  • In non-diesel internal combustion engines, gasoline direct injection (GDI), also known as petrol . However, they do not inject during the exhaust cycle because doing so would waste fuel. Hence, all .. In the Hyundai Sonata model came with GDI engines, including a turbo charged litre that produces hp.

    It is a version of Gamma GDi with twin-scroll turbocharger, air guided intercooler, direct fuel injection system and dual.

    Fact about hyundai! The Hyundai logo is not just the letter "H" in the aval. It would be too easy. This emblem symbolizes the handshake of two people - a representative of the concern and a satisfied customer. In addition, in Korean, the word "hyundai" is translated as "modern".

    Hyundai Motor is showcasing two new turbocharged gasoline direct injected (T- GDI) engines, that boast exceptional efficiency and engaging.

    Best of all, GDI boosts gas mileage by up to 10 percent compared to a conventional engine. The new engine incorporates a high-pressure single-scroll turbocharger integrated within the exhaust manifold to improve operational efficiency. A variable intake system speeds up the flow of air into the cylinders at low speed while reducing the restriction at higher speeds. The benefits are more power and economy, However, certain octane fuels have caused exhaust valve erosion.

    Hyundai] Just as on the latest common rail direct injected diesels , the system on the Theta is capable of executing multiple fuel delivery pulses per ignition cycle. While all modern diesels uses multiple fuel pulses, this is a relatively new phenomena for gas engines. The split pulse strategy helps increase the exhaust temperature to heat up the catalytic converter faster.

    On modern engines, most of the emissions produced aside from carbon dioxide that is produced whenever the engine is running occur immediately following a cold start. Since the catalyst is ineffective until it heats up, getting it warmed up fast is key to eliminating the remaining emissions. Besides direct injection, Hyundai has added several other enhancements to the four cylinder.

    A variable intake system speeds up the flow of air into the cylinders at low speed while reducing the restriction at higher speeds. Variable phasing is also implemented on both of the camshafts, although the lift remains fixed.

    In combination with the increased compression ratio made possible by the DI, all of this helps to the boost the torque, which in turn improves driveability. According to Juriga, the low end torque is increased by 7 percent while the improvement is as much as 12 percent at the upper reaches of the rev band. Maximum output of the GDI engine in the dual exhaust SE model is now hp hp in the single exhaust GLS and Limited models at 6, rpm compared to hp at 6, rpm in the model.

    Peak torque, meanwhile, goes from pound-feet to pound-feet at 4, rpm. With Hyundai's emphasis on quality in recent years, the GDI four and all of the other engines being used in U. That's equivalent to , miles of driving at wide-open throttle.

    One of the Theta's that had already gone through this testing and had been torn down was on display adjacent to the cutaway engine. Final EPA fuel economy numbers aren't yet available but Hyundai is estimating a ten percent improvement. The company's officials made it clear that we could expect to see DI availability expanding in coming model years along with the addition of turbocharging and downsizing, a recent trend with engines whenever direct injection enters the picture.

    Large A new four-cylinder engine will help power Hyundai's drive towards becoming the fuel economy leader when it launches in the company's most popular car, the Sonata. Today, Hyundai unveiled the engine, which is built at Hyundai Motor Manufacturing of Alabama, at its Hyundai America Technical Center in Superior Township, Michigan, where it engineers, designs, tests and certifies vehicles sold in the U. In the all-new Sonata, consumers can expect an estimated best-in-class fuel economy of 35 miles per gallon in highway driving EPA certification pending.
