The EcoBoost engine is one of the representatives of Ford's new power technology and has obtained 125 patents and patent applications in the United States. On the basis of traditional gasoline engines, it further adds three key technical advantages: in-cylinder direct fuel injection, turbocharging and dual independent variable valve timing systems, which not only ensures surging power output, but also optimizes fuel economy up to 20%, and carbon dioxide emissions are reduced by 15%. Ford EcoBoost engines combine the synergistic benefits of three key technologies: high-pressure direct fuel injection, advanced turbochargers and dual independent variable valve timing systems. The high-pressure in-cylinder direct injection system can accurately and quantitatively inject a small amount of fuel into each cylinder at a pressure of up to 200bar - the size of the oil droplets is generally less than 0.02mm, which is equivalent to 1/5 of the diameter of a human hair. The intake and exhaust camshafts of the EcoBoost engine are equipped with an independent variable valve timing system, which can optimize the air flow in the cylinder at different speeds, especially to improve the efficiency and performance of the engine under part load. On the other hand, in order to maximize driving pleasure, the EcoBoost engine can achieve high torque at low speeds and is responsive at high speeds. The EcoBoost engine's turbine uses a low-inertia rotor, which allows the engine to obtain maximum torque early at low speeds. Low-inertia rotors are more easily driven by exhaust gases. At lower engine speeds, less exhaust emissions can effectively spin the turbine, making turbine intervention more difficult to detect.
