Reasons why the vehicle cannot recognize the smart key: 1. The remote control has no power; 2. There are signal towers or other interference devices nearby; 3. There is a problem with the smart remote system. A smart key is a key that uses infrared signals to open one or two car doors, the trunk, and the fuel tank cap, and can also control the car's windows and sunroof. Smart keys can be divided into two parts: the entry system and the start system, but most keyless entry systems include the start function, with only a few models having the entry function. The smart entry system uses advanced RFID technology. RFID (Radio Frequency Identification) is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. The identification process does not require manual intervention and can work in various harsh environments.

What brand of tires does the original Haval H6 come with?

Haval H6 originally comes with Giti SUV520 tires. The Giti SUV520 is a high-performance tire that utilizes 3B stiffness balancing technology, combined with a reasonable configuration of shoulder tread blocks and transverse grooves, ensuring even ground pressure distribution on the tread to enhance handling stability and grip performance. Additionally, the tire features four wide longitudinal straight grooves on the tread, effectively ensuring braking performance in rainy conditions, reducing braking distance, and enabling rapid water drainage during high-speed driving. The tire employs sound balancing technology with a multi-pitch chaotic arrangement design on the tread, along with fine tread patterns, effectively reducing tread noise and improving ride comfort. Furthermore, the use of highly dispersed nano-grade silica compound materials effectively reduces rolling resistance during driving while ensuring wet road grip.

What are the effects of mixing gasoline on the engine?

Mixing gasoline can cause knocking and carbon deposits in the engine. The main difference between 92-octane and 95-octane gasoline lies in the ratio of n-heptane and isooctane. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. The higher the proportion of isooctane, the better the anti-knock performance. The selection of gasoline octane rating should follow the manufacturer's recommendation, which is usually indicated on the fuel tank cap. Under the premise of effectively eliminating knocking, lower-octane gasoline can provide better power than higher-octane gasoline. For turbocharged engines, 92-octane gasoline is typically used within the permissible fuel range, as it can achieve high torque at low speeds, reduce low-speed noise, eliminate low-speed vibrations, and maintain good anti-knock performance at high speeds.

How to Determine the Condition of Spark Plugs?

Determining the condition of spark plugs: 1. Short-circuit method: With the engine running at low speed, use a screwdriver to short-circuit between the high-voltage wire of the tested spark plug and the cylinder block, cutting off the spark plug's operation. If the engine speed significantly decreases and shakes, it indicates the spark plug is functioning well; otherwise, it is malfunctioning. 2. Temperature sensing method: After the engine reaches normal operating temperature, touch the ceramic body of each spark plug by hand. If a spark plug feels cooler, it can be judged as malfunctioning. 3. Spark gap method: Remove the high-voltage wire from the spark plug, maintaining a 5mm gap between the wire end and the spark plug terminal. If the engine's performance improves, it indicates a fault with that spark plug.
