What is the working principle of a brake relay valve?

Working principle of the brake relay valve: When the brake pedal is pressed, the output air pressure from the brake valve serves as the control pressure input for the relay valve. Under the control pressure, the intake valve is pushed open, allowing compressed air to flow directly from the air reservoir into the brake chamber through the intake port, bypassing the brake valve. This significantly shortens the air filling path for the brake chamber and accelerates the air filling process. Below is an introduction to the brake relay valve: 1. Function: The relay valve is part of the vehicle's air brake system. In the braking system of heavy-duty vehicles, the relay valve serves to reduce reaction time and pressure buildup time. 2. Differential relay valve: It prevents simultaneous operation of the driving and parking systems, overlapping forces in the combined spring brake cylinder and spring brake chamber, thereby avoiding overloading of mechanical transmission components and ensuring rapid filling and exhausting of the spring brake cylinder.

What are the reasons for a car not starting due to fuel supply issues?

Reasons for a car not starting due to fuel supply issues are as follows: 1. Fuel quality issues: Remind car owners to always refuel at reputable gas stations. When traveling, you can use a gauze wrapped around the fuel nozzle to filter out impurities. 2. Dead battery: This could be due to leaving headlights on for extended periods, resulting in a drained battery, or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. 3. Incorrect gear position: When starting an automatic transmission car, the gear must be in P (Park) or N (Neutral). If it is in R (Reverse) or D (Drive), the car will not start. Some manual transmission cars may also fail to start if the clutch is not depressed.

What to Do When the At-Fault Driver Doesn't Answer Calls?

The solutions when the at-fault driver doesn't answer calls are as follows: 1. Contact the insurance company: There's no need to contact the other party directly. The accident report contains both parties' license plate numbers and the name of the insurance company. You can directly contact the other party's insurance company. If the insurance company doesn't handle the claim, contact the traffic police department handling the accident to understand the process, which might be more troublesome than directly contacting the insurance company. 2. Civil lawsuit: If none of the above methods work, you may need to file a civil lawsuit. However, this involves a longer resolution time and costs such as litigation fees and attorney fees, making it very troublesome. This method is not recommended.

How often should fuel system cleaner be added?

Fuel system cleaner should be added every 5,000 kilometers. More information about fuel system cleaner is as follows: 1. Introduction: Fuel system cleaner is a general term for cleaning agents that remove carbon deposits, gum, and sludge from fuel injectors, intake valves, cylinder walls, piston tops, and intake pipes. Using such products can significantly reduce harmful emissions from vehicle exhaust, help vehicles pass exhaust tests, restore engine power, and improve engine efficiency and fuel economy. 2. Product benefits: Removes gum and dirt from the fuel system; Saves fuel and reduces exhaust emissions; Protects engine components and effectively prevents corrosion and rust.

How to Determine the 30cm Distance Between the Car Body and the Roadside?

Methods to determine the 30cm distance between the car body and the roadside are as follows: 1. For sections with curbs: Observe the distance between the right side of the car body and the curb, and make adjustments. When the position of the right front door handle just covers the curb or is about to "touch" it, quickly straighten the car body. At this point, the distance between the car body and the curb is approximately 30cm. 2. Observe the sideline: Drive along the right sideline from the middle-right position of the engine hood. At this time, the right side of the tire is about 30cm away from the right sideline. 3. Observe the hood: Align the right 15cm of the hood center with the right sideline to ensure a 30cm distance, provided that the car body is already roughly parallel to the roadside. From the driver's position, align the position one fist-width to the right of the hood center with the sideline, then straighten the wheels and stop the car.

What do LH and RH mean in cars?

In cars, LH and RH represent left and right respectively. Here are more automotive-related terms: 1. 5V: The 'V' stands for the first letter of the English word 'valve'. Traditional car engine cylinders commonly use a 4-valve structure, i.e., 2 intake valves and 2 exhaust valves, ensuring sufficient and effective intake and exhaust, which is beneficial for increasing engine speed to achieve maximum power. The 5-valve technology has been widely adopted by foreign automotive companies, and the recently launched 'Bora' in China already employs this technology, featuring 3 intake valves and 2 exhaust valves. 2. ABS: This is the abbreviation for 'anti-lock-brake-system', translated in Chinese as 'anti-lock braking system'. It is a safety brake control system with advantages such as anti-skid and anti-lock. Cars without ABS may lock the wheels when the driver slams the brakes in an emergency, leading to dangerous situations like skidding, deviation, or loss of steering control due to the vehicle's momentum. 3. GPS: Short for Global Positioning System, its main functions include anti-theft, anti-hijacking, and navigation.
