What Causes High Engine Idle Speed?

High idle speed is mainly caused by the following reasons: 1. The idle switch fails to close; 2. Malfunction of the idle control valve; 3. Air intake pipe leakage; 4. Incorrect valve timing; 5. Fuel injector dripping or clogging; 6. Exhaust system blockage; 7. EGR valve opening during idle operation. Below are the solutions for high idle speed: 1. Adjust or replace the throttle position sensor; 2. Clean or replace the idle control valve and perform basic idle speed setting with a dedicated decoder; 3. Locate the leakage point and reseal or replace related components; 4. Check timing marks and readjust valve timing according to standards; 5. Clean and inspect each fuel injector's spray volume to ensure no clogging or dripping; 6. Replace the three-way catalytic converter; 7. Remove carbon deposits from the EGR valve or replace the EGR valve.

How Much Refrigerant Should Be Added to a Car's Air Conditioning System?

Introduction to Adding Refrigerant to Car Air Conditioning: The amount of refrigerant to be added to a car's air conditioning system is generally around 2-3 cans, with most models requiring between 450-650 grams. The exact amount may vary depending on the vehicle model and the content of the canned refrigerant. In practice, it is essential to follow the manufacturer's instructions in the user manual or rely on the actual pressure readings from the air conditioning pressure gauge. Phenomena and Hazards of Overfilling Refrigerant in a Car: 1. Excessive refrigerant can cause unstable idling, belt slippage, and noise. 2. The pressure relief valve may automatically open and release excess gas. 3. In high-end vehicles, the high-pressure protection compressor may stop working, which can severely lead to the rupture of high-pressure pipes. 4. If the internal refrigerant is insufficient, the internal pressure will be too low, reducing the amount of heat removed during the compression and release process. The air conditioning system will not achieve the desired cooling effect.

Can a small car be equipped with a parking air conditioner?

Can a small car be equipped with a parking air conditioner? The following is a related introduction to parking air conditioners: 1. Introduction: A parking air conditioner is an in-vehicle air conditioner. It refers to a device that uses the vehicle's DC power supply (12V/24V/36V) to allow the air conditioner to operate continuously when parking, waiting, or resting, regulating and controlling the temperature, humidity, airflow, and other parameters of the in-cabin air environment, fully meeting the comfort and cooling needs of truck drivers. 2. System Composition: Due to the limitations of the vehicle's battery capacity and poor user experience in heating during winter, parking air conditioners are mainly single-cooling type. They generally include a refrigerant medium delivery system, cooling source equipment, terminal devices, and other auxiliary systems. The main components include: condenser, evaporator, electronic control system, compressor, fan, and piping system. The terminal devices utilize the distributed cooling capacity to specifically adjust the air conditions inside the cabin, providing truck drivers with a comfortable resting environment.

Can Parking Lot Scratches Be Covered by Insurance?

Yes, it can be covered by insurance. If the car owner has purchased the additional coverage "Third Party Not Found Special Clause" under the car damage insurance, the insurance company will cover the full cost. If the incident occurs in a free parking lot, the parking lot will only be liable for compensation if there is intentional or gross negligence in vehicle storage damage; general scratches do not require them to take responsibility. After the incident, report the case within 48 hours, obtain an accident confirmation form from the traffic police, and then contact the insurance company for claims. Here is supplementary information about vehicle insurance: Vehicle insurance, also known as motor vehicle insurance or auto insurance, refers to a type of commercial insurance that covers personal injury or property damage caused by natural disasters or accidents involving motor vehicles. Auto insurance is a type of property insurance. In the field of property insurance, auto insurance is a relatively young category, as it emerged and developed alongside the appearance and popularization of automobiles. Additionally, unlike modern motor vehicle insurance, early auto insurance primarily focused on third-party liability as the main coverage and gradually expanded to include risks such as collision damage to the vehicle body.

When Should Spark Plugs Be Replaced?

Spark plugs need to be replaced under the following conditions: severe damage to the spark plug, such as blistering at the top, black streaks, cracks, or electrode melting. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance to assess its condition. A normal spark plug will have a skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a skirt that is reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is covered in oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, with blistering, black streaks, cracks, or electrode melting at the top, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, or that engine oil is seeping into the combustion chamber.

Is it harmful to turn off the engine directly when the car's water temperature is too high?

Turning off the engine directly when the car's water temperature is too high is a wrong behavior. When the car's water temperature is too high, first slow down, then pull over to the side of the road. Do not turn off the engine immediately, because excessively high water temperature will cause the piston, cylinder walls, cylinder, crankshaft, etc., to overheat, thinning the engine oil and losing its lubricating effect. If the engine is turned off immediately at this time, the mechanical parts are in an expanded state, and the gaps between various components are very small, which may cause some soft metals to peel off or even lead to cylinder sticking. Reasons for excessively high water temperature: 1. Insufficient coolant: First, check the coolant level. If you are on a highway or in a remote area and there is no coolant in the car, you can temporarily use water as a substitute. Note: Do not open the radiator cap or water tank cap immediately after stopping the car, as the internal pressure is too high, and opening it may cause instant spraying, which can easily lead to burns. 2. Dirty radiator: The radiator has many pores formed by cooling fins, which are prone to being clogged with fluff, sludge, etc., reducing ventilation and cooling efficiency. In winter, poor cooling efficiency is not a big problem because the ambient temperature is low. However, in summer, when the ambient temperature is already high, a clogged radiator with poor cooling can easily cause the water temperature to rise.
