Reasons for Abnormal Noises When Passing Over Speed Bumps

What are the precautions for using a water sprinkler truck?

Here are the precautions for using a water sprinkler truck: 1. Water source: Requirements for the water source When using rivers or ponds as water sources, ensure that the end of the suction pipe is fully submerged in water. Choose relatively clean water sources to avoid sucking in stones, excessive mud, sand, or floating debris, which can easily clog the filter screen. If the water source is shallow, deepen the suction area beforehand to ensure no debris is present and to prevent air from entering. 2. Suction pipe: The suction pipe must maintain a vacuum When the water sprinkler truck is drawing water, the suction pipe system must maintain a certain level of vacuum to draw water into the tank. The suction pipe system must be reliably sealed, with no damage to the hose or cracks in the hard pipe. 3. Gear shifting: Shift gears while stationary Whether before drawing water or before sprinkling, the power take-off (PTO) must be engaged while the vehicle is stationary. During gear shifting, release the clutch slowly to avoid potential damage to the PTO.

Why Does the Driving Range Increase the More You Drive?

Many components operate in a relatively tight state initially, inevitably resulting in slightly higher resistance. After driving for a period, these components gradually reach their optimal operating condition, reducing resistance and subsequently lowering fuel consumption, which in turn increases the driving range. Key considerations include the following two points: 1. Pay attention to fuel consumption: Driving range = remaining fuel in the tank / fuel consumption. The more significant influencing factor is fuel consumption. Different fuel consumption values can lead to vastly different driving range estimates. Since vehicle operating conditions vary, fuel consumption actually changes based on the driver's demands. 2. Comprehensive fuel consumption: A comprehensive fuel consumption value can be set during production, such as using the NEDC cycle as the initial benchmark. After the owner takes possession of the vehicle, fuel consumption settings can be adjusted using various methods, such as instantaneous or steady-state fuel consumption. Calculating the driving range based on instantaneous fuel consumption can cause rapid fluctuations, potentially making the range appear to increase the more you drive. In contrast, using steady-state fuel consumption averages the fuel consumption over a longer period for more stable estimates.

Can I get a motorcycle license while taking the C1 license test?

You cannot obtain a motorcycle license while taking the C1 license test. According to regulations, you cannot apply for two types of driving licenses within one year. You can only take one of the tests first. If you want to take another driving license test, you must wait until the one-year probation period of the first license is over before applying for an additional license or taking another test. When applying for the additional license, you need to bring the license you have already obtained. The C1 test includes four subjects: traffic regulations and related knowledge, field driving, road driving, and safe and civilized driving knowledge. Passing standards: Traffic regulations and related knowledge (Subject 1) — written test, full score is 100; Field driving (Subject 2) — on-site, actual vehicle; Road driving (Subject 3) — highway or simulated field, actual vehicle; Safe and civilized driving knowledge — written test, questions mainly in the form of cases, pictures, animations, etc., with question types including true/false, single-choice, and multiple-choice, totaling 50 questions, full score is 100.

Is it recommended to replace the original car screen with an Android screen?

Nowadays, when purchasing a car, it generally comes with an original multimedia display screen. However, the navigation system on the original car screen is troublesome to update, and it usually only supports MP3 playback, while videos and other formats cannot be played. Under suitable conditions, it is recommended to replace it with an Android display screen for better functionality. Below is an introduction to the car central control system: 1. Central locking system: There are many types of central locks installed in cars, but their basic components mainly include door lock switches, door lock actuators, and door lock controllers. 2. Switches: Most central lock switches consist of a master switch and sub-switches. The master switch is installed on the driver's side door, allowing the driver to lock or unlock all doors in the car. Sub-switches are installed on other doors and can control a single door individually. 3. Actuators: The central lock actuator is used to execute the driver's commands to lock or unlock the doors. Door lock actuators come in three types: electromagnetic, DC motor, and permanent magnet motor. Their structures all work by changing polarity to reverse the direction of movement, thereby performing the locking or unlocking action.

What are the main contents of the secondary maintenance of a car?

The main contents of the secondary maintenance of a car are: 1. Replace the oil in the oil pan, and clean the oil pan, oil pump, and oil collector with kerosene; 2. Check and adjust the valve clearance; 3. Tighten the bolts of the cylinder head, intake and exhaust manifolds, and muffler, and check whether the gaskets of the above parts are intact; 4. Check the clutch and adjust the free travel of the clutch pedal as needed; 5. Check the fastening condition of each part of the transmission and gear shifting mechanism. The secondary maintenance of a car, in addition to the primary maintenance operations, mainly involves checking and adjusting safety parts that are prone to wear or deformation after a certain period of use, such as steering knuckles, steering rocker arms, brake shoes, suspension, etc., as well as disassembling and inspecting tires, performing tire rotation, checking and adjusting the working condition of the engine and exhaust pollution control devices, etc. These maintenance operations are performed by maintenance companies.

Where to Add Engine Oil to a Car?

Engine oil is added from the oil filler port on the left side of the engine. To perform operations such as changing the oil, simply unscrew the oil filler cap in the reverse direction. When reinstalling the oil filler cap, lubricate the cap opening with oil from the dipstick, then smoothly tighten it in the clockwise direction until it is securely in place. Basic steps for adding engine oil: 1. After the car is parked and the engine is turned off for about ten minutes, pull out the dipstick and wipe the oil traces clean with a cloth. 2. Reinsert the dipstick into the dipstick tube, then pull it out again to check the oil traces. Normally, the oil level should be between the upper and lower marks on the dipstick, slightly above the middle line. 3. If the oil level is below the lower mark, it indicates insufficient oil, and you should add oil immediately. While adding oil, continuously pull out the dipstick to monitor the oil level. 4. When topping up the oil, try to use the same type of oil as the one already in the engine to avoid mixing different brands or grades of oil.
