What Does 400 Newton-Meters of Torque Mean?

400 Newton-meters of torque is equivalent to 40 kilograms of force. Performance: 400 Nm of torque in a car represents the manifestation of force, comparable to a measurable 400 Nm force or 400 Nm of traction, similar to a speed of 80 kilometers per hour. Torque: Torque is a special type of moment that causes an object to rotate. Engine torque refers to the moment output from the crankshaft. At a fixed power level, it has an inverse relationship with engine speed—the faster the speed, the lower the torque, and vice versa. This reflects the vehicle's load capacity within a certain range. External torque is called torsion or external couple moment, while internal torque is referred to as internal couple moment or simply torque.

Can You Start the Vehicle Directly in P Gear?

You can start the vehicle in P gear. After shifting into P gear, the pawl gear at the end of the output shaft will engage and lock the output shaft. This effectively cuts off the power connection between the transmission and the wheels, preventing the wheels from rotating in the same direction. Starting the vehicle in P gear will not cause the car to jerk forward or roll backward. P gear stands for "Parking," which is used when parking the vehicle. When you reach your destination or need to park for an extended period, shift the gear lever into this position. Note: Always ensure the vehicle is completely stopped before shifting into P gear. Shifting into P gear before the vehicle has fully stopped can cause mechanical damage to the automatic transmission. When in P gear, the wheels are mechanically locked, preventing the vehicle from moving forward or backward. Therefore, always use P gear when parking on an incline. Additionally, during short stops (e.g., at traffic lights), it is best not to shift into P gear to avoid severe damage to the transmission in case of a rear-end collision. Besides P gear, automatic transmission vehicles also have other gear positions like R, N, S, M, L, and D, each with different gear combinations that deliver varying power outputs. The vehicle must "shift gears" at different speeds, selecting the appropriate gear combination to deliver power. Below is a detailed explanation: R gear: "Reverse" is used for backing up. Whether in a manual or automatic transmission, R is the reverse gear. Shifting into R gear allows the vehicle to move backward. This gear should only be engaged when the vehicle is stationary and the engine is idling. Never use R gear while the vehicle is moving forward, and be especially cautious with accelerator control when reversing. N gear: "Neutral" is also known as the neutral gear. You can shift into this gear and press the brake when waiting at traffic lights. If the wait is longer, it is recommended to engage the handbrake, allowing your foot to rest off the brake pedal. A common misconception is that shifting into N gear while coasting downhill or at high speeds saves fuel. This is incorrect and can damage the transmission. S gear: "Sport" mode delays gear shifts to provide more power, typically used for overtaking. M gear: "Manual" mode allows the driver to manually shift gears, similar to a manual transmission vehicle. L gear: "Low" gear is used for low-speed driving. In this gear, the transmission operates only in the lowest gear (equivalent to 1st gear in a manual transmission) and does not automatically shift to other gears. This gear is useful for climbing or descending steep slopes. In low gear, the drive wheels deliver high torque, providing sufficient power for steep climbs. Prolonged braking can overheat the brake pads, reducing braking efficiency, which is dangerous on long or steep descents. Shifting into L gear uses the engine's low RPM to control the vehicle's speed, reducing the need for constant braking. D gear: "Drive" is used for normal driving. Shifting into this gear and pressing the accelerator allows the vehicle to move. In this gear, the transmission automatically shifts based on speed and throttle input. You can remain in D gear and press the brake at traffic lights. However, prolonged stops in D gear can raise transmission fluid temperature and degrade its quality.

Can Grapefruit Peel Remove Odors Inside the Car?

Grapefruit peel cannot remove odors inside the car. Methods to disperse odors inside the car: Opening car windows for ventilation is the simplest, most convenient, and cost-effective method to disperse toxic gases inside the car. Car-activated carbon has the function of adsorbing toxic substances. Photocatalyst is a metal oxide that, when applied to the interior, can degrade harmful substances inside the car under light. Placing a car air purifier inside the vehicle. Extension: Odors inside the car can easily attract the attention of car owners. Using items like grapefruit peel to remove odors does not work. Therefore, it is very important to correctly eliminate toxic gases inside the car, and also to avoid exposing the vehicle to excessive sunlight.

Will the car catch fire if the lights are left on?

Leaving the lights on will not cause the car to catch fire. Introduction to car lights: Keeping the lights on for a long time is unlikely to cause a fire, but it may drain the vehicle's battery. Car lights refer to the lamps on a vehicle, which serve as tools for road illumination during nighttime driving and for signaling various driving indications. Composition of car lights: Position lights: used to alert other road participants; Turn signals: provide signals to other drivers and pedestrians when the vehicle is turning; Headlights: composed of low beams and high beams, used for illumination; Fog lights: used in foggy weather as a lighting signal; Reverse lights: alert pedestrians and vehicles behind; Brake lights: alert following vehicles.

What is the traffic jam emergency number?

Dial "122" for traffic jams. Precautions during traffic jams: When encountering a traffic jam, immediately turn on the hazard lights, and ensure that passengers do not exit the vehicle or move around casually. Wait patiently inside the vehicle. For trucks experiencing traffic jams at night, drivers should try to stay alert to ensure they can hear the traffic police's siren signal indicating the resumption of traffic before moving forward. 122 Emergency Service Platform: The 122 emergency service platform is a department established by public security traffic management authorities to receive public reports of traffic accidents, dispatch police officers to handle various emergencies and assistance requests, and also to accept public reports, complaints, and inquiries regarding traffic management and traffic police law enforcement issues.

Does a deformed crash beam need to be replaced?

Whether a deformed crash beam needs replacement depends on the extent of its deformation. Introduction to crash beams: A crash beam is a U-shaped channel formed from cold-rolled steel plates, connected to the vehicle frame longitudinal beams. As the first barrier of passive safety in automobiles, the crash beam serves as an important safety device that absorbs and mitigates external impact forces, protecting the front and rear of the vehicle body. Minor deformation: A crash beam with minor deformation can still provide good protection. Even without replacement, it's not a big issue as long as it undergoes minor repairs. Severe deformation: Severe deformation is difficult to repair through panel beating. In such cases, replacement is definitely necessary since the crash beam can no longer ensure good impact safety performance.
