In vehicles, the letter R represents the reverse gear, whether it's a manual transmission or an automatic transmission. Automatic transmissions typically have four main gears: P, R, N, and D, which stand for Park, Reverse, Neutral, and Drive, respectively. Some automatic transmissions also include an S gear and an L gear, where S stands for Sport mode and L stands for Low gear. The reverse gear, fully known as the Reverse Driving Gear, is labeled as R on the gear console. Its purpose is to enable the vehicle to move backward, serving as a special driving gear. When the driver shifts the gear lever to the reverse position, the direction of the power input from the engine remains unchanged, while the internal reverse output gear of the transmission engages with the output shaft, causing the output shaft to rotate in the opposite direction. This, in turn, drives the wheels to rotate in reverse for backing up the vehicle.

What are the reasons for a vehicle stalling after starting?

Reasons for a vehicle stalling after starting: 1. Triggering the vehicle's anti-theft system: When the anti-theft system is activated, the engine automatically locks. Even if it can start, it cannot run, and the anti-theft light will illuminate. This is often caused by the owner using a non-chip key that the system cannot recognize. 2. Ignition switch failure: Poor contact of internal contacts in the ignition switch can cause the dashboard battery light, oil light, and engine fault light to not illuminate. 3. Low fuel system pressure: When the fuel system pressure is too low, the normal injection time delivers too little gasoline, resulting in a mixture that cannot be compressed and ignited. However, during startup, the extended injection time corrected by the startup program allows the gasoline to be compressed and ignited despite the low pressure. Once the vehicle starts and returns to normal injection, it stalls.

Can a Car with a Spare Tire Drive on the Highway?

Can a Car with a Spare Tire Drive on the Highway? A car with a spare tire can drive on the highway. Spare tires for cars are divided into full-size spare tires and non-full-size spare tires. Full-size spare tires have no restrictions on mileage or speed and can replace any temporarily or permanently unusable tire. Non-full-size spare tires can only be used on non-driving wheels, and the maximum speed must not exceed 80 kilometers per hour. Since spare tires are not frequently used, they should be regularly removed to check for insufficient tire pressure or other signs of wear. If small cracks are found on the sidewall of the spare tire, it should be replaced with a new one. In the storage area for the spare tire in the car, avoid placing oil containers such as engine oil or brake fluid, as leakage of these oils can corrode the tire and reduce its lifespan.

Are China V and China VI Engine Oils Interchangeable?

China V and China VI engine oils are not interchangeable. The difference lies in the higher grade requirements for engine oil, necessitating the use of fully synthetic oils of SN or SP grade. In the latest China VI engine oils, some manufacturers have reduced the proportion of sulfur, phosphorus, and other additives to minimize pollutant generation, making them more environmentally friendly without compromising combustion efficiency. Differences between China V and China VI: The China VI standard is stricter than China V. In terms of emission standards, nitrogen oxides are reduced by 77%, and particulate matter by 67%, with more stringent limits on particle number introduced. China VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. During the initial China V phase, emission standards varied between diesel and gasoline engine vehicles. In terms of pricing, China VI vehicles are more expensive than China V vehicles. Automakers also incur additional costs from various tests for vehicle certification and production commencement. China VI imposes stricter compliance supervision and management requirements, including type inspection and information disclosure, production consistency checks, new vehicle inspections, and in-use vehicle conformity checks for private cars, simplifying the method for determining standard compliance.

Why does the driver's license still show as pending on 12123 after the annual inspection?

After the annual inspection of the driver's license, it still shows as pending on 12123 because the staff have not yet entered the inspection information into the online system. As long as the inspection procedures are correct, it will not affect the use of the driver's license. Below are the details regarding the driver's license annual inspection: 1. Renewal time: According to the Road Traffic Safety Law implemented on May 1, the minimum validity period of a driver's license is 6 years, and the license does not require annual inspection during its validity period. However, the renewal should be processed at the local traffic police branch within 90 days before the expiration date. 2. Medical examination: Drivers aged 60 and above, regardless of the type of license they hold, must collect the "Motor Vehicle Driver's License Application Form" from the Vehicle Management Section of their local traffic police branch during the original annual inspection period. After undergoing a medical examination at a designated hospital, they must submit the form back to the Vehicle Management Section for computer confirmation.

What materials are needed for the first car maintenance?

The items required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle purchase invoice, and you need to go to the designated first maintenance institution for the service. Note: Make an appointment with the 4S store in advance. The first maintenance refers to the initial service after a new car is driven, and the specific time varies by car, usually after driving 1,000 to 3,000 kilometers. The car needs to participate in the first maintenance in time, neither in advance nor delayed. The completion of the first maintenance marks the end of the car's running-in period, and the car can now be driven according to the standard load and normal speed required by the vehicle. The time for the first insurance is calculated based on the date of picking up the car. There are two indicator values for the first maintenance time: mileage and time. Whichever comes first will be the standard. The first maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking whether various oil levels are normal, checking whether the generator belt and wiper blades are damaged, checking whether the tire pressure is normal, and checking whether the tires are damaged or bulging. Time required: It takes about 2 hours to complete all the work. The most important part of the first maintenance for a new car is changing the engine oil and oil filter. When changing the engine oil, the oil filter must be replaced together, and the selection of engine oil must refer to the "Vehicle Use and Maintenance Manual," as different models have different specified engine oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people will tidy up and clean their cars during holidays, washing the body with water and wiping it with a cloth. Here, it is important to remind that the interior of the car body does not need to be washed directly with water. If the floor mats are dirty, you can use a vacuum cleaner or take them out, brush them with detergent, dry them, and then put them back. There are many through holes under the rubber mats on the floor of the driver's cab. If water enters, it will not dry but will flow through the holes to parts like the gearbox, causing erosion and corrosion. The better approach is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is insufficient, it is recommended to drain the antifreeze early and add the same brand of antifreeze from the beginning. Because different brands of antifreeze have different chemical functions, the various functional additives may corrode each other. Different brands of antifreeze use different additives, so do not mix them to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When the bolts on a running car rust, they are usually oiled to make them work properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricating oil to them, but this brings necessary risks to safe driving. When the car is driving at high speed, the bolts and nuts may loosen or even fall off, leading to driving failure. When promoting an EFI car, there is no need to step on the accelerator: The promoter of an EFI car is different from that of an ordinary car. Its fuel injection control device can actively adjust the fuel supply according to the temperature and working conditions of the promoter, making the promoter work smoothly.
