What are the words called that are stuck on the back of a car?

What does 'Yaxiang' mean?

Yaxiang refers to the transmission. Literally, it means the transmission is full of 'teeth', with gear teeth meshing to drive the rotation. The transmission mainly refers to the vehicle's gearbox, which is divided into manual and automatic types. A manual transmission primarily consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT), on the other hand, is composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque changes through hydraulic power transmission and gear combinations. Main functions of the transmission: Changing the transmission ratio to expand the range of torque and speed variation of the driving wheels, adapting to frequently changing driving conditions while allowing the engine to operate under favorable conditions. Enabling the vehicle to reverse while keeping the engine's rotation direction unchanged. Utilizing neutral gear to interrupt power transmission, facilitating engine start-up, gear shifting, and power output.

Why is the engine still hot after the car has been parked for 6 hours in summer?

When a car engine is running, it generates a large amount of heat. Ventilation system: Therefore, ventilation systems and cooling devices are designed to dissipate the high temperature inside the engine through coolant circulation, while engine oil lubrication also helps reduce heat generation. Additionally, the rapid operation of the fan can also help dissipate the engine's temperature. Temperature alarm: To better monitor the engine's temperature and working condition, a temperature gauge or alarm is designed. If the engine's operating temperature exceeds the manufacturer's designed temperature, an alarm will be triggered, indicating poor engine working conditions or the need for inspection and maintenance.

What is Automotive Exhaust Catalytic Reduction Technology?

SCR stands for "Selective Catalytic Reduction" technology, which is a method for treating diesel engine exhaust. Technical Approach: The technical approach involves first addressing the particulate emissions from diesel engines through in-engine purification technologies such as optimizing in-cylinder combustion and reducing oil consumption, and then using an SCR after-treatment device to reduce NOx emissions from the engine. International Standards: Currently, the catalysts used internationally mainly include V2O5/WO3(MoO3)/TiO2 and other vanadium-containing and metal-based zeolite catalysts. Zeolite catalysts are known for their excellent low-temperature characteristics and high conversion efficiency at high space velocities. Vanadium-based catalysts, due to their internationally recognized high conversion activity and certain resistance to SO2 poisoning, have become the commonly used catalysts.

Is an Oil Temperature of 97 Degrees Normal?

An oil temperature of 97 degrees is normal. The normal operating temperature of engine oil is generally between 70 to 90 degrees Celsius, with some localized areas being slightly higher, but it typically does not exceed the coolant temperature. Effects of excessively high oil temperature: It can impact certain components of the vehicle, especially those far from the radiator or with weaker structures. Prolonged exposure to high temperatures can easily cause damage or even complete failure. It also affects the viscosity of the oil, leading to severe wear on some engine parts (due to oil film breakdown), and in extreme cases, can cause cylinder scoring or bearing seizure. How to check oil temperature: If the vehicle has an oil temperature sensor, you can use a diagnostic scanner to read the data. If not, you can only estimate it indirectly through the coolant temperature.

What are the models of small off-road vehicles?

Small off-road vehicles include models such as Baojun 510, Mitsubishi ASX, Dodge Caliber, Nissan Qashqai, and Jeep Renegade. Definition of off-road vehicles: Vehicles suitable for harsh road conditions and off-road driving. They are designed to handle challenging environments like steep slopes and water crossings. Off-road vehicles typically feature four-wheel drive, with chassis and suspension systems distinctly different from regular sedans. Classification of off-road vehicles: Small off-road vehicles, such as Mitsubishi ASX, Dodge Caliber, Nissan Qashqai, and Jeep Renegade. Medium off-road vehicles, like Mitsubishi Pajero, Toyota Prado, Hyundai Santa Fe, Great Wall Haval, and Mercedes-Benz GLK. Large off-road vehicles, such as Toyota Land Cruiser, Land Rover Discovery, and Jeep Grand Cherokee. Professional off-road vehicles, including Mercedes-Benz G-Class, Land Rover Defender, Jeep Wrangler, Hummer H1, and Mercedes-Benz Unimog.

What are the symptoms of a damaged temperature control switch in a car's air conditioning evaporator box?

Car air conditioning evaporator box temperature control switch damage performance is the electronic fan does not work. Electronic fan: When the engine coolant reaches the set temperature and needs to start the electronic fan, the electronic fan does not work. When the engine coolant does not reach the set temperature and does not need to start the electronic fan, the electronic fan will still turn on and keep working until the battery is drained. Engine: High engine coolant cannot dissipate heat, which will cause the water temperature to continue to rise. When it rises to a certain temperature, it will cause engine cylinder pull, cylinder head deformation, and finally the engine will automatically shut down and fail to start.
