What does low urea level in diesel vehicles mean?

Low urea level in diesel vehicles means that urea solution needs to be added. The following is an introduction to urea solution for diesel vehicles: 1. Function: The function of urea solution in diesel vehicles is to reduce nitrogen oxides in vehicle exhaust, lower emission pollution, and improve the environmental friendliness of the vehicle. 2. Application: Urea solution is mainly used in cars, trucks, buses, and heavy-duty non-road diesel engine vehicles equipped with SCR exhaust treatment systems. The main harmful substances in diesel vehicle exhaust are nitrogen oxides and particulates, which are reduced inside the engine through technical means. 3. Redox reaction: Diesel engines use selective catalytic reduction technology, where engine exhaust is discharged from the turbine into the exhaust pipe and first passes through a catalytic converter. The urea nozzle on the exhaust pipe sprays urea aqueous solution under the control of the computer. The urea aqueous solution and nitrogen oxides in the exhaust undergo a redox reaction in the SCR catalytic converter, converting the exhaust into nitrogen and water before being discharged.

Why Does the Accelerator and Brake Make a Clicking Noise?

Here are the reasons why the accelerator and brake make a clicking noise: 1. New car: The brake discs and pads are relatively new, so they need to be worn in. The brakes may produce abnormal noises, which can be divided into vibration friction and sharp hissing sounds. However, these noises will disappear after a few hundred kilometers. 2. During sandstorms or dusty weather: Sand or dust particles may enter between the discs and pads, causing a hissing noise from the brakes. 3. The brake pads are worn to the wear zone. There are hard spots as a warning, which produce a hissing sound. If the hissing sound persists for several days every time you brake, and it becomes louder and more frequent, it indicates that the brake pads are worn out. Brake pads usually have some hard metal debris at the bottom. When these debris are ground, they produce a hissing sound of metal friction, signaling the owner that the brake pads are worn out and need to be replaced. 4. A clicking noise occurs during emergency braking, and the brake pedal feels vibrating: This is the ABS (Anti-lock Braking System) function kicking in during emergency braking. In this case, no action is needed.

What is the fuel consumption of the Lavida 1.5?

The manual transmission model has a fuel consumption of approximately 6.5 liters per 100 kilometers, while the automatic transmission model consumes about 7.0 liters per 100 kilometers. Here are three methods to reduce fuel consumption: 1. Control your speed: The most fuel-efficient speed is when the car is in direct drive or overdrive. Driving at different speeds on the same road results in different fuel consumption, so it's best to drive at a moderate speed in direct drive or high gear to save fuel. 2. Gear selection: The choice of gear and shifting actions significantly impact fuel consumption. When starting, select the appropriate gear based on the load and road conditions. If you feel a lack of power while driving, downshift promptly instead of just pressing the accelerator, as excessive throttle use increases fuel consumption. 3. Engine temperature: The engine's temperature directly affects fuel efficiency. Both excessively high and low temperatures lead to increased fuel consumption. The engine's operating water temperature should be maintained between 80°C and 90°C. In cold conditions, preheat the engine before starting, as warming up the engine helps save fuel.
