This phenomenon is caused by moisture on the display. Below is an introduction to car displays: 1. Overview: The main uses of in-car displays include adding a rearview camera for reversing or for advertising on buses, subways, trains, etc. The mainstream products on the market typically come with features such as TV, external speakers, SD card reading, USB, etc. 2. Specifications: Basic specifications of in-car displays must include dust and shock resistance. In terms of temperature, they must be able to withstand extreme temperature differences ranging from -30°C to 85°C, or even up to 120°C. This is because the liquid crystal in LCD panels can freeze in low-temperature environments, leading to display malfunctions or complete failure.

What to Do When a Motorcycle Won't Start After a Month of Inactivity?

Solutions for a motorcycle that won't start after being unused for a month: 1. Check if there is a spark from the spark plug high-voltage wire. If there is a spark, it is normal; if not, the ignition system needs repair. 2. Check if there is fuel in the carburetor. Close the fuel tank switch and loosen the drain screw at the bottom of the carburetor to see if there is fuel inside. Lack of fuel can also prevent starting, so add an appropriate amount of fuel if needed. 3. Check if the carburetor choke operates normally. If the choke is faulty, it requires repair. Motorcycles, driven by gasoline engines and steered by handlebars to turn the front wheel, are lightweight, flexible, and fast, widely used for patrols, passenger and cargo transport, and also serve as sports equipment.

How Many Kilometers Should a Fuel Filter Be Replaced?

Generally, externally mounted fuel filters require replacement every 20,000 to 30,000 kilometers, while filters integrated with the fuel pump should be replaced every 80,000 to 100,000 kilometers. Below are potential issues that may arise from not replacing the fuel filter for an extended period: 1. Severe decrease in vehicle power and engine shaking while driving: A clogged fuel filter can result in low fuel supply pressure, reducing engine power. It may also lower the fuel injection pressure, leading to a lean air-fuel mixture, incomplete combustion, and symptoms like engine shaking during driving. 2. Idle shaking: As the fuel filter begins to clog gradually, it can cause insufficient fuel pressure and supply, leading to shaking at idle.

What does a 4.0td car mean?

4.0td car means a turbocharger device is added to the engine with displacement. It represents a diesel engine with turbocharging, where the turbocharger can alter the engine's air intake, allowing more complete combustion of fuel in the cylinders, thereby increasing the engine's output power. Compared to engines of the same displacement, it has advantages such as higher output power, lower fuel consumption, and better environmental performance. Here, 'L' stands for the largest unit of volume, referring to the engine's displacement. Below is extended information about turbocharging: 1. Turbocharging (Turbo): Turbocharging is abbreviated as Turbo. If you see Turbo or T at the rear of a car, it indicates that the vehicle is equipped with a turbocharged engine. A turbocharger is essentially an air compressor that increases air intake by compressing air. 2. Principle: It utilizes the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber, which in turn drives a coaxial impeller. The impeller compresses air delivered from the air filter pipe, pressurizing it before it enters the cylinders. As the engine speed increases, the speed of exhaust gas expulsion and the impeller rotation also increase, allowing the impeller to compress more air into the cylinders. The increased pressure and density of the air enable the combustion of more fuel, and correspondingly increasing the fuel amount can enhance the engine's output power.
