Road expansion joints should be installed every 10 to 15 meters, with the width controlled between 4 to 5 millimeters. Here is relevant information: 1. Purpose: The primary reason for installing expansion joints on roads is to prevent significant stress caused by thermal expansion and contraction, which could lead to cracks in the pavement. Similarly, buildings also require expansion joints for the same reason, mainly to prevent certain structural components from being affected by climate changes. 2. Precautions: During construction, the contractor must first hoist the expansion joints into place, ensuring the road surface is level. It is also necessary to verify whether the expansion joints meet the factory certification standards, and based on the user manual, mark and cut according to the bridge specifications.

What Causes Engine Vibration in Wuling Hongguang?

Wuling Hongguang engine vibration is caused by: 1. Poor operation of the exhaust gas recirculation valve; 2. Incorrect timing due to chain elongation without high-temperature exposure; 3. Issues with the throttle or cylinder pressure (new vehicles won't have this problem, older vehicles may need cleaning or replacement); 4. Faulty oxygen sensor operation, mainly because this vehicle's oxygen sensor magnetic group ring is installed on the crankshaft and may vibrate when worn. The Wuling Hongguang is SAIC-GM-Wuling's first self-developed crossover product between commercial vehicles and passenger cars, featuring a streamlined exterior design and a versatile, practical spacious cabin.

How to Bleed Air from the BMW X5 Coolant System?

Method for bleeding air from the BMW X5 coolant system: 1. Press the brake pedal of the BMW X5 to prepare for engine start; 2. Press the one-touch start button of the BMW X5 to start the engine; 3. Run the engine until the water temperature reaches 90 degrees, then turn off the engine; 4. Let the BMW X5 engine sit until the water temperature drops to normal temperature; 5. Pull the front hood release lever; 6. Lift the engine hood upwards; 7. Slowly unscrew the small water tank cap to release gas from the cooling system; 8. Top up the coolant to the MAX line. Precautions for coolant replacement: 1. After draining the coolant, tighten the drain switches on the cylinder block and radiator; 2. Fill the radiator with the specified coolant from the filler port until the coolant level in the reservoir reaches the specified height; 3. Close the radiator cap, run the engine to normal operating temperature, then shut it off and let it cool to room temperature; 4. Check the reservoir level again and add coolant as needed until no air bubbles appear in the reservoir during engine idle operation.

Can a Sedan Trunk Carry a Load of 600 Jin?

A sedan cannot carry a load of 600 jin. Generally, the load capacity of a sedan is around 500 jin, and carrying 600 jin would already constitute overloading for a sedan. Below are the impacts of overloading on a car: 1. Reduced braking performance and increased non-safe zone distance: There are many factors affecting a car's braking distance, among which the change in vehicle load directly influences the length of the braking distance. Overloaded cars, due to increased inertia, have longer braking distances. The extension of the non-safe zone distance can easily lead to traffic accidents. 2. Shortened lifespan of leaf springs and reduced vehicle passability: Due to overloading, the leaf springs are subjected to excessive force and continuously rebound during driving, which will shorten their lifespan. Moreover, the excessive load causes the vehicle to sink overall, reducing the ground clearance and diminishing the car's passability. 3. Accelerated tire wear and deformation: Car tires are designed and manufactured based on the total weight of the vehicle, with a considerable safety factor. However, when a car is overloaded, the tires bear excessive weight and deform. Simultaneously, increased friction also leads to a shortened tire lifespan.

How to Locate and Replace the Cabin Air Filter?

Methods to locate and replace the cabin air filter: 1. Some cabin air filters are located under the front windshield of the car, covered by a drainage trough. To replace the filter, first open the engine hood, remove the clips securing the drainage trough, and then take off the trough to reveal the cabin air filter; 2. For most household sedans, the cabin air filter is situated in the glove compartment under the windshield on the passenger side, making it extremely convenient to replace. Simply remove the glove compartment to access the cabin air filter inside. Functions of the cabin air filter: 1. Ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin; 2. Separates solid impurities such as dust, pollen, and abrasive particles from the air; 3. Provides strong and long-lasting moisture absorption; 4. Prevents the car windows from fogging up, ensuring clear visibility for drivers and passengers and enhancing driving safety; 5. Maintains clean air in the passenger compartment, preventing bacterial growth and creating a healthy environment.

Where is the car's tachometer located?

The car's tachometer is installed inside the instrument panel, symmetrically placed alongside the speedometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted, and converting this signal into a displayable rotational speed value. The tachometer's numbers range from 1 to 8, with the indicated number multiplied by 1000 representing the engine's RPM. The tachometer visually displays the engine's rotational speed under various operating conditions, allowing the driver to always be aware of the engine's performance, determine the optimal shifting time to coordinate with the gear and throttle position, maintain the best working condition, reduce fuel consumption, and extend the engine's lifespan.
