Automotive urea is filled into a dedicated urea storage tank, which is located near the fuel tank. Adding urea is specific to diesel engines because diesel engines emit harmful nitrogen oxide (NOx) gases during operation, which are detrimental to the atmosphere and human health. When urea encounters NOx gases emitted by diesel engines, a chemical reaction occurs, converting NOx into harmless nitrogen and water, which are then released. The following provides an introduction to automotive urea: 1. Automotive urea is an essential additive for the SCR (Selective Catalytic Reduction Technology) solution. 2. The SCR system includes a urea tank (containing diesel exhaust fluid) and an SCR catalytic reaction tank. 3. The operation process of the SCR system: When NOx is detected in the exhaust pipe, the urea tank automatically sprays diesel exhaust fluid. The diesel exhaust fluid and NOx undergo a redox reaction in the SCR catalytic reaction tank, producing non-polluting nitrogen and water vapor, which are then released.

Is the Highway Free During Mid-Autumn Festival?

Highways are not free during the Mid-Autumn Festival. Currently, highway toll exemptions are only applicable to major holidays, such as the highly valued Spring Festival, as well as other nationally significant holidays like Qingming Festival, Labor Day, and National Day. Additionally, there are specific requirements for vehicles—only passenger cars with seven seats or fewer are eligible for the toll exemption. Here is relevant information about the highway toll-free policy during holidays: 1. Overview: The holiday highway toll-free policy refers to the exemption of toll fees for small passenger vehicles during major holidays. 2. Policy Impact: Due to macroeconomic factors, although only passenger cars with seven seats or fewer are exempt from tolls during major holidays, the decline in manufacturing and economic activity has led to a noticeable drop in freight transportation demand in some regions. As a result, toll revenue during the free period is expected to decrease year-over-year. According to a report by Guojin Securities, this policy is projected to impact the performance of listed companies by approximately 5% to 10%.

What Type of Vehicles is 0W40 Engine Oil Suitable For?

0W40 engine oil is relatively viscous, making it suitable for older vehicles with significant mileage or certain American cars that have larger internal bearing clearances in their engines. 0W40 oil is particularly well-suited for German cars or older vehicles/engines (with considerable age). It is also appropriate for vehicles that frequently operate at high speeds or under heavy loads. For example, Volkswagen brand vehicles. Volkswagen engines employ slightly different technical processes compared to standard cars, featuring cast iron cylinder blocks with larger clearances between the cylinder walls and pistons. This necessitates higher viscosity oil to form thicker oil films, preventing piston seizure under high temperatures – a condition where 0W40 oil performs optimally. The designation "0W40" refers to the oil's classification. "0W" indicates excellent cold-start performance, capable of meeting engine starting requirements even at -35°C ambient temperatures. "40" denotes medium viscosity at 100°C, corresponding to a kinematic viscosity of 14.5 centistokes (cSt).

What are the causes of left front abnormal noise on bumpy roads for Honda CR-V?

The causes of left front abnormal noise on bumpy roads for Honda CR-V are: 1. Damage to the shock absorber plane bearing; 2. Loose lower control arm ball joint with excessive clearance; 3. Loose stabilizer bar bushing with excessive clearance. Methods to inspect left front abnormal noise on bumpy roads: 1. Press down hard on the bumper, if the vehicle bounces 2 to 3 times after releasing, it indicates the shock absorber is not damaged; 2. Drive on relatively flat roads at low speed, if the vehicle experiences strong vertical vibrations, it indicates a faulty shock absorber. Taking the Honda CR-V 2021 240TURBO manual two-wheel drive classic version as an example: It is a compact SUV launched by Dongfeng Honda, with a length, width, and height of 4621mm, 1855mm, and 1679mm respectively, and a wheelbase of 2661mm. It is equipped with a 1.5T turbocharged engine, with a maximum power of 142kw and a maximum torque of 243nm, matched with a 6-speed manual transmission.

What is the difference between Dual Engine and hybrid?

The differences between Dual Engine and hybrid are as follows: 1. Different scope: Hybrid has a broader scope. In a broad sense, Dual Engine belongs to hybrid. Narrowly speaking, there are two types of hybrid power in the world, one is called Dual Engine, and the other is called other hybrid power. Hybrid generally refers to oil-electric hybrid, where a car is equipped with both a conventional fuel engine and an electric motor, each operating under its optimal working conditions to achieve efficient energy utilization. 2. Different power: The electric power system used in commonly referred hybrid cars includes high-efficiency reinforced electric motors, generators, and batteries. The batteries used include lead-acid batteries, nickel-manganese hydrogen batteries, and lithium batteries. The hybrid technology of Dual Engine (HEV technology) belongs to full hybrid technology. Unlike other mild hybrid technologies, it has both an engine and an electric motor as power sources, significantly improving power performance while greatly reducing fuel consumption. It is a technology that combines tradition and the future, implementing energy-saving and emission reduction in practice, hence named "Dual Engine".

What are the causes of poor valve sealing?

Engine valve sealing issues can be caused by insufficient valve clearance, excessive carbon buildup on the valve contact surface, deformation of the valve seat, deformation of the valve head, valve spring failure, or rocker arm deformation. Additional details include: 1. Regular oil and oil filter changes: As oil passes through the fine pores of the oil filter, solid particles and viscous substances in the oil are trapped in the filter. If the filter becomes clogged, oil cannot flow smoothly through it, potentially rupturing the filter or forcing open the safety valve, allowing contaminants to bypass and return to the lubrication system. This accelerates engine wear and increases internal contamination. 2. Maintaining proper crankcase ventilation: Airborne contaminants can accumulate around the PCV valve, potentially clogging it. A clogged PCV valve can cause polluted gases to flow backward into the air filter, contaminating the filter element and reducing its filtration efficiency. This leads to dirtier air-fuel mixture intake, further polluting the crankcase, increasing fuel consumption and engine wear, and potentially causing engine damage. Therefore, regular PCV system maintenance is essential to remove contaminants around the PCV valve.

Should You Use Hot or Cold Air to Defrost the Windshield on Rainy Days?

Using cold air to defog the windshield on rainy days is generally faster. When cold air is blown onto the glass, the fog quickly dissipates, providing a rapid and direct effect. This happens because the cold air creates a "cold air film" on the glass surface, preventing carbon dioxide from condensing on the glass and thus achieving the defogging effect. Below are some methods for defogging car windows: 1. Apply Anti-Fog Spray: Spray a small amount of defogging agent onto the car window and wipe it clean. This removes dirt and stains while forming a thin, transparent protective film on the glass, effectively preventing moisture from condensing and forming fog. 2. Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when many people enter the car without turning on the air conditioning promptly, the exhaled humid air can quickly cause the windshield to fog up. In this case, turn on the air conditioning and direct cold air toward the windshield. The dehumidifying function will quickly remove the fog.
