The differences between brake fluid and engine oil are: 1. Different functions: Engine oil can lubricate and reduce wear, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks in the engine. It is known as the "blood" of a car. Brake fluid, on the other hand, is a liquid medium used in hydraulic braking systems to transmit braking pressure. It is used in vehicles with hydraulic braking systems. Brake fluid, also known as braking oil or force oil, is an indispensable part of the braking system. 2. Different compositions: The main component of brake fluid is ethylene glycol, which has a slight alcohol-like smell, with alcohol being composed of ethanol. Engine oil, however, consists of base oil and additives.

What Does Parallel Import Car Mean?

Parallel import cars are vehicles imported directly from their country of origin, generally referring to cars imported directly from the original production location by importers other than the general distributor. Parallel import cars are also legal products and enter the domestic market after passing 3C certification. Advantages of parallel import cars: 1. Model and delivery time advantages: Parallel import cars are freely purchased overseas and then shipped to China for sale, saving a significant portion of the waiting time for new cars; 2. More diverse model configurations; 3. Availability of multiple luxury sports cars; 4. Original factory modified models; 5. Optimized delivery process: Except for overseas new cars that have not yet entered the domestic market, most models can be picked up immediately after completing the corresponding procedures.

How Often Should You Refill the Diesel Exhaust Fluid?

Diesel exhaust fluid (DEF) typically needs to be refilled every 2,000 kilometers. Consequences of not using DEF include: 1. Exceeding emission standards, causing environmental pollution; 2. Oxidation of chemicals in the vehicle's system, leading to clogged DEF injectors and potential system failure; 3. Reduced vehicle power. The purpose of DEF is to reduce nitrogen oxide emissions from vehicle exhaust, lower pollution, and improve environmental performance. Reasons for DEF warning light activation: 1. Low DEF pressure or high consumption; 2. Insufficient power due to excessively high or low DEF consumption; 3. Instrument cluster malfunction. Methods to resolve DEF warning light: 1. Replace DEF solution; 2. Replace water heating valve; 3. Replace DEF pump and power module connector.

What are the differences between SUVs and off-road vehicles?

The differences between SUVs and off-road vehicles are: 1. Different body structures: SUVs use unibody construction; off-road vehicles use body-on-frame construction. 2. Different four-wheel drive systems: Most SUVs use electric four-wheel drive, with a few using part-time four-wheel drive; most off-road vehicles use mechanical four-wheel drive with differential locks. 3. Different engines: SUV engines are mostly high-revving engines; off-road vehicles mostly use low-revving, high-torque off-road engines. 4. Different suspensions: SUVs use four-wheel independent suspension or front independent plus rear semi-independent suspension; off-road vehicles use front solid axle plus rear solid axle or front independent suspension plus rear solid axle configurations.

Is It Necessary to Repair Scratched Rims?

It is necessary to repair scratched rims. Below are the methods for repairing scratched rims and the consequences of not repairing them: Methods for repairing scratched rims: Clean the dirt from the scratched area to avoid mixing impurities during the painting process. If the scratch is deep, use a sharp tool to clean it. To minimize damage to the tire surface, apply a professional cleaning agent to the scratched area. Finally, use a filler to level the surface, and once it dries, repaint the area. Consequences of not repairing scratched rims: Leaving scratched rims unrepaired will affect the vehicle's appearance. Additionally, unrepaired rims can impact the vehicle's performance. As the internal support structure of the tire, rims are typically very sturdy. However, once damaged, they indicate significant friction has occurred. Failing to repair them can cause severe damage to the alloy components and even affect the vehicle's stability.

What are the reasons for a car suddenly stalling during normal operation and failing to restart?

Car suddenly stalling during normal operation and failing to restart can be caused by: 1. Short circuit in the positive terminal of the power system to ground; 2. Short circuit in the starter control circuit; 3. Fault in the starter itself; 4. No control voltage in the starter signal line; 5. Internal fault in psf1. The starter converts the electrical energy from the battery into mechanical energy, driving the engine flywheel to rotate and enabling the engine to start. The cylindrical component on the starter is the solenoid, which functions to push the gear forward, engaging the starter gear with the engine's flywheel. The lower cylindrical component is the starter motor, responsible for providing the torque needed to start the engine.
