The illumination of the engine warning light on the Jialing Coco may indicate poor engine performance. Possible reasons for the engine warning light to illuminate: Poor gasoline quality leading to incomplete combustion in the cylinder, resulting in carbon deposits; Carbon buildup in the intake tract and piston top causing poor atomization and incomplete combustion; Excessive mileage leading to weakened spark plug performance; Faulty ignition coils causing poor ignition and incomplete combustion; Advanced vehicle age with mechanical aging resulting in poor engine performance and ignition issues. Engine: The engine is the device that provides power to the vehicle, determining its power, fuel efficiency, stability, and environmental performance. Engine types include diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.

Speaking of the engine warning light issue on the Jialing COCO, I encountered a similar problem last time when riding my friend's COCO. Generally, there are three main reasons: sensor malfunctions like carbon buildup on the oxygen sensor or a faulty coolant temperature sensor; fuel system issues such as clogged injectors due to poor-quality gasoline; or potential ignition system problems. I recommend first checking if the fuel tank cap is tightened properly—sometimes it's that simple. If the light stays on after restarting the engine, don't force the ride; head to a repair shop immediately to read the fault codes. The electrical systems on these small-displacement bikes are quite sensitive, especially the fuel-injected versions—avoid tampering with the fuse box casually. Regular use of fuel system cleaners during maintenance can help prevent such issues.

What is the passing score for the driving test subject one?

The passing score for the driving license test subject one is 90 points, with a total of 100 questions. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the test consists of single-choice questions and true/false questions, each worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the test, the system will automatically submit the test and end the exam. Subject one, also known as the theoretical test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer with a time limit of 45 minutes. Subject one test content: driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject one test precautions: Candidates should pay attention to their attire during the test; no slippers are allowed, and electronic devices and bags are not permitted in the examination hall. Bring your ID card and queue up to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in the locker before entering the examination hall. Upon entering the examination hall, the identity verification area will assign a seat. After finding your seat, begin the test. Ensure the camera is aligned with you and follow the exam discipline. If you fail the first time, there is a retake opportunity on the same day. If you fail again, you will need to pay and reschedule. After the test, queue up to collect the score report and sign it. Failure to sign will render the test invalid. Subject one appointment: Candidates can make online appointments through mobile apps (iOS 15 or above, Traffic Management 12123 (V2.8.1B437) or Android 12 or above, Traffic Management 12123 (V2.8.1B274)). On the app's homepage, select "58 Car Test Appointment" and fill in the information as prompted. There is no limit to the number of times you can schedule the subject one test. Each subject can be taken once, and if you fail, you can retake it once. If you do not attend the retake or fail the retake, the test will be terminated, and the applicant must reschedule. For subject two and subject three, there are only five test opportunities, and subject two and subject three tests should be scheduled ten days later. If you fail the subject three safe and civilized driving knowledge test, the passed road driving skills test scores remain valid. The driving test consists of three subjects: subject one, subject two, and subject three. Subject one refers to the road traffic safety laws, regulations, and related knowledge test; subject two refers to the field driving skills test; subject three is divided into two parts: road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after subject three, so it is commonly referred to as subject four. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as subject four.

Can an Air Filter Be Reused?

It can be reused, but replacement is recommended. Using compressed air to blow it out or washing it with water can remove thick accumulated dust, but dust trapped inside the paper is difficult to clean thoroughly. The function of an air filter: to filter out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinder and preventing floating dust from being sucked into the engine, which accelerates the wear of the piston group and cylinder. According to the car's maintenance manual, the air filter should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The position of the car's air filter is determined by the intake form and the engine's structure. It is usually located in the air cleaner on the engine's intake pipe. 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. Air filter: It is a type of filter, also known as an air 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 cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. The air cleaner 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 overly dirty air filter while driving can cause insufficient engine intake, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car's air filter must be kept clean. The car's air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinder, reducing early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must first pass through the fine filtration of the air cleaner. An overly dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if it is found to have little dust and minor clogging, it can be cleaned by blowing it out with high-pressure air from the inside out and continue to be used. An overly dirty air cleaner should be replaced promptly.

Why do the car lights stay on after the engine is turned off?

The ACC control wire was probably not connected during installation. The aftermarket LED daytime running lights are not part of the original vehicle system and cannot be controlled by the onboard computer. If the ACC control wire is connected, the daytime running lights will turn on when the vehicle's ACC is working and turn off when the engine is shut down. Without the ACC control wire connection, the daytime running lights are controlled by the power supply voltage. Additional information: Enhancing headlight brightness improves driving safety. As spring arrives, increasingly frequent rainfall exacerbates the situation for drivers who already find their headlights insufficiently bright. Rain reduces the penetration of light, and the high reflectivity of wet roads creates significant visibility challenges for nighttime driving.
