Famous picture engine:Easily uncover the mystery of the engine and DigiPlusexplore the working principle of the engine. The most mysterious part of the car is the engine. We only hear the roar and the feeling of pushing back when accelerating, but we know very little about the real working principle and details. This article will take the famous engine as an example to reveal the mystery of the engine to readers and lead you to understand and explore the working principle of the engine. The engine model of the famous picture is Theta II GDI 2.4, and the GDI is Gasoline Direct Injection, which means gasoline direct injection system. It is a more advanced and efficient gasoline engine system. Let's start with the basic working principle of the engine and discuss it step by step. The working principle of the engine. The working principle of the engine is toAfter the body fuel and gas are mixed, the high-temperature and high-pressure gas produced by spark detonation pushes the piston, drives the wheels and consumes fuel. The most important parts are the combustion chamber and piston. The combustion chamber is the core part of the engine, where all combustion takes place. The design and size of the combustion chamber have a great impact on the performance and emissions of the engine. The piston is a moving part of the engine. The piston can be understood as a cylindrical part with the same diameter as the cylinder wall, which moves back and forth in the cylinder. The force generated by the piston during compression and combustion is transmitted to the crankshaft, which ultimately drives the wheels. The working principle of GDI engine GDI engine is very different from the traditional gasoline engine. Traditional gasoline engines use indirect combustion, that is, fuel and air are mixed first before entering the engine combustion.The GDI engine adopts a direct injection method, that is, the fuel is directly sprayed into the combustion chamber, mixed with air and burned. In the GDI engine, the fuel enters the cylinder through multiple injectors, first evaporates the fuel into atomized state, and then ignites the fuel mixture under high-pressure ignition to produce high-temperature and high-pressure gas and push the piston. Due to the direct injection of fuel, the GDI engine can improve combustion efficiency, generate higher pressure and power, and reduce emissions. In addition to direct fuel injection, the GDI engine also adopts some other technologies, including variable valve timing and variable gasoline pressure, to further improve performance and fuel economy. In summary, the engine is the most important part of the car, and its working principle and design have an important impact on the performance and fuel economy of the car.The GDI engine adopts direct fuel injection and some other advanced technologies to improve performance and fuel economy, bringing a broader prospect to the development of the automotive industry.
