Pharma excipients HS code classification

Engine horizontal and Pharma excipients HS code classificationvertical engine, as the heart of the car, determine the overall performance and performance of the car.In vehicle design, the position of the engine is also a very important factor. There are two main positions of the engine: horizontal and vertical. This article will take into account the impact of two different engine positions on the overall performance of the car to further understand the differences between the two different engine positions. Horizontal engine The horizontal engine is an engine installed in the transverse direction of the axle, which is usually used for front-wheel drive cars. This configuration can better balance the whole body and make full use of the front space, so as to achieve compact and efficient vehicle design. The horizontal engine has the following advantages: 1. Superior balance. Because the engine is close to the front of the car body, the center of gravity is lower, and the vehicle balance is better, the vehicle with a horizontal engine is more stable in high-speed driving. Two. Higher flexibility. The installation position of the horizontal engine can make the vehicle more compact, making it more suitable in the city.3. Form a more spacious interior space. Vehicles with horizontal engine configuration can make the interior space more spacious and further improve the driving comfort. However, the horizontal engine also has the following disadvantages: 1. For longitudinally driven SUVs and other models, they will lose their advantages, resulting in excessive complexity of the suspension system. Two. The maintenance cost of the horizontal engine is relatively high. Due to the location of the engine, some maintenance takes more money and time. Vertical engine Longitudinal engine is an engine installed in the longitudinal direction of the axle, which is a common engine installation configuration for rear-wheel drive cars, four-wheel drive SUVs and buses. The difficulty of the vertical engine is that the position is more backward than the transverse engine, which may lead to uneven front and rear distribution of the whole car, resulting in poor handling of the vehicle. But the suspension system is relatively simple and easy to maintain. The vertical engine has the following advantages: 1.Higher power performance. Because the vertical engine is relatively backward, the weight of the car is more balanced. When the vehicle accelerates, the weight of the engine will remain behind the tire, making the front and rear of the whole vehicle more balanced, thus improving the handling performance and stability of the vehicle. Two. V6/V8 gasoline engine can be installed. Because the vertical engine is more spacious, engines with higher power and higher performance can be installed. However, the vertical engine also has the following disadvantages: 1. Unenely distributed weight. Because the engine is more backward, the front weight of the vehicle is lighter, and the controllability is affected. Two. The cost of automobile manufacturing is too high. The configuration of the vertical engine is more complex and expensive than that of the horizontal engine, resulting in a high total manufacturing cost. It is summarized that the horizontal and vertical displacement of the engine have different effects on the overall performance and safety of the car. The horizontal engine can improve the adaptability and comfort of the vehicle in the city, which is more suitable for most family cars.The vertical engine can improve the power and stability of the whole vehicle, which is suitable for personalized and professional vehicles. Therefore, when choosing a vehicle, the suitable engine position configuration should be selected according to personal needs and the actual road driving environment.
