expected reductions in air quality to improve air quality and whether diesel engines represent higher health risks. As new diesel engines generally use EGR exhaust gas recirculation systems and other devices, the emissions of nitrogen oxides, hydrocarbons and particulate matter are almost reduced to zero, and the negative impact on health is actually not prominent.

The survey focused on heavy truck emissions and measured environmental impacts from a variety of perspectives, including passenger cars, agriculture, construction, fishing and transportation.

Because diesel engines have left many people with impressions of high emissions and increased lung cancer chances in the old days, they are regarded as backward and harmful by some regions. Some people even plan to eliminate diesel engines in the next 10 to 20 years. For example, the UK has proposed It is required to prohibit diesel vehicles from entering the road in 2040.
