HS code reference for mineral exports

Brief description of the difference between L-type and HS code reference for mineral exportsT-type engines. The engine is the heart of the car and one of the core components. It can make the vehicle run. Among the types of engines, L-type and T-type engines are two common ones, so what is the difference between the two engines? Here will be a simple comparison of them. L-type engine L-type engine is a general type of engine in which the pistons on both sides of the left and right are arranged in an L-shape, which is named only because it looks like the letter L. L-type engines can be divided into a variety of arrangements such as four-cylinder, six-cylinder, eight-cylinder and twelve-cylinder. Its biggest feature is that it can achieve a large cylinder diameter in the hood of a smaller car. In addition, because the L-type engine is mostly used for sports vehicles and racing cars, it is also very dynamic and more refreshing to drive.The name of the T-type engine T-type engine comes from its T-shaped arrangement. The T-type engine has only three cylinders, which is very space-saving and can meet the lightweight requirements of modern cars. In addition, due to the internal design of the T-type engine, it is more superior in terms of performance and off-road ability. For example, some off-road vehicles will use T-engines, because this engine can support low-speed rotation and low-speed driving. However, due to the small number of cylinders in the T-type engine, the output power and power are not as good as those of the L-type engine, and the ride experience will be slightly inferior. The difference between L-type and T-type engines 1. The structural form of the L-type engine is composed of two rows of cylinders arranged on the same side, and the arrangement is "7" or "work", while the T-type engine is composed of three cylinders, and the arrangement is T-shaped.Two. The installation position of the L-type engine is different from that of the T-type engine. The long axle of the L-type engine is parallel to the driving direction of the vehicle, that is, perpendicular to the direction of the vehicle; while the T-type engine changes the long axis of the engine to parallel to the driving direction of the vehicle through horizontal installation. 3. The center of gravity position The center of gravity of the L-type engine is in the center of the vehicle, which is relatively uniformly distributed, while the center of gravity of the T-type engine moves backwards, resulting in a certain uneven weight distribution at the rear of the vehicle. Four. In comparison with the power output, the L-type engine has more cylinders, so its output power and power are stronger; while the T-type engine pays more attention to the ability of low-speed rotation and low-speed driving, and some off-road vehicles use T-type engines. 5. Space utilization L-type engine due to the arrangementThe design can achieve a large cylinder diameter in the hood of a smaller car, with better space utilization; while the T-type engine is very suitable for the needs of modern cars to be lighter and space-saving due to the small number of cylinders. Generally speaking, the application scenarios of L-type engine and T-type engine are different. Which type of engine to choose depends entirely on the usage and needs of the vehicle. No matter which one, the key is to choose reasonably to give full play to their performance.
