How many points will be deducted for car overload?

Overloading a car by one person will result in a deduction of 2 points. If it is a passenger vehicle overloaded by one person, 6 points will be deducted. Hazards of overloading: Overloaded cars have increased inertia and longer braking distances. The extension of non-safe zone distances can easily lead to traffic accidents; overloading will shorten the service life of leaf springs. Due to overloading, the leaf springs are subjected to excessive force and continuously rebound during driving, which will shorten the life of the springs. Moreover, due to excessive load, the vehicle sinks overall, reducing the distance from the ground and diminishing the vehicle's passage capacity. Violation handling: Generally, after a violation, an SMS reminder will be sent within 1-3 working days. Generally, as long as it is handled before the annual inspection, there will be no problem. At the same time, it should be noted that on-site violations will incur late fees if they exceed 15 days. To pay the fine, the driver only needs to bring the vehicle's driving license and their own driver's license.

Do I still need to shift to N gear with autohold?

When autohold is engaged, it is equivalent to pulling the handbrake while in D gear. As for whether to shift back to N gear, it depends on the vibration of the car. The function of autohold: Autohold is equivalent to an automatic handbrake. When the brake is pressed, the electronic handbrake will automatically engage. It works particularly well with auto start-stop because when the brake is fully pressed, both autohold and auto start-stop come into effect, and the engine is in a shutdown state, so there's no need to consider gear issues at all. If the car does not have an auto start-stop function, autohold being engaged is equivalent to pulling the handbrake while in D gear. As for whether to shift back to N gear, it depends on the vibration of the car, as the driving force is still competing with the handbrake. For cars with significant vibration, it may be better to shift back to N gear. When to shift back to N gear: For situations like waiting at a red light, there is no need to change gears at all. However, when parked on the roadside for a long time, remember not to keep the car in D gear.

Why was I deducted 100 points for rough gear shifting?

Subject 3 failed due to rough gear shifting because the clutch was not fully depressed during gear changes. Reasons for rough gear shifting: The clutch was not fully depressed during gear changes. Additionally, gear shifting must be done sequentially and match the vehicle speed. During gear changes, the clutch must be fully depressed, and neither the accelerator nor the brake should be pressed. Subject 3 primarily tests the coordination between the accelerator and clutch during gear changes. Gear shifting techniques: Ensure sufficient throttle is applied, and after each gear shift, proceed decisively to the next shift. Gear shifting actions, including hand and foot movements, should be fast, precise, and coordinated. Keep the left foot on the clutch and the right hand on the gear lever. After starting, accelerate and shift up to 5th gear by the 50-meter mark, then begin braking and downshift to 2nd gear, leaving some distance margin. Throughout the process, use the left hand to maintain proper steering control to avoid deviation.

Causes and Solutions for Odors in Car Air Conditioning Systems

Here are the reasons why air conditioning systems may produce odors: 1. Prolonged use of the air conditioner can lead to the accumulation of dust on the indoor filter and inside the copper coils. When a certain amount of dust builds up, it can generate an odor, which is then dispersed into the air when the air conditioner is turned on. 2. After cooling or heating, the indoor unit of the air conditioner often retains moisture. If the air conditioner is turned off immediately without a drying or anti-mold function, the moisture remains inside, leading to the growth of mold over time, which produces a musty smell. Here are some methods to eliminate odors: 1. If the air conditioner has been used for a short period and only has dust on the panel and vents, simply wipe it down and remove the filter for rinsing with clean water. 2. If the air conditioner has been used for a long time and the user cannot perform a simple cleaning, it is necessary to contact after-sales service for a thorough cleaning to ensure the air conditioner emits healthier and fresher air.

What does it mean to replace spark plugs one by one?

Replacing spark plugs is actually part of routine maintenance, just like changing engine oil and the three filters. A set of spark plugs usually consists of four, and it is generally recommended to replace all four together rather than one by one. Reasons for replacing spark plugs: Regular maintenance parts for cars have a specific cycle. The replacement cycle for spark plugs typically ranges from 20,000 to 100,000 kilometers (depending on the material). However, this doesn't mean they become unusable immediately after reaching the manufacturer's specified limit. Most products are designed with a safety margin, so exceeding the cycle won't immediately cause fatal damage to the engine. However, after surpassing the recommended mileage, electrode wear accelerates, the electrode gap widens, and unstable ignition requires higher voltage. Mild symptoms include sluggish acceleration, misfires, and increased fuel consumption. In severe cases, electrode breakage may occur, potentially damaging the engine. Methods for replacing spark plugs: Mechanics usually replace all spark plugs at once. Theoretically, even if you replace one with the same brand and model, the discharge gap and resistance between new and old spark plugs differ. Not replacing all of them can lead to issues like engine shaking, difficulty in acceleration, and increased fuel consumption. This means that differences in spark plugs can cause variations in ignition timing and energy, resulting in an imbalance in power among the four cylinders.

Which car models are equipped with variable cylinder engines?

2021 Buick LaCrosse, Buick GL8, and Cadillac XT4 are all equipped with 2.0T variable cylinder engines. Below is a relevant introduction about the 2021 Buick LaCrosse: Exterior: The new wing-style grille is inspired by the Buick Avista concept car. The larger-sized grille extends horizontally to the wing-shaped LED headlights and integrates with them, significantly enhancing the visual width of the 2021 Buick LaCrosse. The rich and three-dimensional design, complemented by just the right amount of chrome trim, exudes luxury and sophistication. Performance: The 2021 Buick LaCrosse is powered by a 2.0T variable cylinder turbocharged engine. Based on the modular design concept of optimizing single-cylinder performance and utilizing a series of innovative technologies including variable cylinder technology, it achieves a better balance between fuel consumption and power, with a combined fuel consumption of only 6.9L. The engine's maximum torque of 350N-m is achieved at just 1500 rpm, providing more abundant low-end torque and significantly improved power response.
