Generally, small cars have a fuel tank capacity of 35-45 liters, while medium-sized cars have a capacity of 55-75 liters. A full tank typically allows for a driving range of around 500 kilometers. The size of the fuel tank correlates with the vehicle's displacement and fuel consumption; vehicles with higher fuel consumption tend to have larger tanks, and those with lower consumption have smaller ones. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by car manufacturers is measured from the bottom of the tank to the safe fill level, leaving some space from the safe fill level to the tank opening. This space is designed to accommodate fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with E (Empty) and F (Full). When the needle is near E, it indicates low fuel, while nearing F means the tank is sufficiently full.

As a seasoned commuter driver, I have some insights to share about fuel tanks. The tank capacity varies significantly across different vehicle models. For regular sedans, it typically ranges between 40 to 60 liters - my family car has a 55-liter tank which is generally sufficient. SUVs usually have larger tanks; for instance, the Highlander can hold up to 72 liters, making it particularly convenient for long-distance trips. However, tank capacity shouldn't be the only consideration - engine fuel consumption matters too. Some vehicles may have large tanks but high fuel consumption, resulting in similar driving range as smaller-tank vehicles with better fuel efficiency. Also, modifying fuel tanks requires caution - unauthorized enlargements may violate traffic regulations and affect vehicle balance. My advice for first-time car buyers: consult the salesperson about both tank capacity and fuel consumption to avoid frequent gas station visits.

What Causes the Engine Warning Light to Illuminate in Baojun Vehicles?

Sensor malfunctions, engine misfires, vehicle maintenance issues, fuel quality problems, poor combustion of the air-fuel mixture, engine intake issues, turbocharging problems, exhaust system faults, and anti-theft system malfunctions are the primary reasons for the engine warning light to illuminate. Additionally, during vehicle startup, the car performs a self-check on the engine system. Normally, the engine warning light should turn off after the self-check. If it remains on for an extended period, it is advisable to seek professional assistance at a service station to diagnose and eliminate potential safety hazards. Below is a detailed explanation of each potential fault: Sensor Issues: Sensors include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen levels, etc. When these sensors are damaged, have poor connections, or signal interruptions, the vehicle's ECU cannot accurately obtain engine data, leading to the illumination of the engine warning light. Solution: Address such issues promptly by visiting a service center for professional diagnosis and elimination of safety hazards. Maintenance Issues: Poor engine maintenance is the most common cause of the engine warning light illuminating. Vehicles have specific maintenance schedules. Failure to adhere to these schedules, combined with poor driving habits, can increase the engine's operational burden, eventually triggering the engine warning light to alert the owner of a fault. Solution: Follow the maintenance schedule outlined in the vehicle's manual, either by time or mileage, to ensure comprehensive maintenance and eliminate non-maintenance-related issues. Fuel Quality Issues: This refers to both fuel and engine oil. The fuel used in cars typically has a specific octane rating, while engine oil can be semi-synthetic or fully synthetic. Manufacturers usually recommend the type of fuel and oil to use. Failure to follow these recommendations over time can cause engine wear, leading to the illumination of the warning light. Solution: Use the recommended fuel octane rating and appropriate engine oil grade for the vehicle. Poor Combustion of Air-Fuel Mixture: Faulty spark plugs, fuel pump issues, or clogged fuel lines can lead to poor combustion of the air-fuel mixture in the engine. This results in engine carbon buildup or knocking, which the oxygen sensors detect and report to the ECU, triggering the warning light. Solution: Inspect the engine's ignition coils and spark plugs; check the performance of related sensors, such as oxygen sensors (front and rear), coolant temperature sensor, intake air temperature sensor, throttle position sensor, air flow meter, and intake manifold pressure sensor. Also, inspect the air filter for contamination—if clogged, it can cause an overly rich mixture, requiring cleaning or replacement. Check for fuel injector leaks and the performance of the fuel pressure regulator, as malfunctions can also lead to an overly rich mixture. It is recommended to visit a professional 4S shop to inspect relevant sensors and the engine control unit. Intake Issues: Engine combustion requires proper air intake, where the air filter plays a crucial role. If the air filter is dirty or not cleaned regularly, it can affect the engine's air intake, potentially leading to blockages over time. Severe cases can cause the engine warning light to illuminate. Solution: Regularly clean or replace the vehicle's air filter to ensure the proper functioning of the intake system. Turbocharging Issues: Problems with the intake turbocharging system or the turbocharger itself can also trigger the engine warning light. The most common issue is a damaged turbocharger, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Solution: Visit a 4S shop to inspect and replace the turbocharger if necessary. In most cases, repairs are not cost-effective, and replacement is the better option. Exhaust System Issues: Faults in the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings can cause the engine warning light to illuminate. The most common issue is a malfunctioning catalytic converter, often due to physical damage or fuel system faults. Solution: Use lead- or silicon-based lubricants to maintain and clean the catalytic converter. Anti-Theft System: If the vehicle's electronic anti-theft system malfunctions or the anti-theft controller is incompatible with the engine control unit, the engine may not operate correctly, and the warning light may illuminate. Solution: Seek professional assistance at a repair shop for a systematic diagnosis and repair.
