What are the steps for manual stationary exhaust self-cleaning on the Fengjun 5?

Reasons for Low Idle Speed

Here are the reasons for low idle speed: 1. Carbon buildup in the throttle body: As the vehicle's usage time increases, the intake passage may become blocked, and carbon deposits or oil in the throttle body can cause unstable idle speed or even low idle speed. 2. Carbon buildup on spark plugs: Over time, carbon deposits can also form on the vehicle's spark plugs. When the buildup is severe, weak sparks from individual cylinders can affect the vehicle's performance, leading to low idle speed. 3. Clogged fuel injectors: When the vehicle's fuel injectors are clogged, it can result in insufficient fuel supply pressure and poor fuel atomization, causing unstable idle speed or low idle speed. 4. Sensor malfunction: If the vehicle's related sensors fail, the correct air-fuel ratio cannot be maintained. Common sensor failures include the coolant temperature sensor, oxygen sensor, and throttle position sensor, leading to high fuel consumption and low idle speed.

What are the body dimensions of the Chery QQ?

The length, width, and height dimensions of the Chery QQ are 3564mm/1620mm/1527mm, which are official data. The length of the Chery QQ refers to the distance between two vertical lines perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the car; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The turbocharged engine of the Chery QQ has a maximum power of 51kW and a maximum torque of 93 N·m. This engine reaches its maximum power at 6000 rpm and its maximum torque between 3500 to 4500 rpm. It is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head. This engine is paired with a 5-speed manual transmission. The state has relevant regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that in the national standard, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.

How Often Should the Air Filter in a New Car Be Replaced?

According to the car's maintenance manual, it is generally recommended to replace the air filter every 20,000 to 60,000 kilometers. If the car is driven less frequently, it is advisable to replace it every 12 months. The location of the car's air filter element varies depending on the intake method and the engine's structure. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. The function of the air filter: It filters out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinder. It prevents floating dust in the air from being sucked into the engine, which could accelerate the wear of the piston group and the cylinder. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that a sufficient amount of clean air enters the cylinder. Using an excessively dirty air filter while driving can cause insufficient engine intake, leading to incomplete fuel combustion. This results in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car air filter is a device that removes particulate impurities from the air. It consists of one or several air filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinder, thereby reducing early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must pass through the fine filtration of the air filter. An excessively dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if it is found to have minimal dust and light blockage, it can be cleaned by blowing compressed air from the inside out and reused. Excessively dirty air filters should be replaced promptly.

What Insurance Should Generally Be Purchased for Family Vehicles?

Family vehicles should purchase compulsory traffic insurance, vehicle damage insurance, and third-party liability insurance. Below are the considerations for purchasing auto insurance: 1. Purchase channels: Pay attention to choosing the right purchase channels, opting for insurance companies with legal qualifications and agents who have professional qualification certificates, business licenses, and formal agency contracts with insurance companies. 2. Consider personal needs: Pay attention to selecting insurance products based on actual needs and fully understand the terms and conditions of motor vehicle insurance. 3. Pay attention to the use of important documents: Be mindful of the use and safekeeping of important insurance documents, fulfill the obligation of truthful disclosure, pay insurance premiums on time, and agree with the insurance company on dispute resolution methods for the contract.

What Causes Severe Shaking When Starting a Manual Transmission Car?

Severe shaking when starting a manual transmission car is usually caused by wear and slippage of the clutch pressure plate and disc, often due to aging or quality issues. This requires simultaneous replacement of both the pressure plate and disc. For novice drivers, driving school vehicles typically have higher idle speeds, allowing smooth starts without throttle input. However, almost all manual transmission cars on the market require gradual throttle application during starts. Details are as follows: 1. Troubleshooting: Car start-up shaking is a very common phenomenon with multiple potential causes, either due to vehicle malfunctions or poor driving habits. Identifying the root cause is essential for timely repairs. 2. Causes of Shaking: When experiencing start-up shaking, carefully investigate the specific reason as different shaking patterns indicate different issues. Recommended procedure: let the engine idle, engage low gear, slowly release the clutch pedal while gradually applying throttle. If significant body vibration occurs, this indicates clutch shuddering. Other possible causes include broken or loose driven plate rivets, fractured driven plate steel sheets, or unbalanced rotating components. Additionally, loose engine mounts or misalignment between the transmission's primary shaft and the engine crankshaft centerline can also cause start-up shaking.

How Long Does a Smart Key Battery Last?

Vehicle smart key batteries typically last 2 to 3 years, depending on actual usage frequency. Below is relevant information about vehicle smart keys: 1. Introduction: Smart keys can emit infrared signals to open one or two doors, the trunk, and fuel filler cap, as well as operate car windows and sunroofs. More advanced smart keys resemble credit cards - when the driver touches the door handle, the central locking system activates and emits a wireless query signal. After the smart key card responds correctly, the door locks automatically open. The engine will only start when the central processor detects the key card inside the vehicle. 2. Functions: (1) Vehicle location. (2) Window control. (3) Lock control and trunk opening. (4) Remote vehicle on/off control within a certain distance.
