Yes, it can. Urea is a liquid used in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. This urea consists of 67.5% deionized water and 32.5% high-purity urea. Without urea, it needs to be replenished promptly. Here is some extended information: The function of automotive urea solution is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, primarily to make vehicles energy-efficient and environmentally friendly, enabling them to meet national emission standards. Therefore, if the urea pump is broken, the exhaust gas content in the tailpipe will increase, polluting the environment, and it should be addressed promptly. When the urea pump fails, the vehicle will directly trigger an SCR fault alarm.

What Precautions Should Be Taken When Driving in the Rain?

When driving in the rain, it's important to pay attention to your speed, among other things. Here are some relevant tips for driving in the rain: 1. Speed: Adjust your speed appropriately according to the intensity of the rain. For example, when driving on mountainous roads during heavy rain, set your windshield wipers to the fastest speed (if they still can't clear the water completely), turn on your hazard lights, reduce your speed (to around 30-40 km/h), drive cautiously, and honk more frequently on curves. 2. Driving: Avoid sudden braking or sharp turns of the steering wheel, as these actions may cause skidding and lead to danger. 3. Parking and waiting: If the rain becomes too heavy, find a safe spot to pull over and wait until the rain lessens or stops. 4. Stay alert and watch for water accumulation: Many drivers encounter hazardous "traps" such as standing water, potholes, or debris on the road during rainy conditions. Besides staying focused, ensure your windshield wipers and defoggers are on to maintain clear visibility through the front and rear windshields for accurate judgment of the road conditions. At night, when visibility decreases further, these "traps" become even more dangerous. Always keep an eye on the road ahead and pass through any hazards at a low speed.

What are the signs of a failing fuel pump?

Signs of a failing fuel pump include sluggish acceleration, difficulty starting the engine, and unusual noises. Below are some common causes of fuel pump failure: 1. Poor fuel quality: When fuel quality is poor, the fuel tank can contain various impurities or foreign particles. The fuel pump draws fuel through a filter screen at its base and delivers it to the engine. During this process, larger particles are blocked by the filter, while smaller particles are sucked into the fuel pump motor, accelerating wear and leading to premature failure. 2. Long overdue replacement of the fuel filter: If the fuel filter is not replaced for an extended period, the fuel supply system can become severely clogged, forcing the fuel pump to work harder and operate under high load conditions.

What are the causes of battery plate sulfation?

Plate sulfation (also known as plate sulfation or irreversible sulfation) refers to the phenomenon where, when a battery remains in a discharged state for an extended period, a layer of coarse-grained white lead sulfate crystals forms on the plate surface. These crystals are hard and difficult to dissolve, making them challenging to participate in oxidation reactions during charging. The main causes of battery plate sulfation are as follows: 1. Excessive discharge or deep discharge with small currents: Frequent excessive discharge or deep discharge with small currents causes lead sulfate to form in the inner pores of the active material, making it difficult to recover during normal charging. 2. Incomplete charging, frequent undercharging, or lack of periodic supplemental charging: Incomplete charging, frequent undercharging, or failure to perform periodic supplemental charging prevents the elimination of coarse crystal grains formed early on the plates. 3. Low electrolyte level during use: A consistently low electrolyte level exposes the upper part of the plates, preventing them from undergoing electrochemical reactions with the electrolyte and hindering full recovery of the active material. 4. Impure electrolyte, excessively high density, or high temperature: Impure electrolyte, excessively high density, or high temperature can also lead to battery sulfation.

Can Temporary License Plates Use ETC?

As long as the ETC is activated, you can use the ETC lane. Since ETC is an automatic toll collection device, it identifies the ETC electronic tag on the vehicle and deducts the balance from the tag, which has little to do with whether a temporary license plate is used. ETC Toll Deduction Principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and by using computer networking technology for backend settlement with banks, the system achieves the purpose of allowing vehicles to pay tolls without stopping at road and bridge toll stations. All of this is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Saves time: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduces wear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improves efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More Policy Support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, intercity transportation smart cards will be basically realized in key city clusters, and the proportion of vehicles equipped with ETC will significantly increase." It also set a clear target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More Future Possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC adoption rate for passenger vehicles, efforts will also be made to promote ETC usage for trucks in the future. There will be exploration into deeper integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-to-infrastructure coordination, providing comprehensive travel services for car owners. This means more application scenarios will support ETC usage. ETC Usage Precautions: The ETC transaction sensing range is 8 meters. When the vehicle in front stops, to prevent issues such as the front vehicle's ETC device malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters to avoid automatic toll deduction for the front vehicle. The recognized speed for ETC lane passage is 20 km/h. Driving too fast may prevent the system from reading the vehicle's device information, leading to toll deduction failure. Unauthorized removal or relocation of the OBU device, or detachment or loosening of the ETC electronic tag, will render the tag invalid. It can be taken to the bank where the ETC card was issued or to a highway service office for inspection. If the detachment or loosening is not due to human error, reactivation is sufficient. When using a debit card linked to ETC, insufficient balance may cause toll deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pay with cash or card. Thick windshields may cause poor signal reception. This is particularly important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

What is the dumbest method for adjusting valves on a 4-cylinder diesel engine?

First, take a 4-cylinder engine with a firing order of 1-3-4-2 as an example. When cylinder one is at the top dead center of compression, valves 1-2-3-6 can be adjusted. When cylinder four is at the top dead center of compression, valves 4-5-7-8 can be adjusted. Then, rotate the crankshaft 360 degrees clockwise to position the piston of cylinder four at the top dead center of the compression stroke. Here are some precautions regarding valve adjustment for diesel engines: 1. Note one: Never overlook the issue of valve clearance. If the valve clearance is too small, it will lead to a decrease in engine power and may even cause the valves to burn out. 2. Note two: Excessive clearance is also not allowed, as it will not only accelerate the wear of components but also affect the intake and exhaust conditions of the cylinders. Therefore, when abnormal clearance is detected, it must be addressed promptly.
