How much urea is consumed per 100 liters of diesel?

It depends on fuel consumption, with a normal ratio of 100:5-6. Lanka·Automotive Urea can achieve a ratio of 100:4. The following is an introduction to diesel: 1. Introduction: Diesel is a light petroleum product, a complex hydrocarbon mixture, and the fuel for diesel engines. 2. Composition: Diesel is mainly blended from diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be obtained from shale oil processing and coal liquefaction. 3. Types: Divided into light diesel and heavy diesel, widely used in large vehicles, railway locomotives, and ships.
I did the math a couple of days ago when hauling cargo on the highway: for every 100 liters of diesel, you need about 3-5 liters of urea. This ratio mainly depends on engine technology and road conditions, with China V and VI vehicles generally around 3%. For heavy trucks like ours running long distances, on flat roads, 100 liters of fuel consumes about 3.2 liters of urea, but climbing steep hills can push it up to 5 liters. I remember last winter driving in Northeast China at -20°C, the urea consumption suddenly increased. Later, I found out it was due to slight nozzle clogging causing excessive injection. Now it's become a habit to check the urea tank level every 500 liters of diesel and clean the nozzle promptly if any abnormalities are found. It's much better than suddenly running out of urea on the road and getting speed-limited.
Fellow operators of construction vehicles are well aware that urea consumption is generally linked to diesel usage. The operational records of the loader I operate show a standard ratio of 4 liters of urea per 100 liters of diesel. However, this ratio can fluctuate. For instance, during crushing operations with intense vibrations, urea consumption rises to 5 liters. Conversely, during continuous summer operations with air conditioning, engine temperature affects urea injection efficiency, reducing consumption to 3.5 liters. Last year, using urea solution from a small-scale manufacturer resulted in over 6 liters consumed per 100 liters of diesel. The mechanic attributed this to inaccurate injection caused by impurity blockages. Now, I strictly use automotive-grade urea, scanning the anti-counterfeit code on each barrel, ensuring both peace of mind and cost savings.
Attention for diesel SUV owners: For every 100 liters of diesel consumed, a passenger vehicle typically uses 3-5 liters of urea. Based on my actual measurements, urban stop-and-go traffic consumes 4.7 liters per 100 liters of fuel, while highway cruising only requires 3.3 liters. Once when the malfunction indicator lit up, diagnosis revealed that inferior urea had crystallized and clogged the pipes, causing abnormal consumption to spike to 8 liters. The 4S shop technician advised regularly replacing the OEM urea filter to maintain dosing accuracy. Now I always check urea levels during refueling, keeping the fluid above 1/3 tank.
