Hyundai Sonata 2.0T 2011 Sedan
Hyundai Motor America from 2.0-liter Theta II turbocharged direct injection gasoline him (GDI) engines in 2011 Hyundai Sonata 2.0T 2010 New York Auto Show. With the addition of a new 2.0-liter Theta II turbocharged GDI, the new 2011 Hyundai Sonata offers a combination of unprecedented fuel consumption and segment-leading power – with the value estimated 34 mpg highway and 274 horses. Remarkably, the Hyundai Sonata 2.0T produces these parameters lead the industry on regular gasoline fuel … This is not necessary.
Hyundai’s new Sonata is Hyundai’s first vehicle to have the GDI technology and a turbocharger. At the end of the Hyundai 24 / 7 from version 2.0 product initiative (seven new models during the next 24 months), four dishes that are available with a combination of GDI or GDI and turbocharging. Turbocharging and GDI is one of the initiative “” Hyundai Blue Drive for the business environment to maintain its industry leadership in energy efficiency and sustainability.
“The Hyundai Sonata 2.0T was a very good example of what our strategy for the Blue Drive are products for consumers,” said John Krafcik, Hyundai Motor America President and CEO. “Think about the power – more than our competitors V6, using the gas that is better than competitive 4-cylinder models. We are not without compromise by Hyundai, the Sonata, and really shows this aspect of our business approach.”
Four-cylinder 2.0-liter turbocharged 2011 Sonata in GDI produces 274 horsepower at 6000 rpm and 269 lb-ft of torque, 1800-4500 rpm, with regular fuel. Hyundai Sonata 2.0T that gives 34 mpg city and 22 mpg highway (preliminary estimates). Hyundai’s turbocharged engine has a twin-scroll turbocharger, which when combined with the results of System GDI in the provision of instantaneous power. Twin-scroll turbocharger has traditionally been used in high-performance machine with more expensive, but as with GDI, Hyundai once again chooses to apply this technology effectively in a high volume of the most popular models.
2.0T engine is available in SE and Limited trim levels, with the 2.0T Limited obtained a further improvement, including
* Panoramic sunroof
* Hyper-silver alloy 18-inch
* Dual exhaust system
* Climbs driving speeding
Twin-scroll turbocharger and GDI
Twin-scroll turbocharger design has two entries divided by the wall in a split exhaust turbine casing, with two parts of the gas which is controlled by a wastegate. A twin-scroll turbo to get more energy from the exhaust of a turbo-scroll Thanks to one of the collector is divided. Cylinder twin-scroll design which separates the exhaust gas pulses interfere with each other causing Increasing the pressure distribution in the exhaust port and a more efficient delivery of energy to escape the gas turbine turbochargers.
For example, early in the intake stroke cylinder, and when the inlet and exhaust valves of the cylinder was opened (valve overlap), the cylinder had three starts with an open exhaust valve exhaust stroke. If the cylinder exhaust channel and three have been connected, the cylinder exhaust gas pulses will increase the pressure of gas three-cylinder one. This will reduce the induction of fresh air and increase the amount of hot residual gas in the cylinder. However, with twin-scroll turbocharger system, this interference is minimized.
Scan results from a superior design with double entry doors lead to a better distribution of pressure in the exhaust port and a more efficient delivery of energy from the turbine exhaust gas turbocharger. This allows more of the valve overlap, thus improving the quality and quantity of charge air entering each cylinder. In fact, with more valve overlap, the effect of flushing flow of exhaust gas can actually draw more air into the suction side. At the same time, the last draw low pressure exhaust gas to help fill each cylinder with a denser air charge. turbochargers increase the maximum is 17.4 psi.
Twin-scroll turbocharger design has several other advantages in the traditional single-scroll turbocharging system, including:
* Improved combustion efficiency
* Low speed engine efficiency
* Kinetic energy waste is not wasted or trapped
* Cooler temperatures cylinder
* Low temperature exhaust
* Purified air / fuel
* A better distribution of pressure in the exhaust and more efficient delivery of energy to the exhaust gas turbocharger turbine
