What is the fuel tank capacity of the Changan Oshan X7 in liters?

The fuel tank capacity of the Changan Oshan X7 is 55 liters, as officially announced. Owners who have purchased the Changan Oshan X7 can also check this information on the vehicle's configuration sheet. The Changan Oshan X7 requires 92-octane gasoline, with a fuel consumption of 7 to 7.4L per 100 kilometers. A full tank can cover a distance of 743 to 786 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

Should I Add Antifreeze or Water to the Car Radiator?

You should add antifreeze to the car radiator. Water in daily life is impure and contains impurities. If water circulates in the engine, especially during the major cycle when it flows into the cooling tank behind the intake grille, the impure water can form scale and clog the cooling system. This can lead to reduced engine power, increased wear, and overheating. Additionally, water evaporates easily at high temperatures, causing a shortage in the cooling system, which may result in cylinder scoring, cylinder head deformation, or even engine failure in severe cases. Below is more information about antifreeze: 1. Antifreeze is a coolant with special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent properties such as freeze protection in winter, boil-over prevention in summer, and year-round anti-scale and anti-corrosion benefits. 2. Engines and their cooling systems are made of metals like copper, iron, aluminum, steel, and solder. These metals can corrode and rust over time when exposed to water under high temperatures. In contrast, antifreeze not only prevents corrosion in the engine cooling system but also has anti-corrosion and rust-removal functions. 3. Over 95% of antifreeze used domestically and internationally is ethylene glycol-based. Compared to tap water, ethylene glycol's most notable feature is its freeze resistance, whereas water cannot prevent freezing. Additionally, ethylene glycol has a high boiling point, low volatility, moderate viscosity with minimal temperature variation, and excellent thermal stability. Thus, ethylene glycol-based antifreeze is an ideal coolant.

How Does an Air Filter Work?

Here is how an air filter works: 1. Dry inertial air filter: The dry inertial air filter consists of a dust cover, guide vanes, dust discharge port, dust collection cup, etc. Its working principle is to use the suction force generated by the cylinder during intake to create a pressure difference inside and outside the air filter. External air enters the air filter at a high speed under pressure, throwing larger dust particles mixed in the air into the dust collection cup, thus completing the air filtration. 2. Wet inertial air filter: Also known as an oil bath filter, the wet inertial air filter mainly consists of a central tube and an oil pool. Its working principle is that air enters the filter and moves downward at high speed along the central tube, hitting the oil surface of the oil pool before abruptly changing direction to move upward, creating a rotational motion. At this point, some larger dust particles cannot reverse direction with the air due to inertia and are instead trapped in the oil, completing the air filtration. 3. Dry filtration air filter: The dry filtration air filter mainly consists of a paper filter element and sealing gaskets. Its working principle is that air passes through the paper filter element upon entering the filter, where dust in the air is either blocked by the filter element or adheres to it. 4. Wet filtration air filter: The wet filtration filter mainly consists of metal mesh soaked in engine oil. Its working principle is that after passing through the oil bath filter, air is further filtered through the oil-soaked metal mesh, where fine dust particles are trapped, and some adhered dust particles drip down with the oil.

What does a triangle with an exclamation mark indicate as a warning light?

A triangle with an exclamation mark inside indicates a general performance or component malfunction in the vehicle. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common warning symbol in vehicles. Apart from the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark inside, 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 malfunction: A yellow gear with an exclamation mark inside indicates an automatic transmission fault warning light, signaling a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake system malfunction: 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 vehicle's tire pressure and restore it to the normal range. Lighting malfunction: A yellow bulb with an exclamation mark indicates a lighting fault warning light, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible, or conduct a self-inspection focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

What does it mean when the engine fault light is yellow?

When the yellow engine fault light is on, it is a warning indicating that certain system parameters of the vehicle may have exceeded the set range. At this time, the vehicle can continue to drive, but some functions may be limited. The engine fault light can also be red. When the red fault light is on, it means the vehicle must stop immediately, the engine must be turned off, and driving is prohibited. The vehicle should be checked for faults. There are seven main reasons why the engine fault light may illuminate: 1. Sensor failure: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or their signals are interrupted, the vehicle's ECU cannot accurately obtain engine data, causing the engine fault light to illuminate. 2. Fuel or oil quality issues: If fuel or engine oil is not added as required by the manufacturer, it may cause engine wear and trigger the fault light. 3. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pump failure, or clogged fuel lines can cause poor combustion. 4. Turbocharging problems: Issues with the intake boost piping or turbocharger can also trigger the engine fault light. The most common issue is a damaged turbocharger, which may also cause symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. 5. Intake problems: If the vehicle's intake system is compromised, it may lead to clogged engine pipes, and in severe cases, the engine fault light may illuminate. A dirty air filter that hasn't been cleaned regularly can cause intake issues. 6. Exhaust problems: Exhaust faults can also trigger the engine fault light. Common causes include issues with the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings. The catalytic converter is the most frequent culprit. Using leaded gasoline, lead- or silicon-containing lubricant additives, physical damage to the catalytic converter, or fuel system faults can all lead to catalytic converter failure. 7. Anti-theft system failure: If the vehicle's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine control unit, the system may prevent the engine from operating normally, and the engine fault light will illuminate. If the engine fault light is on, follow these steps: 1. First, check whether the engine is running normally. Look for issues such as shaking or black smoke. If these are present, avoid restarting the engine. Note: If the red light is on, do not restart the engine under any circumstances. 2. If the engine can start, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the "ON" position (without pressing the clutch). The vehicle will enter self-diagnosis mode. After 5-10 seconds, check if the fault light turns off. 3. If the fault light remains on, visit a service center as soon as possible. Technicians can use a diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.
