ENGINE introduce

The engine assembly, also known as the engine, is a machine that can convert one form of energy into another more useful form of energy, usually converting chemical energy into mechanical energy The electric motor, which converts electrical energy into machine energy, is sometimes applicable to both power generation devices and the entire machine including power devices. For example, gasoline engines, aviation engines, and automotive engines generally obtain kinetic energy through internal combustion of gasoline (diesel), so automotive engines are internal combustion engines. According to the different fuels used, they can be divided into gasoline engines and diesel engines. Gasoline engines and diesel engines have their own characteristics; Gasoline engines have high rotational speed, low quality, low noise, easy starting, and low manufacturing costs; Diesel engines have a high compression ratio, high thermal efficiency, and much better emission and economic performance than gasoline engines. Secondly, according to the piston motion mode, piston type internal combustion engines can be divided into two types: reciprocating piston type and rotary piston type. The former piston moves back and forth in a straight line in the cylinder, while the latter piston rotates in the cylinder. Thirdly, according to the number of cylinders, it can be divided into single cylinder engines and multi cylinder engines. Engines with only one cylinder are called single cylinder engines; An engine with two or more cylinders is called a multi cylinder engine. Modern car engines often use three cylinder, four cylinder, six cylinder, and eight cylinder engines. According to the arrangement of cylinders, they can be divided into single row, double row, and three row engines. The cylinders of a single row engine are arranged in a row, usually vertically, but sometimes they are arranged in a tilted or even horizontal position to reduce height. A double row engine arranges the cylinders in two rows, The angle between two columns)

What does the engine assembly include

The engine assembly includes a cylinder block, flywheel housing, transmission gear compartment, water pump, fan, transmission mechanism, timing gear, intermediate gear, filter, oil pan, oil pump, V-belt, crankshaft, connecting rod, piston, flywheel, etc

Volkswagen Weilan New Energy introduce

In terms of interior design, both Volvo from Scandinavia and Volkswagen from Germany are based on simplicity. The Volvo V60 is designed with a simple yet luxurious feel, while the Volkswagen NIO maintains Volkswagen's stable T-shaped layout. It is worth mentioning that the biggest highlight of the all-new B8 in terms of interior design comes from the integrated front air outlet design, which is not a big change, but very clever. In terms of seats, The sports seat configuration of the Volvo V60 is obviously higher, with electric adjustment for both the driver and passenger seats, as well as seat memory function for the driver's seat. In contrast, the Volkswagen NIO has more options for seat adjustment. The electric backrest adjustment for the driver's seat allows for manual adjustment of the front and rear height of the seat. In addition, the front seats also have manually adjustable leg rests and headrests that can be adjusted up and down in four ways, although the configuration is not as good as the V60, However, it can provide a more comfortable sitting position. As a station wagon, storage space is equally important. In this regard, both models have their own advantages. Firstly, in terms of storage compartment settings, the Volkswagen Weilan has a more diverse storage compartment compared to the Volvo V60; In addition, in terms of practicality, the Volkswagen NIO also has advantages. Taking the storage compartment next to the rear door as an example, the Volkswagen NIO can easily accommodate two bottles of mineral water, while the V60 looks somewhat impractical; However, the advantages of V60 come from the design of some storage compartments, such as the layered design of the glove box and the multiple folding designs of the rear center armrest, which enhance the practicality of these two parts through design
