Aren diesel cars noisy and don they produce heavy emissions?
The first diesel cars were indeed noisy and did produce heavy emissions. However, that is changing rapidly. The new generation of advanced diesel engines are a remarkable improvement over the older generation of diesel engines that most Canadians remember. Thanks to new after-exhaust treatment systems, modern diesels tend to be quiet and produce very few emissions. As with gasoline vehicles, modern diesel vehicles sold in Canada must meet stringent emission standards. Diesel vehicles can offer several advantages over gasoline engines. They are typically more fuel-efficient and as a result, greenhouse gas levels are lower – this means that they are better from a climate change perspective. However, nitrogen oxide and particulate emissions are usually higher for diesel vehicles, which can have a significant impact on health and the environment. On the other hand, gasoline vehicles tend to be less efficient, emitting more carbon dioxide, carbon monoxide and hydrocarbons from their tailpip
