On a three-lane highway, the minimum speed limit for the middle lane is 90 kilometers per hour. For highways with three lanes in the same direction, the speed limits are as follows: the left lane is 110-120 km/h, the middle lane is 90-120 km/h, and the right lane is 60-120 km/h. If there are speed limit signs, the speed limits should be adjusted accordingly. For urban roads with three lanes in the same direction, there are no separate speed limits for each lane. Drivers must adhere to the speed limit indicated by road signs and should not exceed the posted limit. There is no minimum speed requirement, and in the absence of speed limit signs, the general speed limit is 50 km/h. Penalty points for speeding on highways: Exceeding the speed limit by more than 50%: Driving medium-sized or larger passenger or cargo vehicles, school buses, or vehicles transporting hazardous materials on highways or urban expressways at speeds exceeding the limit by more than 20%, or driving other motor vehicles at speeds exceeding the limit by more than 50% on roads other than highways or urban expressways, will result in 12 penalty points. Exceeding the speed limit by less than 20%: Driving medium-sized or larger passenger or cargo vehicles, school buses, or vehicles transporting hazardous materials on highways or urban expressways at speeds exceeding the limit by less than 20%, will result in 6 penalty points.

What is the fuel consumption of the Tang DM?

The fuel consumption of the Tang DM-i is 5.5L/100km. Below are its related introductions: Engine Introduction: The Tang DM-i adopts the same Xiaoyun-PHEV dedicated turbocharged 1.5Ti high-efficiency engine as the other two DM-i models, with a maximum power of 102kW (139 horsepower)/5200rpm and a maximum torque of 231Nm/1350rpm-4000rpm. Reasons for Energy Efficiency: The compression ratio reaches 12.5 in terms of craftsmanship, and the peak thermal efficiency is pushed to 40%. The motor as a whole has the advantages of small size and high efficiency: The presence of EHS allows the vehicle to achieve series, parallel, and engine direct drive modes, indirectly replacing the transmission. The addition of technologies such as a 16000rpm high-speed motor, flat wire winding, and oil-cooled heat dissipation gives the motor the advantages of small size and high efficiency.

What is the real fuel consumption of the Tang DMI?

The real fuel consumption of the Tang DMI is as low as 5.3L/100km for the 52km range version, while the 112km range version has a fuel consumption of 5.5L/100km. Below is an introduction related to fuel consumption: Habits and road conditions: Fuel consumption is greatly influenced by driving habits and road conditions. Avoid heavy acceleration and opt for gradual acceleration when starting to save the most fuel. To save fuel, avoid pressing the accelerator pedal hard when starting, as hard acceleration can increase fuel consumption by 2 to 3 times compared to normal acceleration. Braking: Maintaining a safe distance and avoiding frequent braking saves more fuel. If you don't maintain a safe distance, you may need to brake frequently on the road. When braking, the automatic transmission shifts to a lower gear, requiring the car to accelerate again from a lower gear, which consumes more fuel as the engine needs higher fuel intake when starting from a standstill or low speed.

What to Do When the Brakes Become Stiff and Hard to Press While Driving?

If you encounter brake failure while driving, try pressing the brake pedal multiple times to increase the chance of restoring braking force. Once you notice a brake malfunction, repeatedly press the brake several times. This will apply pressure to the brake system if there is air in the oil lines, and with repeated pressing, there is a chance the braking force may be restored. If you detect a brake issue, turn on the hazard lights to alert surrounding vehicles. In a critical situation where the brakes fail, slow down while using lights and horn to warn nearby vehicles, then call for emergency assistance. Causes of brake failure: Lack of necessary maintenance on the brake system, excessive impurities in the master cylinder, poor sealing, vacuum booster failure, contaminated brake fluid or mixing different types of brake fluid leading to vapor lock, leakage in the master or wheel cylinders, or air leaks in the air reservoir or pipe connections. Severe overloading increases the vehicle's inertia due to gravitational acceleration, directly causing brake failure. Improper operation leading to mechanical failure, such as using non-OEM floor mats (which can slip), driving in high heels/thick-soled shoes/slippers, may prevent full depression of the brake pedal, resulting in insufficient braking force and brake failure.

What are the symptoms of a faulty carbon canister?

The symptoms of a faulty carbon canister are as follows: 1. Abnormal noises while driving: A clicking sound can be heard when the engine is running at non-idle speeds. The carbon canister purge valve produces intermittent switching actions when the throttle is opened, resulting in noise, which is normal. 2. Strong gasoline odor: If you experience hesitation during acceleration and notice a strong gasoline smell inside the car, check for any leaks in the carbon canister system's piping. Gasoline vapors may escape directly into the atmosphere through damaged areas, causing the strong odor. 3. Engine stalling or difficulty starting: If the purge valve remains constantly open, the engine's intake mixture will remain overly rich. Additionally, since the engine control unit has not yet activated the carbon canister purge valve, it will not issue a command to reduce fuel injection. This can lead to an overly rich mixture during hot engine conditions, causing stalling and difficulty restarting after the engine stalls.

What is the fuel tank capacity of the Explorer in liters?

The fuel tank capacity of the Explorer is 73 liters, as officially announced. The Explorer requires 92-octane gasoline, with a fuel consumption of 8.7-9.0L per 100 kilometers. A full tank can cover a distance of 811-839km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is recommended to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
