What does 'ch' mean on the dashboard?

The 'ch' on the dashboard refers to the water temperature gauge. The water temperature is indicated from C to H. 'C' represents 60 degrees Celsius, and when the needle points to 'C', it means the water temperature has reached 60 degrees. The red 'H' mark indicates a temperature of 110 degrees Celsius, and the span from 60 to 110 degrees allows estimation of the water temperature. Below are reasons for excessively high water temperature: 1. Insufficient coolant: Coolant leakage or low coolant levels can cause the engine water temperature to rise. Regularly check the coolant level and top it up to the appropriate level if necessary. 2. Thermostat failure: The thermostat automatically adjusts the amount of coolant entering the radiator based on the coolant temperature, changing the coolant circulation range to regulate the cooling system's capacity and ensure the engine operates within the proper temperature range. If the thermostat fails, the car's cooling system may not engage in a major circulation, leading to increased water temperature.

Hey, I see the ‘CH’ light on the dashboard is illuminated, which usually indicates the check engine light is activated, meaning there's an issue with the engine that needs attention. The reasons can vary widely, such as an oxygen sensor malfunction, fuel system mismatch, excessive emissions, or even something as simple as a loose gas cap triggering it. Don’t panic—first try turning the car off and restarting it; sometimes it’s a false alarm and the light goes off. But if the light stays on, you’ll need to visit a repair shop to read the trouble codes with an OBD scanner. I’ve seen plenty of cases where people delay addressing this issue, only to end up with reduced engine performance and higher fuel consumption. It’s a good idea to regularly check the air filter and spark plugs to minimize such alerts. For safety’s sake, prioritize fixing it as soon as the light comes on—don’t wait for a small problem to become a big one. From my experience, ignoring it for a month can double the repair costs and also affect your peace of mind while driving.

Ah, as a car owner, I've encountered this before. My heart skipped a beat when the 'CH' light flashed on the dashboard. This should refer to the check engine symbol, indicating an abnormality in certain components of the car. For example, a blocked catalytic converter or insufficient fuel pump pressure can trigger this light. Just last month, my car had this issue, and the mechanic found it was just a minor oxygen sensor problem. The solution was simple: first, make sure the fuel tank cap is tightened to see if the light goes off. If that doesn't work, don't rush to tinker with it—just drive straight to the repair shop. They connected a diagnostic computer and pinpointed the cause in minutes. Ignoring it for too long can lead to increased carbon buildup and higher fuel consumption. Because of this, I've learned to check tire pressure and fluid levels weekly. Before long trips, I always take an extra glance at the dashboard—prevention is better than cure, saving both worry and effort.

How Long Can a Flood-Damaged Car Be Driven?

A flood-damaged car that has been repaired can generally be driven for three to four years, with some lasting four years and others up to five years. Therefore, the actual duration depends on the vehicle's condition. Additional Information: Reasons why flood-damaged cars cannot be fully repaired: Flood-damaged vehicles cannot be 100% restored to their original state and pose significant safety hazards. For example, the electronic systems are prone to short circuits, and if critical systems like ABS anti-lock braking, ESP stability control, or the engine ECU fail to function, the consequences could be disastrous. Other hazards of flood-damaged cars: Additionally, flood-damaged vehicles have other safety risks. Hot components such as the engine and exhaust pipe cool down rapidly when submerged, leading to deformation and increased unbalanced stress, which affects the lifespan of these parts. Moreover, dirty water can corrode the damaged structure of the car body, and some hidden areas cannot be treated with anti-rust paint. Over time, this corrosion weakens the car's structure, which is one of the major reasons why flood-damaged cars should be avoided.

Can a Flooded Car Still Be Driven?

No. Because water has entered the cabin, submerging the chassis, floor, and even the engine. The damp interior is prone to mold and odors, while wiring harnesses and electronic control units are susceptible to corrosion, leading to potential malfunctions later on. Below are the related details: Hidden Dangers of Flooded Cars: 'Flooded cars' can be repaired to some extent, but even after repairs, serious hazards remain. The longer the immersion time, the higher the likelihood of malfunctions. This is similar to a watch falling into water—even if disassembled and dried, the watch will still malfunction and cannot be completely repaired. Hazards: Materials inside the vehicle, such as carpets and seats, may deform, become rough, and develop odors due to prolonged immersion, fostering bacterial growth. Moisture accumulates heavily on the wiring harnesses beneath the carpets, leading to short circuits caused by dampness. These submerged components are best replaced to avoid post-flooding complications. Door panels usually contain soundproofing material, which typically needs replacement. Audio speakers and other components must be replaced after water immersion, or they will fail within days.

What is the National Emission Standard for IV?

National IV refers to the National 4 emission standard. It can fully control compliance through real-time monitoring of vehicle emissions, ensuring better enforcement of the Euro III emission standards. Here is some extended information: 1. National IV Emission Standard: The National IV emission standard is the fourth phase of China's motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). By applying technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard aims to control and reduce vehicle emissions to below specified levels. 2. National 4 Standard: The National 3 and National 4 standards are based on the Euro 3 and Euro 4 vehicle emission standards. Compared to National 2, National 3 further reduces pollutant emission limits. The tailpipe pollutant emission limits under China's National 3 standard are 30% lower than those under National 2, while National 4 will reduce them by an additional 60%. To ensure stable compliance with emission limits during vehicle use and the durability of emission control performance, requirements for On-Board Diagnostics (OBD) and in-use compliance have been added.

Why Doesn't the Fuel Gauge Show Full After Filling the Tank?

Reasons why the fuel gauge doesn't show full after filling the car's tank: 1. Because the fuel pump nozzle automatically stops, it doesn't mean the tank is truly full, so the gauge doesn't display full. 2. The fuel gauge is stuck or reading data incorrectly. 3. There is an issue with the fuel float sensor. Functions of the reserved space in the fuel tank: 1. Reserve some space for fuel vaporization to avoid excessive internal pressure that could rupture the tank. 2. There is a vent hole at the top of the tank. If the tank is overfilled, gasoline may overflow. In hot summer weather, this can easily lead to a fire. 3. Overfilling can block the vent hole, causing excessive pressure inside the tank, which may result in poor fuel supply or even no fuel supply. 4. Overfilling can cause gasoline to enter the cabin. Long-term inhalation of gasoline fumes, which contain multiple proven carcinogens, can lead to serious health risks, including cancer.

What does 'a wolf in sheep's clothing' mean?

It refers to vehicles that have an elegant appearance and seem no different from ordinary family cars on the surface, but their actual performance far exceeds that of regular family cars. For example, Audi's RS series models are often referred to as 'a wolf in sheep's clothing' in China, and some people vividly translate it as 'a wolf in sheep's clothing'. Below is an introduction to the Audi RS7: 1. Power: Under the hood lies a V8 engine with 600 horsepower, and 800N·m of torque that could soften an elephant. The 3.6-second 0-100 km/h acceleration feels like being kicked in the shoulder blades by a kangaroo, and the sound it emits is like that of a grizzly bear woken up early and extremely displeased. Therefore, this car is very violent. 2. Driving modes: The Audi RS7 has two driving modes, Comfort and Dynamic, which perfectly reflect its dual nature of being both 'a wolf' and 'in sheep's clothing'. In Comfort mode, the RS7 is a comfortable family commuter car with just the right throttle response, making power readily available. When switched to Dynamic mode, the RS7 reveals the side that has earned it the nickname 'a wolf', unabashedly expressing its restlessness through exhaust noise and throttle pressure.
