Is Automotive Urea Harmful to the Human Body?

The human body naturally produces urea, so contact with the skin generally does not cause any harm. However, at high temperatures, automotive urea can easily release ammonia gas, which has corrosive properties. Prolonged skin exposure may lead to pigmentation or ulcers. Therefore, if you come into contact with automotive urea, rinse it off with clean water as soon as possible. Below is more information about automotive urea: 1. Function of Automotive Urea: Automotive urea is used in the Selective Catalytic Reduction (SCR) system of diesel vehicles to catalytically reduce nitrogen oxides (NOx) in exhaust gases into harmless nitrogen (N₂) and water (H₂O), which are then emitted. 2. Working Process of Automotive Urea in the SCR System: The SCR system is a closed-loop injection system. When exhaust gases exit the engine combustion chamber, an electric pump draws a sufficient amount of urea solution from the urea tank based on commands from the electronic control unit. The urea solution is mixed and atomized with compressed air before being evenly injected into the exhaust stream through the urea nozzle. Under high temperatures, the urea solution rapidly decomposes into NH₃ (ammonia), which then reacts with NOx in a catalytic reduction process, ultimately producing harmless N₂ and H₂O for emission.

What should be noted before driving a motor vehicle into a highway tunnel?

Before driving a motor vehicle into a highway tunnel, the following points should be noted: 1. Turn on the low beam headlights. Entering a tunnel is equivalent to driving at night, so low beam headlights should be turned on. This is to avoid affecting oncoming vehicles and vehicles ahead. Overtaking is not allowed inside the tunnel unless in emergency situations. 2. Pay attention to traffic signs and speed limit signs before the tunnel. When driving inside the tunnel, a strong sense of speed may be experienced. Do not panic in this situation; appropriately reduce speed and focus your eyes on the far end of the road. 3. Observe the situation ahead in your lane in advance and avoid changing lanes arbitrarily. Then enter the tunnel lane, noting that lane changes are not allowed inside the tunnel. There is no problem when exiting the tunnel; you can turn off the headlights during the day and then drive at the prescribed speed.

What to Do When a Motorcycle Won't Start After Long Inactivity?

Motorcycle won't start after long inactivity? Here are the solutions: 1. Check if the ignition system works by examining whether there's spark output from the spark plug high-tension wire. A visible spark indicates normal operation; if not, the ignition system needs repair. 2. Verify fuel presence in the carburetor by closing the fuel tank valve and loosening the carburetor's drain screw at the bottom. No fuel inside usually causes starting failure - add appropriate fuel if needed. 3. Inspect carburetor choke operation. Starting issues typically stem from fuel delivery or ignition systems. Ensure the choke functions properly, and repair if faulty.

What to Do in Case of a Car Collision?

Here are the steps to handle a car collision: 1. Minor accident with no injuries: This situation is straightforward and easy to resolve. Typically, the parties involved negotiate privately, with the at-fault party compensating the non-liable party. If negotiations fail, call the police and notify the insurance company. 2. Serious accident with no injuries: In this case, you must call the police and notify the insurance company, waiting for the traffic police to issue a liability determination. 3. Accident with injuries: For such incidents, first dial 120 (emergency services) and then 122 (traffic police). Chinese law clearly stipulates that in accidents with injuries, priority must be given to ensuring the safety of the injured. After the traffic police arrive, follow their instructions for further actions.

Briefly describe the function of the crankshaft

The crankshaft is mainly used to convert the gas pressure of the piston-connecting rod assembly into torque and output it to the outside. The crankshaft is also used to drive the engine valves and other auxiliary devices. The following is a related introduction to the working principle of the crankshaft mechanism: 1. Working principle: The crank-connecting rod mechanism is the main mechanism of a reciprocating piston engine that converts thermal energy into mechanical energy. Its function is to convert the pressure of the gas acting on the top of the piston into power that enables the crankshaft to rotate and output power externally. During the engine operation, the gas pressure generated by fuel combustion directly acts on the top of the piston, pushing the piston to perform reciprocating linear motion. Through the piston pin, connecting rod, and crankshaft, the reciprocating linear motion of the piston is converted into the rotational motion of the crankshaft. 2. Composition of the crankshaft mechanism: The form of the crank-connecting rod mechanism depends on the number of cylinders and the arrangement of the cylinders. Engines with different numbers of cylinders and structures have different crank-connecting rod mechanism structures. The crank-connecting rod mechanism mainly consists of three parts: the engine block group, the piston-connecting rod group, and the crankshaft-flywheel group.
