What are the functions of an engine lubrication system?

The functions of an engine lubrication system include: 1. Lubrication: Engine oil forms an oil film between moving parts to reduce friction resistance, power loss, and component wear; 2. Cooling: The fluidity of engine oil carries away some of the heat from engine components, preventing overheating and damage; 3. Cleaning: Circulating engine oil removes metal particles generated during engine operation, dust absorbed from the atmosphere, and some solid substances produced by fuel combustion, preventing the formation of abrasives between parts that could accelerate wear; 4. Sealing: The viscosity of engine oil allows it to adhere to the surfaces of moving parts, improving sealing effectiveness and reducing gas leakage; 5. Rust prevention: The lubricating oil film adheres to metal surfaces, isolating air and water, thereby preventing rust and corrosion.

Is it useful to add gasoline additives to cars?

Adding gasoline additives to cars is useful. Gasoline additives can increase the octane number of gasoline, making it burn more completely and reducing carbon deposits. This helps maintain the engine's power and fuel consumption, preventing a decrease in engine power and an increase in fuel consumption due to excessive carbon deposits. There are four common types of additives on the market: 1. Cleaning type: suitable for cars with high mileage and older models; 2. Maintenance type: suitable for new cars; 3. Octane number adjustment type: suitable for areas where the gasoline quality is not very good; 4. Comprehensive type: suitable for all vehicles.

What to Do When the Brake Pedal is Hard to Press?

If the brake pedal is hard to press, it may be due to a leak or failure in the car's brake booster pump. Regular maintenance of the brake system is essential during normal vehicle use. Issues such as excessive impurities in the brake master cylinder, poor sealing, leakage in the brake master or wheel cylinders, failure of the vacuum booster pump, or overloading can all lead to brake failure. In addition to regular inspections and timely replacement of worn friction components, the brake system should also undergo proper periodic maintenance: 1. Clean the surfaces of brake friction components and their cooling channels with solvent-based cleaners; 2. Apply long-lasting protective agents to the rubber dust boots of the brake wheel cylinders and areas prone to rust; 3. Apply long-lasting lubricants to the contact surfaces between the tire rims and the car hubs; 4. Use high-temperature and impact-resistant lubricants on areas such as the back of the brake friction components and noise-damping shims.

Where are the fog lights on a Toyota Prado?

Toyota Prado front fog lights are located at the lowest part of the front bumper, while the rear fog lights are positioned on both left and right sides of the rear. The purpose of fog lights is to enhance vehicle visibility during foggy or rainy conditions when visibility is significantly reduced, allowing other drivers to see your vehicle. Therefore, fog lights require light sources with strong penetration capability. Most vehicles use halogen fog lights, while more advanced models may feature LED fog lights. In low-visibility conditions, fog lights should be activated in advance to warn approaching vehicles. Operation method: The fog light switch knob is located at the center of the light control stalk, and can be activated by simply rotating to the corresponding position.
