What to Do When the Car Battery Won't Start the Engine?

Solutions for insufficient battery power preventing engine start are as follows: 1. Jump-start the battery. 2. Seek assistance from an auto repair shop or insurance company. Auto repair shops typically have dedicated batteries for rescue services, but this is charged based on distance. 3. After successfully starting the engine using the above methods to recharge the battery, it is not recommended to immediately replace the battery. Solutions for when the car has power but won't start: 1. Check the car's timing. Inaccurate timing can also cause the car to have power but not start, which is a relatively common reason. 2. Check if the spark plugs need replacement. Typically, spark plugs should be replaced every 40,000 kilometers. 3. It may be related to clogged fuel injectors. If there is excessive carbon buildup or even blockage in the fuel injectors, it can affect gasoline atomization, making it impossible to start the car. 4. Inspect the intake pipe for blockages. If the intake pipe is blocked and air cannot enter, the car won't start because gasoline combustion requires oxygen.

What Causes the Car to Jerk at Low Speeds After Turning on the Air Conditioning?

The reasons for the car jerking at low speeds after turning on the air conditioning are as follows: 1. The engine control logic is faulty and cannot receive the signal indicating the air conditioning is on. When it cannot determine whether the air conditioning is on, the engine control unit (ECU) mistakenly interprets it as a temporary high load and attempts to compensate for the resistance at idle by increasing the engine speed. When the engine speed decreases, it cannot handle the load from the air conditioning compressor, causing the speed to increase again. This back-and-forth results in low-speed jerking. 2. The air conditioning control circuit is faulty and cannot send the signal indicating the air conditioning is on. Similar to the first point, because the ECU cannot determine the air conditioning's status, it continuously adjusts the idle speed, leading to low-speed jerking. 3. A fault in the air conditioning circuit causes the air conditioning to work intermittently. When the air conditioning is off, the compressor belt runs without load, so it does not affect the engine load. However, intermittent operation of the air conditioning compressor forces the engine to continuously adjust the idle speed, resulting in low-speed jerking. Fuel-injected engines are equipped with an engine control unit that manages and adjusts the appropriate idle speed to keep the engine running in a low-power state without stalling.

What are the penalties for driving without compulsory traffic insurance?

Driving without compulsory traffic insurance will result in a warning or a fine ranging from 20 to 200 yuan according to the "Road Traffic Safety Law." Article 95 stipulates: If a motor vehicle driven on the road does not display an inspection qualification mark or insurance mark, or if the driver fails to carry the vehicle registration certificate or driver's license, the traffic management department of the public security organ shall detain the vehicle and notify the party to provide the corresponding license, mark, or complete the required procedures. Compulsory Traffic Insurance for Vehicles: The full name of compulsory traffic insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates for personal injuries, deaths, and property losses (excluding vehicle occupants and the insured) caused by road traffic accidents involving the insured vehicle, within the liability limits. The premium is based on the nationally unified standard rates. However, the price of compulsory traffic insurance varies for different vehicle types, primarily influenced by the number of seats. Compared to the more than 20 exemption clauses in commercial third-party insurance, compulsory traffic insurance covers a much broader range, including losses caused by intentional acts of the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses caused by the accident. Moreover, regardless of whether the insured vehicle is at fault in the accident, compulsory traffic insurance will provide compensation within the liability limits. Introduction to Electronic Insurance Policies An electronic insurance policy refers to a digital policy issued by an insurance company with an electronic signature, using digital signature software and corporate digital certificates that comply with the PKI system. The insurance policy, abbreviated as the policy, is the official written proof of the insurance contract between the insurer and the insured. The policy must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The content recorded in the policy serves as the basis for both parties to fulfill the contract. The policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof marks on paper; Saves time and is convenient, unrestricted by time or location, with information universally accessible online anytime, quickly and easily; Allows for reissuance and resending, eliminating worries about losing it. If a paper version is needed offline, it can also be printed or mailed; Facilitates management, as electronic unification makes it easier for insurance companies and traffic police departments to manage the insurance information of various vehicles.

What does an exclamation mark inside a triangle mean?

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's regular performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: Visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in cars. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark, a red circle with parentheses and an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission fault: A yellow gear with an exclamation mark indicates an automatic transmission fault warning light, signaling a transmission malfunction or transmission fluid below the normal range. Transmission fluid should be replaced promptly. Brake system fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, indicating either a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire pressure anomaly: A bracket with a horizontal line and an exclamation mark in the middle represents a tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is a lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair. Alternatively, you can perform a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

What Causes Engine Shaking and Lack of Power After Driving Through Water?

After driving through standing water, the car shakes and lacks power because a small amount of water enters the high-voltage wires during wading, causing poor ignition and the spark plugs' high voltage to supply the engine block. If possible, it is recommended to use an air compressor to remove and dry the high-voltage wires, or to use the engine's heat to evaporate the moisture. Additionally, it is advisable to dry all electrical wire connections and blow out the air filter. Common causes and solutions for car shaking: 1. Dirty Air Filter: The air filter is designed to protect the engine and reduce wear, typically requiring replacement every 10,000 kilometers. If not replaced in time, insufficient air intake can cause low idle speed, leading to engine shaking. Simply replacing the filter can resolve this issue. 2. Broken High-Voltage Wire: A broken high-voltage wire refers to a break in the wire core, which can affect ignition and cause engine shaking. Use a multimeter to measure resistance and replace the wire with significantly higher resistance. 3. Spark Plug Lifespan: After 30,000-40,000 kilometers, the ignition efficiency noticeably decreases, affecting ignition. This is the most common issue, and replacing all spark plugs can solve it. 4. Low Idle Speed: The engine's idle speed is preset in the computer. When the RPM drops below a certain range, the car's computer automatically adjusts. If the idle speed is too low and causes shaking, it indicates it's beyond the computer's control. Some cars have an adjustment screw on the throttle body to regulate idle speed, while others do not. For the latter, check the idle valve, throttle body, air flow meter, vacuum sensor, and adjust ignition timing (for cars with distributors) to increase idle speed. Low coolant temperature can also cause low idle speed, so check and replace the thermostat if necessary. 5. Abnormal Coolant Temperature: The engine operates within a normal temperature range. High coolant temperature can cause early ignition timing, altered air-fuel mixture, thinning of oil viscosity, and reduced lubrication. Common causes include low coolant level, faulty thermostat, non-functioning fan, or inaccurate temperature switch. Resolving these issues can eliminate the shaking. 6. Clogged Fuel Injectors: Fuel injectors in electronic fuel injection cars are critical components with a long lifespan, often reaching hundreds of thousands of kilometers. However, deposits in gasoline can clog the injector nozzles, causing uneven fuel delivery and inconsistent cylinder operation, leading to engine shaking. The solution is to remove and clean the injectors. 7. Carbon and Oil Deposits: Over time, carbon and oil deposits can clog the throttle body, idle valve, and intake ports, restricting airflow and causing unstable idle speed and shaking. Inspect and clean these areas with a cleaning agent without disassembly to resolve the issue.
