What is Fuel Economy?

Fuel economy refers to the ability to complete unit transportation work with minimal fuel consumption. The following is relevant information about fuel economy:1. Economic indicators: There are three evaluation indicators for economy: fuel consumption per unit distance traveled, fuel consumption per unit transportation workload, and distance traveled per unit of fuel consumed. In China, testing mainly focuses on the first indicator. 2. Differences: The fuel economy indicators of gasoline are related to engine characteristics, vehicle weight, speed, various motion resistances such as air resistance, rolling resistance, and climbing resistance, as well as the efficiency and reduction ratio of the transmission system. Therefore, the numerical values often differ from actual conditions.

What is the method for shifting gears in an automatic transmission while waiting at a red light?

Automatic transmission shifting methods while waiting at a red light are: 1. For red lights under 30 seconds, the driver can simply keep their foot on the brake; 2. For red lights between 30 seconds and 1 minute, shift to N gear and engage the handbrake; 3. For red lights over one minute, shift to P gear and engage the handbrake. The gears in an automatic transmission include: 1. P (Parking gear, starting gear); 2. R (Reverse gear); 3. N (Neutral gear); 4. D (Drive gear); 5. L (Low gear); 6. S (Sport mode); 7. OD (Overdrive gear). The correct usage methods for an automatic transmission are: 1. The vehicle can only be started in P or N gear. To shift out of P gear, the brake must be pressed. Turn on the power, press the brake, shift to N gear, and after ignition, shift to D gear to move forward; 2. When switching between N, D, and 3 gears, there is no need to press the shift button. To shift down from 3 gear to lower gears, the shift button must be pressed, but shifting from lower to higher gears does not require pressing the shift button; 3. Do not shift into N gear while driving to coast; 4. Never shift into P gear while driving; 5. After driving, the engine must be turned off and shifted into P gear before the key can be removed.

What is the Difference Between Full-Face and Half-Face Helmets?

Here are the specific differences between full-face and half-face helmets: 1. Safety factor: The main difference between full-face and half-face helmets lies in their safety levels. Compared to half-face helmets, full-face helmets offer significantly higher safety, providing excellent protection for the head by fully enclosing it. 2. Warmth factor: Full-face helmets offer complete head protection but lack ventilation, which can make them feel stuffy when worn. They are more suitable and warmer for winter use. Half-face helmets, on the other hand, provide better visibility and ventilation but are not ideal for winter. 3. Applicability: Full-face helmets are generally more suitable for electric bike riders or off-road racing, while half-face helmets, due to their lack of chin and back-of-head protection, are banned in many countries.
