Is it necessary to replace the gasket when changing engine oil?

The gasket is a disposable component and can be damaged after tightening. Therefore, the drain plug gasket should be replaced when changing the engine oil. The introduction and function of the gasket are as follows: Introduction to the gasket: The gasket is the drain plug, and the drain hole is located at the bottom of the oil pan. If it is not replaced regularly, over time it may become stripped, which would necessitate replacing the entire oil pan. Function of the gasket: During engine operation, wear and tear between internal components generates many fine metal particles. However, ordinary oil filters cannot trap these metal shavings, which can be sucked into the oil passages by the oil pump, potentially causing blockages. Therefore, magnetic drain plugs are used. These magnetic drain plugs can attract and collect these metal particles at the bottom of the oil pan, thereby protecting the engine.

What is the passing score for manual transmission Subject 2?

The passing score for the C1 driver's license Subject 2 test is 80 points. The C1 Subject 2 test mainly consists of five items: reversing into a garage, parallel parking, curve driving, right-angle turning, and hill start and stop. For automatic transmission (C2), the hill start and stop is not included in Subject 2. A C1 driver's license allows the holder to drive small and micro passenger vehicles. C1 test consists of four subjects, with the other items as follows: Subject 1: Mainly tests basic knowledge of road traffic; Subject 3: Tests 16 driving skills, including preparation before driving, starting, straight-line driving, etc.; Subject 4: Tests safe and civilized driving requirements, similar to Subject 1, it is a theoretical test. Subject 2 test techniques: During the Subject 2 test, before driving, be sure to adjust the seat height and rearview mirrors to ensure a broad field of vision, and fasten the seat belt. During the test, do not stop unless the voice prompt indicates failure. For parallel parking, remember to find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the car's speed. For hill start, remember to pull the handbrake, turn on the left turn signal when starting, and release the handbrake. Keep the clutch steady, press the accelerator while releasing the clutch to avoid stalling or rolling back. For right-angle turning, find the reference point before turning and coordinate with the car's speed. For curve driving (S-curve), slow down. For reversing into a garage, control the speed, find the reference point, and make minor adjustments if there is any deviation observed in the rearview mirror. Subject 2 deduction items: Reversing into a garage: If the car body crosses the line, 100 points are deducted, and the test is failed; if the car is not fully parked in the garage, 100 points are deducted, and the test is failed; stopping midway deducts 5 points each time; failure to complete the test within the specified time deducts 100 points, and the test is failed. Parallel parking: If the car body crosses the line after stopping in the garage, 100 points are deducted, and the test is failed; stopping midway deducts 5 points each time; if the tires or car body touch the curb line while driving, 10 points are deducted; failure to complete the test within the specified time deducts 100 points, and the test is failed. Curve driving: If the wheels press the road edge line, the test is failed; stopping midway results in failure; driving in a gear lower than second deducts 5 points. Right-angle turning: If the wheels press the road edge line, the test is failed; stopping midway deducts 5 points each time. Hill start and stop: If the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line and exceeds 50 cm, the test is failed; exceeding the specified time for starting deducts 100 points, and the test is failed; if the front bumper or front axle is not aligned with the pole line but does not exceed 50 cm, 10 points are deducted; if the car body is more than 30 cm but less than 50 cm from the road edge line, 10 points are deducted; failure to tighten the parking brake deducts 10 points. C1 driver's license test passing standards: Traffic laws and related knowledge—90 points to pass. Field driving—80 points to pass. Road driving—80 points to pass. Safe and civilized driving knowledge—90 points to pass.

Should the motorcycle recorder be mounted on the helmet or the vehicle?

It depends on the type of recorder you purchase. If it has front and rear cameras, it can be fixed on the vehicle. If it is an action camera, it can be mounted on the helmet. Classification of motorcycle recorders: Motorcycle recorders come in two types: those powered by the vehicle's battery and those powered by the recorder's own battery. Placement options include fixing it on the vehicle or carrying it on the person. Connected to the battery or the vehicle's USB for power, fixed at the front of the vehicle, with separate memory card storage, it can operate for three to four hours without a power source, automatically starting the recording function when the motorcycle is started. The camera is placed inside the vehicle, such as under the base, with two camera lines fixed at the front and rear of the vehicle, separately storing data on a memory card, and automatically starting the recording function when the motorcycle is started. Development of motorcycle recorders: The predecessor of motorcycle recorders - dash cams. The development of dash cams has solved many employment issues while also providing users with safety assurances. As society continues to progress, the development of the industry is the result of the hard work and innovation of numerous engineers.

What Happens If You Accidentally Shift to P While Driving?

If you accidentally shift to P (Park) while the car is moving, although the P gear can be used to achieve a braking effect when the car's brakes fail, suddenly shifting into P during normal driving will produce a series of very loud noises, which come from inside the transmission. Of course, this doesn't cause significant damage to the engine, and the car can still start and drive normally, but it will accelerate the wear of the internal gears in the transmission. Definition of P Gear: In fact, the P gear is equivalent to the function of N (Neutral) plus the handbrake. It can replace the vehicle's braking system when the handbrake fails, preventing the car from rolling. Avoid Using P Gear in Non-Emergency Situations: Of course, you should not use the P gear for braking in non-emergency situations at high speeds, as it can cause significant impact on the transmission. An accident might deform the parking pawl and gear due to high-speed collision, and the pawl could even break. The broken pieces moving inside the transmission can cause irreversible damage or even render it completely unusable.

Can New Energy Gasoline Be Used?

Hybrid new energy vehicles can use gasoline, while pure electric vehicles cannot. The working principle and output characteristics of new energy vehicles are as follows: Working Principle of New Energy Vehicles: Electric vehicles are mostly automatic transmission. Structurally, pure electric vehicles use the three-electric system as the power source, and they do not have a transmission. According to the working principle of pure electric vehicles, they operate by supplying electrical energy from the battery to the motor, driving the motor to run, thereby propelling the vehicle. Output Characteristics of New Energy Vehicles: New energy vehicles generally do not come with multi-stage transmissions because the torque output characteristics of the motor eliminate the need for a "transmission" to coordinate the relationship between speed and torque.

Can New Energy Vehicles Drive Through Water Accumulation During Rain?

New energy vehicles can drive through water accumulation during rain. The batteries of electric vehicles are completely sealed structures, and there is no danger if they are submerged in water. In addition, the electrolyte in the battery requires very high purity, and external water is strictly prohibited from entering. New Energy Vehicles: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. Classification of New Energy Vehicles: New energy vehicles include: hybrid electric vehicles (HEV), battery electric vehicles (BEV), fuel cell electric vehicles (FCEV), hydrogen engine vehicles, as well as gas-powered vehicles, alcohol ether vehicles, etc.
