Misfiring generally does not cause engine cylinder scoring. Cylinder scoring in an engine occurs due to insufficient engine oil or excessively high engine temperatures. Below is some information about automotive engine oil: The engine cannot operate without engine oil, as it serves functions such as lubrication, cleaning, sealing, heat dissipation, buffering, and rust prevention within the engine. Additional details: 1. During normal engine operation, engine oil forms a protective oil film on the surfaces of various engine components. This reduces friction between parts and prevents direct contact that could generate excessive heat. 2. Without this oil film, high-speed engine operation would cause intense friction between components, instantly generating substantial heat that would be detrimental to the engine.

Which Hongqi model requires political vetting?

All models require political vetting. After all, as the imperial carriage, although it has been civilianized, it still represents the honor of the country and the faith of the nation. Hongqi is a premium brand directly operated by FAW Group, managed by the headquarters of FAW Group. Here is some additional information: Hongqi Cars: In 1958, the Hongqi car was born and became the official vehicle for state leaders and major national events. During the 1960s and 1970s, Hongqi cars became a banner of China's automobile industry. After the reform and opening-up, while continuing to bear the responsibility of being the 'national car,' Hongqi began to move towards marketization and commercialization.

What Causes a Battery to Not Hold Charge?

When a battery fails to hold charge due to severe sulfation or water loss, and its exterior shows no damage, bulging, or signs of short/open circuits, the following repair methods can be attempted: 1. Charging: Perform depolarization charging using positive-negative pulse charging, followed by a complete discharge. Repeat this cycle three times. If capacity shows signs of recovery, additional cycles may enhance the repair effect. 2. Water Refill: Only use deionized or purified water for refilling—never tap water, as it can cause excessive self-discharge. Most modern batteries are maintenance-free, though older models may allow electrolyte top-ups. Avoid prolonged use of audio systems or air conditioning after engine shutdown to prevent deep discharge. Typically, batteries last 2-3 years.

Are the Brakes of Rear-Wheel Drive Cars on the Front or Rear Wheels?

Brakes are present on both the front and rear wheels. For sedans and compact cars, braking primarily relies on the front wheels, with the rear wheels serving as auxiliary support. However, the rear wheels also function as the parking brake. Generally, front wheels are equipped with disc brakes (with one brake caliper per wheel), while most rear wheels use drum brakes (with two brake cylinders per wheel). Drum brakes are less effective than disc brakes. Here is additional information: Rear-Wheel Drive Cars: Acceleration and braking operate in a relatively straightforward manner, as these are linear motions. Essentially, they maximize the friction between the tires and the road. During acceleration, it is noticeable that the front of the car lifts up—more pronounced in some vehicles and subtler in others. This lifting effect is particularly evident when starting with the foot brake applied or the parking brake engaged.

What Causes the Clicking Sound When the Battery Fails to Start the Engine?

The clicking sound when the battery fails to start the engine is caused by insufficient battery power preventing ignition. Here are specific measures to avoid battery depletion: 1. Parking at night: Shift the gear to neutral or N position, and observe if the car lights dim. When the vehicle is in neutral, the engine idles, and the lights are powered entirely by the battery. If the battery is low on charge, the lights will dim. 2. Replacing the battery: It is recommended that owners replace the battery with a high-quality one to avoid purchasing inferior products. Regular cleaning of dust and oxides on the battery surface is necessary during use. 3. Developing good car usage habits: Turn off headlights, air conditioning, and other electrical devices before parking. Wait a few minutes after starting the vehicle before using the air conditioning or other electrical appliances. This reduces the instantaneous load on the car battery and extends its lifespan.

Why can't the Geely Emgrand shift gears?

The following are the specific reasons why the Geely Emgrand cannot shift gears: 1. P-gear locking solenoid valve failure: To prevent the vehicle from accidentally shifting into other gears when starting, there is a P-gear solenoid valve, which needs to receive the signal from the brake pedal to release. These two components are interconnected, and if either one fails, it will prevent the gear lever from being pushed out of P-gear and into other gears. 2. Internal failure of the gear lever assembly: The gears inside the gear lever wear out, causing the gear lever to get stuck and making it difficult to pull back and forth, resulting in the inability to shift gears or difficulty in shifting. 3. Incomplete clutch disengagement: It may be due to failure of the clutch disc and clutch pressure plate, requiring replacement of the clutch three-piece set, including the friction disc, pressure plate, and release bearing.
