What is the relationship between RPM and gear?

When driving normally, the engine needs to shift to appropriate gears to maintain the RPM within the most fuel-efficient range of 1800-2200 RPM. The engine's fuel consumption curve is U-shaped, with the most economical range being between 1800-2200 RPM, and the most fuel-efficient point at 1800 RPM. Matching the right gear with the right speed is crucial; otherwise, it may cause lugging or severe engine vibration, eventually leading to stalling. Key considerations for shifting between RPM and gears are as follows: 1. First gear is for starting: Its gear ratio is similar to reverse gear, so it should not be used for prolonged high-speed driving. Generally, shift to second gear at around 2000 RPM. 2. Shift decisively: Avoid hesitation. Press the clutch pedal quickly and release it slowly. 3. When downshifting, press the clutch first before releasing the throttle: Otherwise, the engine will slow down the vehicle. 4. When upshifting, pre-load the throttle before releasing the clutch: Especially important during high-speed driving.

What brand of tires does Cavalier use?

Cavalier uses the following two brands of tires: 1. Goodyear Assurance pattern series, with specifications of 205/55R16. 2. Giti Comfort 228 series, with specifications of 195/65R15. Information about car tires is as follows: 1. Function: Car tires are one of the important components of a vehicle. They directly contact the road surface and, together with the car suspension, help to cushion the impact during driving, ensuring good ride comfort and smoothness. They also ensure good adhesion between the wheels and the road surface, improving the car's traction, braking, and off-road capabilities, while bearing the weight of the car. 2. Common types: (1) Radial tires: The specifications of radial tires include width, aspect ratio, inner diameter, and speed limit symbols. (2) Tubeless tires: Commonly known as "tubeless tires." These tires are less prone to heat buildup during high-speed driving. When punctured by nails or sharp objects, they leak air slowly, allowing the car to continue driving for a certain distance.

Why is it not advisable to overtake in rainy weather?

When driving in the rain, always pay attention to the speed and direction of the vehicle in front, and never accelerate to overtake just because the vehicle ahead is moving slowly. Especially on highways, where the speed of vehicles in each lane is relatively high, the driver's field of vision narrows. Coupled with slippery road surfaces, forcibly changing lanes to overtake can easily cause the wheels to skid with just a slight turn of the steering wheel, leading to collisions with other vehicles or even rollover accidents. The specific reasons are as follows: 1. Difficulty in judging distance: It becomes hard to accurately assess the distance to surrounding vehicles. 2. Poor visibility of overtaking signals: Drivers of nearby vehicles may not easily see overtaking signals. 3. Slippery roads: Vehicles are prone to skidding. 4. Other factors: It becomes difficult to promptly detect dangerous situations.

Why can't the car door be opened?

The reasons why the car door cannot be opened are as follows: 1. Remote control failure: mainly due to unresponsive buttons, low battery, environmental factors, strong signal interference or shielding, anti-theft system malfunction, or the need to re-match the remote control encryption. 2. Car door frozen in winter: In northern regions, winter temperatures are very low, often below freezing. After washing the car, residual water can accumulate in the door handle, lock, door frame gaps, etc. Overnight freezing turns the water into ice, firmly freezing the door shut, making it impossible to open in the morning. 3. Fault in the door lock mechanism itself: The probability of the door lock itself failing is very low, mostly occurring in older cars around 10 years old. No matter how high-end the car is, its working principle may not be commonly understood, but the structure of the door lock is relatively simple, basically consisting of a lock cylinder, lock block, central control motor, and operating mechanism.

What is the load capacity of a 700r16 tire in tons?

700r16 tires can carry approximately 5 tons. Generally, the load index of a vehicle is molded on the sidewall of the tire, indicating the maximum load capacity of the tire. For driving safety, this load limit should not be exceeded. In 700r16, 700 refers to the nominal section width of the tire, and 16 indicates that the diameter of the car wheel hub is 16 inches. The following are factors related to vehicle load capacity: 1. Vehicle category: Heavy-duty trucks have a higher maximum load capacity than mini trucks. 2. Length: Generally, the longer the truck, the greater the weight it can carry. 3. Design weight: Each truck is designed with its own load capacity, and depending on the type of truck and the materials used in its design, there can be significant differences in load capacity. 4. Power: Generally, the larger the engine displacement of a truck, the greater its power, and thus the greater the weight of cargo it can carry.
