Should the motorcycle choke normally be open or closed?

1 Answers

When the motorcycle is running normally, the choke switch should be open. Working principle of the motorcycle electronic choke: When the motorcycle engine is running, the current generated by the magneto is also connected to the internal PTC heating element via an additional lead wire. This generates heat, causing the wax thermal expansion body to expand. Through the diaphragm and liquid medium, the small piston is pushed downward, thereby driving the vertically sliding fuel control needle valve to move down and close the enrichment fuel outlet. Function of the motorcycle choke: The choke is a unique device in carburetor-type gasoline engines. It can adjust the mixture concentration to facilitate starting. Under normal circumstances, it should be kept in the open position.

Can vehicle antifreeze be mixed and topped up?

Only antifreeze of the same brand can be mixed and topped up for vehicles. Different brands of antifreeze may have varying production formulations. If mixed, chemical reactions between multiple additives are likely to occur, causing the additives to become ineffective. Methods for selecting antifreeze: The basic indicators of antifreeze are the freezing point and boiling point. The market offers antifreeze with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region. Methods to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze levels, though it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level markings on the antifreeze tank. The antifreeze level should normally be between the maximum and minimum marks. Whether the antifreeze is low depends on the markings. If the antifreeze is below the minimum mark, it indicates a deficiency.

How to Restart a Frozen Central Control Screen in Geely Vision?

Here are the methods to restart a frozen central control screen in Geely Vision: 1. Check third-party software to see if any new software has been downloaded recently. The freeze may be caused by unstable programs or insufficient memory. In this case, you need to delete some memory and uninstall related software. 2. Check the hardware to see if the screen is damaged, if there is a problem with the wiring, or if the IC and motherboard are causing the freeze. If it is a hardware problem, you need to go to a 4S store for repair or to a repair shop for inspection. 3. Check if the system needs an update to see if the car system software is not updated to the latest version, causing the display screen to freeze. If so, simply update the software version. 4. Replace the navigation device. If many methods have been tried and still do not work, you can only perform a car inspection and replace the navigation device with a new one.

Does Stepping on the Accelerator in P Gear Harm the Car?

Stepping on the accelerator in P gear does not harm the car because the power is not transmitted to the drive shaft. Unless you press the accelerator while driving and directly shift into P gear, it will not cause catastrophic damage to the vehicle. When the car is in P gear, the engine power is not transmitted to the drive shaft or the transmission. The gears inside the powertrain are only idling, so there is no need to worry about harming the car. However, when the power is not transmitted to the transmission, the engine speed will rise, and the noise will increase, resulting in a roaring sound. Additionally, the engine running at high speeds will also increase carbon buildup. The function of P gear: After shifting into P gear, the output shaft of the car is mechanically locked, thereby securing the vehicle. After the vehicle stops, the parking switch should be turned on, and then the gear should be shifted to P before releasing the foot brake to complete a normal parking procedure. However, it is also important to note that if stepping on the accelerator in P gear is done for an extended period, it can cause the engine temperature to rise rapidly, reducing the radiator's cooling efficiency. In severe cases, it may burn the big and small bearings under the piston and adversely affect the belts and gears. Therefore, it is best to avoid doing this.

What is the replacement interval for the transmission fluid in the Tiguan 1.8T?

The replacement interval for the transmission fluid in the Tiguan 1.8T is 55,000 kilometers. Below are the methods for replacing transmission fluid: 1. Gravity replacement: Use tools to loosen the nut, and the transmission fluid will automatically flow out under gravity. 2. Circulation machine replacement: Store new transmission fluid inside the circulation machine, connect the machine's pipes to the transmission's oil circuits, and under hydraulic pressure, the new fluid will push out the old fluid. This method cleans the oil circuits more thoroughly. 3. Oil pan removal replacement: This method cleans from the root, making it more thorough, and also allows for cleaning the transmission fluid filter.

How to Check the Production Date of Car Headlights?

Methods to check the production date of car headlights: To read the production date of car headlights, you can look for the stamp on the headlight. The stamp is usually located at the bottom left or bottom right corner of the headlight, and the production date can be directly seen from the stamp. Below is some relevant information about replacing headlights: 1. When selecting new headlights, you should choose the appropriate bulb model based on your vehicle, while also considering issues such as annual inspections and whether the battery can handle it. It is best to choose original equipment manufacturer (OEM) headlights. 2. Avoid touching the glass shell of the bulb directly with your hands during disassembly and installation. When installing the bulb, do not touch the glass body directly with your fingers, as even a tiny amount of oil residue on the glass can shorten the bulb's lifespan, and long-term use may even pose a risk of cracking. 3. When replacing the bulb, compare the illumination and adjust it promptly.
