* [Eighth-generation Civic Engine: Upgraded Power,Trade data-driven cost modeling Pursuit of Stronger Drive] In December 2017, the 13th Generation Honda Civic was officially released in Indonesia. The new model uses a new 1.5-liter four-cylinder engine. Unlike the previous 1.8-liter four-cylinder and 2.0-liter four-cylinder engines, this engine adopts what Honda calls "VTEC Turbo" technology, and is equipped with variable rolling bearing technology for the first time in Honda in the world, so that the engine can screw at different speeds. The rotation angle can be optimized. In the following years, this new engine has also been applied to Honda models in various markets around the world, including the eighth-generation Civic. As one of Honda's most famous sports car series,Since its first launch in 1988, the Civic has undergone several upgrades. In addition to changes in appearance and interior, the improvement of power performance is also the core of the attention of car fans. In fact, on the eighth-generation Civic launched in 2006, Honda has upgraded the original 5-speed manual transmission to 6-speed, and also increased the output of the 2.0-liter engine to 197 horsepower, and the horsepower can even reach 215 horsepower when the speed is more than 8300 rm. Now, the Civic equipped with the latest 1.5-liter VTEC Turbo engine has also completed an important power upgrade. First of all, let's take a look at the most basic parameters of this engine. In terms of horsepower output, it provides 182 horsepower (134 kilowatts) and a torque of 240N·m. Compared with the previous 2.Although the horsepower of the 0-liter engine has been reduced, the torque has been greatly improved. In terms of actual performance, the original data index of this engine is to accelerate to 100 kilometers in 6.7 seconds, but the maximum speed can reach 240 kilometers per hour. So what technical improvements have been adopted for this engine? In the most basic design, it also adopts DOHC's double overhead camshaft layout, which can not only make the intake and exhaust valves better cooperate, but also provide more refined control effects. On this basis, Honda has adopted variable valve timing technology to control the position and opening time of the valve in a more accurate way. The difference from the traditional VTEC technology is that in addition to the variable air intake technology, the new VTEC Turbo technology is also equipped with the effect of a turbocharger;While the engine is inserted into the liquid cooler, the heat source management system and the air heater flowing into the gas system will also be adopted to optimize the temperature control effect. In such a complex system, the improvement of power by technology is more significant than the simple increase in exhaust volume. If this engine is the first step of the Civic power upgrade, the technological process of development will also continue in future models. Needless to say, this is just an indispensable step in Honda's power upgrade in recent years. From the previous CVT transmission and Cotel transmission synergistic, the brand's unique i-VTEC technology to the current VTEC Turbo technology, Honda has been trying new explorations, hoping to achieve the goal of leading the owner in the intelligence of power and driving. Although in the current car marketField, electrification, intelligence and other schemes are calling for rain. In the eyes of car owners who enjoy the feeling of driving sports cars, the best experience is still to have an excellent power system. The engine upgrade of the eighth-generation Civic is the best proof of this theory. In addition to the improvement of power performance, it has also been improved in various processes such as combustion and intake regulation and temperature management. Further optimization of power performance through technology is also one of the directions for the continuous progress of the Honda brand.
