The United States in the last century, such as Chevrolet Camaro, Ford Mustang, Dodge Challenger, these large-scale American muscle cars are both the trend of the times and memories of this era. Because of the large displacements that have encountered the "winter" - Kemero suddenly dropped from the 7.4L peak period to today's 3.6L; Mustang entry threshold has been reduced to 2.3L; as "speed and passion 7" Alice Challenger, displacement is only 3.6L. When muscle cars mostly became movies and memories, more small-displacement cars were increasingly respected. The "small times" of 1.8T, 1.4T, and 1.0T quickly became the mainstream of this era. However, the small displacement, power must be significantly smaller? If you don't have a special pursuit for large displacements; if your desire for power is only an occasional "highway killing"; if you consider the fuel economy more, Fox's 1.0T Ecoboost 125 engine is a good choice. Speaking of this Ecoboost 125 engine, it must be said that the last pile belongs to its honor, a pile of praise, a pile of data, a pile of ... In short, it must be a lot of land, like a river, continuous unanimous praise. Such as: List of Ecoboost125 awards 1. 2012-2015 International Year Engine (8 awards for 4 consecutive years) 2, 2014-2015 Ward top ten engine 3, 2014 "China Heart" Top Ten Engines of the Year Ecoboost125 Advanced Technology 1, displacement is only 1.0L, the maximum power reached 92KW, and its power has reached a staggering 92KW/L. At the same level, there are almost no rivals; 2. Over Boost supercharged mode, making the engine get 200N/m torque, exceeding the level of most 2.0 naturally aspirated engines, and lasting up to 15 seconds. Together with Fox's consistently excellent chassis adjustment, overtaking becomes a breeze; 3, direct fuel injection technology makes fuel combustion more fully effective to reduce the engine's fuel consumption. At this time, the heart of this Ford Ecoboost 125 should be like this: However, the engine with this honor is also accompanied by such a question: When this Ecoboost 125 three-cylinder engine starts, it will produce jitter? At this time Ford's heart should be: In fact, whether it is a large-displacement engine or a small-displacement engine, it is more concerned about the heart of the car, whether the heart is strong, and whether a strong heart is easy to use. So long as it can pull the heart of Malaysia, even if it is small, it is a "big heart." The strong point of this 1.0T engine is that it not only saves oil in peacetime, it also generates strong power when it is critical, and it also avoids the shortcomings of the three-cylinder machine. Let's look at the strong factors of this 1.0T Ecoboost 125: 1, turbocharged 2, direct injection in the cylinder 3, double independent variable timing This Ecoboost 125 engine is turbocharged with a Class 1 exhaust gas turbocharger, which significantly increases the efficiency of gas charging, power, and torque up to 40%. In addition, the cylinder head integrates IEM---integrated exhaust manifolds to effectively increase thermal efficiency. At the same time, this turbo engine can instantly press the engine out of 200N/m power. This data is the same as a 2.0T engine. In short, Taiwan is a "small" heart that can play a role in pigs eating tigers. The EcoBoost engine injects high pressure fuel directly into the cylinder. The main advantage is that it achieves higher fuel efficiency and power output. It can spray precise quantities of small amounts of fuel into each cylinder at pressures up to 150 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. Therefore, even at low engine speeds, the engine can achieve “lean combustion†and “fully burn off every drop of oil†to ensure good dynamic response at low speeds. Conventional valve timing requires a balanced valve timing design to balance the power output across the full speed range. This sacrifices a certain amount of sacrifice between high-speed performance and low-to-mid-speed performance, while the dual independent change of the EcoBoost engine. Timing, according to the engine speed changes, continuous independent adjustment of intake and exhaust timing, to achieve the best intake efficiency, to achieve optimal power output within the full range of speed. In addition, the lightweight design of the engine body has reduced the weight of the engine and provided fuel economy; at the same time, it also reduced the production cost of the engine. As for the three-cylinder machine's jitter problem, Ford engineers solved it this way: Ford's engineers shifted the center of gravity of the 1- and 3-cylinder crank counterweights by 30 degrees to counterbalance the imbalance of the first-order reciprocating moment of inertia. This is equivalent to installing an invisible balance shaft, and this engine becomes smoother during power output. Today, the combination of small-displacement engines and turbines has become the mainstream in the automotive market. I believe it is mainly in the consideration of fuel economy. If there is such an engine, it is usually a fuel-saving mode of a “buy cartâ€; when it is required to move, it only requires deep stepping on the gas pedal, and the magical power that is sealed will instantly ignite and burst out with amazing energy. Since fish and bear's paws can be both, why not enter such an engine?
Automatic Cutting Machine is used
to cut long pipes, after cutting the pipe ends with a smooth blade, without
burr, which reduces manual grinding. It can load and unload the workpiece
automatically, so it reduces work intensity.
