Chinese Brand Kinglong Yutong Diesel Engine for Ford Transit Bus

The difference between diesel engine and other internal combustion engines (such as gasoline engine) is that the latter introduces the flammable mixture of air and vaporized or gaseous fuel into the cylinder and ignites it with an electric spark after appropriate compression, while the former does not use an ignition system, so it is often called a compression ignition engine. The fuel for diesel engines is graded and unrefined. Its disadvantages are high initial cost and large weight per horsepower, resulting in air pollution, running noise and vibration.

The diesel engine has better efficiency, so it can reduce carbon dioxide emissions, but the pollution is high (for example, long carbon chain organic compounds are prone to produce suspended particulates (SS) mainly composed of carbon particles after combustion); The use of high quality (ultra-low sulfur) diesel fuel and newer engine and pollution control technologies can reduce a lot of pollution, but until the latest technology can make diesel vehicles meet the environmental standards of the United States.
