What is the Principle of Car Movement?

The principle of car movement is as follows: 1. Rolling resistance: Rolling resistance is mainly caused by the relative deformation between the tires and the ground due to the car's gravity. The magnitude of resistance is directly related to the car's total weight, tire structure and pressure, and the quality and grade of the road surface. 2. Air resistance: Air resistance is formed by the friction between the car's surface and the air during movement, as well as the pressure of the oncoming airflow at the front of the car and the vacuum created by the air vortex at the rear. The magnitude of resistance is related to the car's frontal projected area, streamline length, and driving speed. 3. Uphill resistance: Uphill resistance depends on the car's total weight and the slope of the road. The greater the car's total weight and road slope, the greater the uphill resistance, and vice versa. Downhill resistance is the opposite, becoming the driving force for the car. 4. Inertial resistance: Inertial resistance only occurs during the car's variable-speed movement. According to the principle of inertia, when the car accelerates, the inertial resistance is opposite to the direction of movement. When the car decelerates, the stored kinetic energy tries to maintain the original speed, causing the car to coast forward.

What is the equivalent displacement of a 1.4t engine?

1.4t is equivalent to a naturally aspirated engine with a displacement of 1.8-2.0L. In fact, a 1.4t engine is a 1.4L naturally aspirated car engine equipped with a turbocharging device. The displacement is still calculated as 1.4L, but the driving force becomes stronger. Generally, the driving force of a turbocharged engine can reach the performance of a naturally aspirated car engine with about 1.3 to 1.5 times its displacement. The 't' refers to a turbocharged engine. The main function of turbocharging is to increase the engine's air intake, thereby improving the engine's power and torque, making the car more powerful. After installing a turbocharger, the maximum power of an engine can increase by 40% or even more compared to when it is not equipped with a turbocharger. This means that the same engine can output greater power after being turbocharged. In terms of performance, a 1.4T engine may have significant differences in power and torque output depending on different tuning. The tuning performance is roughly similar to that of a 2.0 naturally aspirated engine.

What are the dimensions of a car's front windshield?

Generally, the front windshield of a car is made of: 95% laminated glass, 2mm+2mm\3mm, usually smaller than 1300mm*2200mm; the rear windshield is made of: 95% tempered glass, 3.2mm~6mm, usually smaller than 1100mm*2000mm. Below is relevant information about windshields: 1. Laminated glass refers to a type of glass where a transparent adhesive plastic film is sandwiched between two or three layers of glass, combining the toughness of plastic with the hardness of glass, thereby increasing the glass's resistance to breakage. 2. Tempered glass refers to ordinary glass that has been quenched to create internal stresses, thereby strengthening the glass. When impacted and broken, the glass shatters into small pieces with blunt edges, reducing the risk of injury to passengers. 3. Zone-tempered glass is a new variety of tempered glass. Through special treatment, when it cracks upon impact, the cracks maintain a certain level of clarity, ensuring the driver's field of vision remains unaffected. Currently, car front windshields are mainly made of laminated tempered glass and laminated zone-tempered glass, capable of withstanding strong impacts.

What displacement is equivalent to a 1.3t engine?

A 1.3t engine is essentially a 1.3L naturally aspirated engine equipped with a turbocharger to enhance its power output and torque. Therefore, the actual displacement remains 1.3L, but in terms of power, a 1.3t engine is comparable to a 1.8L naturally aspirated engine. Different manufacturers have varying engine tuning approaches, but generally, a turbocharged engine of the same displacement delivers about 40% more power than a naturally aspirated one. In Western countries, the displacement of a turbocharged engine is often calculated by multiplying its actual displacement by 1.4. However, in China, only the direct numerical value is considered—both 1.3t and 1.3L engines are taxed based on the 1.3L displacement for vehicle purchase. Turbocharging not only provides stronger power than natural aspiration but also improves fuel efficiency, which is why many automakers have introduced small-displacement turbocharged engines. Generally, a larger displacement results in higher power output, but it also leads to higher fuel consumption. This is why off-road vehicles and sports cars typically have larger displacements. Smaller-displacement cars, on the other hand, offer more modest performance but better fuel economy. However, even with a small displacement, proper turbocharger tuning can enable these engines to outperform larger naturally aspirated engines in terms of power output.
