Which Turn Signal to Use When Entering a Highway?

When entering a highway, you need to first turn on the left turn signal. While in the ramp, accelerate to over 60km/h, then pay attention to the traffic on the highway before gradually steering into the main lane. After exiting the highway, turn on the right turn signal and reduce your speed to 40km/h when entering the ramp. Precautions for driving on highways are as follows: Observe speed limit signs: Drive within the prescribed speed limits. Do not exceed the maximum speed limit and ensure you are in the correct lane for your speed. Additionally, speed limits on highways are segmented, requiring drivers to be particularly attentive to speed limit signs. Avoid sudden braking on highways: This prevents rear-end collisions caused by vehicles behind not braking in time, and even more severe multi-vehicle collisions. Stay focused while driving: Be mindful of guardrails to avoid scraping or even colliding with them due to insufficient safety distance or momentary distraction. Highways have wide lanes that can accommodate multiple vehicles simultaneously, so it's advisable to stay away from guardrails unless necessary.

What Causes High Engine Temperature Without Coolant Loss?

The following are the main reasons for high engine temperature without coolant loss: the impact of hot weather, overloaded air conditioning operation, and malfunctioning cooling components. Issues with the vehicle's cooling system, such as radiator leaks, insufficient coolant, degraded coolant, or blockages in the coolant circulation system. Symptoms of engine overheating: While driving, if white steam suddenly emerges from under the hood or the temperature gauge needle rapidly rises to the "H" (high) mark, it indicates that the engine temperature is too high. Emergency measures for engine overheating: In such a situation, immediately find a safe place to pull over, but do not turn off the engine right away. Keep the engine idling to continue dissipating heat, and open the hood to enhance cooling efficiency.

Why is there a shortage of automotive chips?

The shortage of automotive chips is due to the dual-driven increase in demand for new energy and autonomous driving. Here are the reasons: Vast automotive market: China has become the world's largest automotive market, with the trends of electrification and intelligence driving a significant increase in the number of automotive chips. Domestic production of automotive-grade chips has already established a scale foundation. However, domestic automotive-grade chips still face issues such as small-scale application in vehicles, long certification cycles, low technological added value, and high dependence on upstream industries. High costs: Whether for buses, trucks, traditional vehicles, new energy vehicles, or autonomous vehicles, semiconductor chips account for about 30% to 50% of the cost. Over the past decade, the proportion of costs attributed to semiconductor chips and electronic equipment has been increasing.

What is the Difference Between an Auto Trading Company and a 4S Store?

The following are the differences between a 4S store and an auto trading company: Different Vehicle Models: In terms of vehicle models, auto trading companies offer a wider variety because they source vehicles from different 4S stores to achieve higher sales volumes. Different Responsibilities: The primary responsibility of most auto trading companies is selling cars. When it comes to maintenance, car owners still need to go to 4S stores. Some auto trading companies also offer car repair and maintenance services to increase revenue. Car owners should be cautious when choosing to avoid issues during car maintenance. Different Odometer Readings: Cars purchased from auto trading companies often do not have zero odometer readings because these vehicles are usually driven by individuals during transportation, making it difficult to ensure safety. There is a higher risk of hidden issues with accident or faulty cars.

Where is the Engine Number?

The engine number is generally located on the outer surface of the engine cylinder block, or on the vehicle's nameplate or the nameplate inside the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number, like a person's ID number, represents each vehicle and contains very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to indicate information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose vehicles are required to display the professional manufacturer, model, and production number of the engine. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and engine models can be the same. The engine number, however, refers to the production number of the engine, and each engine can only have one unique engine number. Composition of the Vehicle Engine Number: Front Section: Includes the product series code, generation symbol, and regional or corporate code. Manufacturers can choose the appropriate letters as needed, but they must be approved and filed by the industry standard regulatory body. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and bore diameter. Rear Section: Composed of symbols for structural features and usage characteristics. Tail Section: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same series, the manufacturer selects an appropriate symbol. The rear and tail sections can be separated by a hyphen (-).

What is the Difference Between 2.0L and 1.5T?

Here are the differences between 2.0L and 1.5T: Different Engines: The 2.0L is a naturally aspirated engine, also known as an inline engine; the 1.5T is a turbocharged engine. Different Displacement: The displacement of the 2.0L is 2.0 liters; the displacement of the 1.5T is 1.5 liters. Car displacement refers to the volume of fluid inhaled or expelled per stroke or cycle. The car engine is the device that provides power to the car, serving as the heart of the vehicle. It determines the car's power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others.
