Chinese name: Ford motor with Ecoboost engine: new power killer: high-pressure direct injection of fuel. Consumers: the three killer weapons to improve fuel economy benefit consumers, with small displacement and strong power. Ford EcoBoost engine combines the synergistic advantages of three key technologies: high-pressure direct injection of fuel, advanced turbocharger and dual independent variable valve timing system. Each technology has its own advantages, and the integration of the three technologies reflects the design concept of the EcoBoost engine, including: optimized engine efficiency-effectively improving fuel economy by 20% and reducing carbon dioxide emissions by 65,438+05%-richer driving pleasure-strong torque at low speed and excellent reverberation in a wide speed range, and the advantages brought by small displacement-enjoying the output power of the traditional high-displacement engine. However, Ford EcoBoost engine benefits consumers. Ford EcoBoost engine can improve fuel economy and reduce carbon dioxide emissions because its combustion system can fully burn in a more efficient and cleaner mode. Its core technology is a set of high-pressure fuel in-cylinder direct injection system, which can inject a small amount of fuel into each cylinder under the pressure of up to 200 bar-the size of oil droplets is generally less than 0.02 mm, which is equivalent to 1/5 of the diameter of human hair. The intake and exhaust camshafts of Ford EcoBoost four-cylinder engine are equipped with independent variable valve timing systems, which can optimize the air flow in the cylinder at different speeds, especially improve the efficiency of the engine and the performance under part load. On the other hand, in order to maximize driving pleasure, Ford EcoBoost engine can achieve high torque at low speed and be sensitive at high speed. Thanks to the advanced turbocharging technology, its built-in small low inertia rotor can run at a high speed of more than 200,000 revolutions per minute. The carefully selected turbine ensures that the engine can get the maximum torque at the speed of 1 1,500 rpm or lower, and at the same time, the turbine lag is controlled to the minimum, which can accelerate quickly and realize rich driving pleasure. The turbine is carefully matched to ensure that the EcoBoost engine maintains strong power and sensitive reverberation when the speed reaches 5000 rpm, so its peak power output range is wider. Ford EcoBoost new power technology can be widely used in various vehicles, from small cars to heavy trucks. Compared with expensive hybrid cars and pure electric vehicles, Ford EcoBoost engine can make consumers really afford it. One of the key advantages of Ford EcoBoost engine with small displacement and strong power is to effectively reduce the engine displacement, and replace the traditional naturally aspirated engine with a small displacement engine without sacrificing any power output. Generally speaking, the turbocharger can increase the torque by 50%, so it can significantly reduce the engine displacement and optimize the fuel consumption and exhaust emissions while maintaining strong power. In addition, the small displacement engine can reduce internal friction, reduce pumping loss and total weight, thus optimizing efficiency and preheating the car faster. Therefore, Ford EcoBoost engine can show the advantages of low fuel consumption and strong power under various driving conditions such as urban roads and highways. Ford S-MAX and Galaxy European Land Rover Aurora have taken the lead in carrying this engine. Ford Mondeo, the first vehicle equipped with this engine in China market, made its debut at the 20 10 Beijing Auto Show. Mondeo-Zhisheng, equipped with a 2.0-liter EcoBoost GTDI inline four-cylinder engine and PowerShift, was launched on March/8th, 201/year.
