In the endless scarcity of energy today, the engine is known as the car's heart, who can let the heart to reduce energy consumption at the same time play a stronger power, who will be able to win the future of the larger market.
    As a member of the German Volkswagen Group's latest EA888 series of engines, the FSI petrol direct injection engine is a variety of mid-range sedan models that have been used recently in the Volkswagen Group. It is understood that the current in the country, only Audi and other high-end models have this heart, and rumors that Octavia will also be configured such a heart. If the domestic Octavia really configured this heart, it will become the first application of TFSI engine in the high-class cars.
    For FSI gasoline direct injection technology, many people are relatively unfamiliar. In order to let everyone have a clear understanding, I collected some of the FSI gasoline direct injection technology for your reference.
    FSI gasoline direct injection technology concept
    Volkswagen FSI direct injection technology is a direct innovation in the field of direct injection gasoline engine technology. FSI is the abbreviation of FuelStratifiedInjection, which means fuel stratification. The use of this technology gives the FSI engine more robust power, lower fuel consumption, greater output power and torque compared to conventional engines.
    FSI direct injection technology in the same displacement to achieve the engine power and fuel economy, the perfect combination of today's automotive industry, the most mature engine technology, the most advanced fuel direct injection technology, and led the development trend of gasoline engines.
    The working principle of FSI gasoline direct injection technology
    FSI engine according to the engine load conditions, basically can automatically choose two operating modes. In the low load for the stratified thin burning, when the high load is homogeneous combustion.
    At low load (stratified lean combustion), the throttle is half-open, the fuel system is injected with fuel in the engine compression stroke. The special piston top is designed so that the inhaled air and the injected fuel form a roll, forming only around the spark plug To achieve the theoretical air-fuel ratio of the combustion of air-fuel mixture, to ignite the entire combustion chamber mixture; and other parts of the combustion chamber is rich in air-rich high air-fuel mixture, so the formation of lean combustion.
    At the full load (homogeneous combustion), the amount of fuel injected is precisely controlled according to the amount of inhaled air. The fuel and air are injected into the cylinder simultaneously and atomized to allow the mixture of the stoichiometric air-fuel ratio to fill the combustion chamber evenly. , The formation of homogeneous combustion, full of combustion so that the engine power to be most vividly play. And the evaporation of the fuel and the mixture cooling to remove the knock generated. That is, in the case of uniform combustion, in the high power output and torque at the same time pay a lower fuel consumption.
    Advantages of FSI Gasoline Direct Injection Technology
    The advantage that the FSI engine that injects fuel directly into the cylinder is superior to the conventional engine that injects fuel into the intake manifold:
    One control is easier and easier
    Two save fuel consumption
    Three power is significant
    Four can output higher torque and power
    Five provinces fuel consumption
    In our daily exercise, always can not avoid according to road conditions, constantly changing the grade, and FSI engine can let us more deeply appreciate the reduction in the number of shift, control more easily. Compared with the traditional engine, a 15% reduction in fuel consumption means that the engine economy increased by 15%, FSI is the continuous improvement of the overall results of the technology. For the public environment, this technology is more in the future to reduce vehicle exhaust emissions laid a good foundation.
    In addition, the FSI engine, which gets rid of the traditional gasoline engine injection mode, electronically controls fuel injection in the cylinder, FSI gasoline direct injection technology is committed to play every drop of fuel all the potential, compared to other engines at the same time To ensure complete combustion more thoroughly, while reducing fuel consumption at the same time provide a rapid driving force. FSI gasoline direct injection technology and turbocharging technology is a combination of cutting-edge engine model, which makes the engine output power and torque more robust, which brought the driving force to enjoy the driving.
    The Volkswagen FSI turbocharged engine, with similar direct injection engine fuel injection of the common features, but also has a turbocharger to create a powerful driving force. Power boost is very obvious, highlight the torque output area, excellent response to provide the driver with the perfect control pleasure, but also no mechanical turbocharger power lag phenomenon.
    Application of 1.8TFSI Gasoline Direct Injection Technology
    FSI gasoline direct injection engine, represents the world's top automotive engine technology level. Not long ago, it began to apply to the Volkswagen Group of a variety of high-end car models. 1.8TFSI gasoline direct injection engine in China for the first time, but also Skoda global product line for the first time.
    1.8TFSI gasoline direct injection engine use, so that Shanghai Volkswagen Octavia sedan to create a domestic intermediate car gasoline direct injection of a new era. It can maintain excellent fuel economy under the premise of the output of the peak power of 118KW, which is generally used in general B-class 2.4 displacement engine compared to no less, even more than the general B-class car.
