What is the speed limit standard for urban roads?

Highway speed limits are generally 110-120km/h; primary roads, such as national highways and provincial roads, have a speed limit of 80km/h; suburban roads in urban areas have a speed limit of 70-80km/h; urban roads have a speed limit of 40-60km/h. Signage speed limit regulations: This refers to the speed indicated by speed limit signs and markings on the road. The specific speed limit is determined by the transportation department based on the road's design speed, functional type, geometric alignment characteristics, traffic flow, roadside environment, and other comprehensive factors. Road speed limit regulations: Regardless of the type of road, in sections with speed limit signs, drivers must adhere to the posted speed limits. In sections without speed limit signs, drivers must comply with the speed limits stipulated by laws and regulations.

What is the wading depth of the BYD Han EV?

The maximum wading depth of the BYD Han EV is 250mm. The wading depth of the BYD Han EV is determined by the height of the vehicle chassis, which is the ground clearance listed in the vehicle's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, off-road vehicles and SUVs have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the BYD Han EV is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before driving through water, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in the water, which could cause severe damage due to water intake. Assess the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, and other reference points such as the wheels and doors of other vehicles to estimate the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half of the tire height or the engine's air intake, do not proceed recklessly; consider alternative routes instead.

What are the differences between Maxus G10 and G20?

The differences between Maxus G10 and G20 are: 1. Difference one: Appearance: From the side view, the G20 and G10 are quite similar, but the G20 features a more minimalist overall design, with the sliding door negative pressure windows replaced by electric windows, representing a completely new design. Additionally, the rearview mirrors have been widened and now integrate LED turn signals and 360° panoramic imaging cameras. The taillights retain many design elements from the Maxus G10, but a chrome trim connects the taillights on both sides, enhancing the G20's cohesive appearance. 2. Difference two: Powertrain: Both the Maxus G10 and G20 are equipped with a 2.0T engine, but the G20 has undergone minor adjustments for compensation. However, the G20 sees significant changes in the transmission, upgrading from a 6-speed to an 8-speed automatic transmission sourced from ZF. This results in a maximum power output of 160kW (218PS) and a maximum torque of 350N·m, meeting the China VI emission standards.

Is overtaking allowed on one-way roads?

Overtaking is permitted on one-way roads as long as they are multi-lane with dashed lines. If overtaking occurs on solid lines, according to Article 90 of the "Road Traffic Law of the People's Republic of China," drivers violating road traffic safety laws and regulations regarding road usage rules will be subject to warnings or fines. According to Section 3, Article 9 of the "Scoring Standards for Road Traffic Safety Violations," illegally overtaking, failing to yield, or driving in the opposite direction will result in a 3-point penalty. Below are more related details: The "Scoring Standards for Road Traffic Safety Violations" stipulate: (1) Driving a passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20%. (2) Driving medium-sized or larger passenger or cargo vehicles, or hazardous material transport vehicles on roads other than highways or urban expressways, or driving other motor vehicles at speeds exceeding the limit by less than 20%. (3) Driving a cargo vehicle with a load exceeding the approved weight by less than 30%. (4) Driving a motor vehicle on a highway below the minimum speed limit. (5) Driving a motor vehicle prohibited from entering highways onto a highway. (6) Driving a motor vehicle on a highway or urban expressway without using the designated lane. (7) Driving a motor vehicle through a crosswalk without slowing down, stopping, or yielding to pedestrians as required. (8) Driving a motor vehicle in violation of prohibition signs or markings. (9) Driving a motor vehicle by illegally overtaking, failing to yield, or driving in the opposite direction. (10) Driving a motor vehicle while towing a trailer in violation of regulations.

Is the MG 5 Engine Domestic or Imported?

The engine used in the MG 5 is domestically produced, independently developed by SAIC Motor. The engine model used in the MG 5 is 15S4C, with a maximum horsepower of 120 hp, a maximum power of 88 KW, a maximum power speed of 6000 rpm, and a maximum torque of 150 Nm. For daily maintenance of the MG 5 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, change the oil regularly according to usage conditions and keep the oil volume moderate; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, it will either burst the filter element or bypass it through a safety valve, bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. When the amount is small, it suspends in the oil; when large, it precipitates, clogging filters and oil holes, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
