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 S7 introduce

The all-new Audi S7 sports model is synonymous with "excellent performance" and "dynamic design". It is equipped with Audi's new 4.0-liter V8 TFSI twin turbocharged fuel direct injection engine, with a power output of up to 309 kilowatts (420 horsepower). Due to the use of new "cylinder on-demand" technology, the average fuel consumption per 100 kilometers is only 9.6 liters and 9.7 liters, respectively. With advanced chassis, lightweight body, and exquisite interior, Make the all-new Audi the perfect masterpiece in the sports car market The S7 is developed based on the Audi A7, which is also the first generation model of this series The S7 Sportback and the regular Audi A7 Sportback, although not significantly different in appearance, have added some masculine muscle lines on the basis of their original luxury, showcasing a full sense of sportiness, including the addition of lower turbulence on the front bumper, honeycomb shaped left and right lower air intakes, and the addition of body side skirts. The rear bumper also adds lower turbulence, and the exhaust tailpipe is changed to a dual sided four out setting, At the same time, it comes standard with 19 inch aluminum alloy wheels, fully boasting the title of S7 Sportback in terms of performance
