What is the symbol for the heater?

The heater switch symbol is generally displayed as a "thermometer" or with red and blue color markers on both sides. By rotating the knob, the red area indicates gradually increasing temperature. Automatic air conditioning allows you to set a temperature and then press the AUTO button, where the system will automatically adjust based on the interior temperature of your car. Below is an introduction to the heater: 1. Principle: The main motor drives the plunger oil pump, combustion-supporting fan, and atomizer to rotate. The oil pump delivers the inhaled fuel to the atomizer via the fuel pipeline. The atomizer mixes the atomized fuel with the air inhaled by the combustion-supporting fan in the main combustion chamber through centrifugal force, which is then ignited by the glowing glow plug. After full combustion in the rear combustion chamber, the process reverses, transferring heat to the medium—coolant—in the water jacket interlayer through the inner wall of the water jacket and the fins above. The heated medium circulates throughout the pipeline system under the action of the circulation water pump (or thermal convection) to achieve the heating purpose. The exhaust gas from the heater is discharged through the exhaust pipe. 2. Function: Heats the engine's circulating medium—antifreeze—directly transferring heat to the interior radiator and defroster, providing a heat source for cold engine starts and cabin heating.

Can I Use My Old License Plate on a New Car?

You can use your old license plate on a new car, but there are specific conditions: 1. The license plate must belong to the same owner, meaning both vehicles must be registered under the same person; 2. The registration location must be the same, for example, a plate from Shandong (Lu Q) can only be replaced with another Shandong (Lu Q) plate; 3. The type of license plate must be the same—yellow plates can only be replaced with yellow plates, blue plates with blue plates, and green plates with green plates; 4. The vehicle must be non-commercial; 5. If you have already swapped plates, you must wait one year before applying for another swap or retaining the original plate number. If all these conditions are met, you can use your old license plate on your new car.

Where is the autonomous driving feature in Mercedes-Benz?

Automatic transmission gear shift lever in Mercedes-Benz is located behind the steering wheel. By pulling it to different positions, it corresponds to different gears. Autonomous Driving Overview: Autonomous vehicles, also known as driverless cars, computer-driven cars, or wheeled mobile robots, are intelligent vehicles that achieve unmanned driving through computer systems. They have a history spanning decades since the 20th century and showed trends approaching practicality in the early 21st century. Working Process: Autonomous vehicles rely on the collaboration of artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems, enabling computers to operate motor vehicles automatically and safely without any active human intervention.

What to Do If Vehicle Fails Emission Test?

There are mainly two reasons why a vehicle's emissions fail to meet standards: 1. Poisoned Catalytic Converter: This occurs due to high sulfur content in gasoline or the use of sulfur-phosphorus antioxidant in lubricants. The gasoline and lubricants should be replaced promptly. 2. Catalytic Converter Failure: Catalytic converter failures are categorized into reversible and irreversible failures. Reversible failure happens when the catalytic converter is used beyond its service life, leading to high-temperature deactivation of the catalyst. Irreversible failure is caused by sintering or damage to the catalytic converter. Additional Information: Composition of Vehicle Emissions: The main components of vehicle emissions include carbon monoxide, hydrocarbons, nitrogen oxides, carbon dioxide, sulfur dioxide, lead compounds, and some particulate matter.

What are the characteristics of diesel engines compared to gasoline engines?

Compared to gasoline engines, diesel engines have characteristics such as higher compression ratio, better thermal efficiency, and superior fuel economy. The differences between gasoline and diesel engines are as follows: 1. Firstly, the injection method is different: conventional gasoline engines mix gasoline with air before entering the cylinder, while diesel engines directly inject diesel into the cylinder already filled with compressed air. 2. Ignition method differs: gasoline engines require spark plugs to ignite the air-fuel mixture, whereas diesel engines rely on compression auto-ignition. 3. Compression ratio varies: diesel engines generally have a higher compression ratio than gasoline engines, resulting in greater expansion ratio and thermal efficiency, leading to lower fuel consumption compared to gasoline engines. 4. Intake stroke: diesel engines draw in pure air, while gasoline engines intake a mixture of air and gasoline.

How often should the cabin air filter and engine air filter be replaced in a sedan?

The cabin air filter should typically be replaced every 10,000-20,000 kilometers or approximately once a year, while the engine air filter requires replacement around every 15,000 kilometers. Below is relevant information: 1. Conditions requiring shorter replacement intervals: The actual replacement frequency depends on the vehicle's usage conditions, driving environment, and air quality. In cases of poor environmental conditions, high humidity, excessive dust, or in smog-prone cities, the replacement interval should be appropriately shortened. Similarly, during periods of severe haze or heavy poplar fluff, the replacement cycle should also be reduced. 2. Cabin air filter location: The cabin air filter is generally located behind the glove compartment on the passenger side, though some vehicle models position it beneath the windshield's air deflector channel. Its function is to filter outside air entering the vehicle through the air conditioning system, particularly removing external dust during recirculation mode, with the primary purpose of protecting the vehicle's occupants.

Where is the sensor located on the BMW 4 Series?

The sensor on the BMW 4 Series is installed at the position where the circulating water returns to the radiator in the engine. Function of the coolant temperature sensor: The function of the coolant temperature sensor is to convert the coolant temperature into an electrical signal and input it to the ECU. It adjusts the fuel injection quantity by increasing it during low temperatures, modifies the ignition timing advance angle by increasing it during low temperatures and delaying it during high temperatures to prevent knocking, and affects the idle control valve. During low temperatures, the ECU controls the idle control valve based on the coolant temperature sensor signal to increase the idle speed. Structure of the coolant temperature sensor: The coolant level and temperature sensor consists of a temperature control section and a water level control section. It is also equipped with a pressure reduction device before the electric valve and a rotary muffler heater for heating.
