What is 1490kg curb weight in tons?

The curb weight of 1490kg is 1.49 tons, where every 1000 kilograms equals one ton. Below is relevant information about curb weight: The role of vehicle curb weight: The curb weight of a vehicle is an important parameter affecting its power performance, fuel economy, and fuel consumption. There is a proportional relationship between a vehicle's fuel consumption and its curb weight - the heavier the curb weight, the higher the fuel consumption. However, a lighter curb weight isn't always better, nor is a heavier one necessarily worse. Vehicles with greater curb weights offer better stability, especially during sharp turns and emergency braking, where their advantages become particularly evident. Development trends in vehicle curb weight: Current automotive manufacturing trends focus on lightweight design, environmental protection, and energy efficiency. The extensive use of lightweight materials such as aluminum and plastics in vehicle construction has led to a decreasing trend in curb weights.

Is 1.9bar Tire Pressure Normal?

Tire pressure of 1.9bar is abnormal. You need to inflate the tires to around 2.5bar. Function of tire pressure: "Tire pressure" refers to the air pressure inside the tire. Both overinflation and underinflation will affect the service life of the tire. Underinflation will increase tire body deformation, easily cause cracks on the tire sidewall, increase the contact area between the tire and the ground, accelerate shoulder wear, and correspondingly increase fuel consumption. Tire pressure precautions: Maintaining proper tire inflation provides the best combination of handling, tread life and driving comfort. It is recommended to check tire pressure regularly, including the spare tire. Even in good condition, tire pressure may decrease by 10-20 kPa per month and should be checked periodically.

Why do the headlights turn on when braking?

The reason why the headlights turn on when braking is: after prolonged use, the filaments of the brake light bulbs become thinner, reducing their power. The excess current then flows to the headlights, causing them to light up. Solution: Check whether the wiring of the headlights is connected to the wiring of the brake lights. When the lights are turned on, the rear lights that illuminate are the small lights, also known as the marker lights, not the brake lights turning on when the headlights are activated. Reasons why the brake lights may not work: Common causes include a burnt-out bulb, a blown fuse, or a damaged brake switch. If the bulb is burnt out, simply replace it. The fuse is located in front of the driver's left knee—open the cover to see it, with specific labels on the cover. The brake switch is located at the top of the brake pedal. It is recommended to visit a repair shop for replacement.

Does the car handbrake brake the front wheels or the rear wheels?

The handbrake of a car always brakes the rear wheels. Introduction to Handbrake: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake will cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel distance will increase. A return spring is also used in conjunction with the handbrake. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. Long-term use of the handbrake will also cause corresponding deformation of the spring. Handbrake Principle: For small cars, some handbrakes are located behind the transmission, where there is a brake disc connected to the drive shaft, similar to a disc brake. The pulling force is transmitted there through the steel cable to achieve parking braking.

What Are the Specifications and Models of Seat Belts?

Currently, there are three main types of seat belts used internationally in automobiles: three-point seat belts, two-point seat belts, and four-point seat belts. Generally, three-point seat belts are installed in most vehicles. Precautions for Using Seat Belts: Do not drive or ride in a vehicle if the seat belt is damaged, as it cannot provide adequate protection in the event of a collision. When fastening or unfastening the seat belt, ensure it is not twisted, as a twisted seat belt cannot effectively absorb the impact force during a collision due to its width. The Role of Seat Belts: Automotive seat belts function to restrain movement and provide cushioning, absorbing the energy of an impact and converting it into inertial force. This helps prevent or reduce the severity of injuries to drivers and passengers, thereby enhancing safety.

Where to Get a Physical Examination for Driving School?

Driving school physical examinations are conducted at hospitals. Generally, second-class A-level hospitals or above can perform driving school physical examinations, and they have dedicated departments for this purpose. No appointment is needed for the examination; simply bring the specialized physical examination form provided by the driving school to a second-class A-level hospital or above. Specific examination items include: Age: 18-70 years old; Height: No restriction; Vision: Naked or corrected vision of both eyes must reach 4.9 on the logarithmic vision chart (equivalent to 0.8 on the E-chart); Color discrimination: No red-green color blindness; Hearing: Able to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork; Upper limbs: Both thumbs must be intact, and each hand must have at least three other fingers intact, with normal limb and finger movement functions; Lower limbs: Normal movement function, with a length difference of no more than 5 cm; Trunk and neck: No movement dysfunction. Definition of a Driver's License: A driver's license, officially known as a motor vehicle driver's license and also referred to as a "driving license," is a document required by law for individuals to operate motor vehicles. Driving a motor vehicle requires certain skills, and those lacking such skills may cause traffic accidents if they drive recklessly. Generally, individuals without a license are not permitted to drive on public roads.
