How to adjust the ignition timing of Weichai engine?

Weichai ignition timing adjustment method is as follows: 1. First align the scale line, generally align to 10 degrees. 2. Determine whether the exhaust rocker arms of cylinder 1 and cylinder 2 are fully depressed. 3. Align the fuel pump scale (the scale line of the fuel pump indicates fuel injection for cylinder 1). Relevant information about ignition timing is as follows: 1. Ignition timing refers to the angle between when the piston reaches top dead center and when ignition begins. Professionally, it is called ignition advance angle. 2. If ignition occurs too early, detonation will occur; if too late, knocking will occur, the engine will overheat, and mechanical efficiency will decrease. Therefore, there should be an optimal ignition advance angle, which means adjusting the ignition timing.

What to Do When Water Gets Inside the Headlight?

For relatively minor cases of water inside the headlight, there is no need to worry too much. After the headlight is turned on for a while, the moisture will evaporate and exit through the vent pipe. Disassemble it, open the headlight cover, and after drying, check the surface of the headlight for any damage or potential leakage points. When water gets inside the headlight, never attempt to bake the headlight to dry it, as this can easily damage the headlight since its exterior is made of plastic.

What should be paid attention to when a car is not used for a long time?

When a car is not used for a long time, it is necessary to wash the car thoroughly before parking, and then apply a sealant or wax to the body, which helps prevent the paint surface from being corroded and oxidized. Then choose a suitable parking location. If the parking time is short, waxing is sufficient; if the time is longer, it is recommended to cover the car with a car cover. When a car is parked for a long time, the tires will suffer significant damage. It is essential to choose a flat ground for parking. Otherwise, if parked on uneven ground for a long time, the tires may deform due to uneven force. Before using the car again, carefully check whether the tires are deformed or cracked, and also check whether the tire pressure is normal, as the tires will slowly lose air. If the car is parked for a long time, there is no need to refuel temporarily. Keep a small amount of fuel in the tank to avoid excessive water in the tank due to humid weather. A high water content in the tank can easily cause many problems, especially in places where ethanol gasoline is used, so extra attention should be paid. It is recommended to use a water remover regularly. In addition, the car battery will discharge on its own. If the car is not used for a long time, the battery may lose power, and it may not start when ignited again. You can charge the car battery regularly, start the car every 1-2 weeks and let it run for 5-10 minutes, or you can disconnect the negative terminal of the battery to minimize power consumption.

How to Solve the Problem of Oil Burning in Focus?

Cold engine oil burning but normal after warming up, this phenomenon is caused by aging valve stem seals, and replacing the valve stem seals can solve the problem. Hot engine oil burning indicates poor sealing of the piston rings. The solution is to remove the oil pan and replace the piston rings. In addition, prevent contact between water, air, acidic harmful gases and parts; buffer the pressure rise at the engine cylinder port; flush the dirt generated on the working surfaces of parts.

What to Do When Cruise Control Fails?

For automatic transmission vehicles, shift the gear lever to "N" (Neutral), while for manual transmission, simply return to neutral. This is because the vehicle's transmission is not entirely electronically controlled. If the cruise control malfunctions and neither the brakes nor the transmission can be operated, one can resort to running out of fuel to achieve the goal of stopping the vehicle. The prerequisite is that the speed difference between the two vehicles should not be too large. For example, if the vehicle ahead is traveling at 60 km/h, it is crucial not to collide under such circumstances.
