Why is the car weak and slow after replacing the controller?

The following are the reasons why the car is weak and slow after replacing the controller: 1. Battery aging: A new battery has sufficient power, providing strong performance and fast speed. However, after a year of use, the battery's capacity to hold charge decreases, and it quickly depletes even after a full charge. 2. Battery quality: When buying an electric vehicle, it is essential to choose a high-quality battery and not just go for the cheapest option. Cheap products often lack quality, and some may look good on the outside but have poor internal components. 3. Temperature effects: The performance of an electric vehicle's battery varies between summer and winter. The battery works better in summer, allowing for longer distances, while in winter, due to temperature effects, the battery's charge-holding capacity decreases, reducing the distance the vehicle can travel.

Where to Apply Oil When the Clutch Pedal Squeaks When Pressed?

You can apply oil to the joint of the clutch connecting rod. Here are the relevant details: 1. Causes: The clutch pressure plate spring may be broken or the release bearing may be loose; the clutch steel plate may be shattered; the clutch release lever may be broken, excessively worn, or the release lever adjustment bolt may be broken. Most often, it is due to quality issues with the clutch release bearing. 2. Clutch Location: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine with the transmission, thereby cutting off or transmitting the engine's power to the transmission.

What is ecowing tire?

ecowing is a Kumho tire. Here are some related introductions about tires: 1. Wear: Tires have wear indicators. There are triangle marks on the sidewall of the tire. When the tread wears down to the level indicated by the triangle mark, it is recommended to replace the tire. There are also raised markers inside the tread grooves. When the tread wears down to the level of these raised markers, the tire should be replaced. Simple punctures can be repaired without needing replacement, but bulges must be replaced. 2. Aging: Rubber oxidizes in the air, and oxidized rubber hardens, reducing grip. Therefore, even if a set of tires is not used, their lifespan will still decrease. It is not recommended to use tires for more than 5 years from the date of production. The production date can be found on the sidewall of the tire.

What kind of lubricating oil should be added to a centrifugal pump?

Centrifugal pump bearings are lubricated with LHV-46 lubricating oil or L-HV-32 lubricating oil. Below is the relevant introduction: 1. Principle: Centrifugal pumps work by using the rotation of the impeller to generate centrifugal motion in the water. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started to drive the pump shaft, impeller, and water in high-speed rotational motion, causing the water to undergo centrifugal motion and be thrown to the outer edge of the impeller, flowing into the pump's pressure pipeline through the volute-shaped pump casing. 2. Main function: The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

What are the operating techniques for manual transmission?

Here are the specific operating techniques for manual transmission vehicles: 1. When starting the vehicle: After idling for about half a minute, press the clutch, shift into 1st gear, simultaneously press the foot brake with your right foot, release the handbrake with your right hand, and slowly lift the clutch. 2. While driving: When the speed reaches 15 to 20 km/h, shift into 2nd gear; when the speed reaches 25 to 30 km/h, shift into 3rd gear. 3. Decelerating and stopping: Press the brake to reduce the speed to a safe level, press the clutch, and shift into neutral. 4. Gear shifting: Depress the clutch fully in one motion, and shift gears decisively. Familiarize yourself with the gear positions. If you encounter difficulty shifting, shift into neutral, release the clutch briefly, then depress the clutch again to shift successfully.
