National VI diesel vehicles can enter urban areas. Below is relevant information: Automotive Diesel Engines: Automotive diesel engines are categorized by the number of cylinders, including single-cylinder, twin-cylinder, four-cylinder, six-cylinder, eight-cylinder, twelve-cylinder, and multi-cylinder configurations. Decades ago, diesel vehicles were largely abandoned due to their bulky size, high noise levels, and unpleasant odors, leaving a lasting impression in many people's memories. Structure: In terms of structure, diesel engines share a basic framework with gasoline engines, both featuring components such as the cylinder block, cylinder head, piston, valves, connecting rods, crankshaft, camshaft, and flywheel. However, the fundamental difference lies in their operation: diesel engines use compression ignition (diesel), while gasoline engines rely on spark ignition (gasoline). This distinction between 'compression ignition' and 'spark ignition' marks their key divergence.
