What is the appropriate normal kPa for wheel pressure?

1 Answers
MacLawson
07/25/25 2:05am
Wheel pressure is normally appropriate at around 250 kPa. Tires are the only components of a car that come into contact with the ground, and they are crucial for the vehicle's driving stability and safety. Tires are very important for a car, and tire pressure is equally important for the tires. The tire pressure should neither be too high nor too low. If the pressure is too high, it will reduce the contact area between the tire and the ground, leading to decreased tire grip. If the pressure is too low, it can cause wave-like deformation of the tire during high-speed driving, which accelerates tire aging and increases the risk of a blowout. Tires are made of rubber, and rubber products will age over time with prolonged use, so tires need to be replaced regularly.

How many kilometers can a motorcycle travel on one bar of fuel?

Tank capacity is about 6 liters, with actual fuel consumption around 3 liters per 100 kilometers. When the fuel gauge pointer reaches the red zone after a full refuel, it can typically travel approximately 100-120 kilometers. If all the fuel in the tank is completely used up, the motorcycle can travel about 200 kilometers. Below are the characteristics of motorcycle engines: Engine: Two-stroke or four-stroke gasoline engine. Cooling method: Air-cooled, with two types - natural air cooling and forced air cooling. Most models use natural air cooling, which relies on air flowing over the cylinder head and cylinder sleeve fins during riding to dissipate heat. High-power motorcycle engines, to ensure cooling at low speeds or before starting, use forced air cooling with a fan and air duct to direct air over the cooling fins. Engine speed is high: generally above 5,000 RPM. Power-to-displacement ratio (effective power output per liter of engine displacement) is large, typically around 60 kilowatts per liter.

Can You Directly Apply the Brakes to Stop in Fourth Gear?

Yes, you can. First apply the brakes to slow down, and then press the clutch when you are about to stop. There are two reasons for this: first, pressing the clutch too early is equivalent to coasting in neutral, which is dangerous. Second, modern vehicles are either fuel-injected or direct-injected, and coasting in gear is more fuel-efficient than coasting in neutral. When accelerating, it is also recommended to wait until the speed increases before shifting up. Below is relevant information: Normal deceleration: Press the brake while downshifting. The timing for downshifting varies by vehicle; you can monitor the RPM or speed to ensure the engine speed does not drop below 1000 RPM during deceleration. If decelerating to a complete stop (e.g., at a red light, when the road ahead is clear, or when no further acceleration is needed), you can press the clutch while braking and shift to neutral once the vehicle has stopped or is about to stop. On downhill sections, regardless of the situation, you must downshift sequentially and avoid coasting with the clutch pressed.
