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

Porsche Macan introduce

The Porsche Macan is a mid size SUV The term "Macan" originates from the Indonesian translation of "tiger". As a mid size SUV of Porsche, the Macan adopts the chassis of the Audi Q5, equipped with Michelin tires [1]. Porsche's family style front face is not lacking, and its unique hatchback design is fundamentally different from the Q5. In terms of design, it tends to be more sporty, making it look like a crossover car The launch of Macan fills the gap of the Porsche brand in the mid size SUV market, sparking a new round of competition in the market with high brand value, sporty styling, and differentiated customization services The entry-level Macan model is equipped with a 2.0-liter inline four cylinder turbocharged engine, with a maximum power of 173Kw; The mid-range configuration is equipped with a 3.0L V6 twin turbocharged engine, with a maximum power of 250Kw; The flagship model is equipped with a 3.6L V6 twin turbocharged engine with a maximum power of 294kw. On November 10, 2018, the all-new Porsche Macan was officially launched
