What to do if the car is highly reflective? A complete guide to plateau driving
With the rise of self-driving travel, more and more car owners choose to drive to plateau areas. However, altitude sickness (referred to as "high altitude sickness") not only affects the human body, but may also affect vehicle performance. This article will combine the hot topics and actual cases on the Internet in the past 10 days to analyze the performance, countermeasures and precautions of high reflectivity in cars.
1. What is car high reflectivity?

Automobile hyperreflection refers to phenomena such as reduced power, increased fuel consumption, and difficulty in starting due to thin oxygen and reduced air pressure in areas with higher altitudes (usually more than 2,500 meters). The following are common manifestations:
| Symptoms | Reason | Multi-engine models |
|---|---|---|
| Less motivation | Insufficient oxygen leads to reduced combustion efficiency | naturally aspirated engine |
| Increased fuel consumption | ECU automatically adjusts air-fuel ratio | Turbocharged models are lighter |
| Difficulty starting | Insufficient battery voltage | Old battery vehicles |
| Weak brakes | Reduced air pressure affects vacuum assist | All models |
2. How to prevent and deal with high reflection in cars?
Based on recent car owner feedback and professional suggestions, the following practical methods have been compiled:
| measures | Specific operations | Effect |
|---|---|---|
| Advance maintenance | Replace high-grade engine oil and check air filter | Improve engine adaptability |
| Fuel selection | Fill with 95/98 gasoline | Reduce the risk of knocking |
| Control speed | Keep shifting above 3000 rpm | Make up for power loss |
| Prepare emergency tools | Carry portable oxygen bottles and anti-skid chains | Respond to emergencies |
3. Sharing of real cases from car owners
In recent hot discussions, many car owners shared their experiences of driving on plateaus:
1.@Chuan-Tibet line old driver: The power of turbocharged models decreases by about 20% at an altitude of 4,000 meters. It is recommended to accelerate in advance before going uphill.
2.@new energy car owner: Pure electric vehicles have no air intake problems, but their battery life is reduced by 30% and charging points need to be planned.
3.@ Maintenance Engineer Master Wang: Brake oil in plateau areas is prone to bubbles. It is recommended to replace the Dot4 grade oil before the trip.
4. Essential list for plateau driving
| Category | Items | function |
|---|---|---|
| vehicle equipment | Antifreeze glass water, tire pressure gauge | Coping with temperature differences and air pressure changes |
| emergency medicine | Rhodiola rosea capsules, oxygen tanks | Alleviate personnel’s high reaction |
| electronic equipment | Car inverter, satellite phone | Ensure communications and power supply |
5. Special precautions
1. Avoid long-term high-load driving and stop the engine every 2 hours to cool down the engine.
2. Gas stations on the plateau are far apart, so fill up your tank immediately when you see a regular gas station.
3. Prioritize engine braking on downhill sections to reduce the risk of brake overheating.
Summary: Although car high-reflection is inevitable, the impact can be significantly reduced through adequate preparation and scientific driving. It is recommended that car owners check real-time road conditions before traveling (you can pay attention to the plateau road warnings of the Ministry of Transport) to ensure a safe and smooth journey.
