Do You Need to Press the Clutch and Brake When Turning with a Manual Transmission?

Whether you need to press the clutch and brake when turning with a manual transmission depends on the situation. Here are the relevant details: Driving through a turn: The approach to turning varies depending on the circumstances. For wide turns, you may not need to press the clutch or brake—simply control your speed and apply gentle braking to slow down, then accelerate after completing the turn. For sharp turns with a small radius, it's advisable to press the clutch and brake in advance. Key considerations: Failing to reduce speed may lead to loss of control, while not downshifting can result in insufficient power, causing the car to shake or even stall. After downshifting, maintain gear engagement while turning. In congested areas, use first or second gear, press the clutch, and rely on the car's idle speed to turn while keeping the brake ready for sudden situations.

What is the principle of the idle motor?

The working principle of the idle motor is that the vehicle's computer collects engine operating condition data, calculates the optimal parameters, and transmits them to the idle motor. The idle motor then controls the size of the throttle's idle air passage to ensure stable engine operation. Since the idle motor regulates idle air flow, it is prone to getting dirty. Excessive dust entering the idle motor can impair its precise control and may even cause damage. If the idle motor fails, it will affect the car's idle operation, leading to issues such as difficulty starting, unstable idling, idle shaking, stalling at idle, and sluggish acceleration. If the idle motor is damaged, it should be replaced promptly. However, regular cleaning is crucial to prevent the buildup of carbon deposits and dust. As the idle motor is a precision component, cleaning requires positioning the motor's conical head downward and spraying cleaning agent onto the conical head and sleeve area to remove carbon deposits, followed by wiping it clean. This prevents cleaning agent from entering the motor's interior and causing damage.

What Causes the Jerking Sensation When Downshifting a Manual Transmission?

It is mostly caused by improper clutch operation. Additionally, when shifting at lower RPMs, the jerking sensation is less likely to occur. However, when shifting at higher RPMs, if the throttle is not properly coordinated during upshifting, the vehicle is very prone to jerking after engaging the gear and releasing the clutch. Solutions are as follows: 1. Reduce shifting time: On one hand, try to minimize the shifting time, completing the gear change and re-engaging the clutch before the RPM drops. However, this method is incorrect. 2. Throttle blip: On the other hand, if the shifting is not fast enough, learn to blip the throttle. Before releasing the clutch after shifting (while the clutch is fully depressed), give a slight throttle blip—usually less for upshifts and more for downshifts. The exact amount should match the vehicle speed, and with practice, it can be done by feel. The principle is simple: raise the RPM close to the pre-shift level before re-engaging the clutch.

Why is the rear wheel of a scooter wobbling?

For a wobbling rear wheel, check the following aspects separately: whether the tire pressure is insufficient, whether the rear axle nut is loose, whether the tire has bulges or is improperly installed and twisted, whether the rear shock absorber is too soft, whether the rear wheel bearings are damaged, and whether the rear rim is deformed. The related explanations are as follows: 1. Inspection items: If it is a pedal-assist scooter, also check whether the engine mounting bracket bushings are aged and loose. If it is a underbone or straddle-type scooter, check whether the rear swing arm screws are loose or the swing arm bushings have excessive clearance. 2. Hand test: For a scooter's rear wheel, you can feel slight front-to-back movement by gently pulling it with your hand (this is actually not the wheel's looseness), but there should be no side-to-side movement. If the rear wheel appears to wobble side to side, check whether the tire has bulges or is twisted. Aluminum wheels generally do not deform.

Can a Car Still Drive After Being Flooded?

Whether a car can still drive after being flooded depends on the extent of the flooding. If the water has not submerged the wheels, the car can be driven normally. However, if the water level is too high, it may affect the car's electrical circuits, making it unsafe to drive. If the water has reached the hood of the car, it is best to inspect the vehicle for damage and avoid starting it. If the car stalls after being flooded, do not attempt to restart it. Restarting the engine may cause it to stall again, potentially leading to further damage, which could affect insurance claims later on. After a car is flooded, it is crucial to notify the insurance company immediately and describe the situation. The insurance company will then send someone to inspect the vehicle and assess the damage. In cases of extreme weather where the insurance company cannot arrive promptly, the driver should document the damage themselves. It is advisable to take photos from multiple angles using a camera or smartphone to provide evidence for the insurance company's assessment of the damage.

What is the reason why the Nissan Qashqai suddenly fails to start but has power?

The reasons why the Nissan Qashqai suddenly fails to start but has power are as follows: The engine starts by the battery current pushing the spark plug to ignite. There may be two main reasons causing the engine to suddenly fail to start. First, it is very likely due to battery rust or leakage. Second, it could be caused by the engine spark plug getting damp on rainy days. Maintenance methods: Check the battery fluid level every one to two months to ensure it is sufficient. If the fluid level is between the upper and lower two marked lines, it is considered appropriate. Also, check the fluid level difference in each cell. If the fluid level is insufficient, unscrew the cap on the battery and add distilled water to replenish the fluid level. Additionally, inspect the battery terminals and use a wire brush to remove any accumulated dirt. If the terminal clamps are severely dirty, use sandpaper to scrape off the dirt along the inner wall. If the spark plug is damp, remove it and use a lighter to dry it to quickly evaporate the moisture on it.
