Burning Smell from Car Air Conditioner

The reasons for a burning smell when the car air conditioner is turned on are as follows: Mold has developed on the surface of the heat exchanger fins. Below is a related introduction to car air conditioners: 1. Compressor: Driven by the engine, it continuously draws in the low-temperature and low-pressure refrigerant vapor generated by heat absorption and vaporization in the evaporator, compresses it to form high-temperature and high-pressure refrigerant vapor, and discharges it to the condenser, creating high-pressure conditions for the refrigerant to continuously condense and release heat in the condenser. At the same time, it overcomes the circulation resistance of the refrigerant in the refrigeration circuit. 2. Condenser: Releases the heat contained in the high-temperature and high-pressure refrigerant vapor discharged by the compressor to the outside air flowing through the condenser, and condenses the refrigerant vapor into refrigerant liquid with a certain temperature. Most condensers are located in front of the radiator at the front of the car and are cooled by the cooling fan and the oncoming airflow generated by the car's movement.

What needs to be replaced in a car during winter?

Here are the items that need to be replaced in a car during winter: 1. Coolant: Modern coolants are designed for year-round use. However, if the coolant has been replaced, it's important to ensure it meets the winter temperature requirements of the driver's local area. If it doesn't, replace it as soon as possible to avoid damage to the radiator and engine. 2. Engine oil: Choose engine oil suitable for winter. The viscosity of the oil is a key factor, as different oils have different viscosities and are suited to different environments. Using the wrong oil can increase component wear and fuel consumption. 3. Tires: The phenomenon of thermal expansion and contraction also affects tires, making them more brittle and reducing their friction coefficient. Therefore, it's advisable to use winter or snow tires in harsh weather conditions. 4. Brake pads: If the thickness of the brake pads is insufficient, they should be replaced immediately. Winter conditions, such as icy roads, can pose safety hazards, making effective braking crucial.

How to Calculate Horsepower for Diesel Engines?

1 horsepower equals 0.735 kW. To calculate horsepower, you can directly divide the power by 0.735. Power is an important performance parameter of an engine. The greater the power, the stronger the acceleration performance of the vehicle, but the higher the fuel consumption. Here is some related information: 1. Origin of Diesel Engines: A diesel engine is an engine that burns diesel fuel to release energy. It was invented by the German inventor Rudolf Diesel in 1892. To commemorate this inventor, diesel is represented by his surname "Diesel," and the diesel engine is also called a Diesel engine. 2. Principle of Diesel Engines: When the piston approaches the top dead center, the fuel injector of the fuel supply system injects fuel into the cylinder combustion chamber at extremely high pressure within a very short time. The diesel forms fine oil particles, mixes with high-pressure and high-temperature air, and the combustible mixture ignites spontaneously, expanding violently to produce explosive force, pushing the piston downward to perform work. At this point, the temperature can reach 1900-2000°C, and the pressure can reach 60-100 atmospheres. The torque generated is very large, so diesel engines are widely used in large diesel equipment.

Where is the air conditioning filter located in the Tiguan L?

The air conditioning filter in the Tiguan L is located under the glove compartment on the passenger side. To replace the air conditioning filter, you need to remove the glove compartment and open the cover of the air conditioning filter to access it. There are two types of air conditioning filters available in the market: one with activated carbon and one without. Typically, vehicles use air conditioning filters with activated carbon. In terms of appearance, the Tiguan L maintains a design similar to the overseas standard Tiguan model, featuring a clean and straightforward overall style. Compared to the standard wheelbase model, it includes additional chrome decorative elements, and the C-pillar design has been modified. Regarding dimensions, the Tiguan L measures 4712 mm in length, 1839 mm in width, and 1673 mm in height, with a wheelbase of 2791 mm.
