Where should the jack be placed when changing a tire?

When changing a tire, the jack should be placed on the raised position of the side rail near the tire being replaced. This raised edge usually has two layers, and the grooved end of the jack should fit securely into it. Before lifting, it's best to loosen the nuts of the tire to be removed by one turn before raising the car. Steps for replacing a spare tire: First, loosen the wheel hub nuts but do not remove them. Then place the jack under the car at the corresponding position. Use the crank to turn the jack's bearing and lift the car. Then remove the wheel hub nuts, install the spare tire, and tighten the nuts (note that the nuts cannot be fully tightened until the car is lowered back to the ground). Finally, lower the car to the ground, remove the jack, and fully tighten the nuts. The car jack is stored in the car's toolbox and is used to lift the car body when changing a spare tire. There are several types of car jacks, including pneumatic jacks, electric jacks, hydraulic jacks, and mechanical jacks, with hydraulic and mechanical jacks being the most commonly used. Car jacks are essential for changing spare tires, making it convenient to replace a flat tire when you're on the road.

Do Hybrid Cars Need to Install a Charging Pile for Charging?

Hybrid cars do need to install a charging pile. Charging piles are convenient and fast, and plug-in hybrid electric vehicles (PHEVs) must frequently maintain sufficient battery charge to leverage their advantages. Since plug-in hybrid vehicles have relatively small power battery capacities, they cannot utilize fast charging. Instead, they rely on slow charging, which takes a longer time—typically around 3 to 10 hours to fully charge. Given the lengthy charging duration, relying solely on public charging stations is inconvenient, making home charging conditions crucial. While portable chargers can also be used to charge PHEVs at home, their 1.7KW charging power is too low, resulting in excessively long charging times. Therefore, installing a 3.3KW wall-mounted charging pile is recommended for convenience. In hybrid mode, the motor of a plug-in hybrid vehicle can also assist the engine by providing supplementary power, thereby reducing engine speed and lowering fuel consumption. When the battery charge is insufficient or falls below the SOC (State of Charge) value, the engine will allocate some power to drive the generator and recharge the battery. However, since the engine's speed increases during power generation, and energy loss occurs when converting fuel to electricity—combined with the heavier curb weight of PHEVs compared to conventional fuel-powered cars—this scenario leads to higher fuel consumption, which is not conducive to energy savings and emission reduction.

Is it necessary to replace the rear axle rubber bushings?

It is necessary to replace the rear axle rubber bushings. Although there is no fixed replacement interval for rear axle rubber bushings, they should be replaced when damaged or aged. Worn-out rear axle rubber bushings will fail to provide shock absorption, causing chassis vibration and abnormal noises. Severe vibration may affect driving stability and compromise ride comfort. The rear axle rubber bushing serves as a flexible connecting buffer sleeve between the shaft and housing. Damaged bushings may lead to collisions between shaft components and could potentially cause misalignment between rear wheels and wheel arches, resulting in abnormal tire wear. Replacement method for rear axle rubber bushings: After lifting the vehicle, remove the two rear axle screws and oil pipes. Then use specialized tools for rear axle bushings to extract the old bushing. Apply lubricating grease to the new bushing before installing it. The rear axle refers to the components of the rear drive shaft that transmits power. It consists of two half-axles that can perform differential movement. The rear axle also functions as a device to support and connect the rear wheels. For front-wheel-drive vehicles, the rear axle acts as a trailing axle, serving only a load-bearing purpose. For vehicles where the front axle is not the drive axle, the rear axle becomes the drive axle, performing not only load-bearing functions but also driving, speed reduction, and differential functions.

What is the method to determine a 30 cm distance between the car body and the roadside?

Methods to determine a 30 cm distance between the car body and the roadside include observing the position of the wiper protrusion and checking in the rearview mirror whether the rear door handle aligns with the sideline. In driving license tests, many scenarios require the distance between the car body and the sideline to be within 30 cm. When parking by the roadside, it is essential to carefully observe the parking space and check for any obstacles in front or behind. In areas with heavy traffic, drivers should always check the rearview mirror for approaching vehicles before opening the door to exit, to prevent collisions. Methods to maintain a 30 cm distance between the car body and the roadside: 1. Observe the position of the wiper protrusion: The wiper is a standard feature on every car, and its protruding part is easily noticeable when flat. During driving tests, you can determine the distance between the car and the sideline by checking if the wiper protrusion aligns with the right sideline. When they align, the distance is exactly 30 cm. 2. Check the rear door handle in the rearview mirror: During tests, when the position of the rear door handle reflected in the rearview mirror aligns with the sideline, the distance between the car and the sideline is exactly 30 cm.

How to Reinspect a Vehicle That Has Not Been Inspected for Three Years?

The vehicle owner needs to personally submit a written application for reinspection to the traffic police department. Required documents include the vehicle license, third-party liability insurance certificate, and the original and copies of the vehicle and vessel tax. During the reinspection, fines must be paid, and 3 points will be deducted from the driver's license. According to the Road Traffic Law, vehicles that have not undergone the mandatory safety technical inspection (annual inspection) on time are not allowed to be driven on the road. Violators will be fined and have 3 points deducted from their license. In case of any traffic accident caused by the failure to undergo the annual inspection, the party involved will bear full or primary responsibility. Moreover, driving without inspection is considered illegal, and insurance will not cover any claims. The "Road Traffic Safety Law Implementation Regulations" stipulate: Article 16: Motor vehicles must undergo safety technical inspections according to the following intervals from the date of registration: passenger vehicles for commercial use must be inspected once a year within 5 years; after 5 years, once every 6 months; trucks and large or medium-sized non-commercial passenger vehicles must be inspected once a year within 10 years; after 10 years, once every 6 months. Required documents: ID card, vehicle license, compulsory traffic insurance policy, vehicle and vessel tax invoice (it's advisable to bring all relevant materials in case they are needed). The inspection must be conducted within the validity period of the compulsory traffic insurance. If the insurance has expired, it should be renewed before the inspection. All violations must be cleared. Essential items like a fire extinguisher and warning triangle are mandatory. Ensure that lights, brakes, etc., are functioning properly. The vehicle's appearance, including color and logos, must match the registration details. Owners with modifications are advised to remove them before the inspection.
