In the event of a dashboard warning light indicating a fault and power loss, you should immediately stop the vehicle and call for a tow truck or wait for assistance. For safety reasons, do not attempt to continue driving. There are three main reasons why the engine warning light may come on, accompanied by insufficient power or a complete loss of power: 1. Poor combustion of the air-fuel mixture in the engine: When the mixture in the cylinders is too rich, the vehicle may experience knocking or shaking. Conversely, if the mixture is too lean, the vehicle may exhibit poor acceleration. 2. Issues with the air-fuel mixture: This could be due to faults in the spark plugs, high-voltage wires, or ignition coils. Poor performance in the ignition system or weak sparking from the spark plugs can also trigger the engine warning light, causing the vehicle to shake and lose power. 3. Abnormal fuel supply pressure or faults in the intake pressure sensor: If the fuel pump's supply pressure is irregular or the intake pressure sensor provides incorrect readings or malfunctions, it can lead to vehicle shaking and insufficient power.

What is the freezing point of antifreeze in degrees below zero?

The freezing point of antifreeze ranges from -40 to -60 degrees Celsius, while water freezes at 0 degrees Celsius. It is necessary to add antifreeze to the radiator when the temperature approaches 0 degrees Celsius. The functions of automotive antifreeze are: 1. Providing anti-corrosion protection for components of the cooling system; 2. Preventing scale formation to avoid reducing the radiator's heat dissipation efficiency; 3. Ensuring the engine operates within the normal temperature range. Precautions for using antifreeze include: 1. Regularly checking the antifreeze level and replenishing it promptly if it falls below the lower limit; 2. Observing whether the antifreeze has any turbid sediments and replacing it in time if turbidity is found; 3. Not mixing antifreeze of different colors as they vary by vehicle model; 4. Measuring the freezing point of antifreeze before winter to prevent it from freezing.

How is speeding calculated?

The calculation formula for speeding is (actual speed minus speed limit) divided by speed limit multiplied by 100%. Speeding refers to when a driver operates a motor vehicle at a speed exceeding the legal limit. If the speed exceeds the limit by less than 10%, the driver will receive a warning without fines or penalty points. Penalty points for speeding include: 1. For ordinary small motor vehicles exceeding the speed limit by 20% to 50%, 6 points will be deducted; 2. For medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles exceeding the speed limit by 20% to 50% on non-highways or urban expressways, 6 points will be deducted; 3. For medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles exceeding the speed limit but by less than 20% on highways or urban expressways, 6 points will be deducted.
