Differences Between Vehicles That Use Urea and Those That Don't

Vehicles that use urea will experience engine torque limitation, reduced horsepower, and increased fuel consumption if urea is not used. Prolonged absence of urea can lead to partial or complete system damage, resulting in costly repairs, so it's advisable to address the issue promptly. Not all vehicles require urea; currently, only diesel engines do. The hazards of not using urea are as follows: 1. Environmental Pollution: Diesel vehicles without urea can have a severely negative impact on the ecological environment, which is also against national laws and regulations. 2. Damage to the SCR Injection System: Prolonged absence of urea may cause crystallization and blockage in the SCR system's nozzles, pipelines, and urea pump, or damage due to high temperatures. 3. Reduced Power: This is not a direct result of not using urea, but rather because the engine's electronic control system forcibly limits torque output when it detects no urea injection and excessive tailpipe emissions.

What are the test items for the small car subject 2 exam?

Small car subject 2 exam items include reverse parking, parallel parking, hill start, right-angle turn, and curve driving. Subject 2 exam opportunities: There are five successful booking opportunities for the motor vehicle driver's license subject 2 exam. If the exam is not passed on the last opportunity, the qualification for the motor vehicle driver's license exam will be canceled, and you cannot continue to take the exam. If you want to re-obtain the motor vehicle driver's license, you can only re-register at the driving school and start the exam again. Subject 2 deduction criteria: Not wearing a seat belt deducts 100 points, starting the engine without the gear in neutral deducts 100 points, not using the turn signal (including starting, changing lanes, overtaking, turning, and parking by the roadside), the turn signal not being on for more than three seconds, forgetting to turn off the turn signal or using the turn signal incorrectly deducts 10 points, etc.

How to Reset the Total Mileage on a Wuling?

Locate the position on the car's clutch housing (note that this position may vary—some vehicles have it on the transmission or driveshaft odometer sensor plug), then gently pull it out by hand; Next, insert the output clip of the mileage adjuster into the signal socket of the pulled-out sensor plug, and accurately insert the mileage adjuster into the cigarette lighter; Turn it slightly, adjust the small knob on the dashboard, and set the car's mileage to the desired value.

Should a Lean Fuel Mixture Be Repaired?

Of course, a lean fuel mixture should be repaired. Additional information is as follows: 1. Consequences of a lean fuel mixture: If the fuel system is running lean, it is necessary to immediately go to the nearest repair shop for inspection. Continuing to drive may result in reduced acceleration, increased fuel consumption, and in more severe cases, engine stalling. A lean fuel mixture occurs when the engine's oxygen sensor detects incomplete combustion of gasoline, characterized by too much air and too little fuel. Causes of a lean fuel mixture include insufficient fuel pressure, faulty oxygen sensors, malfunctioning air flow meters, intake system leaks, clogged fuel injectors, etc. 2. Automotive fuel system: The fuel system is responsible for fuel filling and transportation, ensuring that fuel smoothly reaches the engine to power its operation. It also collects fuel vapors, filters them, and releases them into the atmosphere. When the engine is running, the ECU detects the conditions for opening the charcoal canister purge valve. Once opened, fuel vapors are drawn into the engine under the vacuum of the intake manifold to participate in combustion.

Will the car owner be held responsible if lending the car to someone who drives under the influence?

The car owner is not at fault and will not bear compensation liability. Since the latest Tort Liability Law came into effect on July 1, 2010, the law clearly stipulates that in the event of an accident caused by lending a car to others, the losses shall be borne by the insurance company and the driver. If the car owner is not at fault, they will not be liable for compensation. In other words, under normal circumstances, as long as the car owner lent the car to a friend who was not drinking at the time, and the friend drove under the influence after borrowing the car, and the car owner has no other faults, then the car owner will not be liable for compensation. The car owner's faults generally include the following situations: 1. Lending the car to someone without a driver's license or whose license has expired, been revoked, or confiscated; 2. Lending the car to someone who is drunk; 3. Lending the car to someone whose driver's license type does not match the vehicle type.

Does Mercedes-Benz ECO Mode Damage the Car?

Mercedes-Benz ECO mode does not damage the car. The Mercedes-Benz ECO is an energy-saving mode that helps conserve fuel when activated. How ECO mode works: The ECO mode primarily makes comprehensive judgments and analyses during vehicle movement regarding factors that affect fuel consumption, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal fuel quantity to supply the engine for operation, effectively reducing fuel consumption compared to normal driving mode. Limitations of ECO mode: When the vehicle speed exceeds 120 km/h, priority is given to maintaining speed, and the ECO mode automatically deactivates. The ECO mode mainly functions through computer-controlled operations while the vehicle is in motion, so it does not work during idle stops or when in N, P gear, or manual mode. Additionally, when overcoming certain resistance or requiring high torque output, such as when climbing a slope, the ECU prioritizes ensuring sufficient power to drive the vehicle, and the ECO mode will not operate.
