Controller damage generally manifests as weak car starting and difficulty in pushing the car. Below are the specific causes of controller damage: 1. Power device failure: Damage to power devices is usually caused by motor failure; poor quality of the power device itself or insufficient rating; improper installation or vibration loosening; motor overload; damage to the power device drive circuit or unreasonable parameter design. 2. Damage to the internal power supply of the controller: Damage to the internal power supply of the controller is generally caused by a short circuit in the controller's internal circuit; a short circuit in peripheral control components; or a short circuit in external wiring.

Where is the windshield washer fluid filler port located on the Sylphy?

The windshield washer fluid filler port on the Sylphy is located at the lower left corner of the engine compartment. The filler port is marked with a symbol resembling a windshield washer spray. Simply open the cap to add the fluid. Automotive windshield washer fluid: Windshield washer fluid, commonly referred to as glass water, is primarily composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. It can be categorized into solid and liquid forms, offering both cleaning and antifreeze properties. Most commercially available windshield washer fluids are blue in color, and their cleaning effectiveness varies. For instance, washer fluids sold in northern regions contain special antifreeze components to prevent freezing under low-temperature conditions. Precautions when adding windshield washer fluid: When adding the fluid yourself, avoid filling it to the brim. If the spray nozzles are misaligned, you can adjust their position using a needle. Steps to add windshield washer fluid: Engage the car's handbrake to prevent the vehicle from rolling while adding the fluid. Then, locate the front hood release switch on the left side of the car and ensure it can be opened. After lifting the hood, find the windshield washer fluid filler port. Add an appropriate amount of fluid, observing the fill line—avoid overfilling and stop once the fluid reaches the marked level.

Why was the Baojun 310 discontinued?

Baojun 310 was discontinued mainly due to low market sales, prompting the manufacturer to halt production and eventually withdraw it from the market completely. Here are the relevant details: Baojun 310: The Baojun 310 is a compact hatchback launched by SAIC-GM-Wuling on September 8, 2016. It was equipped with a 1.2L engine paired with a 6-speed manual transmission, resulting in a generally sluggish start. In 2017, an automatic variant was introduced, featuring a 1.5L naturally aspirated engine paired with a 5-speed automated manual transmission. Reasons for declining sales: Part of the reason was the incomplete safety features of the Baojun 310, but the larger factor was the emergence of numerous entry-level compact SUVs in the market at the time. These SUVs were priced similarly to compact cars but offered better space and performance, leading more consumers to gradually opt for compact SUVs.

What is the fuel tank capacity of the 2013 Buick Excelle in liters?

2013 Buick Excelle has a fuel tank capacity of 60 liters, which is the officially announced data. The 2013 Buick Excelle uses 92-octane gasoline, with a fuel consumption of 6.6 to 7.6L per 100 kilometers. A full tank can cover a distance of 789 to 909 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level at all times. Generally, the fuel level is observed through the fuel gauge in the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. In actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is measured from the bottom of the tank to the safety limit. There is still some space from the safety limit to the tank opening, which is reserved to allow the fuel to expand when the temperature rises without overflowing. If the fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

What are the causes of power module failure in the Excelle?

The causes of Excelle failure are parameter abnormalities and usage faults. When the power input voltage is too high or the load is less than 10% of the rated load, the power module will fail; when the power output voltage is too low, the voltage drop of the anti-reverse diode at the input end is too large, or the input filter inductance is too high, the power module will also fail. When the above faults occur, it is necessary to go to a 4S shop for timely repair, and do not replace the power module by yourself. Introduction to power modules: A power module is a power supply that can be directly mounted on a printed circuit board. Its characteristic is that it can provide power for application-specific integrated circuits (ASIC), digital signal processors (DSP), microprocessors, memories, field-programmable gate arrays (FPGA), and other digital or analog loads. Generally, such modules are called point-of-load (POL) power supply systems or point-of-use power supply systems (PUPS). Modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communication fields, as well as automotive electronics, aerospace, etc. The role of power modules: Power modules are one of the voltage conversion devices. Their main function is to convert between AC and DC. In addition, they have the advantages of easy maintenance, flexible design, cost and time savings, high power, high efficiency and high reliability.
