What is the normal tire pressure for small cars?

The normal tire pressure for small cars is generally between 1.8 and 2.4 atmospheres. Typically, the front tires should be between 2.1 and 2.3 atmospheres, while the rear tires should be between 2.3 and 2.4 atmospheres. Normal tire pressure varies by season: in winter, it is advisable to increase the standard tire pressure by about 0.2 bar; in summer, if the car is parked outdoors, the pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Generally, a tire pressure between 2.3 and 2.5 is considered normal. If the car is fully loaded, a tire pressure of around 2.5 is more suitable; for two passengers, a tire pressure of 2.3 is also normal. The standard pressure can usually be found in the following places: the vehicle user manual, the label next to the driver's door, the drawer beside the driver's seat, or the fuel tank cap door.

What is exhaust pipe resonance during throttle release?

Exhaust pipe resonance during throttle release can be addressed by modifying the muffler to a single-stage backpressure configuration. Exhaust pipe resonance: The muffler can be modified to a single-stage backpressure setup while placing steel wool inside the muffler. After this modification, the muffler's vibration frequency will change from vibrating three times per exhaust cycle to vibrating once. Additionally, the steel wool can absorb some of the exhaust gas energy, but the steel wool's vibrations won't transfer to the muffler housing. Muffler service life Therefore, after modification, the muffler housing will experience significantly fewer vibrations compared to before. Moreover, the modified muffler's service life will be doubled. This modification method can also be applied to construction machinery and agricultural equipment. With absolutely no moisture inside the modified muffler, it will never rust internally. If the steel wool near the exhaust port is compressed to block dust, it can reduce PM2.5 emissions by more than 20%.

What does license renewal and archiving mean?

License renewal and archiving means that the driver's license has been successfully reviewed and transferred. The full name of the driver's license is the motor vehicle driver's license, also known as a driving license or driver's permit, which is a legally required certification for motor vehicle drivers. The following conditions must be met for license renewal and inspection: Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses have no demerit points in the current scoring cycle, or holders of other permitted vehicle-type driver's licenses have less than 12 demerit points in the current scoring cycle; Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses who have demerit points in a scoring cycle, as well as holders of other permitted vehicle-type driver's licenses who have been involved in a traffic accident resulting in death and assumed equal or greater responsibility without having their motor vehicle driver's license revoked, and have completed the required inspection education; The applicant has no pending road traffic safety violations or traffic accidents; The applicant's physical condition meets the driving permit requirements; The motor vehicle driver's license is not under any circumstances of being seized, detained, temporarily suspended, revoked, canceled, or annulled by law.

What is the capacity of the starter battery for new energy electric vehicles?

New energy electric vehicle starter batteries include nickel-metal hydride batteries with 80A.h, nickel-cadmium batteries with 55W.h/kg, and sodium-sulfur batteries with 760W.h/kg. Introduction to Nickel-Metal Hydride Batteries: Ovonie currently offers two types of unit batteries: 80A.h and 130A.h, with a specific energy of 75–80W.h/kg and a cycle life exceeding 600 cycles. Introduction to Nickel-Cadmium Batteries: Their specific energy can reach 55W.h/kg, and specific power exceeds 190W/kg. Introduction to Sodium-Sulfur Batteries: Their theoretical specific energy is 760W.h/kg, with practical values already exceeding 100W.h/kg, which is 3–4 times that of lead-acid batteries. Another feature is their ability to discharge at high currents and power. Their discharge current density can generally reach 200–300mA/mm2, and they can instantaneously release three times their inherent energy. Additionally, they have high charge-discharge efficiency.

Can You Start the Car If the Rear Door Is Not Fully Closed?

Can You Start the Car If the Rear Door Is Not Fully Closed? Warning for Unclosed Door: If the door is not fully closed, a loud alarm will sound, or there will be a clear warning on the dashboard. In this case, simply close and lock the door promptly. While driving, if you listen carefully, you may hear some noise, so you can detect and close the door in time. Additionally, when exiting the car, if the door is not properly closed, you may be unable to lock the car, and a loud alarm will sound, which effectively serves as an anti-theft measure. Hazards of an Unclosed Door: An unclosed door provides an opportunity for thieves. If someone leans against the door while the car is moving at high speed, it can lead to accidents and casualties. Repeatedly slamming the door with excessive force can damage the door and body, reduce the sound insulation performance of the door, increase driving noise, loosen the hinges and limiters between the door and body, cause permanent deformation of the door, and negatively affect the normal operation of the power window regulator and audio system due to strong vibrations. The potential hazards of slamming doors are severe.

What does 'New Energy off' mean?

New Energy off is the button to turn off the vehicle stability control system. Button introduction: New Energy off is the button to turn off the vehicle stability control system. This system is turned on by default, and can be turned off by long pressing this button. Introduction to new energy vehicles: New energy vehicles use unconventional vehicle fuels as power sources (or adopt conventional vehicle fuels and new vehicle power devices), integrate advanced vehicle power control and driving technologies, and form advanced technical principles, new technologies and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles and other new energy vehicles. Pure electric vehicles are vehicles that use on-board power as the power source, drive the wheels with motors, and meet the requirements of road traffic and safety regulations. Because their impact on the environment is smaller than that of traditional vehicles, their prospects are generally optimistic, but the current technology is not yet mature.
