What are the reasons why diesel vehicles do not consume urea?

Diesel vehicles may not consume urea due to reasons such as a damaged urea pump, blocked urea pipelines, or clogged nozzles. The solution is to immediately visit a professional 4S store for inspection and repair. The following are the consequences of diesel vehicles not consuming urea: 1. Environmental pollution: Failure to add urea to diesel vehicles can have extremely adverse effects on the ecological environment, which is also prohibited by national laws and regulations. 2. Reduced power: This is not a direct consequence of not adding urea, but when the engine's electronic control system fails to detect urea injection and exhaust pollution exceeds standards, it will forcibly limit the engine's torque output. 3. Damage to the SCR injection system: If there is no urea for a long time, the nozzles, pipelines, and urea pump in the SCR system may crystallize and clog, or be damaged by high temperatures.

What Causes a Car to Not Shut Off?

The inability to shut off the engine with a push-button start is mainly caused by issues with the push-button start control module. Additionally, it's necessary to check if there is a short circuit in the main relay. You should promptly visit an after-sales service for inspection and troubleshooting. If the car is still under warranty, this can be handled for free. Functions of Push-Button Start: The intelligent system of push-button start includes the following functions: automatic unlocking, automatic locking, automatic window closing, automatic anti-theft, one-button start, one-button shut-off, automatic locking before driving, automatic unlocking when parking and shutting off the engine, and trunk opening. Advantages of Push-Button Start: When the owner approaches the vehicle within about 3 meters, the door locks automatically unlock, disabling the anti-theft system. When the owner leaves the vehicle, the door locks automatically lock and activate the anti-theft system. When the owner enters the vehicle, simply pressing the start button is enough for keyless operation.

What are the disadvantages of not washing a car for a long time?

The disadvantages of not washing a car for a long time are as follows: 1. Damage to the paint: If a car is not washed for a long time, the paint surface will age and deteriorate faster due to erosion and adhesion of acidic components in rainwater and air, as well as harmful substances like bird droppings and dust. Damaged paint can also expose the metal parts of the car body to oxidation, leading to premature damage. 2. Component damage: If a car is not washed for a long time, some sealing strips may not receive timely maintenance, causing them to age and fail, thereby reducing sealing performance. Additional information: When washing a car, it is best to choose mild weather, as cloudy days are not conducive to drying residual water, while sunny days cause the metal panels and paint surface to expand due to heat. Washing the car under such conditions, with the sudden temperature change, can make the paint brittle and prone to cracking. After washing, it is advisable not to drive immediately, as the car is not completely dry, especially in areas like the hood gaps and door rubber seals, which are prone to dust accumulation.

Is It Serious to Smell Burning After Revving the Engine on an Uphill?

Smelling burning after revving the engine on an uphill is likely caused by a clutch issue, as slipping clutch plates can produce a burning odor. Below is a detailed explanation of why revving the engine may result in a burning smell: Reasons for the Burning Smell After Revving the Engine on an Uphill: The burning smell is most likely due to a clutch problem. Manual transmissions transfer power through the friction of clutch plates. When the clutch plates are excessively worn, friction weakens. If the engine outputs too much power, the clutch plates may slip and overheat, producing the burning smell. Correct Clutch Operation Method on an Uphill: When driving uphill, the clutch should be fully released to ensure complete engagement, allowing the car to climb smoothly. Failing to release the clutch can cause the brake pads to slip, leading to vehicle instability. Over time, this not only reduces the clutch's lifespan but also shortens the brake pads' durability. Therefore, always fully release the clutch when climbing a hill.

What are the techniques for braking?

Here are the techniques for braking: 1. Emergency braking: Some vehicles are not equipped with ABS, so it is not recommended to fully press the brake pedal at once. Instead, press the brake pedal twice in succession to prevent wheel lock-up, which could lead to skidding and loss of steering control. 2. Braking in rainy conditions: When driving on wet roads, avoid slamming the brake pedal or turning the steering wheel sharply. After passing through a waterlogged area, it is advisable to gently press the brake pedal twice to utilize inertia and friction to remove water from the brake discs, preventing brake failure during sudden braking. 3. Braking while following another vehicle: The main purpose of braking while following another vehicle is to maintain a safe distance. Therefore, gently press the brake pedal and not only observe the braking of the vehicle in front but also pay attention to the dynamics of the vehicles ahead of it. If you notice the vehicle in front braking, place your foot on the brake pedal in advance to prepare for any sudden braking by the leading vehicle.
