Vehicle maintenance warning lights generally need to be cleared at a 4S shop using a computer. There are many types of faults indicated by these warning lights, such as the coolant temperature light, engine fault light, and oil pressure warning light, which require constant attention as they relate to the engine and can affect driving safety. When these warning lights appear, it is advisable to have the vehicle inspected and repaired promptly. Special attention should be paid to the engine fault light. The engine is one of the core components of a car, with a complex structure and numerous sensors. If an issue arises, the engine fault light will illuminate and remain on. For driving safety, it is necessary to visit a 4S shop to use the onboard diagnostic system to determine the specific fault code and carry out timely repairs.

Where is the three-way catalytic converter installed?

The three-way catalytic converter is located at the front end of the engine exhaust pipe, between the front and rear oxygen sensors. Here is more information about the three-way catalytic converter: 1. The function of the three-way catalytic converter is to convert harmful gases such as CO (carbon monoxide), HC (hydrocarbons), and NOx (nitrogen oxides) emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Since this converter can simultaneously transform the three major harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter. 2. After prolonged use, substances like carbon deposits in the exhaust can adhere to the porous ceramic substrate of the three-way catalytic converter, which may lead to clogging over time. If the three-way catalytic converter becomes clogged, cleaning is required to restore its optimal performance.

What is a three-cylinder car?

A three-cylinder car refers to a vehicle equipped with a three-cylinder engine. The fundamental principle of a three-cylinder engine involves converting the chemical energy of gasoline or diesel into thermal energy. This is achieved by igniting the compressed air-fuel mixture within the sealed cylinders, causing expansion that drives the pistons, thereby transforming thermal energy into mechanical energy. Its primary application is to power traditional internal combustion engine vehicles as well as hybrid electric vehicles. A three-cylinder engine consists of three cylinders, three pistons, and three connecting rods. It is characterized by lighter weight and more compact dimensions compared to larger engines. The reduced mass contributes to improved fuel efficiency and lower exhaust emissions, while the smaller size facilitates the integration of hybrid systems. Many hybrid vehicles utilize three-cylinder engines.

What does the OBD interface mean?

The OBD interface in a car is similar to a power socket. Its function is to allow technicians to connect a computer to the OBD interface to access vehicle information and status. For example, if a vehicle generates a fault code, the maintenance personnel can simply connect a computer to the OBD interface to diagnose the issue and proceed with repairs. Another example is during the annual vehicle inspection, where the OBD interface is also required. Below is some relevant information: OBD, short for On-Board Diagnostics in English, means onboard self-diagnostic system in Chinese. As the name suggests, this function can diagnose the vehicle's status. By connecting to the OBD interface, real-time vehicle data can be viewed, and faults can be detected, providing convenience for vehicle repair, development of vehicle-related functions, and modification of vehicle equipment.

Does Car Windshield Washer Fluid Need to Be Diluted with Water?

For household cars, there is no need to dilute the windshield washer fluid with water; simply purchase a bottle from a car wash shop and add it directly. Here is more information about car windshield washer fluid: 1. Car windshield washer fluid is generally categorized into summer-use 0°C fluid and winter-use -20°C or -35°C fluid. 2. Car windshield washer fluid is made from deionized water and various environmentally friendly additives. It has functions such as cleaning, soaking, antifreeze, anti-static, and anti-corrosion, effectively removing dust, lubricating oil, gasoline, diesel, residual polishing wax, chewing gum, bird droppings, and highway insect residue. 3. It can quickly disperse rainwater on the windshield, preventing drivers from having blurred vision during heavy rain.

Why does the auto start-stop function light keep flashing?

The reasons why the auto start-stop function light keeps flashing are: 1. High-power electrical appliances are in use; 2. The water temperature is low. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) and restarts it when it's time to move forward again. Precautions for using the auto start-stop system include: 1. Quickly shift to P gear and release the brake when the engine stops; 2. Reduce current consumption; 3. Do not repeatedly press the brake when the engine is off; 4. Wait for the engine speed to drop to zero before engaging the starter gear and restarting; 5. Do not activate the auto start-stop system during low-speed parking or when the air conditioner is on.

What are the reasons why the car window cannot be closed?

The reasons why the car window cannot be closed are: 1. The window lift switch is faulty; 2. The screws fixing the lift are loose; 3. The window guide rail is blocked or the rubber seal is aged; 4. The installation position of the guide rail is deviated. Solutions for the car window not closing: 1. Replace the lift switch; 2. Tighten the fixing screws of the lift; 3. Clean the guide rail of debris or replace the rubber seal; 4. Install the guide rail in the correct position. Car window maintenance methods: 1. Regularly clean the window glass and guide rails; 2. Regularly check the window switch and fuse; 3. Frequently lubricate the lifting mechanism; 4. Apply rubber protectant to the rubber parts supporting both ends of the glass.
