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

BYD L3 introduce

From the perspective of BYD's product system, the F3 is gradually moving towards the low-end, the G3 is moving towards the mid-range, and the L3 will be the first bullet in BYD's mid to high end models. The positioning of this car will be close to or slightly higher than the currently available compact car G3. With BYD's consistent high cost-effectiveness, it is expected to compete in the higher end automotive market and potentially impact the current compact car market dominated by joint venture brands The L3 front face features a wide and thick dual horizontal bar intake grille that is simple and atmospheric; The overall shape of the front headlights adopts a tear eye design, while the smoked black design adds a sporty style to the entire vehicle. The engine hood also adopts the popular raised design, making the overall style very linear and powerful. It can be seen that the L3 has surpassed the past in appearance design, forming a distinct style. The tail lights are designed with popular LED lights, which exude a grand, fashionable, elegant temperament, and reliable safety and quality
