From diesel engines in Europe

In the country, to bring diesel engine when we may first think of the mind is the big truck or tractor, the tail may also braved thick smoke. However, if the engine is brought to the Europeans, their minds are likely to emerge out of the first car's image. This difference closely with European automotive history.

Europeans and the diesel engine has deep roots. As early as 70 years ago gave birth to a diesel-powered Mercedes-Benz cars, the efficiency is much higher than that era's other gasoline-powered cars. And the first 1990s, CDI (common rail direct injection system) technology has greatly promoted the birth of the development and spread of diesel cars. The Europeans also have reason to develop the diesel engine. Europe's most dependent on imported fuel, the oil price is relatively higher than other parts of the world. For money considerations, people tend to buy more fuel-efficient diesel vehicles. So basically diesel technology breakthroughs from the European car manufacturer, while in Europe the proportion of diesel cars is the world's highest. European car prices are also directly contributing to global expansion in the global popularity of diesel vehicles. Next, we specifically look at the world's major car market share of diesel.

Half of the cars use diesel in Europe

Europe as the birthplace of diesel engines, diesel car ownership is very high. On the one hand, Europe completely dependent on imports of oil, so oil prices much higher than the average elsewhere in the world, the characteristics of diesel fuel by consumers on identity. On the other hand, European countries pay more attention to the emission standards on carbon dioxide emissions, the greenhouse effect which is the culprit. Carbon dioxide emissions than gasoline and diesel have been granted the support of governments, so the tax rate is lower than European diesel fuel. Because all of these advantages, diesel engines in Europe is very competitive. According to Wikipedia the data, in 2007, nearly 50 percent of new cars sold in Europe use diesel engines. If the SUV and pickup is also taken into account, this proportion will increase at least 10%.

Americans look forward to diesel cars

The United States and Europe the situation is different. On the one hand, the U.S. average price is about twice cheaper than in Europe, so the characteristics of diesel vehicles to save money is not prominent. On the other hand, U.S. emissions standards and unlike Europe, more emphasis on nitrogen oxides, particulate matter control, which is the soft underbelly of the engine. But by the impact of emission standards, diesel fuel tax rate is also higher than that of diesel vehicles to the U.S. economy greatly reduced. The current proportion of U.S. gasoline up to 95% (including SUV, commercial vehicles), many gas stations do not even have diesel pumps. Due to various considerations, the United States-made diesel car prices are usually sold in Europe but not sold in the domestic market. But many Americans are calling their own to have more and more diesel cars appear. An owner on the website in ScientificAmerican question: "Why many European high-performance diesel cars in the U.S. can not buy?" And thread support in most diesel vehicles, and attacked the state government emissions standards obsolete, car prices combined with the oil companies profit , high tax rates on diesel and unfair.

Diesel cars in China and Japan is not popular

Japan and the United States the situation is similar. On the one hand, Japan's low oil prices, diesel fuel economy is not prominent. On the other hand, Japan's emissions regulations are most stringent in the country, diesel cars sold in the country difficult to be granted. The proportion of diesel cars in Japan only about 0.5%, but many Japanese car firms have to produce diesel cars sold in Europe.

Some special situation in China. China's national emission standards in Europe is basically a copy, presumably favor of a European car prices in the domestic mass production and sales of diesel vehicles. But, although the vast majority of commercial vehicles and many SUV diesel, the proportion of diesel cars is very low, about 0.2%, not only far lower than in Europe, also lower than the popularity of diesel vehicles is not yet the United States and Japan . Specific reasons are complex, in later statements.
