What is the ideal idle speed for a car?

Normally it ranges between 700-800 RPM. Below is relevant information about car idle speed: 1. The function of car idle speed: Idle speed is an operational state of a car, referring to the engine running in neutral gear. The engine speed during idle is called idle speed. Idle speed can be adjusted by modifying parameters like throttle opening. Idling means the engine is "producing power without doing work". When the engine is running and the accelerator pedal is fully released, the engine enters idle state. 2. Causes of unstable idle speed: Direct causes refer to mechanical components being dirty, worn, or improperly installed, leading to variations in cylinder power output which creates imbalance among cylinders, resulting in unstable idle speed; Indirect causes refer to abnormalities in the engine's electronic control system causing poor combustion mixture, making it difficult to balance cylinder power output and resulting in unstable idle speed.

Is it a problem if a sedan scrapes its undercarriage?

Whether the car's undercarriage is affected depends on various circumstances. Below are relevant details about the undercarriage: Different scenarios of undercarriage scraping: Minor scraping generally causes no issues; however, scraping the exhaust pipe or catalytic converter underneath the undercarriage can lead to exhaust system malfunctions. If the vehicle's suspension is scraped and deformed, it may cause wheel alignment problems, resulting in the car pulling to one side or producing unusual noises. Daily maintenance of the undercarriage: Ensure wheel hub bearings are well-lubricated and properly adjusted; adjust the front wheel toe-in appropriately; monitor changes in the front and rear axles and the frame; check the clutch's working condition; adjust brake clearance correctly; and inspect leaf springs for any damage.

Is It Normal for the Car's Air Conditioning to Get Louder After Changing the Filter?

It is normal for the car's air conditioning to become louder after changing the filter. The function of the car's air conditioning filter: It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. It separates solid impurities such as dust, pollen, and abrasive particles from the air. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air and has strong and long-lasting moisture adsorption capabilities. Maintenance of the car's air conditioning filter: If the filter is dirty, clean it by blowing compressed air from the opposite side. Hold the air gun about 5 cm away from the filter and blow at 500 kPa pressure for approximately 2 minutes. The air conditioning filter easily accumulates dust, so blowing away loose dust with compressed air is sufficient.

What Causes Unpleasant Odors in Car Air Vents?

Unpleasant odors in car air vents may be caused by a dirty car condenser. Overview of Car Condenser: The condenser is a component of the refrigeration system, a type of heat exchanger that converts gas or vapor into liquid, transferring heat from the tubes to the surrounding air quickly. Principle of Car Condenser: Gas passes through a long tube (usually coiled into a solenoid), dissipating heat to the surrounding air. Metals like copper, with strong thermal conductivity, are often used to transport vapor. To enhance the condenser's efficiency, heat-conductive fins are often attached to the tubes to increase the surface area for faster heat dissipation. A fan is used to accelerate air convection, carrying the heat away.
