What is the Wuling PCV valve?

PCV valve, also known as the crankcase forced ventilation valve, is a component of the crankcase forced ventilation system in a car engine, primarily serving to enhance air circulation within the engine. The PCV valve consists of a valve body, valve, valve cover, and spring, and is non-disassemblable. Its working principle involves directing gases from the crankcase into the intake manifold through the PCV valve, allowing a small amount of air to enter the intake manifold directly from the air filter via the PCV valve. The PCV valve helps prevent issues such as icing at the throttle, incomplete combustion, and worsened emissions. To check if the PCV valve is functioning properly, after the engine stops running, remove the PCV valve and shake it by hand. If a 'click' sound is heard, the PCV valve is flexible and usable. Otherwise, it indicates that the PVC valve is damaged or malfunctioning, and it should be inspected and repaired at a 4S shop as soon as possible. A damaged PCV valve can directly lead to incomplete engine combustion, resulting in reduced power performance. Not only does this make the car consume more fuel during driving, but it also increases carbon deposits inside the engine due to reduced ventilation performance, affecting the normal operation of other components. Therefore, it is recommended to repair it promptly.

How often should the cabin air filter and engine air filter be replaced?

The replacement interval specified in the vehicle maintenance manual indicates that the engine air filter should generally be replaced every 20,000 to 60,000 kilometers. If the driving mileage is relatively low, it is recommended to replace it every 12 months. The cabin air filter should be replaced approximately every 10,000 kilometers. If it is not replaced for a long time, it will affect the performance of the air conditioning system and the health of the vehicle occupants. Cabin Air Filter: The cabin air filter is a crucial component in the vehicle's air conditioning system. Its primary function is to filter out bacteria, PM2.5 particles, moisture, pollen, dust, and other contaminants from the air. It is recommended to inspect both the engine air filter and cabin air filter during every maintenance service. The engine air filter's location varies depending on the intake design and engine structure, but it is typically housed in the air cleaner attached to the engine's intake pipe. The cabin air filter is usually installed beneath or inside the glove compartment on the passenger side, though some models place it below the windshield in front of the passenger seat. Function of Cabin Air Filter: It absorbs fine particles, reduces respiratory discomfort, minimizes irritation for allergy sufferers, and protects the air conditioning cooling system. Without the cabin air filter, these particles would enter the cabin, contaminating the air conditioning system, reducing cooling efficiency, and potentially causing allergic reactions, lung damage, or irritation from ozone exposure, all of which could compromise driving safety. Dirty Cabin Air Filter: A clogged cabin air filter can restrict airflow, impair cooling performance, increase fuel consumption, and generate noise, ultimately shortening the air conditioning system's lifespan. Accumulated contaminants on the filter can breed bacteria and mold, posing health risks to passengers and potentially leading to illnesses. Engine Air Filter: Also known as an air filter cartridge or air cleaner, this component is essential in vehicles, agricultural machinery, laboratories, sterile environments, and precision operation rooms. Function of Engine Air Filter: It filters airborne particles, ensuring the engine cylinders receive sufficient clean air while preventing dust from entering the engine, which could accelerate wear on piston assemblies and cylinders. Dirty Engine Air Filter: Using an excessively dirty engine air filter can restrict airflow, causing incomplete fuel combustion, unstable engine operation, reduced power, and increased fuel consumption. Therefore, maintaining a clean engine air filter or replacing it promptly is crucial.

What are the symptoms of a damaged catalytic converter?

The symptoms of a damaged catalytic converter are: 1. Unpleasant exhaust odor; 2. Engine overheating and premature excessive wear; 3. Lack of engine power with abnormal noises. The causes of catalytic converter damage are: 1. Blockage due to sintering of ethanol gasoline gum deposits, sulfur-phosphorus chemical complexes, lead-manganese metal deposits, or melting/blockage of ceramic substrates caused by engine exhaust flames; 2. Loss of surface precious metal activity, rendering it incapable of catalytic function; 3. Prolonged exposure to high temperatures leading to thermal deactivation. The catalytic converter is an external purification device installed in the vehicle's exhaust system, which converts harmful carbon monoxide, hydrocarbons, and nitrogen oxides from vehicle emissions into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions.

Why Does an Automatic Car Shake When Shifting to Reverse Gear?

The reasons why an automatic car shakes when shifting to reverse gear are: 1. Low idle speed; 2. Throttle or fuel injector clogging leading to poor air intake; 3. Severe engine carbon buildup; 4. Poor spark plug performance. The solutions for an automatic car shaking when shifting to reverse gear are: 1. Clean the throttle, fuel injector, and fuel passages; 2. Check the wiring or replace the spark plugs. The steps for reversing an automatic car are: 1. Press the brake and shift to R gear; 2. Gently release the brake to enter the parking space. The method for controlling the steering wheel while reversing is: 1. When reversing, if the rear of the car needs to go left, turn the steering wheel to the left; if the rear needs to go right, turn the steering wheel to the right; 2. To straighten the car body, if the rear is leaning left, turn the steering wheel to the right; if the rear is leaning right, turn the steering wheel to the left; 3. After correcting the car body, straighten the steering wheel and reverse slowly.
