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

Audi S8 introduce

The Audi S8 is the sporty performance version of the Audi A8. The all-new Audi S8 is only modified from the new A8 in terms of exterior and interior details. In terms of exterior design, the Audi S8 is not much more aggressive than the regular A8. In terms of power, the all-new Audi S8 is equipped with a 4.0TFSI twin turbocharged engine, with a maximum power of no less than 520 horsepower and a continuous torque output of 650N · m at 1700rpm-5500rpm. Audi launched the first generation S8 as early as 1994, As the sport version of Audi's top luxury car A8, it applied all of Audi's top technologies at the time, such as an all aluminum body frame and full-time four-wheel drive. Luxury cars were originally aimed at high-end demand, and most of them should be aimed at rear seat users, so the sport version S8 that leans towards driving pleasure is definitely only aimed at a few out of a few. Audi had been optimistic about this niche market for a decade, and now continues to make every effort to launch the new generation S8, And still playing the role of "Audi's cutting-edge technology collection"
