1. And made of stainless steel exhaust turbine housing, and multiple dual-scroll on a patent pending one-piece design
2. And waste gate turbocharger controller uses electric motors instead of mechanical controls

Thanks to the turbine housing integrated stainless steel with stainless steel exhaust manifold, and not just the weight and cost of casting significantly reduced, and improve the durability of the turbine housing as well.

Adapted by electric motor used for the gate, and increased pressure is controlled precisely. And reduce the pressure again when you increase the turbo is not necessary to open the gate through the waste, which improves fuel efficiency. In addition, starting in the cold, and waste is still open gate results in a faster catalyst light-off to reduce exhaust emissions.

GDI and fuel delivery system will contribute to improving fuel efficiency and reduce emissions. This shorter and more direct path to deliver the fuel to allow more control over the fuel mixture at the moment optimal, thereby improving efficiency. Fuel injection is driven by the camshaft, and high-pressure pump operating at pressures up to 2175 lbs / square inch. Direct injection is also used higher than normal compression ratio of 9.5:1, while a superb 137 hp per liter. , Distributed by the heads of the piston to increase the efficiency of combustion in the cylinder.

Designs twin scroll turbocharger two entrances to the exhaust gas divided by the walls of division inside the turbine housing, with each of the sections of gas controlled by the gate of waste. And retrieves the twin-turbo moved more energy from the exhaust of a single-scroll turbocharger by a division multiple. Dual slider design that separates the gas cylinders exhaust pulses interfere with each other, leading to improved distribution of pressure in the exhaust ports and a more efficient delivery of energy from the exhaust gas turbine turbochargers.

For example, in the beginning of the stroke dealt with single-cylinder, and at every entrance and exhaust valves of the cylinder and one open (valve overlap period), three-cylinder actually starts in the exhaust stroke with the open exhaust valve. If the exhaust passages of the cylinder and one that was connected to three, and the pulse of exhaust gas from a cylinder of three would increase the pressure of the cylinder and the rear one. This would reduce the instigation of fresh air, and increase the amount of hot gas remaining inside the cylinder. However, with the setup dual scroll turbocharger, this intervention is minimized.

2.0T engine will be available on the SE and reduce the level of limited, with access to additional promotions, Ltd. 2.0T, including:

Panoramic Sunroof

Double-scroll turbocharger and technology GDI

Hyundai Motor America President and CEO 2.0T Sonata is a great example of what our drive to play Blu-strategy for consumers. Think of it more than any horse V6 of our competitors, with better gas mileage than any competitive 4-cylinder model. Were not masses of prejudice to the Hyundai Sonata and explains the reality of this aspect of the approach to our work.

2.0-liter GDI engine turbo four-cylinder Sonata in 2011 and produces 274 horsepower at 6000 rpm and 269 lb-ft of torque rpm with the 1800-4500 regular fuel. 2.0T Sonata will deliver 22 city miles per gallon highway, 34 mpg (preliminary estimates). Hyundais Turbo engine features a dual-scroll turbocharger that when side by side with GDI system results in the delivery of instantaneous power. Traditionally, twin scroll turbochargers used on more expensive high-performance engines, but as is the case with glandular], Hyundai again chosen for the application of this technology in the volume of high-efficiency model for the most popular.

For the first time in America, Hyundai Motor 2.0-liter Theta II turbo direct-injection gasoline (GDI) engine in the Sonata in 2011 New York Auto Show today. GDI engine with the addition of the all-new 2.0-liter Theta II Turbo, 2011, the new Sonata provides an unprecedented array of efficiency in the use of fuel and a leader in the energy sector with an estimated 34 mpg highway rating, 274 hp. What is striking is not required, and Sonata 2.0T produces these standards industry-leading fuel fuelpremium normal.

The Sonata is Hyundai’s first car from both GDI technology and turbocharger for. By the end of Hyundais 24 / 7 version 2.0 product initiative (seven new models in the next 24 months), and four nameplates are available with GDI or a combination of GDI and the turbocharger. Turbocharging and GDI are part of a blue Hyundai, and the company’s environmental initiative to continue to lead the industry in fuel efficiency, and sustainability.
