What are the current methods for treating automobile exhaust?

There are mainly the following methods for treating automobile exhaust: 1. Direct method: First, the carbon particles in diesel engine exhaust are captured by a collector and catalytically converted. The nitrogen oxides in the exhaust are then reduced or directly decomposed in a second catalytic converter using a suitable reducing agent. 2. Indirect method: Simultaneously eliminate carbon particles and nitrogen oxides in the exhaust on a catalytic collector, i.e., use the particulate matter (PM) collected on the filter to reduce (NOx). Here is some additional information: 1. Introduction: Diesel engine exhaust has an extremely complex chemical composition, and the composition of the exhaust varies significantly with engine operating conditions. 2. Types: The emitted pollutants include carbon soot particulate matter (PM), nitrogen oxides (NOx), CO, and hydrocarbons (HC), among others.

Will Fuel Consumption Decrease After the First Car Maintenance?

Fuel consumption may not necessarily decrease after the first car maintenance. Generally, there might be some changes in fuel consumption after the first maintenance—it could either decrease or increase. Since the components inside the engine have fully broken in after the running-in period of a new car, fuel consumption might decrease slightly. Below are some additional tips on how to drive fuel-efficiently during the car's running-in period: 1. Generally, keep the engine speed below 3,000 RPM, or below 3,500 RPM for automatic transmissions. 2. Avoid maintaining a single gear for too long or driving at low speeds for extended periods. 3. Do not overload the vehicle. 4. Avoid driving for excessively long durations.

What Causes the Engine Oil Cap to Be Too Tight to Unscrew?

If you have just driven the car, you can wait for the engine temperature to drop before attempting to open it. The oil cap may be difficult to unscrew due to excessive suction. Below is some information about engine oil: 1. Function: Engine oil is crucial for the engine. It not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. When the engine is running, the oil forms a thin film on the surfaces of various components, preventing direct contact and friction between them. 2. Precautions: Over time, the performance of engine oil degrades, so it needs to be replaced regularly. Failure to change the oil for extended periods can accelerate engine wear.

Should the car be in P or N gear when warming up?

Generally, the car should be placed in P gear when warming up. In fact, there is no difference between P gear and N gear for the transmission during warm-up. N gear is designed only to temporarily disconnect power and restart after a short shutdown, and is not intended for warming up at all. The differences between P gear and N gear are: 1. Shutdown issue: When shifted into N gear, the car will not shut down, only the power will not be output to the drive wheels, and the car will not move. However, the wheels do not have braking force, which poses a risk of rolling back or moving. When shifted into P gear, the parking brake device inside the transmission will lock the output shaft, the car will have no power, and it will have a certain braking effect. 2. Brake pedal: Shifting from P gear to any other gear requires stepping on the brake pedal, while N gear does not have as many restrictions. This is a safety setting to ensure driving safety. Otherwise, the moment the car is shifted from P to R or D, it will immediately have driving force backward or forward, and the handbrake alone may not be enough to stabilize the car, which can easily cause danger. Moreover, manufacturers now design unlock buttons that do not allow shifting from P gear to other gears without stepping on the brake pedal.

What is the maximum capacity of a car fuel tank?

Generally, small cars have a fuel tank capacity of 35-45 liters, while medium-sized cars have a fuel tank capacity of around 55-75 liters. Here is some related information about car fuel tanks: 1. Description: After filling up the tank, a car can usually travel around 500 kilometers. The size of the fuel tank depends on the car's displacement and fuel consumption—larger fuel consumption means a larger tank, and smaller fuel consumption means a smaller tank. A larger fuel tank capacity generally allows a car to travel 400-600 kilometers. Lighter cars with smaller displacements have correspondingly smaller fuel tank capacities, while heavier cars with larger displacements naturally have larger fuel tank capacities. However, the maximum distance on a full tank is mostly between 400-600 kilometers. Of course, some off-road vehicles are exceptions. 2. How to check fuel tank capacity: This is usually done by observing the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5-6 segments, with each segment representing the remaining fuel capacity. Generally, when the fuel gauge shows only two segments remaining, it's time to refuel to avoid running out of gasoline while driving.

How Many Days Are Highways Free During Mid-Autumn Festival?

Free for 8 days, details are as follows: 1. Highway free period regulations: From 00:00 on October 1, 2020 to 24:00 on October 8, 2020, totaling 8 days. 2. Free period rules: Starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday. 3. Standards for highway free passage: For ordinary roads, the time is determined when the vehicle passes through the toll lane of the toll station. For highways, the time is determined when the vehicle exits the toll lane. Additional information: 1. Determining free eligibility: If a vehicle exits the toll lane during the free period, the entire trip is free. It is recommended not to wait in crowds for the free period to avoid 'artificial' congestion. 2. How highways operate during free periods No cards are issued at the entrance, and the exit barrier is lifted for passage. In previous years, congestion during highway free periods was caused by a sudden increase in vehicles on the road. Although free, cards were still issued, causing vehicles to slow down before entering the toll station and stop to receive a card.
