They are less efficient than diesel engines but are quieter and less expensive to manufacture and maintain.
Environmental Impact
Diesel:
-
Diesel fuel has higher energy content, which contributes to better fuel economy.
However, it produces more nitrogen oxides (NOx) and particulate matter, which are harmful to the environment.
-
Gasoline:
Gasoline burns cleaner than diesel but releases more carbon dioxide (CO2), a greenhouse gas that contributes to global warming.
