When upshifting and accelerating in a heavy truck, you can shift gears by releasing the throttle momentarily without using the clutch. However, during deceleration, it becomes difficult to control the engine speed and driveshaft speed, so it is recommended to use the clutch for shifting operations. Here are the relevant details: 1. Features: The FAW J6 platform's engine, transmission, and drive axle—the three major assemblies—have reached international standards, setting a new benchmark for the development of commercial vehicles in China. The core power of the 2490 series is the independently developed 6DN and 6DL engines, which meet international standards, with power ranging from 280 to 460 horsepower. Among them, the 6DN engine is one of the largest displacement and highest torque engines in China. 2. Main Power Configuration: The 2250 series primarily features engines introduced from Germany's DEUTZ, with power ranging from 130 to 280 horsepower. The transmission is the FS10209, jointly produced by FAW and the U.S.-based EATON. The drive axle is China's largest φ500 single-stage reduction axle and φ485 through axle, independently developed by FAW based on Nissan Diesel technology, with an optional self-developed φ300 wheel-side reduction axle.

Where is the PCV valve located on the Wuling Hongguang?

The PCV valve of the Wuling Hongguang is located near the rear side of the throttle body in the engine compartment. Below are the relevant details: 1. Composition: The PCV valve consists of a valve body, valve, valve cover, and spring, and cannot be disassembled. Its main functions are: to direct gases from the crankcase into the intake manifold via the PCV valve, with a small amount of air entering the intake manifold directly from the air filter through the PCV valve. This prevents icing at the throttle, incomplete combustion, and worsening emissions. It also prevents exhaust gases from entering the atmosphere and prevents engine oil from deteriorating. 2. Principle: The PCV valve is a metering control valve installed between the crankcase ventilation system and the intake system. The PCV valve is controlled by vacuum and regulates the flow of oil vapor from the crankcase ventilation system into the intake system. The flow rate is higher when the engine is running at high speeds compared to low speeds. Additionally, when engine backfire occurs, the PCV valve should cut off ventilation to prevent crankcase explosion.

Will Rusty Brake Discs Cause Abnormal Noises?

Abnormal noises may occur. When brake discs are severely rusted, normal braking cannot achieve the ideal effect of grinding off the rust. Severe rust on the brake discs can cause an uneven surface, leading to issues such as steering wheel vibration and abnormal noises when braking. Below are the reasons why rusty brake discs may produce abnormal noises: 1. Slight rust on the brake disc surface: This can be removed by continuous braking while driving, and no special treatment is needed because a small amount of rust on the brake discs will be worn off by braking during vehicle operation. If the rust is more severe, it may cause vibrations or shaking during braking, such as brake pad vibration, steering wheel vibration or shaking, or body vibration. Of course, this is under the premise of ensuring safety and not affecting public traffic. While driving, gently apply the brakes to let the friction between the brake pads and the brake discs 'polish' the surface. 2. Severe rust on the brake discs: When there is a significant amount of rust, it can cause an uneven surface on the brake discs, leading to noticeable body vibrations during braking. The driver can clearly feel abnormal sensations in the brake pedal, steering wheel, and body. In such cases, it becomes difficult to remove the rust, and even if 'polishing' is attempted, it may result in abnormal wear of the brake pads and continued vibrations. Therefore, it is recommended to perform maintenance on the brake discs every two months to prevent excessive rust development.

What insurance is needed for compensation if a car is flooded?

To get compensation for a flooded car, you need to purchase vehicle damage insurance. Here are the specific details about vehicle damage insurance: 1. Regulations: Damage to a car caused by natural disasters like flooding falls under the coverage of vehicle damage insurance. During the insurance period, the insurer is responsible for compensating the direct losses of the insured vehicle caused by natural disasters, as stipulated in the insurance contract. This is within the scope of vehicle damage insurance liability. Compulsory insurance does not provide compensation. 2. Proportion: In cases of natural disasters and extreme weather conditions, vehicle damage insurance typically has a deductible of around 30%, meaning the insurance company compensates for 70% of the loss amount.

Will the brake light drain the battery if it stays on?

Yes. The power consumption of the brake light is relatively high, and the impact is quite noticeable. The reason the brake light stays on after the engine is turned off is due to a faulty brake switch. Here are the relevant details: 1. Main function: The primary role of the brake switch is to control the rear brake lights. When you press the brake pedal while driving, the brake switch is activated, causing the connected brake lights to illuminate. This alerts drivers behind you to your vehicle's status, helping to prevent rear-end collisions and other accidents. 2. Excessive wear: Over time, brake pads wear down and age. As the mileage increases, the thickness of the brake pads decreases. If the thickness of the brake pads falls below one-third of the original thickness, it can lead to brake failure or reduced performance, and may also cause the brake light to stay on continuously.
