What are the components of an engine lubrication system?

The engine lubrication system consists of an oil pump, pressure regulating valve, oil pickup, oil filter, oil cooler, oil pressure sensor, nozzles, oil passages, and crankcase ventilation filter. The function of the lubrication system is to continuously deliver an adequate amount of clean oil at the appropriate temperature to all moving parts' friction surfaces during engine operation, forming an oil film between these surfaces to achieve liquid friction. This reduces friction resistance, lowers power consumption, and minimizes component wear, thereby enhancing the engine's operational reliability and durability. Below is the classification of lubrication methods: 1. Pressure lubrication: This method supplies oil to friction surfaces under a certain pressure and is primarily used for lubricating heavily loaded surfaces such as main bearings, connecting rod bearings, and camshaft bearings. 2. Splash lubrication: This method utilizes oil droplets or mist splashed by moving parts during engine operation to lubricate friction surfaces. It is mainly used for lubricating lightly loaded surfaces such as cylinder walls, camshafts, lifters, valve stems, and rocker arms in the valve train. 3. Grease lubrication: This involves periodically applying grease through grease fittings to lubricate working surfaces of components like water pump and generator bearings.

What Causes the Navigation Central Control Screen to Go Black?

It may be due to poor line contact, so it's necessary to promptly check whether there is a loose connection in the circuit. A loose connection naturally leads to a black screen on the central control display, and the issue can be resolved by properly reconnecting the loose parts. It could also be caused by aging of the power signal line. Trying to replace it with a new one might solve the black screen problem, indicating that the power signal line was indeed faulty. Other reasons for the navigation central control screen going black include: 1. Prolonged Use: If after checking for loose connections and aging signal lines the central control screen still doesn't light up, it's likely due to prolonged use causing a failure in the power supply module. This not only results in lag but can also lead to a black screen in severe cases. 2. Design Flaws: It may also be caused by defects in the circuit design. Issues like module abnormalities and design flaws are beyond the scope of DIY fixes and require inspection, repair, or replacement at a repair shop.

Should You Use Turn Signals When Making a U-Turn?

When making a U-turn, you need to turn on the turn signal. If you are making a U-turn from the left lane, use the left turn signal; if you are making a U-turn from the right lane, use the right turn signal. Precautions for making a U-turn: When making a U-turn, you should turn on the left turn signal in advance. The maximum speed should not exceed 30 km/h, and you must not obstruct other vehicles or pedestrians traveling normally. Conditions under which U-turns are allowed: Presence of a U-turn signal or sign: If there is a U-turn signal at an intersection, you can make a U-turn when the U-turn indicator is green. If there is a U-turn sign at the intersection or a U-turn indicator on the lane, you can make a U-turn while ensuring your own and others' safety. No U-turn sign but left turns are allowed (no prohibition of U-turn signs): At intersections where left turns are allowed and there are no signs or markings prohibiting U-turns, vehicles can make a U-turn. Note that the vehicle must proceed according to the left-turn signal without affecting the normal travel of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, you can first enter the left-turn waiting area when the straight signal is green and wait until the left-turn signal turns green to make the U-turn. U-turns are allowed at dashed lines: U-turns are permitted at both white and yellow dashed lines. If it is a double yellow line with one solid and one dashed, check whether your side is the dashed line. If it is, you can make a U-turn safely; if it is solid, you cannot. If encountering a double yellow line at an intersection, you can make a U-turn on the dashed side, but you must not cross the stop line ahead. U-turns are allowed at yellow grid lines: Parking is prohibited in yellow grid areas, but as long as there is no central barrier, you can make a U-turn here after yielding to normally traveling vehicles. U-turns are allowed on the dashed side of a green belt: When the front of the green belt is a dashed line, vehicles on that side can make a U-turn from there. When the front of the green belt is a solid line, vehicles must follow the traffic signal, cross the zebra crossing, and then make a U-turn. Driving over solid lines or zebra crossings to make a U-turn is prohibited.

Where is the car engine number located?

The engine number can be found on the outer surface of the engine block, on the vehicle's nameplate, or on the nameplate inside the engine compartment. You can also check the engine number on the car purchase invoice, the factory certificate, the operating license for commercial vehicles, the vehicle purchase tax payment certificate, the registration record with the public security authorities, or the vehicle insurance card. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number is like a person's ID number, representing each vehicle and storing very important information about the car. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to indicate information such as the manufacturer, specifications, performance, features, technology, purpose, and batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are all marked with the professional manufacturer's name, model, and production number as required. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's range, and engine models can be the same. The engine number, however, refers to the production number of the engine, and each engine can only have one unique engine number. Composition of the car engine number: Front part: Includes the product series code, generation symbol, and regional or corporate code. Manufacturers can choose the appropriate letters as needed, but they must be approved and filed by the industry standard's regulatory body. Middle part: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear part: Composed of symbols for structural features and usage characteristics. Tail part: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol. The rear and tail parts can be separated by a hyphen (-).

What does 94V on tires mean?

Tire 94V refers to the load index and speed rating of the tire. The number 94 indicates the load index for a single tire, representing a maximum load capacity of 670 kilograms. The higher the number, the stronger the tire's load-bearing capacity. The letter V denotes the speed rating, indicating that the tire can withstand speeds of up to 240 kilometers per hour. Car tires are one of the essential components of a vehicle, as they directly contact the road surface and work together with the suspension system to absorb shocks during driving. This ensures good ride comfort and smooth driving, maintains excellent traction between the wheels and the road, and enhances the vehicle's traction, braking, and off-road performance.

What to Do If You Can't Find Your Car?

Here are several methods to locate your car: 1. Press the unlock button on the key: Determine the approximate location of the car through the hazard lights or unlocking sound. If the car is parked in a large shopping mall, you can use the intelligent car-finding system by entering your license plate number on the screen, which will display your current location and the car's parking position, along with the optimal route to retrieve it. 2. Mobile phone positioning: Open the car-finding app to locate your car. Some GPS systems also allow you to check the car's location via WeChat official accounts by following the on-screen instructions and sending a character code to receive the location information. 3. Client-side car search: Download and install the GPS vehicle monitoring system on your computer to query the car's location information in real-time.
