What does 660cc displacement refer to?

The displacement of a car refers to the total capacity of all the cylinders in the engine. For example, if a car engine has 4 cylinders, each with a capacity of 0.5L, then the engine's displacement is 0.5L × 4 = 2.0L. Alternatively, if a car engine has 6 cylinders, each with a capacity of 0.6L, then the engine's displacement is 0.6L × 6 = 3.6L. Introduction to displacement: The 'T' stands for Turbo, which is short for turbocharging, indicating an engine equipped with a turbocharging device. The 'L' stands for liters, the unit of displacement, and generally refers to a naturally aspirated engine. 2.0L means the engine has a displacement of 2.0 liters. Difference between 1.6L and 2.0L displacement: Depending on technical differences, a 2.0L car's performance is roughly between 1.4T and 1.8T. 1.6L indicates that the car is equipped with a naturally aspirated engine with a displacement of 1.6 liters. 1.6T indicates that the car is equipped with a turbocharged engine with a displacement of 1.6 liters. 2.0L means the car is equipped with a naturally aspirated engine with a displacement of 2.0 liters. 2.0T indicates that the car is equipped with a turbocharged engine with a displacement of 2.0 liters. Essentially, 2.0T adds turbocharging to a naturally aspirated 2.0L engine. Conversion of displacement: In Western countries, the general conversion is to multiply the displacement of a turbocharged engine by 1.4 to get the equivalent car displacement (for comparison with naturally aspirated L vehicles, facilitating tax management, etc.). In China, both 2.0T and 2.0L cars are taxed based on a 2.0 displacement for purchase tax purposes. However, the conversion standards may vary depending on different vehicle models.

Why Are Most Dismantled Car Speakers from Jieyang?

Not only dismantled car speakers but also other automotive parts are predominantly sourced from Jieyang, primarily because there are many recyclers of related items in this area. Here is a brief introduction about Jieyang: 1. Basic Information: Jieyang, also known as Rongcheng, is a prefecture-level city in Guangdong Province. It is renowned as the 'Coastal Zou Lu', 'Hometown of Chinese Painting', 'Hometown of Small Operas', 'Asian Jade Capital', and 'China's Hardware Base City'. 2. Geographical Location: Jieyang is an ancient city in eastern Guangdong, belonging to the Baiyue region during the Spring and Autumn and Warring States periods. After the founding of the People's Republic of China, it was successively under the jurisdiction of Chaoshan Special District, Eastern Guangdong Administrative Region, Shantou Special District, and Shantou City. In 1991, Jieyang County was abolished, and the prefecture-level Jieyang City was established, with Jiexi County placed under its jurisdiction.

How many points are deducted for looking down at the gear shift during the driving test (Subject 3)?

Looking down at the gear shift during the driving test (Subject 3) will result in a deduction of 100 points, as it is considered an incorrect sitting posture during the exam. Below are some key points to note for Subject 3: 1. Starting the car: First, adjust the seat and rearview mirror, check if the brakes and accelerator are functioning properly, and ensure the surrounding environment is safe before starting. 2. Turning left/right and making U-turns: Do not move the steering wheel within three seconds after turning on the turn signal, and ensure the speed matches the gear. 3. Passing bus stops and pedestrian crossings: Do not exceed 30 km/h, and look left and right to check for pedestrians. 4. Gear shifting operations: Complete gear shifting operations within the specified time and distance. 5. Changing lanes: Do not move the steering wheel within three seconds after turning on the turn signal, and complete the lane change within the specified time and distance. 6. Driving in a straight line: Maintain a speed of at least 40 km/h, keep steering wheel movement within 3 degrees, and complete the straight-line driving within the specified distance.

What causes abnormal noise from the rear wheel of an electric car?

Causes of abnormal noise from the rear wheel while driving: Car tire issues: Foreign objects stuck on the tire surface can cause a flapping sound while driving; small stones lodged in the tire grooves need to be removed promptly, or if the tire is punctured, uneven tire pressure among the four wheels can lead to abnormal noise; deformed or bulging tire treads, severe wear can produce a low thumping sound during driving. Brake pad and bearing issues: Excessively thin brake pads will produce a metal scraping sound when worn too thin; insufficient lubrication or excessive wear of bearings can cause wheel bearing noise.

Should the turn signal be kept on when pulling over?

When pulling over, the turn signal must be kept on to alert other traffic participants in advance that the vehicle is entering a parking state. Here are specific details about turn signals: 1. Introduction: The turn signal is an important indicator light that is activated when a vehicle turns to alert vehicles and pedestrians in front, behind, and on both sides. The turn signal uses a xenon lamp tube and is controlled by a single-chip microcomputer circuit, working continuously with alternating left and right flashes. 2. Function: The main purpose of the turn signal is to inform surrounding vehicles that you are about to change direction, prompting them to yield to avoid collisions. Therefore, whether turning, changing lanes, overtaking, starting, or parking, as long as your vehicle needs to steer away from the original lane, the turn signal should be activated in advance. This is a fundamental principle of safe driving.

Why does the car accelerate slowly with high RPM but the speed doesn't increase?

The car accelerates slowly with high RPM but the speed doesn't increase, which may be due to insufficient gasoline, insufficient cylinder pressure, ignition system failure, etc. Here is some extended information about gasoline: 1. Development background: In the mid-19th century, people did not yet recognize the importance of gasoline, and kerosene for lamps was widely used at that time. The petroleum refining process relied on simple distillation to separate the components of petroleum with different boiling points. Kerosene components had a higher boiling point and were safer to use in lamps, making them the main product of crude oil refining, while gasoline and other components were often burned as fuel. 2. Carcinogenic substances: On October 27, 2017, the International Agency for Research on Cancer (IARC) of the World Health Organization published a preliminary reference list of carcinogens, in which engine exhaust and gasoline were listed in the 2B category of carcinogens.
