Is the Corolla's Engine Imported?

Toyota Corolla's engine is assembled by Tianjin FAW Toyota Engine Co., Ltd., with technology provided by Toyota. Therefore, this engine is domestically produced. The engine models used in the Toyota Corolla are 9NR/8NR, with a maximum horsepower of 116 HP, a maximum power output of 85 KW, a maximum power speed range of 5200-5600 rpm, and a peak torque of 185 N.m. For daily maintenance of the Toyota Corolla's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, performance degradation can cause various engine issues. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the relief valve, carrying contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush the radiator. Removing rust and scale not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

How to Identify Michelin Run-Flat Tires?

Michelin run-flat tires are marked with ZP. If the tire is labeled with ZP, it is a run-flat tire. Here is more information about run-flat tires: 1. Components of run-flat tires: They consist of an outer tire, a common inner tube, a spare inner tube, a steel rim, a gas generator, a pressure sensor, and a control unit. 2. The main differences between run-flat tires and ordinary tires: Run-flat tires have a smaller aspect ratio, making the vehicle's overall center of gravity less prone to change during use. In contrast, ordinary tires have a larger aspect ratio, making them more likely to lose balance during severe bumps or collisions, and they are more prone to blowouts. Additionally, controlling the tire becomes more difficult after a blowout occurs.

What is the ideal tire pressure?

For most passenger cars, the recommended tire pressure is generally between 2.2-2.5 bar. According to the international GBT2978-2008 standard, the tire pressure requirements for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. When inflating tires, pay attention to the following points: Always use a pressure gauge to check the pressure to avoid overinflation, which can cause the tire to burst. After stopping, wait for the tires to cool down before inflating, as driving increases tire temperature, which affects pressure. Check the valve stem. If the valve stem and core are not properly aligned or have defects, it can make inflation and pressure measurement difficult. Ensure clean inflation. The air used should not contain moisture or oil, as this can damage the inner tube rubber. Do not exceed the standard pressure significantly and then deflate, nor overinflate after prolonged periods without inflation. Excessive pressure can overstretch the cords, reducing their strength and shortening tire life. Before inflating, clean the valve stem of dust and ensure the valve core is secure. After inflation, apply soapy water (or saliva) to the valve stem to check for leaks (bubbles indicate leaks). Always replace and tighten the valve cap to prevent dirt from entering. When inflating radial tires, their larger deflection and contact area may lead to misjudgment of underinflation and overinflation, or vice versa. Always use a standard pressure gauge for accurate measurement. Radial tires typically require 0.5-1.5 kg/cm2 higher pressure than conventional tires.

Is it necessary to depress the clutch when turning with a manual transmission car?

Whether to depress the clutch when turning with a manual transmission depends on the turning speed. For low-speed turns, you may not need to depress the clutch or use the semi-engaged clutch (half-clutch), while for high-speed turns, you should depress the clutch and downshift as needed. Below are the relevant details about manual transmission turning: 1. Low-speed conditions: When the vehicle is moving at a crawl or turning at a speed of 5~10 km/h, you should use the semi-engaged clutch or keep the clutch depressed to ensure the vehicle has sufficient power and does not stall. 2. High-speed conditions: When turning at speeds of 80 km/h or above, you should depress the clutch. At higher speeds, the vehicle has greater inertia, so the speed will not drop too low. Since the speed is higher, the gear will also be in a higher range, where traction is lower. If the turn is long and the vehicle's speed drops significantly, you can downshift appropriately to increase traction. After completing the turn, you can quickly accelerate the vehicle again.

How Many Liters of Windshield Washer Fluid Does a Car Need?

Car windshield washer fluid capacities vary by vehicle model, with most sedans holding around 3L. The usage method for car windshield washer fluid is as follows: 1. Spray the washer fluid on the area to be cleaned, let it soak for 2-3 minutes, then wipe with a soft cloth or directly apply the cleaning solution with a soft cloth until the surface becomes clear. 2. For heavy dirt, repeat the cleaning process, rinse with clean water, and then dry. 3. After dilution, the washer fluid can be directly poured into the vehicle's windshield washer reservoir for on-the-go spraying. The introduction to windshield washer fluid is as follows: 1. Windshield washer fluid, commonly known as car windshield cleaning fluid, is a consumable in automotive use. High-quality windshield washer fluid mainly consists of water, alcohol, glycol, corrosion inhibitors, and various surfactants. 2. Professional car windshield washer fluid is composed of water, alcohol, glycol, corrosion inhibitors, and multiple surfactants, featuring functions like dirt removal, antifreeze, antistatic, and corrosion prevention. Alcohol and glycol can significantly lower the liquid's freezing point, providing antifreeze effects and quickly dissolving frost.

What to Do If Your Driver's License Has Been Expired for Over a Year Without Renewal?

Solution for a driver's license that has been expired for over a year without renewal: The motor vehicle driver should bring the required materials to the vehicle management office where the driver's license was originally issued to apply for renewal. The vehicle management office will process the renewal within one working day upon approval. Required materials for renewal include two photocopies of ID card, two recent 1-inch color photos without a hat, original ID card, original driver's license, and a medical examination certificate from a county-level or above hospital. Renewal and inspection must meet the following conditions: Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses must have no points recorded in the current scoring cycle, or holders of other permitted vehicle-type driver's licenses must have less than 12 points recorded in the current scoring cycle; Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses who have points recorded in a scoring cycle, and holders of other permitted vehicle-type driver's licenses who have been involved in a traffic accident causing death and bear equal or greater responsibility without having their driver's license revoked, must have completed the inspection education; The applicant must have no pending road traffic safety violations or traffic accidents; The applicant's physical condition must meet the driving license requirements; The motor vehicle driver's license must not be under circumstances of being legally seized, detained, temporarily suspended, revoked, canceled, or annulled.
