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

桑塔那 introduce

In the late 1990s, Shanghai Volkswagen Co., Ltd. developed the "Shanghai Santana 2000" sedan, aiming to sprint towards the 21st century and challenge the future, sparking a "new Santana" whirlwind on the coast of the East China Sea in China The Santana brand has been deeply rooted in people's hearts in China for 20 years, but unfortunately, shopping malls are like battlefields. The current automotive market is full of gunpowder. The Santana 2000 was discontinued on January 31, 2004, and the replacement model, the Transcender (Santana 3000), was officially produced on February 1, 2004. Shanghai Dazhong claimed that the title of the "Transcender" of the Santana 3000 model is called "Modern Classic Car", which means "Modern Technology. Classic Model", On the one hand, it is because the Santana has become a classic model, and the "Transcender" continues the brand spirit of the Santana; On the other hand, the Transcender also adopts relatively advanced technologies, such as variable frequency air conditioning
