What is the difference between Big Ben and Little Ben?

The difference between Big Ben and Little Ben lies in their different models and positioning. Little Ben refers to the Mercedes-Benz C-Class, while Big Ben refers to the S-Class. The model indicators can be viewed at the rear of the car. Different Models: Mercedes-Benz sedan models are divided into the C-Class, E-Class, and S-Class. Among them, the C-Class is an entry-level model, the E-Class is a business sedan, and the S-Class is the high-end model of Mercedes-Benz. Simply put, Big Ben refers to the S-Class models, while Little Ben generally refers to the C-Class models. Typically, the rear of the car has indicators such as S600, C200, E350, etc. Different Positioning: The C-Class is for home use, positioned for general family use, equivalent to the Audi A4 or BMW 3 Series. The E-Class is a sporty luxury car, slightly higher than the C-Class, equivalent to the Audi A6 or BMW 5 Series. The R-Class is a large leisure travel series, based on the M-Class chassis, with four-wheel-drive versions available. Above the E-Class is the top luxury S-Class.

Why does the air conditioning stop cooling when the car is stationary?

When the car is stationary, the air conditioning stops cooling, but it works when the car is moving. Possible causes for this issue include: Damaged expansion valve: This prevents the formation of high pressure in the system before the expansion valve, causing the high-pressure refrigerant to fail to reach 150 Kpa. As a result, the evaporator behind the expansion valve cannot cool down, leading to ineffective air conditioning. Internal wear of the air conditioning compressor: This results in the pressure between the compressor and the expansion valve failing to reach 150 Kpa~200 Kpa, disrupting the normal circulation of refrigerant in the system and causing the air conditioning to underperform. Belt slippage: The air conditioning compressor is driven by the crankshaft via a belt. When the belt slips, the transmission efficiency of the compressor decreases. The most noticeable symptom is poor or even complete lack of cooling at engine idle or low speeds. Cooling only gradually resumes when the accelerator is pressed and engine speed increases. Damaged air conditioning compressor: The operation and idling of the compressor are controlled by its internal electromagnetic clutch. If the clutch malfunctions, it may cause the air conditioning to stop cooling at idle. Similarly, cooling performance only improves as engine speed increases.

In Subject 4, does the uphill yield to the downhill or the downhill yield to the uphill?

In Subject 4, the downhill yields to the uphill. Below is relevant information about Subject 4: Introduction: Subject 4, also known as the Subject 4 theoretical test or driver's theory test, is part of the motor vehicle driver's license examination. After the implementation of "Order No. 139 of the Ministry of Public Security of the People's Republic of China," the Subject 3 examination was divided into two parts: besides the road test, a safety and civilized driving knowledge test was added, commonly referred to as "Subject 4," which assesses "driving ethics." The test consists of 50 questions, primarily in the form of case studies, images, animations, etc., with a full score of 100 and a passing score of 90. Teaching objectives: Master the basic essentials of driving operations, possess fundamental vehicle control abilities, and be proficient in basic methods of driving on-site and on-road.

What Causes the Car to Roll Back in Subject 2?

Subject 2 rollback can be caused by either rolling backward or stalling. Below are detailed explanations of the causes and solutions: Rolling backward: When parking on a slope, even if the handbrake is pulled, the car may roll backward once the foot brake is released, which is due to the handbrake not being pulled tightly enough. The solution is to prevent the car from rolling backward. When starting the car, slowly lift the clutch with your left foot. When the car hood noticeably vibrates, gradually release the brake with your right foot. Once the brake is fully released, slightly lift the clutch a bit more with your left foot and hold it steady. Then, release the handbrake with your right hand, and the car will start moving forward. Stalling: When starting the car on a slope, if the left foot lifts the clutch too quickly, the car will stall. Lifting the clutch too quickly is the root cause of engine stalling. The solution is to prevent the car from stalling. When starting the car, the left foot must slowly lift the clutch and pause at the semi-engaged position. Once the clutch reaches the semi-engaged position, keep it steady, then gradually release the brake with your right foot.

Where is the fuel filling location for a scooter?

The fuel tank switch of a scooter is typically a vacuum negative pressure type, mostly installed directly under the fuel tank, while a few models have it mounted on the frame, connected to the fuel tank via a pipe. Additional information is as follows: Introduction: A scooter is a type of vehicle that bridges the gap between motorcycles and cars, serving as a popular means of transportation. In Taiwan, scooters are referred to as "civilian vehicles," while "military vehicles" denote cruisers, off-road vehicles, and sports cars. In Cantonese-speaking regions like Hong Kong, they are commonly called "sheep." Scooters are further categorized based on form and purpose, including children's scooters, disability vehicles, gasoline scooters, foldable scooters, golf carts, mini scooters, and three-wheeled scooters. Maintenance: Follow the manufacturer's manual for maintenance guidelines. This includes regular oil changes (every 1,000 kilometers), gear oil replacement (every 5,000 kilometers), periodic brake inspections or pad replacements, spark plug replacements, and battery capacity checks.
