What Causes the Engine to Make a Clanking Sound?

Engine abnormal noise causes are as follows: Insufficient engine oil: Leads to inadequate lubrication of components, resulting in wear sounds. Adding engine oil can resolve the issue. Poor fuel combustion: Low injection pressure, injector dripping, poor fuel atomization, and delayed fuel supply timing can all cause poor combustion leading to engine knocking. Remove and inspect the injector for adjustment, adjust fuel supply timing, and replace parts if necessary to meet specifications. Premature fuel supply timing: Fuel injection starts before the piston reaches the designated position, causing premature combustion. High-pressure gas in the cylinder impacts the piston, producing rhythmic sounds. Throttling down makes knocking obvious. Adjusting the fuel injection advance angle can solve the problem.

What is AMG?

AMG stands for Aufrecht-Melcher-Grossaspach. It is currently the official tuning company of Mercedes-Benz. AMG models: Includes models such as A-45-AMG, CLA-45-AMG, C-63-AMG, etc. Founding history: The history of Mercedes-AMG began in 1967, originating from two engineers who specialized in racing engines. Characteristics of AMG: AMG's modifications to the powertrain are not like those of other German professional tuning companies that replace the original engine with one of higher horsepower.

What is the Difference Between Reverse Curves and Continuous Curves?

Reverse curves and continuous curves differ in meaning, signage, and location. Different meanings: A reverse curve involves a sharp left turn followed by a sharp right turn, or vice versa, forming an "S"-shaped curve. The reverse curve traffic warning sign alerts drivers to slow down, with a safe driving speed not exceeding 60 km/h. A continuous curve consists of multiple consecutive left and right turns, such as right-left-right-left, essentially comprising multiple reverse curves. Different signs: The reverse curve is represented by a tilted "N" pattern, while the continuous curve is depicted by two connected tilted "N" patterns. Different locations: The reverse curve traffic warning sign is placed at an appropriate distance before two adjacent curves with opposite directions. The continuous curve traffic warning sign is positioned before a road with three or more consecutive curves. Reverse curve and continuous curve signs are commonly found on mountain roads, reminding drivers to slow down and be cautious of oncoming traffic. Improper driving or excessive speed can lead to severe consequences, including fatal accidents. Tips for driving on mountain curves: When encountering reverse curve or continuous curve signs, overtaking is prohibited. Drivers may honk appropriately to alert oncoming vehicles. Mountain curves often come with uphill or downhill sections. Maintain a safe distance. Use lower gears when climbing to leverage engine torque for better uphill performance. Similarly, use lower gears when descending to control speed via engine braking, as frequent braking can overheat and fail the braking system, potentially causing brake failure.

What does the automatic following system of driverless cars mainly rely on?

It determines the distance from the vehicle ahead through wireless signals. Composition of the automatic following system: Vehicle and mobile target carrying device. Working principle: The following car system sends a search signal through the wireless communication module, while the ultrasonic receiver starts timing. If the mobile target receives the wireless search signal, it immediately sends an ultrasonic signal. The triangular ultrasonic receivers of the small car successively receive the ultrasonic signals, and the CPU calculates the distance from the mobile target to the three ultrasonic receiving points based on the time each ultrasonic module receives the signal. The position of the mobile target can be determined using the trilateration algorithm. If the calculated distance is greater than the set distance, the motor is controlled to move toward the target direction. If the calculated distance is less than the set distance, the motor is controlled to stop, thereby achieving the automatic following function of the car.

At least 1 year. You must wait at least one year after obtaining a car driver's license before you can apply for a motorcycle license. Class D license: A Class D license allows you to drive three-wheeled motorcycles with an engine displacement exceeding 50ml or a maximum design speed exceeding 50km/h, as well as two-wheeled motorcycles with an engine displacement exceeding 50ml or a maximum design speed exceeding 50km/h, and motorcycles with an engine displacement of 50ml or less and a maximum design speed of 50km/h or less. Class E license: With a Class E license, you can legally drive two-wheeled motorcycles with an engine displacement exceeding 0.5L or a speed exceeding 50km/h, and you can also drive vehicles permitted by a Class F license. With a Class F license, you can legally drive light motorcycles with an engine displacement below 0.5L or a speed below 50km/h.
