An engine is a machine that can convert other forms of energy into mechanical energy, including, for example, an internal combustion engine (gasoline engine, etc.), an external combustion engine (Stirling engine, steam engine, etc.), an electric motor, and the like. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is applicable to both the power generating device and the entire machine including the power unit (eg, gasoline engine, aero engine). The engine was first born in the UK, so the concept of the engine is also derived from English, and its original meaning refers to the kind of "mechanical device that generates power."
The engine can be said to be the most important part of the car, and its layout has a major impact on the performance of the car. For cars, the engine layout can be easily divided into front, center and rear. Most of the models currently on the market use front-engines, and the mid- and rear-engines are only used on a few performance sports cars.
Of course, depending on the type of engine placement, it can also be divided into horizontal and vertical engines.
1. The engine valve drive mechanism adopts a hydraulically supported ball rocker arm structure. Compared with the hydraulic lifter type valve drive mechanism generally used on general gasoline engines, the novel valve drive mechanism has the advantage of relatively small friction torque. The required driving force is also small, which can effectively reduce engine power consumption and reduce fuel consumption.
2. In order to effectively reduce the weight of the whole vehicle, the 1.4-liter gasoline engine adopts an aluminum alloy cylinder, which has achieved a very obvious lightweight effect.
3. The special metal material and special plastic processing air intake pipe are used to replace the traditional metal air intake pipe, which not only receives the lightweight effect, but also can effectively reduce the intake pipe wall resistance, improve the intake efficiency and increase the engine power.
4. The cutting-type connecting rods processed by advanced technology are used to cut the large-end holes of the processed connecting rods with special breaking equipment, instead of the sawing and grinding process originally used. This makes it possible to use the saw-toothed "Huff" face of the break link to ensure an absolutely accurate fastening position, thereby reducing friction and extending the life of the link.
