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

BAIC Weiwang 407EV New Energy introduce

In terms of appearance, although this car is a pure electric box truck, its appearance tends to be designed in the style of a concept car. Because it does not need to collide with the wind and dissipate heat like an oil burning motor vehicle, the front face of the car only uses a banner style black paint decorative panel, which is integrated with daytime running lights, making the entire truck look full of texture. Although the rear end is relatively square, the rich line design gives the rear end a certain sense of hierarchy, The rectangular tail lights with a vertical bar style are also very stylish, and the lighting effect is stunning. According to the vehicle positioning, the Weiwang 407EV can not only enter through the rear door in crowded streets, but also through the sliding door on the right side. The tail door adopts a 4/6 ratio split design, making it more convenient and flexible to get off and transport goods. The entire trunk volume of the car is 4.5 cubic meters, and the load capacity can reach 810kg
