Pressure lubrication refers to adding an oil pump to the engine, which uses the pressure of the oil pump to forcibly supply oil to various components. More related information is as follows: 1. Pressure lubrication is a type of forced lubrication, mainly relying on the pressure generated by the oil pump to deliver lubricating oil. It is primarily used for lubricating heavily loaded friction surfaces such as main bearings, connecting rod bearings, and camshaft bearings. 2. The function of pressure lubrication is to alter product performance. Improved lubrication can reduce the temperature between components, which helps enhance the toughness of the product. Currently, there are three types of lubrication systems used in automobiles: pressure lubrication, splash lubrication, and composite lubrication.

Pressure lubrication is a critical system in automotive engines, where the oil pump pressurizes and forcibly delivers oil to moving components like crankshaft bearings and camshafts, reducing friction and wear. Unlike splash lubrication that relies solely on parts flinging oil, pressure lubrication ensures uniform oil coverage across all components, maintaining effective lubrication during high-speed operation or heavy loads. From my experience, if oil pressure drops, the dashboard warning light will illuminate—promptly pull over for inspection rather than continuing to drive, as engine seizure could occur. For routine maintenance, using high-quality oil and regularly replacing the oil filter prevents oil passage blockages or pump failures, extending engine life by at least five years.

Having driven for decades, I believe pressure lubrication is the lifeline of modern engines. The oil is pressurized by the pump and delivered to every corner, far more reliable than the old splash lubrication, especially during uphill climbs or long-distance driving, as it maintains temperature balance. For maintenance, I frequently check the dipstick to ensure the oil level is appropriate; if the oil pressure warning light comes on, it's time to replace the oil and filter. Don't overlook the small details—failure of pressure lubrication can lead to excessive wear and ultimately engine failure. I learned this the hard way when I was younger, and now regular maintenance keeps my car running smoothly.

Can a car still be driven after 12 years?

A car that has been used for 12 years can theoretically continue to be used as long as it is not damaged. New regulations implemented: Since May 1, 2013, the new regulations for phasing out and scrapping old vehicles have been implemented, with the scrapping age limit for private cars abolished and a mandatory scrapping at a maximum mileage of 600,000 kilometers. The regulations state that small and micro non-operational passenger vehicles, large non-operational cars, and wheeled special machinery vehicles have no usage age limit. The new regulations for the scrapping age of household cars, as officially issued by the Ministry of Commerce in the "Mandatory Scrapping Standards for Motor Vehicles," abolish the mileage age limit for non-operational cars and set the mileage limit for private car scrapping at 600,000 kilometers. Strict regulations: This method of abolishing the age limit and instead using mileage as the standard greatly improves the utilization rate of cars. Calculating based on a normal annual usage of 20,000 kilometers, the usage period of private cars is almost doubled. Although the age limit is abolished, it does not mean that any vehicle can truly reach 600,000 kilometers. The new policy has imposed stricter regulations on vehicle usage standards.

What is the displacement of the Fista?

Here is the relevant introduction about the displacement of the Fista car: 1. The displacement of the Fista car is 1.4 liters or 1.6 liters. 2. The Fista uses two engines in total, one is a 1.4-liter turbocharged engine, and the other is a 1.6-liter turbocharged engine. Below is the relevant introduction of the 1.4-liter and 1.6-liter turbocharged engines: 1. 1.4-liter turbocharged engine: (1) 140 horsepower and 242 Nm of maximum torque. (2) The maximum power speed is 6000 revolutions per minute. (3) The maximum torque speed is 1500 to 3200 revolutions per minute. (4) This engine is equipped with direct injection technology and uses an aluminum alloy cylinder head and block. 2. 1.6-liter turbocharged engine: (1) 204 horsepower and 265 Nm of maximum torque. (2) The maximum power speed is 6000 revolutions per minute. (3) The maximum torque speed is 1500 to 4500 revolutions per minute. (4) The engine is equipped with direct injection technology and uses an aluminum alloy cylinder head and block.

What is the reason for the car fan not rotating at low speed but rotating at high speed?

Car fan not rotating at low speed but rotating at high speed may be due to a damaged thermostat, abnormal circulation of the vehicle's cooling system, causing the temperature control switch to malfunction, which can also lead to this situation. The last possible cause is a faulty engine coolant temperature sensor. Below are additional details: Principle: When the coolant temperature is below 70 degrees, the thermostat remains closed. At this point, the engine's cooling system only has a small circulation loop, without a large circulation loop. This means the water from the engine's outlet pipe passes through a small bypass pipe directly into the cylinder head for internal circulation. Specific reasons: At this stage, the coolant does not pass through the radiator. As the temperature continues to rise to nearly 80 degrees, the thermostat gradually opens until it is fully open. Then, the engine's coolant flows through the main outlet pipe to the radiator before entering the cylinder head for large circulation. If the engine temperature continues to rise, the temperature-sensitive switch installed on the thermostat cover or radiator will activate the fan's low-speed switch, causing the fan to rotate at low speed and draw air from front to back for cooling.

Is it okay to shift gears without pressing the clutch?

Shifting gears without pressing the clutch can have negative effects on the car. Failure to fully depress the clutch can result in difficulty engaging gears and gear grinding. The more frequently this occurs, the more severe the gear wear becomes. Over time, it may lead to the inability to engage gears or gears slipping out of place easily. Correct clutch usage methods: 1. Proper clutch pedal posture. When pressing the clutch pedal, use the ball of your foot on the pedal with your heel touching the ground. When the clutch is fully depressed, keep your knees slightly bent. 2. Depress the clutch pedal fully. Avoid keeping the clutch engaged for prolonged periods to ensure complete separation and prevent wear. 3. Control the timing of clutch release. When driving, do not release the clutch too quickly or deliberately raise the engine RPM too high, as this accelerates clutch wear. 4. Fully depress the clutch pedal before shifting gears. 5. When pressing the clutch pedal, quickly release the accelerator pedal. 6. Coordinate clutch operation with gear shifting. If the gear does not engage smoothly, release the clutch first, then press it again before shifting. Never force a gear shift, as this can cause gear friction and damage the transmission. 7. Avoid resting your left foot on the clutch pedal while driving. 8. Never use your right foot to press the clutch pedal under any circumstances while driving.

Can traffic violation points be deducted in a different location?

Traffic violation points can be deducted in a different location. If the party involved has no objection to the facts of the traffic violation, they can choose to handle the matter not only at the location where the violation occurred but also at any other local public security traffic management department outside the violation location. Below is additional information: Legal Basis: Article 4 of the "Procedural Regulations for Handling Road Traffic Safety Violations" stipulates that violations discovered by traffic police during duty enforcement shall be under the jurisdiction of the traffic management department of the public security organ at the location where the violation occurred. In case of disputes over jurisdiction, the matter shall be reported to the common higher-level traffic management department of the public security organ for designation of jurisdiction. The higher-level traffic management department of the public security organ shall promptly determine the jurisdictional authority and notify all disputing parties. Relevant Regulations: Violations recorded by traffic technical monitoring data may be under the jurisdiction of the traffic management department of the public security organ at the location where the violation occurred, where it was discovered, or where the motor vehicle is registered. If the violator or the owner/manager of the motor vehicle disputes the facts of the violation recorded by traffic technical monitoring data, they shall raise the objection to the traffic management department of the public security organ at the location where the violation occurred, which shall handle the matter according to the law.

Should water be added when filling the car with windshield washer fluid?

Water should be added when filling the car with windshield washer fluid. After dilution, the windshield washer fluid can be directly poured into the vehicle's windshield washer reservoir for immediate use. Automotive windshield washer fluid is widely used for quick cleaning and brightening of various glass surfaces, including car windshields, rearview mirrors, as well as household glass, office glass, door and window glass, and decorative glass. It offers comprehensive performance, is easy to use, and can even be homemade. Below are some related details about windshield washer fluid: 1. Windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Due to the commonality of its production process and materials, there are some inferior products on the market. When purchasing, shake the bottle vigorously a few times; the more foam there is, the more surfactants it contains. Moreover, the finer the foam, the more environmentally friendly the anionic surfactants are. If the foam is overly expansive, the environmental friendliness is poorer. 2. The thicker the windshield washer fluid, the more active ingredients it contains. Generally, you can turn the bottle upside down to observe the speed of the bubbles rising inside; slower speed indicates higher viscosity. High-quality windshield washer fluid usually has no odor, while inferior products may have a strong chemical smell, and an unpleasant odor may develop if stored for too long. You can smell it when purchasing.
