Why Do Diesel Vehicles Need Urea?

[LeAlexander]

Diesel vehicles require urea to reduce exhaust emissions and protect the atmospheric environment. Adding urea to diesel vehicles helps convert harmful nitrogen oxides in the exhaust into nitrogen and water, thereby reducing the hazardous components of the emissions. The main components of a diesel engine include: 1. Engine block, consisting of the cylinder block, cylinder liner, cylinder head, cylinder gasket, oil pan, flywheel housing, timing gear housing, and front/rear mounts; 2. Crankshaft connecting rod mechanism, comprising the crankshaft, connecting rod, piston, and piston pin; 3. Valve train, including the timing gear, camshaft, tappet, push rod, and rocker arm; 4. Fuel system, made up of the diesel tank, fuel line, diesel filter, fuel injection pump, and injector; 5. Lubrication system, consisting of the oil pump, oil filter, pressure regulator, pipelines, gauges, and oil cooler.
