What is the Difference Between a Limited-Slip Differential and a Differential Lock?

Here are the differences between a limited-slip differential and a differential lock: 1. Different functions. The differential lock locks the mechanism 100%, while limited-slip allows a certain degree of differential response; 2. Different applications. Differential locks are mostly used for off-roading and climbing, while limited-slip differentials are commonly used in racing (such as touring car races and WRC), though some off-road vehicles also use LSD (e.g., Dakar), and racing cars may use LOCK (for extreme drifting). The differences between a rear axle limited-slip differential and a differential lock are as follows: 1. The rear axle limited-slip differential is located between the two rear wheels of the vehicle. It compensates for the drawback of a standard differential spinning freely due to wheel suspension, where the differential provides a steady power flow to the spinning wheel without resistance, causing the vehicle not only to fail to move forward but also to lose a significant amount of power; 2. The significance of a limited-slip differential for performance improvement. When driving a car equipped with a limited-slip differential, if one of the drive wheels spins freely, the limited-slip differential will control the power output to both wheels, preventing the spinning wheel from continuing to spin and ensuring the other wheel has sufficient power to help the vehicle move forward; 3. The rear axle differential lock is located between the two front wheels of the vehicle. The differential lock and the differential serve completely opposite purposes. The significance of the rear axle differential lock for vehicle performance enhancement lies in improving off-road capability and enhancing the vehicle's ability to escape difficult situations when driving on unpaved roads.

How to Identify the Front and Back Sides of a Vehicle Air Filter?

There is an arrow indicator on the side of the car air filter, and the direction of the arrow indicates the direction of air flow. Generally, the arrow should face downward during installation. Precautions for the installation and use of the air filter are as follows: 1. During installation, whether the air filter is connected to the engine intake pipe via flange, rubber hose, or direct connection, it must be tightly secured to prevent air leakage. Rubber gaskets must be installed on both end faces of the filter. The wing nuts fixing the outer cover of the air filter should not be over-tightened to avoid damaging the paper filter element. 2. During use, the paper filter element must be strictly protected from being soaked by rainwater, as excessive water absorption will significantly increase intake resistance and shorten its service life. Additionally, the paper filter element must not come into contact with oil or fire.

Can I Transfer My Old License Plate to a New Car?

According to relevant laws and regulations, when the old vehicle's license plate has completed the motor vehicle transfer or cancellation registration, it can be used on a new car. More details about using old plates on new cars are as follows: 1. Generally, the following conditions must be met to use an old license plate on a new car: 1. The old license plate must have been used for more than three years. 2. The new car must apply for the old license plate within six months after the transfer or registration of the vehicle. 3. All traffic violation records of the old vehicle must be cleared. 2. After the old license plate is canceled, the traffic management department will retain the old license plate for the owner for six months. During this period, the owner can apply to the vehicle management office to continue using the old license plate. After the six-month period, the old license plate will automatically return to the database and can no longer be used.

Why Can't the Truck Start Despite Having Electricity and Fuel?

When encountering a situation where the vehicle has electricity and fuel but cannot start, it can be analyzed from the following two dimensions: 1. First, check whether the battery has power. If there is no power, it needs to be replaced in time. 2. Check whether the gear is in the P position. When igniting, ensure the gear is in the P position. If the vehicle can ignite in D or R gear, the sudden movement of the vehicle during ignition is undoubtedly a significant safety hazard, so extra attention is required. 3. The battery is one of the most likely causes of failure to start. In many cases, the battery suddenly loses power due to the end of its lifespan or the headlights being left on for a long time.

What type of engine oil is best for the Mazda CX-5?

Mazda CX-5 generally performs best with Mobil 5W-40 full synthetic engine oil. Mazda has not officially specified which type of oil to use for the CX-5, as long as it is genuine. Below are some relevant details: 1. The choice of engine oil should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher demands. 2. Multi-grade oil is recommended due to its cost-effectiveness, long lifespan, and high efficiency, providing better protection for the engine. Given the characteristics of multi-grade oil, it may appear darker or show lower oil pressure compared to conventional oil during use, which is normal. 3. If the engine is in good condition and the seasonal temperature is low, using lower-viscosity oil is advisable to ensure smooth oil flow. In high-temperature seasons or when the engine is severely worn, higher-viscosity oil helps form a protective oil film and reduces engine wear.

Can a Roof Wrap Pass the Annual Vehicle Inspection?

Applying a roof wrap that does not alter the vehicle's color will not affect the inspection, but if it changes the color, the vehicle will fail the annual inspection. Additional information about roof wraps is as follows: 1. If the color change is not approved by the traffic management department, the vehicle will not pass the annual inspection. According to the relevant provisions of the current "Motor Vehicle Registration Regulations," any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, including replacing the frame, body, or engine, must be reported to the vehicle management office for registration modification. Installing spoilers, extensive body kits, or modifying exhaust pipes are generally not permitted. 2. Applying a roof wrap under specified conditions is not illegal. Most vehicle owners use wraps for purposes such as heat insulation, privacy protection, and aesthetic enhancement.
