Where is the expansion valve located on the Baojun 730?

The expansion valve of the Baojun 730 is located on the air conditioning evaporator. Meaning of Baojun 730: The expansion valve, also known as the throttle valve, is a key component of the automotive air conditioning refrigeration unit installed at the inlet of the evaporator. It serves as the boundary between the high-pressure and low-pressure sections of the automotive air conditioning refrigeration system. The expansion valve is a common component widely used in refrigeration systems. It allows medium-temperature, high-pressure liquid refrigerant to be throttled into low-temperature, low-pressure wet vapor, thereby controlling the flow rate. It is typically installed at the refrigerant inlet of the evaporator. Function of Baojun 730: The expansion valve throttles and reduces the pressure of high-pressure liquid refrigerant from the liquid storage dryer, regulating and controlling the amount of liquid refrigerant entering the evaporator to adapt to changes in the refrigeration load. It also prevents liquid slugging in the compressor and abnormal overheating at the evaporator or vapor outlet. Classification of Baojun 730: There are three main types of expansion valves (throttling devices) commonly used in air conditioning systems: thermal expansion valves, electronic expansion valves, and capillary tubes. Based on structural differences, they can also be categorized into externally balanced expansion valves, internally balanced expansion valves, and H-type expansion valves.

Where is the fuel tank vent of the Teana located?

The fuel tank vent is located on the fuel tank cap. Types of automotive fuel tanks: Based on the type of fuel, fuel tanks can be categorized into gasoline tanks and diesel tanks. Structurally, fuel tanks can be classified into crimped-edge tanks, aluminum alloy tanks, CO2 welded tanks, top-bottom butt-jointed tanks, and end-seam welded tanks. Automotive fuel tanks are mostly made by welding thin steel sheet stampings. In recent years, metal fuel tanks have gradually been replaced by plastic fuel tanks. The upper part of the tank is equipped with a fuel gauge sensor, fuel inlet and return ports, fuel filler neck, heater fuel pickup, vent, and fuel tank cap; the bottom is fitted with a drain plug; and the interior contains baffles. Some modern tanks now use a gravity valve (see the attachment for details) to replace the vent. Forms of plastic fuel tank systems: Plastic fuel tanks can adapt to more complex vehicle body structures and more compact designs, allowing for the formation of complex shapes and improving space utilization. The general manufacturing process for fuel tanks involves blanking → stamping → forming → welding → rustproof treatment.

Can You Wax a Car at -10 Degrees Celsius in Winter?

You can wax a car at -10 degrees Celsius in winter, as waxing is not season-dependent. The method for car waxing is as follows: Use tape to section off the areas that need waxing. Pour an appropriate amount of polish onto a green sponge pad. Wipe back and forth in straight lines along any scratches. After a few minutes, wipe clean with a soft cloth. Check the waxing effect after wiping. The benefits of car waxing are as follows: Waterproofing and protection against acid rain, reducing water droplet adhesion. The film can reflect some light, effectively preventing paint aging. It reduces friction between the car body and air/dust, preventing static electricity. Enhances the gloss of the paint, restoring its shine. Light scratches can be polished with car wax. Precautions for winter waxing: Waxing should be done in a clean, well-ventilated area for better results. Wax in a shaded area, as high body temperature reduces wax adhesion, affecting the outcome. Control the movement of the waxing sponge during application; both manual and machine sponges should move in straight, back-and-forth lines, not in circles, to avoid uneven wax application. Follow a top-down principle: wax the roof first, then proceed to the front and rear hoods, and the front of the car body.

Should Brake Pads Be Replaced at a 4S Shop?

When a car has been used for a certain number of years and has reached a certain mileage, the brake pads will show signs of aging and wear, at which point they need to be replaced. From the perspective of safety and quality, replacing brake pads at a 4S shop offers more assurance. 1. Replacing at a 4S Shop: The advantage of replacing at a 4S shop is that if any quality issues arise during the warranty period, you can file a warranty claim with the manufacturer. The downside is the higher cost, and for some stubborn brands, the waiting time might be longer. 2. Replacing at an External Repair Shop: The quality of brake pads replaced at external repair shops can vary, and poor-quality replacements might lead to safety issues. However, the cost of replacing parts at external shops is generally lower than at 4S shops, and you usually don’t have to wait as long. Precautions Regarding Brake Pads: 1. Inspect the brake pads every 10,000 kilometers. 2. On long downhill stretches, avoid continuously pressing the brake pedal for extended periods to prevent brake system failure due to overheating. Instead, utilize engine braking. 3. Avoid water immersion.

Can Domestic Cars Last for 15 Years?

How long a domestic car can last depends entirely on the driving habits of different individuals. The product quality varies across different price points and manufacturers. From the perspective of paint and sheet metal, although they may not match joint-venture cars, the current quality has improved by leaps and bounds compared to a decade ago. Today's domestic cars can easily reach a lifespan of ten years, and with proper use, covering over a hundred thousand kilometers is quite achievable. Exterior Inspection: Before driving, check the doors, hood, trunk, and glass condition. Inspect the car body for any damage, tilting, oil leaks, or water leaks. Engine and Various Fluids: Check the fastening condition of engine components and inspect all engine joints for oil or coolant leaks. Adjust and tighten belts as needed, and inspect the fastening of all hoses and wiring. Top up engine oil, coolant, and battery electrolyte. Tires: Check tire wear and clean the trunk. Replace tires when they approach the wear indicators. Inspect tires for bulges, abnormal wear, aging cracks, or other damage. Cleaning and Lubrication: Clean oil stains from the engine hood, door hinges, and trunk hinge mechanisms, and lubricate them. Generally, antifreeze should be replaced every 2 years during maintenance, with a thorough cleaning of the cooling system. Due to the hygroscopic nature of the braking system, brake fluid should be replaced every two years.

What are the classifications of motorcycles?

Motorcycles can be classified by purpose, structure, and model positioning. Classification by purpose: From the perspective of usage, motorcycles can be divided into commuter motorcycles, recreational motorcycles, and leisure motorcycles. Their main differences lie in the usage scenarios. Commuter motorcycles are primarily used for short-distance travel, making them suitable for daily commuting. Recreational motorcycles focus on seeking excitement, catering more to the entertainment needs of riders. Leisure motorcycles, on the other hand, emphasize relaxation and enjoying scenic views, making them ideal for short trips and medium to long-distance touring. Classification by structure: From a structural standpoint, motorcycles can be categorized into two-wheeled motorcycles and three-wheeled motorcycles. Three-wheeled motorcycles include models like the standard trike, sidecar trike, and reverse trike. Two-wheeled motorcycles, depending on their frame structure and running gear, can be further divided into categories such as standard motorcycles, scooters, underbone motorcycles, and other more specialized models. Classification by model positioning: Every motorcycle has a relatively clear positioning from the beginning of its development, which mainly comes from the brand's lineup and style. For example, the Kawasaki Ninja series is classified as a sports bike, the Z series as a street bike, the Versys series as an adventure touring bike (ADV), and the W series represents both early Japanese street bikes and current retro bikes.
