When to Depress the Clutch When Braking in 5th Gear?

When braking in 5th gear, you need to depress the clutch when the speed drops to a relatively low range of 40-50 mph. How to depress the clutch: The most common practice is to observe whether the speed is within the controllable range, such as around 40 mph, which is generally within the controllable range. The controllable range refers to the period when the braking effect is most noticeable. For example, when driving at 100 or 80 mph, the braking distance is longer, and you might feel like the brakes aren't effective enough. However, once the speed drops to 40 mph, you can fully control the speed with the brakes, which is the controllable range. At this point, you can depress the clutch and the brake without significantly affecting the braking distance. Do not depress the clutch too early when braking: When braking to reduce speed, if the engine speed is above 1,300 rpm, it is in a fuel-cut state. During this process, the engine does not output power but is instead dragged by the drivetrain. Therefore, the engine provides braking force rather than traction. This is why it's often said not to shift to neutral or depress the clutch too early when braking.

What Causes Engine Idle Shaking That Stops When Accelerating?

Reasons for engine idle shaking that stops when accelerating: 1. Changes in fuel injection quantity inevitably cause engine speed to fluctuate; 2. Faulty fuel pump pressure regulator or sensor leading to incorrect fuel injection correction signals; 3. Cracked vacuum booster hose; 4. Carbon buildup or dirt on the throttle body, or incorrect throttle position sensor alignment; 5. Faulty spark plugs; 6. Aging engine components. When starting the vehicle or idling with the engine running, noticeable body vibration typically indicates a dirty throttle body or excessive carbon buildup in fuel injectors. If slight body vibration or drift occurs while driving, this is usually caused by tire-related issues.

What speed can a new car reach on the highway after 1000 kilometers?

After running 1000 kilometers, a new car can maintain a speed of 100-120 km/h on the highway, just make sure the engine speed does not exceed 3000 rpm. Precautions during the break-in period: During the break-in period, avoid putting excessive load on the engine, do not drive for excessively long periods, especially avoid prolonged high-speed driving. Operate each gear smoothly, avoid sudden acceleration, and be gentle when starting or going uphill to prevent overly aggressive driving. Recommended speed and engine rpm for different break-in stages of a new car: For the first 500 kilometers (early break-in stage), maintain a speed of 60-70 km/h with engine speed not exceeding 2200 rpm. From 500 to 1000 kilometers (mid break-in stage), keep speed between 90-100 km/h with engine speed below 2500 rpm. From 1000 to 1500 kilometers (late break-in stage), the speed can be increased up to 120 km/h as long as the engine speed stays below 3000 rpm.

Can a Copy of the Vehicle License Be Used to Handle Traffic Violations?

A copy of the vehicle license cannot be used to handle traffic violations. Currently, when dealing with traffic violations, the vehicle owner needs to bring the original driver's license and vehicle license to any traffic police station or administrative comprehensive processing hall in the area where the violation occurred or where the vehicle is registered. Locations for handling traffic violations: On-site processing at the traffic violation processing center. Upon entering the center, you can proceed to the service windows in the hall. Present the relevant documents to process the traffic violation. The staff's computer can display three photos of the violation scene to confirm the violation. Viewing the violation scene records is limited to the local area. For violations in regions like Nanhai or Shunde, you must visit the local authorities to view the records. The entire process, from confirming the violation information to queuing for payment, takes about 15 minutes, but parking in the surrounding area can be relatively difficult. Postal agency for traffic violations: Call the postal customer service hotline at 11185. The staff will explain that there are two modes for handling traffic violations via postal service. One mode requires the vehicle owner to visit a postal office with their ID card, driver's license, vehicle license, and violation notice or related violation information. The other mode involves registering the vehicle owner's information via the 11185 service hotline, after which postal staff will visit to collect the necessary documents for processing.

Are Gasoline Additives Actually Useful?

Although gasoline additives do have practical effects, their impact is not very significant. Additionally, gasoline from domestic gas stations already contains additive components, which further diminishes the effectiveness of additional gasoline additives. The functions of gasoline additives: The primary role of fuel additives ("fuel enhancers") is to clean carbon deposits, which has always been their main selling point. They also help maintain the engine and fuel system. Some specialized fuel additives can even improve the fuel's anti-knock properties (octane rating). Precautions when using gasoline additives: If you decide to use gasoline additives, follow the sequence of adding the additive before filling up with gasoline. This ensures thorough mixing under the impact of the incoming fuel, achieving optimal performance.

How to Remove the Key from an Automatic Transmission Car?

There are two scenarios where the key of an automatic transmission car cannot be removed: it cannot be pulled out after turning off the engine, or it cannot be turned after insertion. Below are the relevant details: Reasons why the key cannot be removed after turning off the engine: The gear shift lever is not fully returned to the P (Park) position. If the gear shift is not the issue, try turning the steering wheel slightly. It could also be due to obstructions like coins in the gear slot preventing it from returning to position. In this case, the owner should check for any foreign objects blocking the gear slot, remove them, start the car, and shift the gear again to ensure it fully returns to position, after which the key can be removed. Reasons why the key cannot be turned after insertion: This is due to the car's steering wheel auto-lock feature, a security function. It usually activates if the driver accidentally turns the steering wheel left or right after parking and turning off the engine, or if the wheels are not aligned properly when parked. The force applied can cause the steering wheel to turn, triggering the auto-lock mechanism, which engages the steering lock pin with the steering column, making the steering wheel immovable. Even if the key is inserted, it cannot be turned forcefully. If the key cannot be turned after insertion, try gently turning the key with your right hand while simultaneously wiggling the steering wheel left and right with your left hand. The key should then turn.
