Can You Open the Hood to Extinguish a Fire in the Engine Compartment?

You should not open the hood to extinguish a fire in the engine compartment. If the engine compartment is on fire, keeping the hood closed limits the entry of air, preventing the fire from growing. Opening the hood allows a large amount of air to enter, which contains oxygen that can fuel the fire, causing it to spread more rapidly. The correct approach is: Quickly turn off the engine and use a covering method or a fire extinguisher to put out the fire. Stand upwind, keep as far away from the fire as possible, and aim the fire extinguisher at the source of the fire. When fighting the fire, the correct actions include: Remove any synthetic fiber clothing, protect exposed skin, and avoid breathing through your mouth or shouting loudly.

What is the purpose of adding urea to heavy-duty trucks?

Diesel engines use urea to catalyze nitrogen oxides (NOx) emitted from the engine. During operation, diesel engines produce harmful nitrogen oxide gases that pollute the atmosphere and pose health risks. When urea comes into contact with these NOx emissions, a chemical reaction occurs, converting them into harmless nitrogen and water vapor. Below are relevant details: 1. Urea standards: In China, qualified urea solutions typically consist of 32.5% high-purity urea mixed with purified water. This solution undergoes a reduction reaction with NOx, producing nitrogen, oxygen, and water, thereby reducing nitrogen oxide emissions. This method is applicable to all Euro IV and Euro V compliant diesel engine SCR systems. 2. Hazards of inferior urea: A truck's power and fuel consumption can be affected by urea quality. If a diesel vehicle lacks proper exhaust treatment systems or uses substandard products, it may trigger automatic engine deceleration and damage the SCR catalytic converter's catalyst.

What is the calculation formula for average speed in a speed monitoring section?

Average speed in the section = section distance / travel time. Below are the relevant details: 1. Section speed monitoring: Section speed monitoring refers to the method of detecting the average speed of motor vehicles passing through the road section (speed monitoring section) between two adjacent speed monitoring points. For example, if the distance of a speed monitoring section on a highway is 10 kilometers and the speed limit for that section is 120 kilometers per hour, a vehicle that takes 5 minutes or more to complete the section would have an average speed below 120 kilometers per hour, meeting the speed limit requirement; if the vehicle takes less than 5 minutes to pass through the section, it would be speeding. 2. Penalties for speeding in highway section speed monitoring are as follows: Speeding by less than 10% on highways or national roads results in a warning, with no points deducted or fines imposed; speeding between 10% and 20% results in 3 points deducted and a fine of 200 yuan.

Should You Overtake from the Left or Right on the Highway?

According to the Road Traffic Safety Law, whether on ordinary roads or highways, overtaking should always be done from the left side of the vehicle ahead. Overtaking from the right side is illegal. Additional details are as follows: 1. Before overtaking: Choose a straight, wide road with good visibility, no obstacles on either side, and no oncoming vehicles within 150 meters ahead. Ensure safety before proceeding to overtake. 2. During overtaking: Turn on the left turn signal and honk the horn (or flash headlights at night) to notify the vehicle ahead. After confirming that the vehicle ahead yields or signals to yield, slightly steer to the left, maintain a safe lateral distance from the vehicle being overtaken, accelerate to pass, and minimize the time spent side by side. 3. After overtaking: Continue driving in the overtaking lane. After passing the overtaken vehicle by 20-30 meters, turn on the right turn signal, return to the original lane, and then turn off the turn signal.

What does it mean when the driver's license issuance location information fails?

Driver's license issuance location information failure means that the traffic management system cannot retrieve the file information. This is usually caused by system failure preventing the driver's information from being found. Additional information: 1. Driver's license issuance location: The driver's license issuance location refers to the place where the license was issued, which is the local vehicle management office where the driver's license was obtained. The driver's license registration location is the personal residential address registered when applying for the driver's license. The vehicle license is a document for motor vehicles, serving as their 'identity proof'. 2. Driver's license: Driving a motor vehicle requires certain driving skills. People lacking such skills may cause traffic accidents if they drive randomly, so generally, unlicensed individuals are not allowed to drive on the road. However, for those who have already mastered safe driving techniques, the document that permits them to drive vehicles on the road is the 'driver's license'.

Can the Wuling Mini Last for 5 Years?

Can the Wuling Mini last for 5 years? The introduction of car maintenance cycles and the importance of maintenance is as follows: Car Maintenance Cycle: The maintenance cycle for motor vehicles is every 5,000 kilometers or every six months. Different brands of motor vehicles have different maintenance cycles. When performing vehicle maintenance, it is necessary to refer to the maintenance items in the user manual and the specific usage conditions of the vehicle to determine the relevant maintenance content. Importance of Car Maintenance: Maintaining a car ensures that the vehicle remains in excellent performance condition, ready for use at any time without worrying about technical issues; it effectively improves the vehicle's efficiency, reduces fuel consumption, and minimizes wear on parts and tires. For example, regular maintenance of the engine prevents an increase in fuel consumption and even makes it run more smoothly; it enhances driving safety by avoiding sudden problems during trips, thereby ensuring personal safety.
