What Are the Reasons for a Car Air Conditioner Not Working?

What type of suspension does the Haima M6 use?

Most front-transverse engine vehicles use MacPherson front suspension. Since the lateral space in the engine compartment of front-transverse engine cars is quite limited, there is naturally no extra space to install structurally complex independent suspension. 2. The rear suspension employs a multi-link independent suspension. Multi-link independent suspension: This is a structurally complex suspension with relatively high costs. This type of suspension is an improved version of the double-wishbone suspension, where the two wishbones of the double-wishbone suspension are replaced with individual links. Double-wishbone suspension is a structurally complex independent suspension, consisting of left and right wishbones with a connecting rod between them.

Can Adding Fog Lights Pass the Annual Vehicle Inspection?

Adding fog lights can pass the annual vehicle inspection. Here are the reasons why adding fog lights is permissible: 1. Vehicles without fog lights have reserved positions for installing fog lights from the factory. 2. Installing fog lights is not considered an illegal modification (of course, if certain lights that affect other vehicles' driving are installed in the fog light reserved positions, they may not pass the annual inspection). 3. However, for safety reasons, you can consult the vehicle management office or apply to change the vehicle's driving license and take a new photo after installing the fog lights. Here are the functions of adding fog lights: Installing fog lights is mainly to improve driving safety in rainy and foggy weather. During rainy and foggy days, visibility is low, and the driver's line of sight is limited, making driving more dangerous. Fog lights have high power and strong penetration, so adding fog lights can significantly increase the driving distance and improve visibility in rainy and foggy conditions.

Why Are Used Luxgen Cars So Cheap?

Because Luxgen has an extremely low resale value. Below are relevant introductions about used cars: 1. Introduction to used car residual value rate: When buying or selling used cars, it's essential to understand a crucial metric - the residual value rate of used cars. Commonly referred to as vehicle depreciation rate, it indicates how well a car retains its value. After several years of use, how much a car is worth in the market depends on its residual value rate; the higher the rate, the more valuable the used car. To understand a car's residual value rate, several factors must be considered: whether the car has sufficient market presence, if its color is mainstream, the brand of the vehicle, and the convenience of post-purchase maintenance, among others. 2. Precautions when selling a used car: It's crucial to sell the vehicle before its insurance expires; otherwise, an additional insurance cost will be incurred during the transaction. Additionally, pay attention to the replacement cycle of spare parts.

Why doesn't the new Focus automatic transmission move when shifted into reverse?

Check whether the gear is properly engaged. If there are no operational issues, it should be taken for repair. Below is relevant information about automatic transmissions: 1. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, the more gears there are, the more fuel-efficient the transmission. 2. Driving Tips: For manual transmission vehicles, higher RPMs should be used when shifting gears. The engine is designed to operate at higher RPMs, and various components' dynamic balance and rotational inertia parameters are also designed with high RPMs in mind. If the engine operates for extended periods under non-optimal conditions, internal components' load and wear will naturally increase, leading to frequent shaking and knocking, which can affect the engine's lifespan. Choosing 3000 RPM as the shift point ensures that after shifting, the RPMs drop to around 2300, keeping the engine within a healthy operating range.

What is the Difference Between Car Headlights with and Without Lenses?

Difference between car headlights with and without lenses: 1. Some are xenon headlights. They can refract light over long distances, and lens-equipped headlights adjust the light distance according to the car's height fluctuations. 2. After installing lenses, the headlights have better light concentration and become brighter. Below is relevant information about headlight lenses: 1. Essentially, a headlight lens is a convex lens, which has a focusing effect. Parallel light rays refracted by a convex lens can converge at a single point. Similarly, if we place a light source at its focal point, the convex lens can transform it into parallel light. This is the principle behind headlight lenses—using a reflector to focus the light from the bulb at the lens's focal point, which then disperses the light evenly. Such headlights illuminate the road surface very uniformly. 2. The structure of lens headlights determines that their utilization of the bulb's light is not as efficient as that of reflectors. Since lenses alter the path of light through refraction, to achieve a more uniform and perfect light pattern, the incident light must undergo certain processing. Therefore, there is actually a shading mechanism between the lens and the bulb. When the low beams are on, the shader blocks part of the headlight's light in a pre-designed shape, meaning not all the light emitted by the bulb reaches the road surface.

Why Does the Engine Malfunction Light Stay On After Refueling?

After refueling, if the engine malfunction light stays on, it indicates the use of substandard fuel. During the combustion process in the engine, substandard fuel with high impurities and low combustion efficiency can leave residues and unburned fuel in the combustion chamber, occupying space and triggering the engine malfunction light. Solution: Promptly drain the substandard fuel and clean the fuel tank and fuel lines. After cleaning, replace with high-quality fuel. Besides fuel quality, other reasons that can cause the engine malfunction light to stay on include: Sensor Malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors, when damaged, poorly connected, or interrupted, prevent the car's ECU from accurately obtaining engine data, leading to the engine malfunction light. Poor Mixture Combustion: Poor combustion of the air-fuel mixture can cause engine carbon buildup or knocking. Monitored by the oxygen sensor and reported to the ECU, this triggers the malfunction light. Issues like faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines can lead to poor mixture combustion. Turbocharger Issues: Problems with the intake boost pipes or turbocharger can also trigger the engine malfunction light. The most common issue is turbocharger damage, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If the car's intake system is compromised, it can lead to clogged engine pipes, and in severe cases, trigger the engine malfunction light. A dirty air filter that isn't cleaned regularly can cause intake issues. Exhaust Problems: Exhaust system faults can also activate the engine malfunction light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings, with the catalytic converter being the most frequent issue. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily cause catalytic converter failure. Anti-Theft System Fault: If the car's electronic anti-theft system malfunctions or the anti-theft controller doesn't match the engine's electronic controller, the anti-theft system can prevent the engine from operating normally, also triggering the engine malfunction light.
