Not Your Father's Diesel - 50% of European Cars are diesel - Hannah Elliot
For now, Europe leads the world in diesel prevalence. About 50% of the vehicles in Europe have diesel engines, according to the European Automobile Manufacturers Association. Belgium, Luxembourg and France are the most diesel-friendly countries in Europe these days, with a near-80% penetration. Diesels in Europe registered their highest levels in Europe in 2007, up 40% over their level in 1990. Part of the reason for that rapid growth is fuel-tax differentiation that favored diesel fuel. Europeans have also solidified diesel's place in their driving culture at large.Engines that run on diesel fuel use combustion to produce power, but they lack spark plugs, compress air at twice the compression ratio as a gas engine and send fuel directly into the combustion chamber, rather than using a throttle to regulate airflow.
