What is a C1M driver's license?

C1M is a combined driver's license that merges the C1 and M licenses. Since each driver can only hold one driver's license, when adding permitted vehicle types to an existing license, the two categories are combined into a single license, resulting in this designation. Holding this license allows the driver to operate vehicles permitted under both the C1 license and the wheeled self-propelled machinery license, including cars, tire cranes, road rollers, tractors, harvesters, and specialized construction machinery. Driver's license classifications: Motor vehicle driver's licenses are divided into 16 categories: A1, A2, A3, B1, B2, C1, C2, C3, C4, C5, D, E, F, M, N, and P. C1 driver's license: The C1 driver's license is one type of motor vehicle license. The permitted driving scope for a C1 license includes small and micro passenger vehicles, light and micro cargo vehicles; light, small, and micro specialized operation vehicles; and small passenger vehicles with seating capacity of 9 or fewer people.

How to Deal with Frost on the Windshield in Winter Mornings?

Frost on the windshield can be removed using the defogging function of the car's air conditioning. The methods are as follows: 1. After the engine warms up, turn on the warm air from the air conditioning, activate the car's defogging switch, and direct the airflow toward the windshield surface to quickly disperse the frost. It is best not to use the recirculation mode at this time, and try to minimize the temperature difference between the inside and outside of the car to prevent fog from forming again. 2. Adjust the interior temperature to match the outside temperature as closely as possible, eliminating interior fog and allowing the frost to melt quickly. 3. Apply a thin layer of glycerin or alcohol to the windshield to prevent frost formation for a short period. Alternatively, mix dishwashing liquid with water in a 1:10 ratio, pour it into a spray bottle, and apply a thin layer to the inside of the windows. Once dry, this will effectively prevent fogging for a while. Finally, if frost forms on the windshield, stop the car to deal with it and wipe it clean with a dry towel. Avoid driving while attempting to remove frost or wiping it while driving to ensure road safety.

How Many Kilometers Can a Sedan Travel on a Full Tank of Gas?

Generally, it can support driving around 600 kilometers, and not less than 500 kilometers. The range of civilian vehicles with a full tank is all above 500 kilometers. Small cars have a fuel tank capacity of 35-45 liters, while mid-sized cars have a fuel tank capacity of around 55-75 liters. With a full tank, they can all travel approximately 500 kilometers. Below is the relevant introduction: 1. Driving range: The driving range of a car is directly related to the amount of fuel. Private cars have fuel tanks of varying sizes, mainly depending on the engine displacement and the size of the fuel tank. A car with a 2.0-liter displacement consumes about 10 liters of fuel per 100 kilometers, and the fuel tank size is 60-70 liters. Based on the above data, it can travel 600-700 kilometers. 2. Load capacity: Considering factors such as the economic efficiency of load capacity, installation space, displacement, and fuel consumption, most cars are configured with a fuel tank capacity that allows for a mixed-road driving range of 500 kilometers. Typically, cars with a 1.6-1.8-liter displacement have a fuel tank capacity of 40-50 liters, while those with a 2.0-2.4-liter displacement have a capacity of around 50-60 liters.

What is the refrigerant currently used in air conditioning?

Currently, there are two main types of refrigerants used in automotive air conditioning systems: R12, which is non-environmentally friendly, and R134a. The selection criteria for refrigerants are as follows: 1. Consider the type of compressor. Different refrigeration compressors operate on different principles. Positive displacement compressors increase pressure by reducing the volume of refrigerant vapor, typically selecting refrigerants with high refrigeration capacity per unit volume. 2. Consider the refrigeration temperature requirements. Depending on the refrigerant temperature and cooling conditions, high-temperature (low-pressure), medium-temperature (medium-pressure), or low-temperature (high-pressure) refrigerants are chosen. Generally, the standard evaporation temperature of the selected refrigerant should be at least 10°C lower than the refrigeration temperature. The selection should also account for the cooling conditions and operating environment of the refrigeration system. The operating condensing pressure should not exceed the safety limits specified for the compressor. Automotive air conditioning systems can only use outside air as the cooling medium, and factors such as ambient temperature, wind speed, solar radiation, and heat radiation frequently change, necessitating the use of high-temperature (low-pressure) refrigerants. In the past, R12 was commonly used, but now R134a is predominantly selected. 3. Consider the properties of the refrigerant. Based on thermodynamic, physical, and chemical properties, choose refrigerants that are non-toxic, non-explosive, and non-flammable. The selected refrigerant should have good heat transfer, low resistance, and compatibility with materials used in the refrigeration system. 4. Consider environmental requirements. The refrigerant must comply with national environmental regulations.
