What is the difference between explosion-proof levels CT4 and BT4?

The differences between explosion-proof levels CT4 and BT4 are as follows: 1. Different levels: The explosion-proof level of CT4 explosion-proof motors is ExdIICT4, while that of BT4 explosion-proof motors is ExdIIBT4, with a lower protection level than CT4 explosion-proof motors. 2. Different applicable gas environments: BT4 is suitable for some conventional gases, such as methane, ethane, petroleum, hydrogen sulfide, and other common gases. CT4 can cover more uncommon and highly explosive gases, such as hydrogen at CT1 level, water gas, acetylene at CT2 level, and carbon disulfide at CT4 level. 3. Different explosion-proof levels: The explosion-proof level of CT4 explosion-proof motors is higher than that of BT4 explosion-proof motors. 4. Different applicable zones: BT4 is suitable for gas hazardous area Zone 2, with a maximum surface temperature not exceeding 135°C. CT4 is suitable for gas hazardous areas Zone 1 and Zone 2, with a maximum surface temperature not exceeding 135°C.

Are there cameras at highway exit ramps?

Usually, surveillance cameras are installed at ramp entrances. If you drive in the wrong direction on a ramp, you will definitely be caught on camera and face corresponding penalties. Here are some precautions regarding highway ramps: 1. Avoid sudden lane changes on ramps: When driving past a ramp, try to avoid chatting or laughing with others, and focus your attention on driving. Do not merge onto the highway too slowly. Many people believe that speed should be reduced when merging onto a highway, but this is a misconception. Experiments have shown that the greater the speed difference, the more severe the consequences of a collision. 2. Avoid shifting the vehicle's center of gravity while driving: Highway ramps are typically narrow, especially those with sharp turns that have significant inclines. Although highways are designed scientifically to handle such conditions, rollovers can still occur if speeds are too high or the vehicle is too heavy. 3. If you miss a ramp, proceed to the next exit: If you have already passed a ramp entrance, do not brake suddenly or reverse to avoid causing a rear-end collision. The correct approach is to continue to the next ramp and exit there.

Will running a red light on a half-closed road under construction be photographed?

Running a red light on a half-closed road under construction will be photographed as long as the traffic light camera system is functioning normally. Running a red light will result in a fine and a deduction of six points from the driver's license. When passing through construction zones, drivers should slow down and observe the traffic light conditions before proceeding through the intersection. 1. At road construction sites: There are relevant traffic signs and auxiliary roads to guide traffic. If the traffic lights are functioning normally to guide vehicles, running a red light in such conditions will be considered a violation. This is because traffic police have set up relevant signs and indicators to guide vehicles at construction sites, so it qualifies as running a red light. 2. In case of a traffic accident: The vehicle that ran the red light will bear full responsibility. Not all intersections with traffic lights have electronic cameras for photographing violations. Intersections with cameras will have warning signs, but for safety reasons, drivers should never run a red light, regardless of whether there are cameras or not, and must always obey traffic rules.

Does Keeping the Engine Running Damage the Car?

Keeping the engine running for extended periods while it remains in a high-temperature state will increase fuel consumption, causing the engine to operate under high load continuously. This can lead to gasoline leakage from the engine and even oil stains on the car chassis. If exposed to open flames, it may easily result in spontaneous combustion. Below are some key points regarding car engine maintenance: 1. Use qualified lubricating oil: For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. 2. Regularly change the oil and filter: To avoid malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level (generally up to the upper limit of the oil dipstick). Additionally, if the filter is clogged and oil cannot pass through the filter element, it may rupture the filter or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and worsening internal pollution.

What is the fuel consumption for a 1.8L displacement engine?

Fuel consumption for a 1.8L displacement engine is 6~8L. Vehicle fuel consumption is calculated based on the fuel consumed per 100 kilometers traveled (commonly referred to as 100 kilometers). For example, when people say "8 liters" or "9 liters," they mean 8 liters or 9 liters per 100 kilometers. Methods to reduce fuel consumption: Maintaining normal tire pressure levels is also a good way to reduce fuel consumption. If tire pressure is insufficient, rolling resistance will increase significantly. According to tests, if tire pressure is 2 psi (pressure unit: pounds per square foot) below the specified value, fuel consumption will increase by 1%. Additionally, misaligned or excessively worn tires may also increase fuel consumption. Related information: Oxygen sensors are prone to silicon poisoning after prolonged use. Once this occurs, the electronic fuel injection system's computer cannot obtain information about the oxygen concentration in the exhaust pipe, often resulting in a higher concentration of the air-fuel mixture in the engine and increased fuel consumption. Similarly, when there is insufficient power, the oxygen sensor and fuel injector cannot function properly, leading to a richer air-fuel mixture and higher fuel consumption. Typically, replacement is needed at 80,000 to 110,000 kilometers.
