Should You Press the Clutch or Brake First in Subject 2?

How many points will be deducted for parking on the emergency lane of the highway?

Parking on the emergency lane of the highway will result in a deduction of 6 points and a fine. Below are some precautions for driving on the highway: 1. Before entering the highway: Before driving on the highway, it is essential to conduct a thorough inspection of the vehicle. First, check the fuel level. 2. Check the tire pressure: While driving, tires undergo compression and expansion, known as tire deformation. This phenomenon is more pronounced when the tire pressure is low and the speed is high, leading to abnormally high internal temperatures. This can cause the rubber layer to separate from the cover layer or result in the rubber on the outer tread breaking and flying off, leading to a tire blowout and potential accidents. Therefore, before driving at high speeds, the tire pressure should be slightly higher than usual. 3. Check the braking performance: The braking performance of a vehicle is crucial for driving safety. When driving on the highway, extra attention should be paid to braking performance. Before setting off, drive at a low speed to test the brakes. If any abnormalities are detected, repairs must be carried out immediately; otherwise, it could lead to a serious accident.

How to Check Mercedes-Benz Model Codes?

Methods for identifying Mercedes-Benz model codes: Observe the letters at the front of the vehicle. The A-Class represents compact hatchbacks, C-Class denotes compact sedans, E-Class indicates mid-size sedans, S-Class signifies luxury sedans, M-Class refers to SUVs, G-Class designates off-road vehicles, V-Class stands for multi-purpose vans, SLK represents compact sports cars, CLK indicates mid-size sports cars, SL stands for luxury sports cars, CL denotes luxury coupes, and SLR refers to supercars. The numbers in the middle of the model code (e.g., 280, 300, or 500) indicate engine displacement, representing 2.8L, 3L, and 5L respectively. For example, S600L translates to a luxury, 6L-displacement, extended-length sedan. Beyond sedans and SUVs, Mercedes-Benz also offers coupes, AMG models, convertibles, electric vehicles, and MPVs. AMG models are straightforward—adding "AMG" to any model doesn't change its classification but signifies enhanced performance through modifications by Mercedes-Benz's in-house tuning division. For instance, the Mercedes GLC AMG remains a mid-size SUV but commands a significantly higher price. For coupes, Mercedes currently sells only the CLA and CLS, positioned as compact and mid-to-full-size models respectively. In the convertible sports car segment, Mercedes offers just two models: the AMG GT and the SL-Class AMG. For MPVs, Mercedes-Benz has the V-Class and Vito, both manufactured by Fujian Benz and classified as mid-to-full-size MPVs, with the V-Class positioned as the premium option. Regarding electric vehicles, Mercedes currently has two pure EV models: the EQC (mid-size SUV) and EQS (full-size sedan).

Can a Naturally Aspirated Engine Be Modified with a Supercharger?

If the original vehicle is equipped with a naturally aspirated engine, it cannot be fitted with a supercharger. Here are the reasons why a naturally aspirated engine cannot be modified into a supercharged one: 1. Since it involves modifying a production vehicle, it is not only prohibited by law in China, but the modification process is also extremely labor-intensive, requiring numerous changes. Specifically, there is no installation space for a supercharger, no supporting components, and the engine control unit lacks the necessary programming for forced induction. 2. Turbocharged engines are not without flaws. While they offer improved fuel efficiency to some extent, they suffer from turbo lag during acceleration, resulting in less linear power delivery compared to naturally aspirated engines. Additionally, the maintenance costs of turbocharged engines are higher than those of naturally aspirated engines in the same class. 3. Turbocharged engines are used in racing, such as in F1, where a 1.5L engine can produce up to 1000 horsepower. However, this comes at the expense of fuel consumption, and when large turbos spool up to the engine's power band, the sudden surge of power can be difficult to control. Consequently, F1 eventually abandoned turbocharged engines. Nevertheless, turbocharged engines have found widespread adoption in civilian vehicles, and with advancements in automotive technology, modern turbocharged engines have significantly improved in terms of durability and smoothness. This trend is expected to continue as a major direction for future automotive engine development. 4. A supercharger is a type of turbocharger. It consists of two tightly meshed blades connected to the crankshaft via a belt. A typical supercharger is about the size of a standard toolbox and is usually mounted on top of the engine. The working principle of a supercharger is similar to that of a turbocharger, both relying on compressing air. However, since the supercharger is directly connected to the engine, there is no delay in power delivery.

What is the Function of a Cylinder Head?

Here is a relevant introduction to the cylinder head: The main function of the cylinder head is to seal the cylinder, forming a closed space, which allows the piston to properly compress fuel and the air-fuel mixture to generate power. The structure of the cylinder head is relatively complex, generally including intake valve seat holes, exhaust valve seat holes, valve guide holes, spark plug mounting holes, intake passages, exhaust passages, camshaft bearing holes, etc. Cylinder heads are typically made of gray cast iron, alloy cast iron, or aluminum alloy, and they are complex box-shaped components. Depending on their structural type, cylinder heads can be classified into integral, block, and monobloc types. Requirements for cylinder heads: 1. High stiffness and strength, resistant to deformation, ensuring sealing effectiveness. 2. Reasonable layout to ensure the normal operation of the engine. 3. Manufacturing processes must meet standards to prevent friction with other components. Symptoms caused by a damaged cylinder head: 1. Abnormal engine vibration. 2. Reduced vehicle power, unresponsiveness to throttle input, or even loss of power. 3. Engine knocking. Things to note during routine vehicle maintenance: 1. Perform maintenance as scheduled. 2. It is advisable to use high-quality fuel. 3. Replace consumable items such as engine oil and oil filters in a timely manner.

What Causes the Oil Can Light to Illuminate?

The oil can light indicates the engine oil warning light. Reasons for the oil light illumination include insufficient oil level, excessively high engine temperature, damaged oil pump components, and clogged oil filter. The details are as follows: Insufficient oil level: Insufficient oil volume or air ingress preventing oil pumping can lead to a drop in oil pressure. Excessively high engine temperature: An overheated engine may thin the oil, causing significant loss and resulting in decreased oil pressure. Damaged oil pump components: Worn or damaged oil pump parts, improper assembly, or excessive clearance can prevent the oil pump from delivering adequate oil. Another factor is improper clearance between the crankshaft and bearing shells. Clogged oil filter: Blockages in the oil filter or oil pickup screen. Upon noticing the oil light, immediate inspection is necessary to avoid unnecessary malfunctions. Check the engine oil level and lubrication circulation system. Some motorcycles trigger this warning light when oil is insufficient or lubrication is inadequate.
