What are the shifting techniques for FAW Jiefang 12-speed transmission?

FAW Jiefang 12-speed shifting techniques: 1. When the engine reaches the appropriate speed and RPM for shifting, the gear engages smoothly. Since this type of transmission doesn't have a synchronizer, clutch operation isn't necessary for gear changes after starting. 2. If the vehicle speed and gear position don't match or if the throttle input is incorrect, the gear won't engage even with clutch operation, resulting only in gear grinding noise. 3. Shifting shouldn't be done by sound but rather by monitoring engine RPM. Start in first gear, shift to second when reaching about 10 km/h, shift to third around 20 km/h, and use fourth gear for speeds above 30 km/h.

What are the consequences of mixing engine oil with coolant?

If coolant gets mixed into the engine oil, a small amount may not cause significant issues, but a large quantity can lead to adverse effects. This can easily result in oil emulsification, disruption of the oil's structure, impaired lubrication, and consequently, accelerated engine wear, potentially leading to engine damage. It is advisable to drain the contaminated oil promptly and refill with new oil that meets the required standards. Methods for selecting coolant: The basic indicators for coolant are its freezing point and boiling point. Available in the market are coolants with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is recommended to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. Methods to determine if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to low coolant levels, although it could also be triggered by excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Inspect the water level markings on the coolant overflow tank. The normal coolant level should be between the maximum and minimum marks. If the coolant is below the minimum mark, it indicates a deficiency.

How Many Years Can a Car Generally Be Driven?

The usable lifespan of a car is not determined by its age but rather by its mileage. The government will guide the scrapping of vehicles that have reached 600,000 kilometers. Here are some methods to extend a car's lifespan: 1. Maintain good driving habits: The way a car is driven significantly impacts its lifespan. Good driving habits not only reduce wear and tear but also save fuel. Drive gently, accelerate slowly, and anticipate braking to avoid sudden stops. In cold weather, warm up the car first to allow the lubricant to circulate freely throughout the system and fully lubricate internal components. 2. Regular cleaning and weight reduction are crucial: Take care of the car's exterior with periodic washing and waxing, and don't neglect the interior. Spend time cleaning instead of just masking odors with air fresheners, and regularly vacuum the carpets. 3. Choose a trusted repair shop: Visiting different shops each time means every technician has to gradually familiarize themselves with the car, perform the same thorough inspections, identify potential issues, and then address them. This approach takes longer and may cost slightly more.

What are the functions of a fuel injector?

The fuel injector mainly consists of three parts: the starting circuit, cold fuel injector, and thermal time switch. It is a device that injects fuel into the intake manifold during cold engine starts to enrich the air-fuel mixture and improve the engine's cold start performance. The functions of the fuel injector are as follows: 1. Pressure regulation: Increase fuel pressure to 10MPa~20MPa. 2. Timing control: Control the injection timing to spray fuel and stop spraying according to the specified time. 3. Quantity control: Adjust the amount of fuel injected based on the diesel engine's operating conditions to regulate the engine's speed and power.

What is the best position to install the reversing convex mirror?

Installation position of the reversing convex mirror: The left convex mirror should be installed at the upper left corner of the left side mirror, and the right one should be installed at the lower left corner. Below are the benefits of installing convex mirrors: 1. Reduce blind spots: During daily driving, due to certain blind spots in the line of sight, it is often impossible to see some situations on adjacent roads, such as when a vehicle behind is overtaking or making a U-turn. These situations can create blind spots. Installing convex mirrors can expand the field of vision and reduce blind spots on the right rear side of the vehicle. 2. Expand the field of vision: The driver sitting in the cab usually cannot see the situation on the side and rear of the vehicle. After installing convex mirrors, the driver's viewing angle can be increased, allowing clear visibility of the rear wheels when reversing.

What to Do When Your Driver's License Points Are Not Enough?

If your driver's license points are not enough, you can use someone else's points to deduct. Below is relevant information about traffic violation point deductions: 1. Driver's License Point Reset: The cumulative scoring cycle for road traffic safety violations (i.e., the scoring cycle) is 12 months, with a full score of 12 points. It is calculated from the date the motor vehicle driver's license is initially obtained, and so on in a continuous cycle. The reset time for the driver's license points is the issuance date on the license, and the system automatically resets the points on that date each year. Starting from the "initial issuance date" of the driver's license, one year constitutes a scoring cycle, and so on in a continuous cycle. 2. Point Deduction Rules: If the points deducted for violations in a scoring cycle do not reach 12 points, the scoring system will automatically reset the points from the previous scoring cycle (after the fine is paid) at the start of the next scoring cycle.
